2008-10-17BGE showstopper bug fix: Benoit Bolsee
- Reset hit object pointer at end of frame of touch sensor to avoid returning invalid pointer to getHitObject(). - Clear all references in KX_TouchSensor::m_colliders when the sensor is disabled to avoid loose references. - Test GetSGNode() systematically for all KX_GameObject functions that can be called from python in case a python controller keeps a reference in GameLogic (bad practice anyway).
2008-09-28enable -noaudio option, so it actually works (and doesn't get overwritten by ↵Erwin Coumans
a game flag). audio initialization delays startup of game engine 2 seconds add -nojoystick commandline option: it takes 5 seconds everytime to start the game engine, while there IS no joystick. In other words: blender -noaudio -nojoystick improves workflow turnaround times for P - ESC from 7 seconds to 1 second! Improved Bullet soft body advanced options, still work-in-progress. Make sure to create game Bullet soft bodies from scratch, it is not compatible with last weeks builds.
2008-09-24Created a KX_SoftBodyDeformer for real-time soft bodies.Erwin Coumans
Added SetDeformer/GetDeformer() to KX_GameObject. Store mapping between graphics/soft body vertices (work-in-progress) Real-time soft body integration is still very premature, but for a quick preview, see this testfile: http://bulletphysics.com/ftp/pub/test/index.php?dir=blender/&file=soft_test.blend
2008-09-21BGE bug fix: dupligroup scale not correctly applied to bullet shape.Benoit Bolsee
2008-09-05BGE set visible actuator, option to set visibility recursively to make ↵Campbell Barton
managing visibility for collections of objects a lot easier. BGE Python api's ob.setVisible() also takes an optional recursive arg thats off by default
2008-09-05Merge of first part of changes from the apricot branch, especiallyBrecht Van Lommel
the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.
2008-08-28didnt build before committiong this small change :/ Campbell Barton
isLight() is apricot only. Add this back when GLSL is merged to avoid conflicts.
2008-08-28BGE Bugfix, lights were not being removed when their gameobject was removed ↵Campbell Barton
causing odd shadows to hang about the scene.
2008-08-21BGE bug #17491 fixed: BGE, Dupli instance with different scale, massive ↵Benoit Bolsee
slowdown. The root cause of this bug is the fact that Bullet shapes are shared between duplicated game objects. As the physics object scale is stored in the shape, all duplicas must have the same scale otherwise the physics representation is incorrect. This fix introduces a mechanism to duplicate shapes at runtime so that Bullet shapes are not shared anymore. The drawback is an increased memory consuption. A reference count mechanism will be introduced in a later revision to keep Bullet shape shared between duplicas that have the same scale.
2008-07-30Bugfixes: fix for two memory leaks related to dupligroups,Brecht Van Lommel
and a missing reference count in the trackto actuator. This showed up as leaked pose data, but actually the whole object was not being freed.
2008-07-29Game Engine: alpha blending and sortingBrecht Van Lommel
======================================= Alpha blending + sorting was revised, to fix bugs and get it to work more predictable. * A new per texture face "Sort" setting defines if the face is alpha sorted or not, instead of abusing the "ZTransp" setting as it did before. * Existing files are converted to hopefully match the old behavior as much as possible with a version patch. * On new meshes the Sort flag is disabled by the default, to avoid unexpected and hard to find slowdowns. * Alpha sorting for faces was incredibly slow. Sorting faces in a mesh with 600 faces lowered the framerate from 200 to 70 fps in my test.. the sorting there case goes about 15x faster now, but it is still advised to use Clip Alpha if possible instead of regular Alpha. * There still various limitations in the alpha sorting code, I've added some comments to the code about this. Some docs at the bottom of the page: http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/ Merged some fixes from the apricot branch, most important change is that tangents are now exactly the same as the rest of Blender, instead of being computed in the game engine with a different algorithm. Also, the subversion was bumped to 1.
