- print CListValue errors only once.
- bge_api_validate_py.txt now validates modules as well as types.
- added missing functions and consts for epydoc modules. some of these in GameLogic.py still need sorting.
getScreenPosition(obj):
- Gets the position of an object projected on screen space.
getScreenVect(x, y):
- Gets the vector from the camera position in the screen coordinate direction.
getScreenRay(x, y, dist, property):
- Look towards a screen coordinate (x,y) and find first object hit within dist that matches prop.
- The ray is a call to KX_GameObject->rayCastTo from the KX_Camera object.
Patch [#18589] test files can be found there. Patch reviewed by Campbell
- initialize pythons sys.argv in the blenderplayer
- ignore all arguments after a single " - " in the blenderplayer (like in blender), so args can be passed to the game.
- add a utility function PyOrientationTo() - to take a Py euler, quat or 3x3 matrix and convert into a C++ MT_Matrix3x3.
- add utility function ConvertPythonToMesh to get a RAS_MeshObject from a KX_MeshProxy or a name.
- Added error prefix arguments to ConvertPythonToGameObject, ConvertPythonToMesh and PyOrientationTo so the error messages can include what function they came from.
- deprecated brick.getOwner() for the "owner" attribute.
- no source code since this is only useful if the epydocs contain code, ours are only docstrings.
- set inheritance to included so you dont have to search up the classes to find available functions.
- SConstruct, isolate the exception for importing epydoc.
- Added a print to the SConscript files otherwise it looks like nothings happening.
- fix for multiple viewpors broke single viewport (both work now)
- python could get uninitialized values from m_prevTargetPoint and m_prevSourcePoint
- getting the RayDirection for python could crash blender trying to normalize a zero length vector.
- added python attributes
- removed unused canvas from the MouseFocusSensor class
Common cases of this are when python references an object from the AddObject actuator that has ended, or a scene has been loaded and the old objects freed.
This means some scripts will raise errors now in certain cases but better give the error early rather then failing silently with strange hard to track down behavior & crashes.
Added "isValid" attribute for checking objects are in a scene.
At the moment it uses the SceneGraph Node to check of the objects valid but it might be better to do this in a more generic way so scenes, meshes etc also have this check.
Clamp objects min/max velocity.
Accessed with bullet physics from the advanced button with dynamic and rigid body objects.
- useful for preventing unstable physics in cases where objects move too fast.
- can add linear velocity with the motion actuator to give smooth motion transitions, without moving too fast.
- minimum velocity means objects don't stop moving.
- python scripts can adjust these values speedup or throttle velocity in the existing direction.
Also made copy properties from an object with no properties work (in case you want to clear all props)
Added occlusion culling capability in the BGE.
More info: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.49/Game_Engine#BGE_Scenegraph_improvement
MSVC, scons, cmake, Makefile updated.
Other minor performance improvements:
- The rasterizer was computing the openGL model matrix of the objects too many times
- DBVT view frustrum culling was not properly culling behind the near plane:
Large objects behind the camera were sent to the GPU
- Remove all references to mesh split/join feature as it is not yet functional
- setting the scene attributes would always add to the scenes custom dictionary.
- new CListValue method from_id(id)
so you can store a Game Objects id and use it to get the game object back.
ob_id = id(gameOb)
...
gameOb = scene.objects.from_id(ob_id)
This is useful because names are not always unique.
- added keyboard senser attribute "events" to replace getEventList()
- fix 2 memory leaks in the python api (was making a list but not returning it)
- setting readonly attributes didnt give a good error message.
- Raised limit of 2 axis to 4 axis pairs (4==8 joysticks axis pairs)
- Added a new Joystick Sensor type "Single Axis", so you can detect horizontal or vertical movement, rather then just Up/Down/Left/Right
- added Python attribute "axisSingle" so you can get the value from the selected axis (rather then getting it out of the axis list)
- renamed Py attribute "axisPosition" to "axisValues" (was never in a release)
If we need to increase the axis limit again just change JOYAXIS_MAX and the button limits.
- added a module for the BGE - GameTypes, only contains types.
- added KX_PYATTRIBUTE_DUMMY attributes for KX_Light, KX_PolyProxy, KX_VertexProxy, so all types should give correct results from a dir().
- added a script to check for missing methods in the epydocs - bge_api_validate_py.txt
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.
- changed epy_docgen.sh so inherited attributes & methods are included inline for each type, removed source option since its not useful and makes the download bigger.
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
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.
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.
* Made GameLogic.addActiveActuator(actu, bool) to raise an error if the actuator is not in the list. Before it would allow any value as the actuator and fail silently (makes debugging scripts more difficult).
* Allow the actuator to be a string which is convenient if you dont want to change the settings of the actuator.
* Added activate/deactivate functions to the controller, this is more logical since the GameLogic.addActiveActuator() function is running through the controller anyway.
GameLogic.addActiveActuator(controller.getActuator("SomeAct"), True)
...can be replaced with...
controller.activate("SomeAct")
The principle is to replace most get/set methods of logic bricks by direct property access.
To make porting of game code easier, the properties have usually the same type and use than
the return values/parameters of the get/set methods.
More details on http://wiki.blender.org/index.php/GameEngineDev/Python_API_Clean_Up
Old methods are still available but will produce deprecation warnings on the console:
"<method> is deprecated, use the <property> property instead"
You can avoid these messages by turning on the "Ignore deprecation warnings" option in Game menu.
PyDoc is updated to include the new properties and display a deprecation warning
for the get/set methods that are being deprecated.
