- was using un-initialized stack memory if the source / target object had no vertex group.
- if the target object had no vertex groups it would fails silently (not a bug but not very good functionality)
- added an error message if any copying fails.
Made my 3 new buttons only appear in weight paint mode when there are vertex groups present
in properties_data_mesh.py
I took the now redundant check box out of properties_data_mesh.py
I took out unnecessary code (resulting from copy/paste) from my lock all, unlock all, and invert all functions of object/object_vgroup.c
(and I got rid of a new line in paint_vertex.c :) )
vgroup functions were mixing up active group and one passed as an argument.
also made other changes.
- removed superfluous call to defvert_find_index() in vgroup_delete_object_mode(), was also doing unnecessary NULL check on each loop.
- remove paranoid NULL check from ED_vgroup_vert_remove, callers all check for valid 'ob'

========================
cube = bpy.data.objects['Cube']
foo = cube.vertex_groups.new('foo')
foo.add([1,3,5,7], 1.0, 'ADD')
for i in range(len(cube.data.vertices)):
try:
weight = foo.weight(i)
print('vert: %i weight: %f' % (i, weight))
except:
pass
foo.remove([1,3])
cube.vertex_groups.remove(foo)
only tags the ID and does the actual flush/update delayed, before the next
redraw. For objects the update was already delayed, just flushing wasn't
yet.
This should help performance in python and animation editors, by making
calls to RNA property update quicker. Still need to add calls in a few
places where this was previously avoided due to bad performance.
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
- fixed this error 7 different functions (deform groups, uv layers & similar).
- support for numbers over 999.
- renamed splitIDname() to BLI_split_name_num(), moved to BLI_path_utils
obj.add_vertex_group() --> obj.vertex_groups.new()
obj.add_vertex_to_group() --> obj.vertex_groups.assign()
note: obj.vertex_groups.assign() will be very slow, need to have this take a list rather then 1 vertex at a time.
scene.active_keying_set --> scene.keying_sets.active
...same for active_uv_texture. active_vertex_color, active_keyconfig,
- move mesh.add_uv_layer() and mesh.add_vertex_color() into their collections
also have them return the newly created layer and dont set the layer active.
uvtex = mesh.uv_layers.new(name)
vcol = mesh.vertex_colors.new(name)
