- PyLong_FromSsize_t --> PyLong_FromLong
- PyLong_AsSsize_t --> PyLong_AsLong
In all places except for those where python api expects PySsize_t (index lookups mainly).
- use PyBool_FromLong in a few areas of the BGE.
- fix incorrect assumption in the BGE that PySequence_Check() means PySequence_Fast_ functions can be used.
This commit makes BKE_image_acquire_ibuf referencing result, which means once
some area requested for image buffer, it'll be guaranteed this buffer wouldn't
be freed by image signal.
To de-reference buffer BKE_image_release_ibuf should now always be used.
To make referencing working correct we can not rely on result of
image_get_ibuf_threadsafe called outside from thread lock. This is so because
we need to guarantee getting image buffer from list of loaded buffers and it's
referencing happens atomic. Without lock here it is possible that between call
of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would
be called. Image signal handling too is blocking now to prevent such a
situation.
Threads are locking by spinlock, which are faster than mutexes. There were some
slowdown reports in the past about render slowdown when using OSX on Xeon CPU.
It shouldn't happen with spin locks, but more tests on different hardware would
be really welcome. So far can not see speed regressions on own computers.
This commit also removes BKE_image_get_ibuf, because it was not so intuitive
when get_ibuf and acquire_ibuf should be used.
Thanks to Ton and Brecht for discussion/review :)
- IntValue's GetNumber() was convert int -> float -> double.
- BL_Shader was using STR_String rather then char*, where most callers had a char*, use a char* to avoid STR_String conversion-and-alloc on shader access.
* jump() -- causes the character to jump
* onGround -- specifies whether or not the character is on the ground
* gravity -- controls the "gravity" that the character physics uses for the character
More options could be added (such as jump speed, step height, make fall speed, max slope, etc).
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
viewport. This helps to eliminate OpenGL calls in weird places like the physics
code and to reduce glGet calls, which are expensive.
There should be no functional changes (except maybe a very slight speed improvement).
* KX_GameObject.member returns the list of group members if the object is a group object, otherwise None is returned
* KX_GameObject.group returns the group object that the object belongs to or None if the object is not part of a group
