Dev:Ref/Release Notes/2.49/2.49b/Game Engine

Python API

Python API Bugfixes 2.49b

• Converting a mesh from a python argument was broken but happened to work in some cases.
• Memory leak fix for action.channelNames.
• Was writing to freed memory when freeing a python object in some cases.
• Removing GameLogic.EvalExpression(), was unstable.
• Crash fix when casting a ray to the same location as the object.
• Fixed KX_PolyProxy returning improper VertexIndex with mixed triangles and quads with using .getVertexIndex() and .v1, .v2, etc. [bug #19254]
• Fixed obj.sendMessage() with 4 arguments crashing blender [bug #18963]

Python API Bugfixes 2.49a

• Camera functions getScreenPosition, Ray and Vect fixes
• Bug in KX_GameObject.get() and ListValue.get() returning python types float/int/string.
• Pythons sys.path creation was broken in windows (caused YoFrankie game to not start)
• Action Actuator setChannel() function was broken in a number of ways.
• Deprecation warnings were printed twice.

Python API Improvements 2.49a

• GE Python support for __contains__ "prop" in gameOb and "OBCube" in scene.objects syntax.
• GE Python support for dictionary style get() cont.actuators.get("key", default), works for sensors and object controllers too.
• Action actuator getChannel("name") function to get the bone loc,size,quat for a bone.

Physics

Improvements 2.49b

• Game Engine Physics support for reinstancePhysics mesh from Python and the dynamic actuator.
  • ReplaceMesh Actuator option to replace the physics mesh and display mesh + python api options.
  • Video: http://www.graphicall.org/ftp/ideasman42/reinstance.ogv
  • Blend demo file: http://www.graphicall.org/ftp/ideasman42/reinstance_demo.blend
• Mouse focus sensor "pulse" option to pulse TRUE when the object under the mouse changes.

Bullet Bugfixes 2.49b

• Crash fix when a parent compound object didn't have a physics controller.
• Fix for the torque actuator x -& y-axis not working.

Bullet Bugfixes 2.49a

• Fix for Torque and 6DOF constraints
• Applied torque breaks rigid bodies in game engine

Bug Fixes

Game Engine Bugfixes 2.49b

• Saving runtime on Windows didn't work with python2.6
• Let IPO's animate the ref value for KX_BlenderMaterial's

Game Engine Bugfixes 2.49a

• Anisotropic friction with zero values caused objecs to jump to infinity
• Materials using Object texture coordinates caused crash
• light in skinned object only work properly after running the action once.
• Avoid crashing BGE on Mobile Intel GMA 950/945 Express GPU
• Lights in non-glsl mode didn't move anymore, missing matrix update.
• Changing the scale of a sleeping object wasn't working with bullet.
• Dynamically added sensor objects didn't have their physic shape synchronized with movement.
• Loading older blend files (from the blender Gamekit 1.0 demos) that use Sumo crashed on playback
• Shadow face flag ignored object's scale.
• Sound Actuator negative events would play a sound when no sound had played yet.
• Sound Actuator with loop-end stop on negative events.
