2.49 BGE Todos

Major Bugs

These bugs show features that have broken since 2.48a and need to be addressed:

• IPOs no longer work on Dynamic objects
• Constraints no longer work on softbodies
• Modifiers now crash the game engine
• Changing lights in real-time does not work with GLSL materials

Api Todo

These are things that need to be finished for the BGE api:

• Find and address all KX_PYATTRIBUTE_TODO's (these can be grep'ed)
• Clean up the object (motion) actuator
