Was annoying to use a different editor for cmake only.
theeth says this should be ok with gsoc and merges from branches.

* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
|
|
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.
|
|
* first working changes to get blenderplayer linking
* blenderplayer/ moved into source/ (CMakeLists.txt changed for that too)
* added externs for bprogname to gp_ghost, so that it links properly
|
|
* Add BGE_CXXFLAGS so we can get rid of hard-coded BGE compiler settings. This was only done for windows, but now linuxers and osxers should be able to set BGE-specific optimisation too. See the windows default configs for example.

python api options.
When the mesh field is left blank and Physics option is enabled, it reinstances the physics mesh from the existing mesh.
like calling gameOb.reinstancePhysicsMesh() from python.

* ensure all SConscripts are ready for win64-vc (where necessary).
* ensure we have proper _DEBUG flag for Python when we're doing a debug build.
* some cleaning up of linking etc.
* ensure /EHsc is there for game engine modules.

define extra functions on gameObjects.
Adding a UI to set the type on startup can be added easily.
# ----
class myPlayer(GameTypes.KX_GameObject):
def die(self):
# ... do stuff ...
self.endObject()
# make an instance
player = myPlayer(gameOb) # gameOb is made invalid now.
player.die()
# ----
One limitation (which could also be an advantage), is making the subclass instance will return that subclass everywhere, you cant have 2 different subclasses of the same BGE data at once.

Remove the last of the odd C++/python wrapper code from http://www.python.org/doc/PyCPP.html (~1998)
* Use python subclasses rather then having fake subclassing through get/set attributes calling parent types.
* PyObject getset arrays are created while initializing the types, converted from our own attribute arrays. This way python deals with subclasses and we dont have to define getattro or setattro functions for each type.
* GameObjects and Scenes no longer have attribute access to properties. only dictionary style access - ob['prop']
* remove each class's get/set/dir functions.
* remove isA() methods, can use PyObject_TypeCheck() in C and issubclass() in python.
* remove Parents[] array for each C++ class, was only used for isA() and wasnt correct in quite a few cases.
* remove PyTypeObject that was being passed as the last argument to each class (the parent classes too).
TODO -
* Light and VertexProxy need to be converted to using attributes.
* memory for getset arrays is never freed, not that bad since its will only allocates once.

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.

- script template use new property syntax
- Python could set the axis/hat to a negative index and crash blender (nobody complained)
- Servo control UI had overlapping text
|
|
- CValue warning ShowDeprecationWarning("val = ob.attr", "val = ob['attr']"); had false positives because of python using getattr() internally. Only show the wanring now when a CValue is found.
- Py functions that accepted a vector and a GameObject were slowed down by PySequence_Check() first called on the GameObject, though this would fail it would try and get attributes from the game object - ending up in ~8 attribute lookups each time. Avoiding PySequence_Check() makes ob.getDistanceTo(otherOb) over twice as fast.
- Joystick hat events could crash the BGE for joysticks with more then 4 hats.
- PLY Import failed on PLY files from Carve, added some extra types.

in the UI. When running the game, seed 0 is replaced by a random seed accessible through Python in seed attribute of the actuator. Other seed value will be left unchanged and will generate fixed pseudo random series.

warnings mistook the blender binary for a script - argv[0], Binary lines were printed into the console sometimes causing console beeps and corrupting future console output.
Internal texts file on disk is not used it seems python warnings dont support this (even though exceptions do).
The most common cause of this is passing a float as an argument to a method that took an int.
get around this by setting __file__ in the namespace to the script name before executing the script, the file lines are not found but at least the output is not weird and confusing.
Added read only 'mode' attribute to the python controller so there is a way to tell if its executing a module or a script. Updated docs to better explain execution methods.

if(SDL_PollEvent(&sdl_event)) // if -> while fixed it
removed 'm_buttonnum' was misleading, wasn't used as you expect.
Added gravity to variable to world to be used by collada.

bug reported by blenderage on blenderartist (found other bugs too).
- "All Hat Events" didnt work.
- Multiple hats didnt work
- use a menu with direction names rather then have the user guess. disallow zero as a direction.
- Allow up to 4 hats (was 2).
- Python api was clamping the axis to 2, maximum is currently JOYAXIS_MAX - 16
- New python attributes hatValues and hatSingle, match axis functions.
- Use SDL Axis events to fill in the axis and hat array rather then filling in every axis with SDL_JoystickGetAxis for each axis event.

SCA_RandomActuator: The random generator was shared between replicas and not deleted. Added ref counting between replicas to allow deletion at the end.
KX_Camera: The scenegraph node was not deleted for temporary cameras (ImageMirror and shadow), causing 500 bytes leak per frame and per shadow light.
KX_GameActuator: Global dictionary buffer was not deleted after saving.
KX_MotionState: The motion state for compound child was not deleted
KX_ReplaceMeshActuator: The mesh was unnecessarily converted for each actuator and not deleted, causing large memleak.
After these fix, YoFrankie runs without memleak.

was a module (could be a class).

submodules.
Now reload all the submodules too.
It was also hiding the error message if there was a syntax error which wasnt so helpful.
|
|
Previous patch was not sorting the state actuators. This was causing
some problems with YoFrankie that relies on the order of actuators
when multiple state actuators are activated at once.
Active state actuators will now be sorted per object. This doesn't
change the fact that state actuators are executed before all other
actuators as before.
Incidently, made the logic loop faster.
|
|
use PY_SET_ATTR_FAIL and PY_SET_ATTR_SUCCESS return values so the fake subclassing can know if a value failed to be set or if it was missing from the type. (with PY_SET_ATTR_MISSING)
Also noticed some other mistakes.
- KX_LightObject, setting the type didnt check for an int.
- KX_SoundActuator, didnt return an error when assigning an invalid orientation value
- KX_GameObject, worldOrientation didnt return an error value.

