patch [#23317] Changed some operators' RNA to accept lengths
by Lorenzo Tozzi (oni_niubbo)
with the minor change to use XYZ subtype rather then LENGTH.
An example of how this is useful - an importer mixin could define the filepath properties and a generic invoke function which can run the subclasses exec for each selected file.
- Panels and Menus now skip the property check when registering.
- renamed _idproperties_ to _idprops_ in function names, function names were getting very long.
- raise an exception when python calls is_property_set(name) or is_property_hidden(name) and the property does not exist.
- added BLI_findstring_ptr(), which finds a named item in a listbase where that name is a pointer to a string.
- replaced inline for loops with calls to BLI_findstring_ptr() and IDP_GetPropertyFromGroup().
Modifiers were being mistakenly recalculated at every frame as long as the object had animation, slowing things down due to incorrect depsgraph recalc tags.
Renamed OB_RECALC -> OB_RECALC_ALL to reduce future confusion. During this process, I noticed a few dubious usages of OB_RECALC, so it's best to use this commit as a guide of places to check on. Apart from the place responsible for this bug, I haven't changed any OB_RECALC -> OB_RECALC_OB/DATA in case that introduces more unforseen bugs now, making it more difficult to track the problems later (rename + value change can be confusing to identify the genuine typos).
Throwing an exception if the strings too long means scripts need to be aware of string lengths and changing a string length in RNA can too easily break scripts.
Instead honor the string length in RNA_property_string_set()
Added automatic generation of lookup_int callbacks for collections, for
quicker lookup by index instead of looping over the whole thing. Import
is still quite slow, though now it only takes a few seconds.
The next bottleneck seems to be running update (depsgraph, notifiers, ..)
on setting every property. I fixed part of that by avoiding a notifier
to be added each time, now it checks for duplicates.
was doing an extra lookup for the functions property, as well as using the property iterator.
(every button & menu item draws does one of these for every redraw).
Many string properties need tweaks to work correctly with this, since many don't have any reasonable defaults set (especially name fields, which often get cleared with these changes).
This is set on keymap item operator properties and macro definition operator properties to make them non-contextual (since the context at definition time is most likely not the same then at execution time, it's better to have all options visible).
This removes some more errors in keymap export and import.
This commit also sanitize some enum item function, making sure they can cope with null context and have usable defaults in that case.
Added a check in RNA_property_animateable() which checks if the base ID-block can have animation data or not. Screen data currently cannot have animation data, so this solves that problem (where there were non-functional entries there in the menu).
Fixed and completed support for returning multiple values. This includes support for returning arrays, both fixed and dynamically sized. The way this is achieved is by storing an additional int value next to the dynamic parameter in the ParameterList stack which gets passed to the C function as an additional parameter. In the case of return parameters it is duty of the C function to set this int to the correct length value for the dynamic parameter (which makes sense). Note that for the dynamic output/return parameter it is assumed the function has allocated that memory (which gets freed automatically).
Also, I cleaned the makesrna's bridge function generation code a bit and renamed PROP_RETURN to PROP_OUTPUT, which represents better the reality now that there are multiple returns. The function now to mark multiple returns (outputs) is RNA_def_function_output.
For an example, look at Action.get_frame_range in rna_action_api.c, by the way Aligorith I removed the #ifdef for this function now that there's support for returning arrays, feel free to modify (the function seems to work).
blender supports type changing for textures in a way that python doesnt.
add a new general function.
Example usage:
tex = bpy.data.textures.new("Foo")
tex.type = 'IMAGE'
tex = tex.recast_type()
Macro to give the number of users accounting for fake user.
ID_REAL_USERS(id)
Use this so you can remove a datablock if it has a fake users as well as apply transformations to it in the 3D view.
Move api function bpy.data.add_texture() --> bpy.data.textures.new()/remove()
* Mostly revert #24880: Transform Locks affecting animation system. This
was implemented as a feature request from Nathan but was not the
intended functionality, and actually gives problems instead. The transform
locks should really only affect what the user can do, not if the property
can be animated internally.
* Revert #25868: fix for lib linked scenes not animating. This was needed
due to the above feature, but meant that all lib linked properties were
editable in the UI.
* Make bone properties of on proxy-protected layers not editable. They will
be overriden on reload/redo like lib linked data, so should not be edited.
from the report...
# bug 1. UV properties are not raw editable but are reported
# as RAW_TYPE_INT by RNA causing wrong conversion
# internally (bpy_rna.c line 2205)
# bug 2. raw update of UV coordinates crash blender (rna_access.c line 252)
mtfaces.foreach_set("uv", rawuvs)
# workaround:
#for i in range(int(len(faces)/4)):
# mtfaces[i].uv = uvs[i]
# bug 3. raw update of non-array property fails (rna_access.c line 2270)
mfaces.foreach_set("material_index", mats)
# workaround:
# for i in range(int(len(mfaces))):
# mfaces[i].material_index = mats[i]
# bug 4. It is not possible to add a vertex color layer using mesh API.
me.add_vertex_color()
# no workaround...
patch from Elia Sarti, (vekoon) with some modifications mainly for the python api.
- multiple values are returned as a typle in the order that are defined.
- added support for registered types returning multiple arguments (untested).
- renamed func->ret --> func->c_ret, since this only defines what the C function returns.
Finished wrapping Action Groups in RNA to help debug some bugs showing up in the Animation Editors for some files from the Durian team. Access is strictly read-only for these added settings, given the trouble already caused by these problems.
Until we have proper multi-object editing, this adds a Copy To Selected
option to the right mouse button menu for Object and Bone properties, to
copy the value from the active object to the selected objects.
Also includes some implementation changes to reset to default operator.
Added a new operator for properties which resets RNA-based settings to their 'default' values, as defined in RNA. This currently only works for floats, ints, enums, and booleans (strings and pointers still need to be implemented).
The current extensions to the RNA API that I've made here seem a bit excessive, and can be toned down if necessary. In short, I've just added accessor functions for the default-values of the property definitions.
For this to be really useful, many properties in RNA will need to get defaults defined, since the current defaults for quite a few properties tested were less than ideal.
