This allows us to ensure that a given NodeTree is only ever exported once.
A node reference acts as a way to attach a plMultiModifier to a
plSceneObject without using those terms. Things will work just fine if the
node reference isn't used, so as long as the entire tree is only used
once.
Future work: ensuring the whole logic tree is only ever exported once.
To ensure that there are really, really, REALLY no race conditions related
to coordinate interfaces, we now run through all modifiers before we
export and ask them if they need to make Coordinate Interfaces. I was
hearing some comments about clickables warping around. This sounds like
physical coordinate issues to me...
So this is a fairly massive chunk. I tried to get our Plasma Modifiers to
match the Blender Modifier UI fairly well. In the process, I discovered
that Blender "helpfully" hides the modifier button on Empty objects. Bah.
Significant Changes:
- Hid all of the Blender Physics mess
- The Physics context is now the Plasma Object context
- Moved Plasma Object and Plasma Synchronization to the Context Formerly
Known as Physics
- Added a Plasma Modifier Panel
Here's how you create Plasma Modifiers:
- Add your PropertyGroup to properties.modifiers
- Make sure you have a pl_id naming your modifier, a category, and a label
- Implement the export() method to actually export something useful (not
goat porn, please)
- Implement your UI draw function in ui.modifiers.
- Wasn't that easy?
We are attempting to encourage the pages=layers paradigm; however, this is
not strictly enforced. This commit has lots of bits and bobs but little
actual substance. More to come when I begin work on the exporter.