controllers.
A new bookmark button is available on the controller UI.
When set, the controller is guaranteed to execute before all
other non-bookmarked controllers, provided it is scheduled
for execution.
This is useful for initialization scripts that run once at startup or
scripts that must set some prerequisite for the other controllers at
the start of each logic frame.
This feature is also available at python level with the "bookmark"
attribute. It can be changed during the game.
Note that if several script are bookmarked, their relative order of
execution is not guaranteed. Make sure they don't depend on each other.
|
|
- corrections to docs
- disallow calling controller.activate(actuator) when the controller is not active. (Raise a SystemError)
- Added 2 new attributes, CValue.name - deprecates CValue.getName(), KX_GameObject.children deprecated KX_GameObject.getChildren(), (same for getChildrenRecursive()).

collision capbility.
A new type of "Sensor" physics object is available in the GE for advanced
collision management. It's called Sensor for its similarities with the
physics objects that underlie the Near and Radar sensors.
Like the Near and Radar object it is:
- static and ghost
- invisible by default
- always active to ensure correct collision detection
- capable of detecting both static and dynamic objects
- ignoring collision with their parent
- capable of broadphase filtering based on:
* Actor option: the collisioning object must have the Actor flag set to be detected
* property/material: as specified in the collision sensors attached to it
Broadphase filtering is important for performance reason: the collision points
will be computed only for the objects that pass the broahphase filter.
- automatically removed from the simulation when no collision sensor is active on it
Unlike the Near and Radar object it can:
- take any shape, including triangle mesh
- be made visible for debugging (just use the Visible actuator)
- have multiple collision sensors using it
Other than that, the sensor objects are ordinary objects. You can move them
freely or parent them. When parented to a dynamic object, they can provide
advanced collision control to this object.
The type of collision capability depends on the shape:
- box, sphere, cylinder, cone, convex hull provide volume detection.
- triangle mesh provides surface detection but you can give some volume
to the suface by increasing the margin in the Advanced Settings panel.
The margin applies on both sides of the surface.
Performance tip:
- Sensor objects perform better than Near and Radar: they do less synchronizations
because of the Scenegraph optimizations and they can have multiple collision sensors
on them (with different property filtering for example).
- Always prefer simple shape (box, sphere) to complex shape whenever possible.
- Always use broadphase filtering (avoid collision sensor with empty propery/material)
- Use collision sensor only when you need them. When no collision sensor is active
on the sensor object, it is removed from the simulation and consume no CPU.
Known limitations:
- When running Blender in debug mode, you will see one warning line of the console:
"warning btCollisionDispatcher::needsCollision: static-static collision!"
In release mode this message is not printed.
- Collision margin has no effect on sphere, cone and cylinder shape.
Other performance improvements:
- Remove unnecessary interpolation for Near and Radar objects and by extension
sensor objects.
- Use direct matrix copy instead of quaternion to synchronize orientation.
Other bug fix:
- Fix Near/Radar position error on newly activated objects. This was causing
several detection problems in YoFrankie
- Fix margin not passed correctly to gImpact shape.
- Disable force/velocity actions on static objects

games I guess). State actuators will now execute before any other actuators to make sure that the actuators link count are up to date when they execute.

This commit extends the technique of dynamic linked list to the logic
system to eliminate as much as possible temporaries, map lookup or
full scan. The logic engine is now free of memory allocation, which is
an important stability factor.
The overhead of the logic system is reduced by a factor between 3 and 6
depending on the logic setup. This is the speed-up you can expect on
a logic setup using simple bricks. Heavy bricks like python controllers
and ray sensors will still take about the same time to execute so the
speed up will be less important.
The core of the logic engine has been much reworked but the functionality
is still the same except for one thing: the priority system on the
execution of controllers. The exact same remark applies to actuators but
I'll explain for controllers only:
Previously, it was possible, with the "executePriority" attribute to set
a controller to run before any other controllers in the game. Other than
that, the sequential execution of controllers, as defined in Blender was
guaranteed by default.
With the new system, the sequential execution of controllers is still
guaranteed but only within the controllers of one object. the user can
no longer set a controller to run before any other controllers in the
game. The "executePriority" attribute controls the execution of controllers
within one object. The priority is a small number starting from 0 for the
first controller and incrementing for each controller.
If this missing feature is a must, a special method can be implemented
to set a controller to run before all other controllers.
Other improvements:
- Systematic use of reference in parameter passing to avoid unnecessary data copy
- Use pre increment in iterator instead of post increment to avoid temporary allocation
- Use const char* instead of STR_String whenever possible to avoid temporary allocation
- Fix reference counting bugs (memory leak)
- Fix a crash in certain cases of state switching and object deletion
- Minor speed up in property sensor
- Removal of objects during the game is a lot faster

controller.actuators[name] and controller.sensors[name]
Made a read-only sequence type for logic brick sensors and actuators which can access single items or be used like a list or dictionary.
We could use a python dictionary or CValueList but that would be slower to create.
So you can do...
for s in controller.sensors: print s
print controller.sensors["Sensor"]
print controller.sensors[0]
sensors = list(controller.sensors)
This sequence type keeps a reference to the proxy it came from and will raise an error on access if the proxy has been removed.