2008-07-29BGE patch: fix support of group hidden layer in dupli group instantiation: ↵Benoit Bolsee
only the objects in layers matching the group layer mask will be instantiated. This is equivalent to the 3D view
2008-07-26BGE patch: support runtime duplication of groups. Adding an object with ↵Benoit Bolsee
Dupligroup option set will cause the group to be instantiated. No special actuator is needed for this feature, just put dupligroup objects in inactive layers and add them dynamically
2008-07-21BGE patch: Optimization of bullet adaptation layer - part 1.Benoit Bolsee
First batch of optimizaton of the bullet adaptation layer in the BGE. - remove circular motion state update. - optimization of physic adaptation layer for bullet: bypass unecessary conversion of rotation matrix to quaternion and back. - remove double updates during object replication.
2008-07-19BGE patch: Relink actuators with target within group when duplicating group; ↵Benoit Bolsee
generalize protection against object deletion for all actuators that point to objects. Certain actuators hold a pointer to an objects: Property, SceneCamera, AddObject, Camera, Parent, TractTo. When a group is duplicated, the actuators that point to objects within the group will be relinked to point to the replicated objects and not to the original objects. This helps to setup self-contained group with a camera following a character for example. This feature also works when adding a single object (and all its children) with the AddObject actuator. The second part of the patch extends the protection against object deletion to all the actuators of the above list (previously, only the TrackTo, AddObject and Property actuators were protected). In case the target object of these actuators is deleted, the BGE won't crash.
2008-07-18BGE patch: support for partial hierarchy in dupligroup instantiation; ↵Benoit Bolsee
removal of links that point to inactive objects during group instantiation. This situation corresponds to a group containing only a portion of a parent hierarchy (the Apricot team needed that to avoid logic duplication). The BGE will instantiate only the children that are in the group so that it follows the 3D view more closely. As a result, the logic links to the objects in the portion of the hierarchy that was not replicated will point to inactive objects (if the groups are stored in inactive layers as they should be). To keep the logic system consistent, these links are automatically removed. This last part of the patch is a general fix that could go in 2.47 but as this situation does not normally occurs in pre-2.47 games, it is not needed.
2008-07-17BGE patch: use the Blender convention to duplicate groups in the BGE so that ↵Benoit Bolsee
the objects will be created with the location and orientation as in Blender. Note that the BGE handles scaling in a parent tree differently than Blender. To avoid discrepencies between the 3D view and the BGE, use only isotropic scaling on all your objects except the leaf objects (i.e. without children) that can have anisotropic scaling
2008-07-17BGE bug fix (good for 2.47): fix logic reconnection after replication. The ↵Benoit Bolsee
old method was matching the bricks by name assuming they are unique but it is not always the case, especially with the new dupligroup feature. The new method matches the bricks by objects and position.
2008-07-16BGE patch: DUPLIGROUP option supported in BGE.Benoit Bolsee
Blender duplicates groups in the 3D view at the location of objects having the DUPLIGROUP option set. This feature is now supported in the BGE: the groups will be instantiated as in the 3D view when the scene is converted. This is useful to populate a scene with multiple enemies without having to actually duplicate the objects in the blend file. Notes: * The BGE applies the same criteria to instantiate the group as Blender to display them: if you see the group in the 3D view, it will be instantiated in the BGE. * Groups are instantiated as if the object having the DUPLIGROUP option (usually an empty) executed an AddObject actuator on the top objects of the group (objects without parent). * As a result, only intra-group parent relationship is supported: the BGE will not instantiate objects that have parents outside the group. * Intra-group logic bricks connections are preserved between the duplicated objects, even between the top objects of the group. * For best result, the state engine of the objects in the group should be self-contained: logic bricks should only have intra-group connections. Use messages to communicate with state engines outside the group. * Nested groups are supported: if one or more objects in the group have the DUPLIGROUP option set, the corresponding groups will be instantiated at the corresponding position and orientation. * Nested groups are instantiated as separate groups, not as one big group. * Linked groups are supported as well as groups containing objects from the active layers. * There is a difference in the way Blender displays the groups in the 3D view and how BGE instantiates them: Blender does not take into account the parent relationship in the group and displays the objects as if they were all children of the object having the DUPLIGROUP option. That's correct for the top objects of the group but not for the children. Hence the orientation of the children objects may be different in the BGE. * An AddGroup actuator will be added in a future release.
