When using states, an action like kick or throw can often switch out before finishing playing the action, and there was no way to play from the start frame the second time round. (even setting the actions current frame through python doesn't work work)
* 2 returning errors without exception set another return None instead of NULL.
* a missing check for parent relation
* BPY matrix length was incorrect in matrix.c, this change could break some scripts, however when a script expects a list of lists for a matrix, the len() function is incorrect and will give an error. This was the only thing stopping apricot game logic running in trunk.
Also added a function for GameObjects - getAxisVect(vec), multiplies the vector be the objects worldspace rotation matrix. Very useful if you want to know what the forward direction is for an object and dont want to use Blender.Mathutils which is tedious and not available in BlenderPlayer yet.
This is also needed for removing any force that existed before suspending dynamics - In the case of franky hanging, resuming dynamics when he fell would apply the velocity he had when grabbing making dropping to the ground work unpredictably.
Also note in pydocs that enable/disable rigidbody physics doesn't work with bullet yet.
* Action FrameProp was checking if the string was true, not that it contained any text.
* Added GameObject.getVisible() since there is already a getVisible
* Added GameObject.getPropertyNames() Needed in apricot so Franky can collect and throw items in the level without having the names defined elsewhere or modifying his game logic which is stored in a separate blend file.
Edited Game engine docs to note that the matrix will need to be transposed if used with Mathutils.Matrix()
Edited "Collision" button since ray-sensor also uses collision.
* OB prefix is needed when specifying the object for the Message Actuator, this is very bad since other object fields in the BGE dont need this prefix - a real fix would need do_versions to keep old files running.
* RotationMatrix was all nans if the rotation vector axis was 0,0,0, Changed so in this case just return a matrix that doesn't rotate anything,
spent some angry hours to find these issues, maybe this will save others the hassle ;)
Add a function GameLogic.expandPath() that works like Blender.sys.expandpath() and is also available in the BlenderPlayer.
Fix the game actuator in the BlenderPlayer to work like in Blender:
- try first to load the .blend from the current working directory
- if not found, try to load from the startup .blend or runtime base directory
This patch consists in new KX_GameObject::SetParent() and KX_GameObject::RemoveParent() functions to create and destroy parent relation during game. These functions are accessible through python and through a new actuator KX_ParentActuator. Function documentation in PyDoc.
The object keeps its orientation, position and scale when it is parented but will further rotate, move and scale with its parent from that point on. When the parent relation is broken, the object keeps the orientation, position and scale it had at that time.
The function has no effect if any of the X/Y/Z scale of the object or its new parent are below Epsilon.
Keyboard sensors can now hook escape key. Ctrl-Break can be used from within blender if you've forgotten an end game actuator.
Fixed a stupid bug preventing some actuators working (like TrackTo).
Certain actuators (Add Object/Replace Mesh/Scene/Track To) used to always require a target, or they would not influence the scene. If the actuator target is always set from Python, this could be annoying.
Better use of booleans for python

Use the farthest vertex as the face position when z sorting faces. (Camera is on -z axis!)
