9161d3ce4b use Py_ssize_t rather than int when dealing with list sizes (original patch from Fedora but applied changes elsewhere too), also replace PyList_Size with PyList_GET_SIZE where typechecking is already done. 2011-09-06 23:46:20 +00:00

9521fa9456 remove gameOb.has_key(key) method from KX_GameObject and ListValue since python 3.x removes has_key from dictionaries.
Instead use __contains__, eg.
 if key in gameOb: ...
 
Mathutils returns from PyMath.cpp were incorrectly using wrapped Mathutils types. Wrapped types should only be used with a callback now.

9a7ea9664e BGE PyAPI support for subclassing any BGE game type from python, scripters define extra functions on gameObjects.
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.

6b9f3b5f5c BGE Python API
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.

8e882d0d61 Bug in KX_GameObject.get() and ListValue.get(), wasn't checking if the CValue derived objects could be converted to a PyObject.
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.

- 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.

386122ada6 BGE performance, 4th round: logic
This commit extends the technique of dynamic linked list to the logic
system to eliminate as much as possible temporaries, map lookup or 
full scan. The logic engine is now free of memory allocation, which is
an important stability factor. 

The overhead of the logic system is reduced by a factor between 3 and 6
depending on the logic setup. This is the speed-up you can expect on 
a logic setup using simple bricks. Heavy bricks like python controllers
and ray sensors will still take about the same time to execute so the
speed up will be less important.

The core of the logic engine has been much reworked but the functionality
is still the same except for one thing: the priority system on the 
execution of controllers. The exact same remark applies to actuators but
I'll explain for controllers only:

Previously, it was possible, with the "executePriority" attribute to set
a controller to run before any other controllers in the game. Other than
that, the sequential execution of controllers, as defined in Blender was
guaranteed by default.

With the new system, the sequential execution of controllers is still 
guaranteed but only within the controllers of one object. the user can
no longer set a controller to run before any other controllers in the
game. The "executePriority" attribute controls the execution of controllers
within one object. The priority is a small number starting from 0 for the
first controller and incrementing for each controller.

If this missing feature is a must, a special method can be implemented
to set a controller to run before all other controllers.

Other improvements:
- Systematic use of reference in parameter passing to avoid unnecessary data copy
- Use pre increment in iterator instead of post increment to avoid temporary allocation
- Use const char* instead of STR_String whenever possible to avoid temporary allocation
- Fix reference counting bugs (memory leak)
- Fix a crash in certain cases of state switching and object deletion
- Minor speed up in property sensor
- Removal of objects during the game is a lot faster

0c482f7607 BGE API - small changes
- 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.

6a270ecb94 BGE Python API
CListValue fixes
- Disable changing CValueLists that the BGE uses internally (scene.objects.append(1) would crash when drawing)
- val=clist+list would modify clist in place, now return a new value.
- clist.append([....]), was working like extend.
- clist.append(val) didnt work for most CValue types like KX_GameObjects.

Other changes
- "isValid" was always returning True.
- Set all errors for invalid proxy access to PyExc_SystemError (was using a mix of error types)
- Added PyObjectPlus::InvalidateProxy() to manually invalidate, though if python ever gains access again, it will make a new valid proxy. This is so removing an object from a scene can invalidate the object even if its stored elsewhere in a CValueList for eg.

5553d2c014 BGE C++ API
PyObjectPlus::ProcessReplica() is now called when any of its subclasses are replicated.

This is important because PyObjectPlus::ProcessReplica() NULL's the 'm_proxy' python pointer I added recently.
Without this a replicated subclass of PyObjectPlus could have an invalid pointer (crashing the BGE).

This change also means CValue::AddDataToReplica() can be moved into CValue::ProcessReplica() since ProcessReplica is always called.

Separate getting a normal attribute and getting __dict__, was having to do too a check for __dict__ on each class (multiple times per getattro call from python) when its not used that often.

- More verbose error messages.
- BL_Shader wasnt setting error messages on some errors
- FilterNormal depth attribute was checking for float which is bad because scripts often expect ints assigned to float attributes.
- Added a check to PyVecTo for a tuple rather then always using a generic python sequence. On my system this is over 2x faster with an optmized build.

8d2cb5bea4 BGE Python API
This changes how the BGE classes and Python work together, which hasnt changed since blender went opensource.
The main difference is PyObjectPlus - the base class for most game engine classes, no longer inherit from PyObject, and cannot be cast to a PyObject.

This has the advantage that the BGE does not have to keep 2 reference counts valid for C++ and Python.

Previously C++ classes would never be freed while python held a reference, however this reference could be problematic eg: a GameObject that isnt in a scene anymore should not be used by python, doing so could even crash blender in some cases.

Instead PyObjectPlus has a member "PyObject *m_proxy" which is lazily initialized when python needs it. m_proxy reference counts are managed by python, though it should never be freed while the C++ class exists since it holds a reference to avoid making and freeing it all the time.
When the C++ class is free'd it sets the m_proxy reference to NULL, If python accesses this variable it will raise a RuntimeError, (check the isValid attribute to see if its valid without raising an error).
- This replaces the m_zombie bool and IsZombie() tests added recently.

In python return values that used to be..
 return value->AddRef();
Are now
 return value->GetProxy();
or...
 return value->NewProxy(true); // true means python owns this C++ value which will be deleted when the PyObject is freed

df8cf26404 Added m_zombie to the base python class (PyObjectPlus), when this is set all the subclasses will raise an error on access to their members.
Other small changes...
- KX_Camera and KX_Light didnt have get/setitem access in their PyType definition.
- CList.from_id() error checking for a long was checking for -1 against an unsigned value (own fault)
- CValue::SpecialRelease was incrementing an int for no reason.
- renamed m_attrlist to m_attr_dict since its a PyDict type.
- removed custom getattro/setattro functions for KX_Scene and KX_GameObject, use py_base_getattro, py_base_setattro for all subclasses of PyObjectPlus.
- lowercase windows.h in VideoBase.cpp for cross compiling.

33170295c8 use long long rather then int for storing game logic properties.
There were also some problems with int to python conversion
- assigning a PyLong to a KX_GameObject from python would raise an error
- PyLong were coerced into floats when used with internal CValue arithmetic

Changes...
- PyLong is converted into CIntValue for coercing and assigning from python
- CValue's generic GetNumber() function returns a double rather then a float.
- Print an error when a PyType cant be coerced into a CValue

Tested with python, expressions and property sensor.

4cd088b105 BGE Py API
- 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.

- 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]))

fd2b115678 Python BGE API
- 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()

d573e9c539 BGE Python api
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

* 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.

cdec2b3d15 BGE Python API
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.