2008-07-10Sync with Apricot Game EngineBrecht Van Lommel
============================= * Clean up and optimizations in skinned/deformed mesh code. * Compatibility fixes and clean up in the rasterizer. * Changes related to GLSL shadow buffers which should have no effect, to keep the code in sync with apricot.
2008-07-08BGE logic patch: new "Add" mode for Ipo actuator, several corrections in ↵Benoit Bolsee
state system. New Add mode for Ipo actuator ============================= A new Add button, mutually exclusive with Force button, is available in the Ipo actuator. When selected, it activates the Add mode that consists in adding the Ipo curve to the current object situation in world coordinates, or parent coordinates if the object has a parent. Scale Ipo curves are multiplied instead of added to the object current scale. If the local flag is selected, the Ipo curve is added (multiplied) in the object's local coordinates. Delta Ipo curves are handled identically to normal Ipo curve and there is no need to work with Delta Ipo curves provided that you make sure that the Ipo curve starts from origin. Origin means location 0 for Location Ipo curve, rotation 0 for Rotation Ipo curve and scale 1 for Scale Ipo curve. The "current object situation" means the object's location, rotation and scale at the start of the Ipo curve. For Loop Stop and Loop End Ipo actuators, this means at the start of each loop. This initial state is used as a base during the execution of the Ipo Curve but when the Ipo curve is restarted (later or immediately in case of Loop mode), the object current situation at that time is used as the new base. For reference, here is the exact operation of the Add mode for each type of Ipo curve (oLoc, oRot, oScale, oMat: object's loc/rot/scale and orientation matrix at the start of the curve; iLoc, iRot, iScale, iMat: Ipo curve loc/rot/scale and orientation matrix resulting from the rotation). Location Local=false: newLoc = oLoc+iLoc Local=true : newLoc = oLoc+oScale*(oMat*iLoc) Rotation Local=false: newMat = iMat*oMat Local=true : newMat = oMat*iMat Scale Local=false: newScale = oScale*iScale Local=true : newScale = oScale*iScale Add+Local mode is very useful to have dynamic object executing complex movement relative to their current location/orientation. Of cource, dynamics should be disabled during the execution of the curve. Several corrections in state system =================================== - Object initial state is taken into account when adding object dynamically - Fix bug with link count when adding object dynamically - Fix false on-off detection for Actuator sensor when actuator is trigged on negative event. - Fix Parent actuator false activation on negative event - Loop Ipo curve not restarting at correct frame when start frame is different from one.
