Simulation input and output nodes are currently added individually, but they always need to exist as pair. This PR modifies the _Add Node_ menu so that a single menu entry adds and input and output node together.
The `NODE_OT_add_node` operator currently adds just a single node type. A new variant of this operator is added which adds a _simulation zone_ with origin + target node instead. This requires some modification of the `NodeAddOperator` base class, moving the `node_type` property into the final implementation. Unlike the `NODE_OT_add_node` operator, the `NODE_OT_add_simulation_zone` adds 2 different node types.
After adding the two nodes, a reference needs to be added to "pair" them: Input node ("origin") stores the UID of the output node ("target") in its `output_node_id` property. So far this was detected automatically when adding an input, but this method is not very robust (e.g. it depends on order of adding nodes and adding multiple pairs can be tricky).
Now the pairing is done explicitly through an API function `node_geo_simulation_input_pair_with_output`. The `NODE_OT_add_simulation_zone` operator performs pairing of the input/output nodes after adding them. The function is accessible through RNA, so an operator may be added if necessary to allow users to fix unpaired nodes.
In addition to pairing the two nodes, the operator also positions them at a comfortable distance, as well as adding a default link between the two Geometry sockets for convenience.
Resolves#105727
Pull Request: blender/blender#106557
This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
