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.

vertex pinning/constraint attach to other objects.
|
|
fake world coordinate system to game soft bodies, although the vertices are already in world space.
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)
|
|
set a fake world transform for game soft bodies, based on center of the AABB, so visiblity and some game logic works. note: this world transform is not smooth.
|
|
copy normals for soft body vertices, to get proper lighting
|
|
use shape matching by default for game soft bodies
store soft body index for game vertices
|
|
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:

The Physics button controls the creation of a physics representation
of the object when starting the game. If the button is not selected,
the object is a pure graphical object with no physics representation
and all the other physics buttons are hidden.
Selecting this button gives access to the usual physics buttons.
The physics button is enabled by default to match previous Blender
behavior.
The margin parameter allows to control the collision margin from
the UI. Previously, this parameter was only accessible through
Python. By default, the collision margin is set to 0.0 on static
objects and 0.06 on dynamic objects.
To maintain compatibility with older games, the collision margin
is set to 0.06 on all objects when loading older blend file.
Note about the collision algorithms in Bullet 2.71
--------------------------------------------------
Bullet 2.71 handles the collision margin differently than Bullet 2.53
(the previous Bullet version in Blender). The collision margin is
now kept "inside" the object for box, sphere and cylinder bound
shapes. This means that two objects bound to any of these shape will
come in close contact when colliding.
The static mesh, convex hull and cone shapes still have their
collision margin "outside" the object, which leaves a space of 1
or 2 times the collision margin between objects.
The situation with Bullet 2.53 was more complicated, generally
leading to more space between objects, except for box-box collisions.
This means that running a old game under Bullet 2.71 may cause
visual problems, especially if the objects are small. You can fix
these problems by changing some visual aspect of the objects:
center, shape, size, position of children, etc.

account parent inverse node. Fix scaling bug on instantiation of compound shape: child shape didn't have correct shape. Note: global scaling doesn't work on compound shape (limitation of Bullet); don't set any scale on the top dynamic object.

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.

the object is applied. The scale is now applied to the shape before the creation of the rigid body.

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.

out the #define WAIT_FOR_VSYNC 1
- GEdon't crash when attempting to add constraint on game objects without physics controller
- GEimproved some physics -> graphics synchronization issues
- small experiment with game engine timing to smooth framerate/reduce tearing

All platforms/build systems: either upgrade to use extern/bullet2, or disable the game engine until the build is fixed.

are different from Bullet rigidbody constraints like the hinge, and point 2 point!)
- fixed a crashing bug related to objects without meshes (tried to get material info from it)
|
|
Done using a special hinge constraint (no translational degrees of freedom removed)
|
|
- broadphase had bugs in removing objects,
- persistent manifold renamed value,
- cylinder penetration depth fixed,
- memory leak for persistent manifold

(disabled).
Requires some changes to projectfiles/makefiles/scons, for the added and removed files!
|

extern/bullet/BulletDynamics/ConstraintSolver/SimpleConstraintSolver.h
added newline at end of file.
intern/boolop/intern/BOP_Face2Face.cpp
fixed indentation and had nested declarations of a varible i used
for multiple for loops, changed it to just one declaration.
source/blender/blenkernel/bad_level_call_stubs/stubs.c
added prototypes and a couple other fixes.
source/blender/include/BDR_drawobject.h
source/blender/include/BSE_node.h
source/blender/include/butspace.h
source/blender/render/extern/include/RE_shader_ext.h
added struct definitions
source/blender/src/editmesh_mods.c
source/gameengine/Ketsji/KX_BlenderMaterial.cpp
source/gameengine/Ketsji/KX_ConvertPhysicsObjects.cpp
source/gameengine/Ketsji/KX_RaySensor.cpp
removed unused variables;
source/gameengine/GameLogic/Joystick/SCA_Joystick.cpp
changed format of case statements to avoid warnings in gcc.

Added newlines at end of a bunch of files that didn't have them.
removed a couple of unused variables and an extra ';'
(Also removed config.h crap from these files)

For the baked dominos. Thanks to Tom M (LetterRip) for the blend.

tweaker, friction/restitution, more scaling related fixes.
|
|
add/remove object support, bounding volume hierarchy). Added a few files, updated the Bullet scons. Vc6/7 Bullet projectfiles need to add a couple of files: 'Bullet/CollisionShapes/BvhTriangleMeshShape.cpp',
'Bullet/CollisionShapes/ConvexTriangleCallback.cpp',
'Bullet/CollisionShapes/EmptyShape.cpp',
'Bullet/CollisionShapes/OptimizedBvh.cpp',
'Bullet/CollisionShapes/TriangleCallback.cpp',
'Bullet/CollisionShapes/TriangleIndexVertexArray.cpp',
'Bullet/NarrowPhaseCollision/ManifoldContactAddResult.cpp'.
Sorry, no armatures fix yet.

including implementation. hope it works, and doesn't break to much.
it bakes physics objects transform into ipo, every frame of the running gameengine.
When you disable and run the game again, it clears the ipo's again. just for physics objects at the moment.
(perhaps some better UI in the future?)

added raycast support for bullet (no triangle-mesh support, soon)
added python methods for 'getHitObject', getRayDirection, getHitPosition and getHitNormal for mouse over sensor,
which makes it easy for a shootout.blend demo :)
|
|
fixed some copy/paste bug in inertia/inverse inertia.
colors in deactivation debug
|
|
tweaked friction, some more preparations but no real functionality added yet
