When the mesh field is left blank and Physics option is enabled, it reinstances the physics mesh from the existing mesh.
like calling gameOb.reinstancePhysicsMesh() from python.
Add support back for reinstancePhysics mesh, a frequently requested feature in the BGE forums.
from what I can tell Sumo supported this but bullet never did.
Currently only accessible via python at the moment.
- rigid body, dynamic, static types work.
- instanced physics meshes are modified too.
- compound shapes are not supported.
Physics mesh can be re-instanced from...
* shape keys & armature deformations
* subsurf (any other modifiers too)
* RAS_TexVert's (can be modified from python)
Moved the reinstancePhysicsMesh functions from RAS_MeshObject into KX_GameObject since the physics data is stored here.

* ensure all SConscripts are ready for win64-vc (where necessary).
* ensure we have proper _DEBUG flag for Python when we're doing a debug build.
* some cleaning up of linking etc.
* ensure /EHsc is there for game engine modules.
Mathutils support for subclassing Vector, Quat, Euler and Matrix types.
Removed C docstrings, prefer to make sure our epydocs are well maintained rather then duplicate, vague doc strings.
Will convert scripts to detect missing docs from the BGE.
Adding a UI to set the type on startup can be added easily.
# ----
class myPlayer(GameTypes.KX_GameObject):
def die(self):
# ... do stuff ...
self.endObject()
# make an instance
player = myPlayer(gameOb) # gameOb is made invalid now.
player.die()
# ----
One limitation (which could also be an advantage), is making the subclass instance will return that subclass everywhere, you cant have 2 different subclasses of the same BGE data at once.
Remove the last of the odd C++/python wrapper code from http://www.python.org/doc/PyCPP.html (~1998)
* Use python subclasses rather then having fake subclassing through get/set attributes calling parent types.
* PyObject getset arrays are created while initializing the types, converted from our own attribute arrays. This way python deals with subclasses and we dont have to define getattro or setattro functions for each type.
* GameObjects and Scenes no longer have attribute access to properties. only dictionary style access - ob['prop']
* remove each class's get/set/dir functions.
* remove isA() methods, can use PyObject_TypeCheck() in C and issubclass() in python.
* remove Parents[] array for each C++ class, was only used for isA() and wasnt correct in quite a few cases.
* remove PyTypeObject that was being passed as the last argument to each class (the parent classes too).
TODO -
* Light and VertexProxy need to be converted to using attributes.
* memory for getset arrays is never freed, not that bad since its will only allocates once.
* all mathutils types now have optional callbacks
* PyRNA returns mathutils quat and euler types automatically when they have the rotation subtype.
* PyRNA, reuse the BPy_StructRNA PyObject rather name making a new one for each function returned.
* use more arithb.c functions for Mathutils quaternion type (less inline cruft).
* BGE Mathutils integration mostly finished- KX_PyMath now converts to Mathutils types rather then lists.
* make all mathutils types share the same header so they can share a number of functions - dealloc, getWrapped, getOwner.
Any 3x3 or 4x4 rna matrix will automatically be returned as a Mathutils matrix.
This makes useful stuff like multiplying a vector location by an object matrix possible.
ob = bpy.data.scenes[0].objects[0]
print (ob.data.verts[0].co * ob.matrix)
Also added mathutils matrix types to the BGE GameObject.localOrientation, worldOrientation
* MT_Matrix3x3 added getValue3x3 and setValue3x3, assumed a 4x3 float array.
* KX_GameObject.cpp convenience functions NodeSetGlobalOrientation, NodeGetLocalOrientation, NodeGetLocalScaling, NodeGetLocalPosition.
* 2.5 python api now initializes modules BGL, Mathutils and Geometry
* modules py3 PyModuleDef's use PyModuleDef_HEAD_INIT, rather then {}, was making msvc fail to build.
* added macros for Vector_ReadCallback, Vector_WriteCallback etc. to check if the callback pointer is set before calling the function.
in short, vectors can work as if they are thin wrapped but not crash blender if the original data is removed.
