370850146f BGE patch #18051: add localInertia attribute to GameObject. 2009-04-08 16:25:00 +00:00

509ca83ef1 BGE patch 18065: gameobj mass writeable + setmass actuator. This patch allows to change the mass of a dynamic or rigid body object during the game. Two methods are available: in a Python script by setting the mass attribute of the game object; by logic brick with the Edit Object->Dynamics->Set Mass actuator. The mass can only be set on dynamic objects and must be a positive floating point value. 2009-01-14 22:33:39 +00:00

949b6ca80f BGE bug #17688 fixed: Near Sensor Reset not working (for Gamekit)
Implementation of the PHY_IPhysicsController::SetMargin(),
GetMargin(), SetRadius() and GetRadius() for Bullet and Sumo
to allow resetting the Near sensor radius. For bullet use 
the new setUnscaledRadius() function to change sphere radius.

In pPreparation of a Fh constraint actuator:
- Add KX_IPhysicsController::GetRadius()
- Fix implementation of KX_BulletPhysicsController::GetVelocity()
  (velocity at a point in geometric coordinate)
- Don't try to set velocity on static object (Bullet will assert)
- Add KX_GameObject::GetVelocity() for C access to local velocity

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.

a397b4b82f BGE bug fix (good for 2.47): SetParent actuator did not work on dynamic objects. Dynamics will now be disabled automatically and the object will be set ghost for the duration of the parenting; this is to avoid static interaction with the parent object. The dynamic state is restored when the parenting is removed with RemoveParent actuator. This fix also applies to setParent() and removeParent() python functions. 2008-07-18 14:40:24 +00:00

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.

411123b250 - added debug line drawing in gameengine (handy for debugging physics problems)
- added #ifdef for a visual studio 8 crashing problems
- added scaling and tolerances to triangle meshes

38b993f787 Speed up the physics engine: hook the SOLID broad phase, so we can either reject the test or request the penetration depth test as necessary. Previously we were doing the penetration depth test, as well as SOLID's intersection test. 2004-11-06 04:58:10 +00:00

3dd18c5c34 Added an UpdateTransform callback from SceneGraph -> Physics.
Profiling revealed that the SceneGraph updated every physics object, whether it moved or not, even though the physics object was at the right place.  This would cause SOLID to go and update its bounding boxes, overlap tests etc.
This callback handles the special case (parented objects) where the physics scene needs to be informed of changes to the scenegraph.

Added Python attributes (mass, parent, visible, position, orientation, scaling) to the KX_GameObject module.
Make KX_GameObject use the KX_PyMath Python <-> Moto conversion.

5398f1ba77 Added resolveCombinedVelocities()
Fixed drot actuator.  The rotation matrix was being mutilated by passing a float[9] instead of float[12].

00291b5cf4 [GameEngine] Commit all Kester's changes made to the gameengine to restore 2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them

That was about it.

There are a few things that needs double checking:

* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.

2d5514be28 Brought back the sumo physics controllers and undid game engine make file
changes.
Instead modified the top level nan_definitions.mk to point the NAN_SUMO and
NAN_FUZZICS to the right locations.