2008-07-04BGE logic update: new servo control motion actuator, new distance constraint ↵Benoit Bolsee
actuator, new orientation constraint actuator, new actuator sensor. General ======= - Removal of Damp option in motion actuator (replaced by Servo control motion). - No PyDoc at present, will be added soon. Generalization of the Lvl option ================================ A sensor with the Lvl option selected will always produce an event at the start of the game or when entering a state or at object creation. The event will be positive or negative depending of the sensor condition. A negative pulse makes sense when used with a NAND controller: it will be converted into an actuator activation. Servo control motion ==================== A new variant of the motion actuator allows to control speed with force. The control if of type "PID" (Propotional, Integral, Derivate): the force is automatically adapted to achieve the target speed. All the parameters of the servo controller are configurable. The result is a great variety of motion style: anysotropic friction, flying, sliding, pseudo Dloc... This actuator should be used in preference to Dloc and LinV as it produces more fluid movements and avoids the collision problem with Dloc. LinV : target speed as (X,Y,Z) vector in local or world coordinates (mostly useful in local coordinates). Limit: the force can be limited along each axis (in the same coordinates of LinV). No limitation means that the force will grow as large as necessary to achieve the target speed along that axis. Set a max value to limit the accelaration along an axis (slow start) and set a min value (negative) to limit the brake force. P: Proportional coefficient of servo controller, don't set directly unless you know what you're doing. I: Integral coefficient of servo controller. Use low value (<0.1) for slow reaction (sliding), high values (>0.5) for hard control. The P coefficient will be automatically set to 60 times the I coefficient (a reasonable value). D: Derivate coefficient. Leave to 0 unless you know what you're doing. High values create instability. Notes: - This actuator works perfectly in zero friction environment: the PID controller will simulate friction by applying force as needed. - This actuator is compatible with simple Drot motion actuator but not with LinV and Dloc motion. - (0,0,0) is a valid target speed. - All parameters are accessible through Python. Distance constraint actuator ============================ A new variant of the constraint actuator allows to set the distance and orientation relative to a surface. The controller uses a ray to detect the surface (or any object) and adapt the distance and orientation parallel to the surface. Damp: Time constant (in nb of frames) of distance and orientation control. Dist: Select to enable distance control and set target distance. The object will be position at the given distance of surface along the ray direction. Direction: chose a local axis as the ray direction. Range: length of ray. Objecgt within this distance will be detected. N : Select to enable orientation control. The actuator will change the orientation and the location of the object so that it is parallel to the surface at the vertical of the point of contact of the ray. M/P : Select to enable material detection. Default is property detection. Property/Material: name of property/material that the target of ray must have to be detected. If not set, property/ material filter is disabled and any collisioning object within range will be detected. PER : Select to enable persistent operation. Normally the actuator disables itself automatically if the ray does not reach a valid target. time : Maximum activation time of actuator. 0 : unlimited. >0: number of frames before automatic deactivation. rotDamp: Time constant (in nb of frame) of orientation control. 0 : use Damp parameter. >0: use a different time constant for orientation. Notes: - If neither N nor Dist options are set, the actuator does not change the position and orientation of the object; it works as a ray sensor. - The ray has no "X-ray" capability: if the first object hit does not have the required property/material, it returns no hit and the actuator disables itself unless PER option is enabled. - This actuator changes the position and orientation but not the speed of the object. This has an important implication in a gravity environment: the gravity will cause the speed to increase although the object seems to stay still (it is repositioned at each frame). The gravity must be compensated in one way or another. the new servo control motion actuator is the simplest way: set the target speed along the ray axis to 0 and the servo control will automatically compensate the gravity. - This actuator changes the orientation of the object and will conflict with Drot motion unless it is placed BEFORE the Drot motion actuator (the order of actuator is important) - All parameters are accessible through Python. Orientation constraint ====================== A new variant of the constraint actuator allows to align an object axis along a global direction. Damp : Time constant (in nb of frames) of orientation control. X,Y,Z: Global coordinates of reference direction. time : Maximum activation time of actuator. 0 : unlimited. >0: number of frames before automatic deactivation. Notes: - (X,Y,Z) = (0,0,0) is not a valid direction - This actuator changes the orientation of the object and will conflict with Drot motion unless it is placed BEFORE the Drot motion actuator (the order of actuator is important). - This actuator doesn't change the location and speed. It is compatible with gravity. - All parameters are accessible through Python. Actuator sensor =============== This sensor detects the activation and deactivation of actuators of the same object. The sensor generates a positive pulse when the corresponding sensor is activated and a negative pulse when it is deactivated (the contrary if the Inv option is selected). This is mostly useful to chain actions and to detect the loss of contact of the distance motion actuator. Notes: - Actuators are disabled at the start of the game; if you want to detect the On-Off transition of an actuator after it has been activated at least once, unselect the Lvl and Inv options and use a NAND controller. - Some actuators deactivates themselves immediately after being activated. The sensor detects this situation as an On-Off transition. - The actuator name can be set through Python.
