Previously, this functionality was implemented in context-dependent operators. Considering that Korman is becoming increasingly complex and is now generating entirely new objects (potentially with modifiers) as part of its export process, it was becoming cumbersome to use those operators.
In a previous changeset, the Advanced Logic modifier was changed to
defer exporting logic until the very end of the export process. This
means that many nodes are designed with the assumption that all
non-logic PRP objects are fully exported by the time they are exported.
LogicWiz modifiers, however, violated this assumption by exporting
during the main export() phase.
So, this adds a new `pre_export()` phase for all modifiers that lets
them generate logic trees and even entirely new Plasma Objects safely.
Futher, old LogicWiz modifiers have been tweaked to not leak junked
objects if the export fails in the middle of those modifiers.
This changeset ensures that if a dependant modifier's dependency is
deleted that the aforementioned modifier is deleted as well. Since this is
something of a large change, we ask for the user to confirm the operation
before actually doing so.
This commit adds a footstep region modifier that exports nothing at the
moment. This is just a test case for logic node generation. If you want to
bake footstep regions into logic nodes, select an object and execute
`bpy.ops.object.plasma_logicwiz()`. :)
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?
