Surprising this wasn't noticed before. Any mix of quads/tris caused the face verts of either quads/tries (whichever comes last).
Tested by exporting the KX_MeshProxy and re-importing as an OBJ.
This fix assumes there are only 2 m_darray's per face array which is currently true, but wont be if edge support is added back.
Previously the only way to detect if the mouse moved over a different object was to enable true-level-triggering and have a python script detect the change.
When the Pulse option is set, focusing on a different object pulses true.
Python attribute is focusSensor.usePulseFocus.
This is similar to the collision sensors pulse option where changes in the set of collision objects generates an event too.
Found this functionality missing when trying to make a logic demo that used mouse-over with overlapping objects.
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.

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
- 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.
GameEngine sys.path creation was broken because of a pesky slash at the end of each path name.
Win32 sys.paths were also failing when running a game that switched between blend files in different directories
On win32 for some reason making absolute paths from lib->name failed, work around this by using lib->filename.
STR_String.h, cast to float to quiet compiler warnings.
so where foo is an int prop,
gameOb.get("foo") == 0, would end up returning a CValue int proxy.
This is more a problem for KX_GameObject since ListValues with python access mostly don't contain ints, strings, floats.
This also wont break games from 2.48 since the .get() function wasn't available.
importing "pygame" failed when running the BGE for the second time.
Rather then clearing modules, backup and restore them (as its doing with sys.path)
This way the BGE will never remember any modules imported during game play (which can cause bugs/crashes), but it also wont break pythons state by possibly removing modules that are being used internally.
- Deprecation warnings for using attribute access
- Added dictionary functions to KX_GameObject and ListValue
ob.get(key, default=None)
ob.has_key(key)
ob.has_key is important since there was no way to do something like hasattr(ob, "attr") which can be replaced by ob.has_key("attr") - (both still work of course).
ob.get is just useful in many cases where you want a property if it exists but can fallback to a default.
- CListValue::FindValue was adding a reference but the ~3 places it was used were releasing the reference. added a FindValue that accepts a const char* type to avoid converting python strings to STR_String.
- Removed/Commented some unused vars
- CValue::GetPropertyText() could return a temp reference to a variable on the stack, option wasnt used anywhere so removed.
- KX_ConstraintWrapper::GetConstraintId allows args but ignored them
- KX_ConstraintWrapper::PySetParam didnt return NULL on an error (messing up pythons exceptions).
- BLI_natstrcmp didnt return 0 when the while loop exited
For this actuator to be useful it needs to use the first opened blendfile as the base name for the configuration file.
A recent fix that made the gp_GamePythonPath always match the current loaded blend file made this actuator work differently.
keep the original filename to use for making the config name so you can load the config between loading blendfiles.
- Typo in occlusion variable init "m_buffer == NULL;" -> "m_buffer = NULL;"
CcdPhysicsEnvironment.cpp and CcdPhysicsController.cpp had too many warnings, fixed most of them.
+ fixed Python method, PyArg_ParseTuple already checks for errors, no returning of NULL, thanks Campbell too)
+ added linear/angular spring for each of the 6DOFs of a generic 6dof constraint. This makes the generic 6dof constraint very versatile.
allow to dynamically create rigid body constraints while disable collision detection between connected bodies, pass as 10th argument the flag 128
PhysiPython KX_ConstraintWrapper, setParam
export setParam(paramIndex,paramValue0,paramValue1) for Physics constraints
paramIndex 0,1,2 are linear limits, 3,4,5 are angular limits, 6,7,8 are linear motors, 9,10,11 are angular motors
For example:
disableConnectedBodies=128
cons = PhysicsConstraints.createConstraint(oid,rid,generic6dof,pivotInAx,pivotInAy,pivotInAz,angleX,angleY,angleZ,disableConnectedBodies)
#params 0,1,2 are linear limits, low,high value. if low > high then disable limit
cons.setParam(0,0,0)
I will provide an example .blend for Blender 2.49

(todo: expose this setting in World setting GUI)
Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.
SCA_RandomActuator: The random generator was shared between replicas and not deleted. Added ref counting between replicas to allow deletion at the end.
KX_Camera: The scenegraph node was not deleted for temporary cameras (ImageMirror and shadow), causing 500 bytes leak per frame and per shadow light.
KX_GameActuator: Global dictionary buffer was not deleted after saving.
KX_MotionState: The motion state for compound child was not deleted
KX_ReplaceMeshActuator: The mesh was unnecessarily converted for each actuator and not deleted, causing large memleak.
After these fix, YoFrankie runs without memleak.
