Previously this only worked with the Blender API.
- bpy_internal_import small C file that Blender scripting and the game engine use.
- Tested with blender, blenderplayer, loading files
- Needed to use a hack to override the Main struct since the game engine doesn't set G.main
- when the sandbox is set, only internal scripts can be imported.
- action attribute wasnt checking for NULL (own fault)
- KX_Scene getCamera wasnt checking for NULL
- CListValue had asserts for not yet implimented functionality, this would close blender. Better to print an error if the user manages to run this functions (I managed to by CListValue.count([1,2,3]))
KX_PolygonMaterial and KX_BlenderMaterial - Added a print function (would raise a python error on printing)
* Crashes *
KX_GameObject SetParent - Disallowed setting a parent to its self, caused a recursion crash.
KX_MeshProxy "materials" attribute was segfaulting because of my recent change - I was wrong, you do need to check material types (no idea why since they are both PyObject * at the base)
KX_VisibilityActuator - Wasn't initialized with PyType_Ready() making it crash on access (own fault)
* Crashes because of missing NULL checks *
KX_PolygonMaterial's "gl_texture" attribute wasnt checking for a valid m_tface
KX_GameObject - added checks for GetPhysicsController()
KX_RayCast::RayTest - didnt check for a valid physics_environment
KX_SceneActuator's getCamera python function wasnt checking if there was a camera.
- made camera use PyAttributeDef's
- removed unneeded duplicate matrix type checks
- fixed own bug (added since 2.48a) that broke a converting 4x4 matrix to a PyObject
- Initialize python types with PyType_Ready, which adds methods to the type dictionary.
- use Pythons get/setattro (uses a python string for the attribute rather then char*). Using basic C strings seems nice but internally python converts them to python strings and discards them for most functions that accept char arrays.
- Method lookups use the PyTypes dictionary (should be faster then Py_FindMethod)
- Renamed __getattr -> py_base_getattro, _getattr -> py_getattro, __repr -> py_base_repr, py_delattro, py_getattro_self etc.
From here is possible to put all the parent classes methods into each python types dictionary to avoid nested lookups (api has 4 levels of lookups in some places), tested this but its not ready yet.
Simple tests for getting a method within a loop show this to be between 0.5 and 3.2x faster then using Py_FindMethod()
Added the method into the PyType so python knows about the methods (its supposed to work this way).
This means in the future the api can use PyType_Ready() to store the methods in the types dictionary.
Python3 removes Py_FindMethod and we should not be using it anyway since its not that efficient.
- Bugfix for running dir() on all BGE python objects. was not getting the immediate methods and attributes for each class.
- Use attributes for KX_Scene (so they are included with dir())
- Override __dict__ attributes for KX_Scene and KX_GameObject so custom properties are included with a dir()
ob.someProp = 10
can now be...
ob["someProp"] = 10
For simple get/set test with an objects 10 properties, this is ~30% faster.
Though I like the attribute access, its slower because it needs to lookup BGE attributes and methods (for parent classes as well as KX_GameObject class).
This could also be an advantage if there are collisions between new attributes added for 2.49 and existing properties a game uses.
Made some other small optimizations,
- Getting and setting property can use const char* as well as STR_String (avoids making new STR_Strings just to do the lookup).
- CValue::SetPropertiesModified() and CValue::SetPropertiesModified(), were looping through all items in the std::map, advancing from the beginning each time.
Deprecated..
getPosition, setPosition, getOrientation, setOrientation, getState, setState, getParent, getVisible, getMass
* swapped set/get to get/set in KX_PYATTRIBUTE_RW_FUNCTION macro to match pythons getsetattrs.
* deprecation warnings in the api and notes in epydocs.
* added 'state' attribute
* gameob.mass = 10 # now works because its not checking only for float values.
* dir(gameob) # includes attributes now
other scenes, for texture face / multitexture materials.
Fix for bug #18428: BGE lights on hidden layers were still used,
for all material types, now they have no effect
Was adding each face with a remove doubles option that made conversion increasingly slower for larger meshes, this would often hang blender when starting with the BGE with larger meshes.
Replace btTriangleMesh()->addTriangle() with btTriangleIndexVertexArray()
YoFrankie level_1_home.blend starts a third faster, level_nut about twice as fast.
- previous commit was also incorrect using the original meshes vert locations rather then the vert locations that came from the derived mesh.
- Softbody is relying on removing doubles at 0.01 to give stable results, this no longer works but seems a bit dodgy anyway. Maybe some post-processing filter could fix up a mesh for bullet softbody.
Python dir(ob) for game types now includes attributes names,
* Use "__dict__" rather then "__methods__" attribute to be Python 3.0 compatible
* Added _getattr_dict() for getting the method and attribute names from a PyObject, rather then building it in the macro.
* Added place holder *::Attribute array, needed for the _getattr_up macro.
Removed a check in Python API touch.setProperty() for the property name on the sensor owner before allowing the name to be set - it makes no sense and isnt checked when creating the sensor.
- SCA_DelaySensor.py indent error making epydoc fail.
Previously only the first collision would trigger an event (no collisions a negative event ofcourse)
With the Pulse option enabled, any change to the set of colliding objects will trigger an event.
Added this because there was no way to count how many sheep were on a platform in YoFrankie without running a script periodically.
Changes in collision are detected by comparing the number of objects colliding with the last event, as well as a hash made from the object pointers.
Also changed the touch sensors internal list of colliding objects to only contain objects that match the property or material.
- pulse isnt a great name, could change this.
* Where possible use vec.setValue(x,y,z) to assign values to a vector instead of vec= MT_Vector3(x,y,z), for MT_Point and MT_Matrix types too.
* Comparing TexVerts was creating 10 MT_Vector types - instead compare as floats.
* Added SG_Spatial::SetWorldFromLocalTransform() since the local transform is use for world transform in some cases.
* removed some unneeded vars from UpdateChildCoordinates functions
* Py API - Mouse, Ray, Radar sensors - use PyObjectFrom(vec) rather then filling the lists in each function. Use METH_NOARGS for get*() functions.
- variables that shadow vers declared earlier
- Py_Fatal print an error to the stderr
- gcc was complaining about the order of initialized vars (for classes)
- const return values for ints and bools didnt do anything.
- braces for ambiguous if statements
This was committed in revision 2832 but never accounted for existing object name hashes which existed since revision 2.
Its possible to update the names elsewhere but unlikely anyone ever used this successfully so removing.
* fixed segfaults in CListValue.index(val) and CListValue.count(val) when the pyTypes could not be converted into a CValue.
* added scene.objects to replace scene.getObjectList()
* added function names to PyArg_ParseTuple() so errors will include the function names
* removed cases of PyArg_ParseTuple(args,"O",&pyobj) where METH_O ensures a single argument.
* Made PyObjectFrom use ugly python api rather then Py_BuildValue(), approx %40 speedup for functions that return Python vector and matrix types like ob.orientation.
Use 'const char *' rather then the C++ 'STR_String' type for the attribute identifier of python attributes.
Each attribute and method access from python was allocating and freeing the string.
A simple test with getting an attribute a loop shows this speeds up attribute lookups a bit over 2x.
scene.getObjectList()[-1] works like a python sequence.
removed some STR_String creation that was only used to do comparisons, in a simple expressions benchmark this made logic use 4% less overall.
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.