2008-06-25BGE patch: Add automatic support for armature driven shape keys.Benoit Bolsee
To take advantage of this feature, you must have a mesh with relative shape keys and shape Ipo curves with drivers referring to bones of the mesh's parent armature. The BGE will automatically detect the dependency between the shape keys and the armature and execute the Ipo drivers during the rendering of the armature actions. This technique is used to make the armature action more natural: the shape keys compensate in places where the armature deformation is uggly and the drivers make sure that the shape correction is synchronized with the bone position. Note: This is not compatible with shape actions; BLender does not allow to have Shape Ipo Curves and Shape actions at the same time.
2008-06-22BGE patch: add state engine support in the logic bricks.Benoit Bolsee
This patch introduces a simple state engine system with the logic bricks. This system features full backward compatibility, multiple active states, multiple state transitions, automatic disabling of sensor and actuators, full GUI support and selective display of sensors and actuators. Note: Python API is available but not documented yet. It will be added asap. State internals =============== The state system is object based. The current state mask is stored in the object as a 32 bit value; each bit set in the mask is an active state. The controllers have a state mask too but only one bit can be set: a controller belongs to a single state. The game engine will only execute controllers that belong to active states. Sensors and actuators don't have a state mask but are effectively attached to states via their links to the controllers. Sensors and actuators can be connected to more than one state. When a controller becomes inactive because of a state change, its links to sensors and actuators are temporarily broken (until the state becomes active again). If an actuator gets isolated, i.e all the links to controllers are broken, it is automatically disabled. If a sensor gets isolated, the game engine will stop calling it to save CPU. It will also reset the sensor internal state so that it can react as if the game just started when it gets reconnected to an active controller. For example, an Always sensor in no pulse mode that is connected to a single state (i.e connected to one or more controllers of a single state) will generate a pulse each time the state becomes active. This feature is not available on all sensors, see the notes below. GUI === This system system is fully configurable through the GUI: the object state mask is visible under the object bar in the controller's colum as an array of buttons just like the 3D view layer mask. Click on a state bit to only display the controllers of that state. You can select more than one state with SHIFT-click. The All button sets all the bits so that you can see all the controllers of the object. The Ini button sets the state mask back to the object default state. You can change the default state of object by first selecting the desired state mask and storing using the menu under the State button. If you define a default state mask, it will be loaded into the object state make when you load the blend file or when you run the game under the blenderplayer. However, when you run the game under Blender, the current selected state mask will be used as the startup state for the object. This allows you to test specific state during the game design. The controller display the state they belong to with a new button in the controller header. When you add a new controller, it is added by default in the lowest enabled state. You can change the controller state by clicking on the button and selecting another state. If more than one state is enabled in the object state mask, controllers are grouped by state for more readibility. The new Sta button in the sensor and actuator column header allows you to display only the sensors and actuators that are linked to visible controllers. A new state actuator is available to modify the state during the game. It defines a bit mask and the operation to apply on the current object state mask: Cpy: the bit mask is copied to the object state mask. Add: the bits that set in the bit mask will be turned on in the object state mask. Sub: the bits that set in the bit mask will be turned off in the object state mask. Inv: the bits that set in the bit mask will be inverted in the objecyy state mask. Notes ===== - Although states have no name, a simply convention consists in using the name of the first controller of the state as the state name. The GUI will support that convention by displaying as a hint the name of the first controller of the state when you move the mouse over a state bit of the object state mask or of the state actuator bit mask. - Each object has a state mask and each object can have a state engine but if several objects are part of a logical group, it is recommended to put the state engine only in the main object and to link the controllers of that object to the sensors and actuators of the different objects. - When loading an old blend file, the state mask of all objects and controllers are initialized to 1 so that all the controllers belong to this single state. This ensures backward compatibility with existing game. - When the state actuator is activated at the same time as other actuators, these actuators are guaranteed to execute before being eventually disabled due to the state change. This is useful for example to send a message or update a property at the time of changing the state. - Sensors that depend on underlying resource won't reset fully when they are isolated. By the time they are acticated again, they will behave as follow: * keyboard sensor: keys already pressed won't be detected. The keyboard sensor is only sensitive to new key press. * collision sensor: objects already colliding won't be detected. Only new collisions are detected. * near and radar sensor: same as collision sensor.