* RNA vector's return Mathutils vector types.
* BGE vectors for GameObject's localPosition, worldPosition, localPosition, localScale, worldScale, localInertia.
* Comment USE_MATHUTILS define to disable returning vectors.
Example...
* 2.49... *
loc = gameOb.worldPosition
loc[1] = 0
gameOb.worldPosition = loc
* With vectors... *
gameOb.worldPosition[1] = 0
* But this wont crash... *
loc = gameOb.worldPosition
gameOb.endObject()
loc[1] = 0 # will raise an error that the objects removed.
This breaks games which assume return values are lists.
Will add this to eulers, matrix and quaternion types later.
* removed radiosity render code, DNA and RNA (left in radio render pass options), we'll get GI to replace this probably, better allow baking to vertex colors for people who used this.
* removed deprecated solid physics library, sumo integrations and qhull, a dependency
* removed ODE, was no longer being build or supported
* remove BEOS and AMIGA defines and references in Makefiles.
* Update cmake and makefiles to link python generic.
* Fix game engine building for cmake and makefiles.
* Fix compile error with py 3.x, due to 2.x compat fix.
* Mathutils, Geometry, BGL, Mostly working, some //XXX comments for things to fix with py3
python import override (bpy_internal_import.c) so you can import python internal scripts from the BGE and running blender normally.
De-activating a loop-end actuator didnt work (it kept looping).
Looked into this further and it turns out that the actuators run with both positive and negative events false, the sound actuator assumes because its not negative that its a positive event and plays the sound anyway.
Fix by checking that its a positive event before playing.
The size limit on the message actuator was 100 which broke some scripts, set to 16384 instead.
* Removed modules Expression and CValue, neither were ever available.
* Added GameLogic.EvalExpression(exp) from the Expression module, evaluates an expression like the expression controller (not sure if this is really that useful since python is far more advanced).
* resetting the original blend file path didint work (own fault == -> =)
* Py3.x PyModule_Create didnt allow importing since it didn't add to sys.modules,
Looks like they want us to use init-tab array, but this doesn't suit us since
it needs to be setup before python is initialized.
* Documented GameLogic.globalDict
* pressing P starts the BGE in the 3D view
* redraw window clipping isnt right
* BGE python api works in py3k (without __import__ override or Mathutils, BGL, Geometry)
* no events yet (so there is no way to exit)
* Missing changes to release/windows/installer
* Sequencer fixes in source/blender/src/seqaudio.c dont apply to 2.5
* brechts fix for #18855 r20763 wasnt merged, does this apply to 2.5?
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
- fix for [#18867] getScreenRay error
... the Vector wasn't been added to KX_Camera origin. Therefore the Ray was always casted to the wrong coordinate when camera wasn't in [0,0,0] (where is obviously was in my tests :)
- making the input parameter compatible with Blender/BGE window coordinate system (Top-Bottom).
... that will break scripts done in 2.49. Since this feature was added only in 2.49 that fix is OK. (and the fix is ridiculous.
Note:
the input parameter is normalized. That means it runs from 0.0 to 1.0. Some users found it confusing, but it allows to make a game compatible with multiple desktop resolutions.a
- CValue warning ShowDeprecationWarning("val = ob.attr", "val = ob['attr']"); had false positives because of python using getattr() internally. Only show the wanring now when a CValue is found.
- Py functions that accepted a vector and a GameObject were slowed down by PySequence_Check() first called on the GameObject, though this would fail it would try and get attributes from the game object - ending up in ~8 attribute lookups each time. Avoiding PySequence_Check() makes ob.getDistanceTo(otherOb) over twice as fast.
- Joystick hat events could crash the BGE for joysticks with more then 4 hats.
- PLY Import failed on PLY files from Carve, added some extra types.
the original blendfile path wasn't reset when loading new blendfiles.
blenderplayer was ok, but running the BGE from blender would set the blendfile original path and never reset it on loading other blend files.
