4ae4ecd3ce BGE patch: Optimization of bullet adaptation layer - part 1. 
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.

31adad5b4d Fix BGE bug: dynamic-but-not-rigid objects are added as rigid body during the game. 2008-05-01 16:00:59 +00:00

f4cc03b0f1 Better fix for BGE bug #7892: dRot is reversed on dynamic objects. Make sure that graphic, Bullet and Sumo(deprecated) objects rotate the same way. This fix reverses the rotation of non-dynamic objects compared to 2.45: you will need to change the sign of dRot in 2.45 games for them to work correctly in 2.46 2008-04-23 21:48:17 +00:00

b1ef25663a BGE crash when using angV & linV actuator on static objects 
The error was causing by the KINEMATIC flag not set automatically when the linear or angular velocity was set on static objects. Note that these actuators still won't work on static objects: the crash is fixed but not the actuator; linV and angV only work on dynamic objects. Fixing the linV and angV actuators on static object requires a bit more reflexion. For the time being, use dRot and dLoc on static objects.
Cleaned the code a bit: added systematic check on the physic controller presence before taking action.

46234f90ce Removed old Blender/extern/bullet, and upgraded game engine to use Bullet 2.x 
All platforms/build systems: either upgrade to use extern/bullet2, or disable the game engine until the build is fixed.

ab71e2a9b5 -added basic support for GameActuator 'load game', relative paths were broken, just load file into memory and load blend from memory. 
-near sensor support
- python binding for PhysicsConstraints.setNumTimeSubSteps (dividing the physics timestep to tradeoff quality for performance)

93c47e1071 - Added support for kinematic objects (interaction between rigidbodies), deriving linear/angular velocity from previous transform/current transform and deltatime. 
- Made another attempt to migrate from Sumo to Bullet: import of older files automatically switch to Bullet, but you can override it, and save the file in 2.42 version. then it stays Sumo physics.

f51d1ef7d6 - fixed Bullet noResponse/ghost mode 
- added ccd option (future use, very basic and inefficient)

71991cf41e Some rigidbody dynamics fixes (scaling again) to make Happy 2006 domino simulation to work. 
See http://www.continuousphysics.com/ftp/pub/test/index.php?dir=blender/&file=happy_2006_blend.zip
For the baked dominos. Thanks to Tom M (LetterRip) for the blend.

9119b6e8a5 Fixed several bugs: python refcounting related and Bullet related (basic 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.

which makes it easy for a shootout.blend demo :)