2008-06-18BGE Patch: Add Shape Action support and update MSCV_7 project file for glew.Benoit Bolsee
Shape Action are now supported in the BGE. A new type of actuator "Shape Action" is available on mesh objects. It can be combined with Action actuator on parent armature. Only relative keys are supported. All the usual action options are available: type, blending, priority, Python API. Only actions with shape channels should be specified of course, otherwise the actuator has no effect. Shape action will still work after a mesh replacement provided that the new mesh has compatible shape keys.
2008-04-30fix BGE bug #8869: Added objects are not lit correctlyBenoit Bolsee
The current layer information is now stored in KX_GameObject and inherited from the parent object when dynamically added. This information is used during the rendering the select the lamps. As the selected lamps are always coming from active layers, their position and orientation are correct.

2008-03-24Commit patch #8724:Benoit Bolsee
This patch modifies the BL_ConvertMesh method from the data conversion module in order to reduce the number of polygon material objects that are created. Normally, there should be only one material object for each material bucket(the group of meshes that are rendered together with a single material). However, the number of materials that are created right now in the converter is much higher and eats a lot of memory in scenes with large polygon counts. This patch deletes those material objects(KX_BlenderMaterial) that are used only temporarily in the converter(and are now deleted only when the converter is destroyed, at the end of the game). For a cube that's subdivided 7 times(90+ k polygons) I get 200 MB usage in the game engine in 2.45 and 44 MB with a svn build with this patch applied if the "Use Blender Materials" option is activated in the Game menu.
2008-03-22Correction on BGE fixes:Benoit Bolsee
- check that an object has been created before setting the physics environment - check that there is an active camera before using it - when a camera is deleted, remove it from m_cameras list
2008-03-10BGE fix: game object to controller links consistancy maintained regardless ↵Benoit Bolsee
of order of deletion AddObject actuator forces last created object to hang in memory even after object is removed from scene => bad link between object and physic controller that causes Blender to crash in case a python script tries to use it (bad programming anyway). This patch avoids the crash by maintaining consistent links at all time.

2005-04-18Patch: [ #2439 ] Makes objects react properly to deformations after a mesh ↵Kester Maddock
replacement call. from brian hayward (bthayward) Detailed description: Currently, when an armature deformed object's mesh is replaced by the ReplaceMesh actuator, the new mesh fails to deform to the armature's movement. My patch fixes this by properly replacing the deform controller along with the mesh (when appropriete). For instance, if one had an animated character using any of the standard deformation techniques (armature, ipo, RVK, or AVK), that character's mesh would currently be prevented from changing mid-game. It could be replaced, but the new mesh would lack the controller which tells it how to deform. If one wanted to dynamiclly add a hat on top of the character's head, it would require storing a secondary prebuilt character (mesh, armature, logic, ect...) on another layer FOR EACH HAT the character could possibly wear, then swapping out the whole character when the hat change was desired. So if you had 4 possible hat/character combos, you would have 4 character meshes, 4 armatures, 4 sets of logic, and so on. I find this lack of flexibility to be unresonable. With my patch, one could accomplish the same thing mearly by making one version of the character in the main layer, and adding an invisible object atop the character's head (which is parented to the head bone). Then whenever it becomes desirable, one can replace the invisible object's mesh with the desirable hat's mesh, then make it visible. With my patch, the hat object would then continue to deform to the character's head regardless of which hat was currently being worn. *note 1* for armature/mesh deformations, the new mesh must have properly assigned vertex groups which match one or more of the bones of the target armature before the replaceMesh call is made. Otherwise the vertices won't react to the armature because they won't know how. (not sure if vertices can be scripted to change groups after the game has started) *note 2* The added processing time involved with replacing the object's deform controller is negligible.
