after discussion over the mailing-list it seems that it really makes no sense to restrict that. Specially since we have the "Property" playback mode that usually will be a float.
Since there is no need for do_version or whatoever I don't see a problem. Any Thoughts? Maube to allow it only through the Python API?
This is a bug as old as the ability to change the actuator values through Python.
For the records: although Blender supports floats as frame values BGE doesn't. It could but it doesn't. So only integers (longs) will be valid start/end frames.
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.
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* Game and sequencer RNA, and sequencer header are now out of date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.
- comments to PyObjectPlus.h
- remove unused/commented junk.
- renamed PyDestructor to py_base_dealloc for consistency
- all the PyTypeObject's were still using the sizeof() their class, can use sizeof(PyObjectPlus_Proxy) now which is smaller too.
Use each types dictionary to store attributes PyAttributeDef's so it uses pythons hash lookup (which it was already doing for methods) rather then doing a string lookup on the array each time.
This also means attributes can be found in the type without having to do a dir() on the instance.
- 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.
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.
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.
* removed macros that were not used much, some misleading.
* removed error string setting calls that overwrote the error set by PyArg_ParseTuple with a less useful one.
* use python macros Py_RETURN_NONE, Py_RETURN_TRUE, Py_RETURN_FALSE
New Add mode for Ipo actuator
=============================
A new Add button, mutually exclusive with Force button, is available in
the Ipo actuator. When selected, it activates the Add mode that consists
in adding the Ipo curve to the current object situation in world
coordinates, or parent coordinates if the object has a parent. Scale Ipo
curves are multiplied instead of added to the object current scale.
If the local flag is selected, the Ipo curve is added (multiplied) in
the object's local coordinates.
Delta Ipo curves are handled identically to normal Ipo curve and there
is no need to work with Delta Ipo curves provided that you make sure
that the Ipo curve starts from origin. Origin means location 0 for
Location Ipo curve, rotation 0 for Rotation Ipo curve and scale 1 for
Scale Ipo curve.
The "current object situation" means the object's location, rotation
and scale at the start of the Ipo curve. For Loop Stop and Loop End Ipo
actuators, this means at the start of each loop. This initial state is
used as a base during the execution of the Ipo Curve but when the Ipo
curve is restarted (later or immediately in case of Loop mode), the
object current situation at that time is used as the new base.
For reference, here is the exact operation of the Add mode for each
type of Ipo curve (oLoc, oRot, oScale, oMat: object's loc/rot/scale
and orientation matrix at the start of the curve; iLoc, iRot, iScale,
iMat: Ipo curve loc/rot/scale and orientation matrix resulting from
the rotation).
Location
Local=false: newLoc = oLoc+iLoc
Local=true : newLoc = oLoc+oScale*(oMat*iLoc)
Rotation
Local=false: newMat = iMat*oMat
Local=true : newMat = oMat*iMat
Scale
Local=false: newScale = oScale*iScale
Local=true : newScale = oScale*iScale
Add+Local mode is very useful to have dynamic object executing complex
movement relative to their current location/orientation. Of cource,
dynamics should be disabled during the execution of the curve.
Several corrections in state system
===================================
- Object initial state is taken into account when adding object
dynamically
- Fix bug with link count when adding object dynamically
- Fix false on-off detection for Actuator sensor when actuator is
trigged on negative event.
- Fix Parent actuator false activation on negative event
- Loop Ipo curve not restarting at correct frame when start frame is
different from one.
