this could be supported again easily however it leads typo's & api changes not showing any errors.
This broke povray export.
Solution for now is to allow setting private properties starting with '_'
eg,
ob = bpy.context.object
ob._foo = [1,2,3] # this is a python list, it will stay only as long as this PyObject is active
ob.foo = 1 # raises an error!, only for rna properties
ob["foo"] = 1 # converts to an ID property and is saved
using the underscore like this should really be used for classes internally.
- povray failed on armatures
- menu key wasn't using WM_keymap_add_menu
The advantage with this is that global property definitions are not needed to add a property to an object.
to avoid confusion these are accessed like a dictionary (closely matching how the BGE accesses properties)
ob["mySetting"] = 1.0
bone["foo"] = {"one":1, "two":2.1, "three":"Three"}
if "foo" in bone: print("prop found...")
At the moment these can also be accessed as attributes, will be changed shortly. eg.
bone.foo == bone["foo"]
eg.
scene.objects.link()
object.constraints.new()
mesh.verts.transform(...)
mesh.faces.active
PropertyRNA stores an StructRNA pointer where these can be defined.
- bpy is now a python package, this makes it easier to add utility modules and adjust python startup which was previously using verbose Py/C api. Access should not be any slower since both C and Python modules use dictionary access.
- loop over scripts and load via python (currently F8 reload isnt working, will add back shortly)
- the C module is kept but renamed to _bpy and not meant for direct access from anything but the bpy package.
- bpy_types.py is an exception since it runs before the bpy package is initialized.
- collection functions rename eg. bones_active -> bones__active, add_object -> objects__add since these should be accessed from the collections only.
- fix warnings in last commit
Added a group example
C = bpy.context
ob = C.active_object
bpy.data.groups[0].objects.add(ob)
- add_to_group and rem_from_group now take optional scene and base flags and deal with updating the object & base flags
- operators that add objects to groups were setting ob->recalc= OB_RECALC_OB; looks like its not needed.
- previously add() ignored python args, now add and remove are called like any other FunctionRNA from python.
- made the pyrna api use tp_getset's for collestions active/add()/remove()
crash on windows due to incompatible FILE struct between
Blender and python library, which is why it was not used
in 2.4x, so apply the same workaround now.
* Added 'active node' panel for the Nodes Editor. This panel, in the NKEY region, shows the settings for the active node. Included in this panel is a field used for editing the unique-name of the node too.
* Fixed a number of uninitialised vars warnings that I missed in previous commit...
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
this way the UI scripts are less likely to fail silently and wont let typos work ok.
also allow subclassing of the context, added a copy function,
bpy.context.copy(), returns the context as a python dict to be modified and used in python.
This also showed up an invalid brush member in the screen context.
- python defined classes will be used when available (otherwise automaically generated metaclasses are made as before)
- use properties rather then functions for python defined rna class's
- call the classes getattr AFTER doing an RNA lookup, avoids setting and clearing exceptions for most attribute lookups, tested UI scripts are ~25% faster.
- extending rna py classes this way is a nicer alternative to modifying the generated metaclasses in place.
Example class
--- snip
class Object(bpy.types.ID):
def _get_children(self):
return [child for child in bpy.data.objects if child.parent == self]
children = property(_get_children)
--- snip
The C initialization function looks in bpy_types.py for classes matching RNA structure names, using them when available.
This means all objects in python will be instances of these classes.
Python properties/funcs defined in ID py class will also be available for subclasses for eg. (Group Mesh etc)
- made the console banner printing function into a python operator (includes sys.version)
- added 'C' into the consoles default namespace for convenience
- more detailed exceptions (always give file:line incase the python exception doesnt)
- fix some errors in the edit docs
editing docs still fails, need to figure out why.
- made all exporters default to the blend filename with the extension replaced
- MDD's poll function now checks for an active mesh
- multiline docstrings are written as multiline docs when generating epydocs
ob.driver_add("location")
ob.driver_add("location", 0) # x location only
Also changed ANIM_add_driver so an index of -1 adds drivers to every item in the array
made this default for python so you can do...
pose_bone.keyframe_insert("location")
rather then
pose_bone.keyframe_insert("location", 0)
pose_bone.keyframe_insert("location", 1)
pose_bone.keyframe_insert("location", 2)
note that you can still set rna properties like this.
bpy.data.__dict__["var"] = 1
print(bpy.data.var)
but this is only stored for the python objects lifetime and not actually attached to blenders data
