the `pre_export_optional_cube_region` function is a decent idea, but it
predates the ability to do things like `foo = yield bar()` in
`pre_export()` generator methods. So, we remove it in favor of yielding
and assigning in one line. This should clean up some noisy warnings from
Blender after the export is over.
This means you can't add VisRegions to your GUI pages. You also can't
make an empty object be a panic link region. Those kinds of things just
don't make sense.
- The object the modifier is on is now the clickable (matches the
behavior of journals).
- Improved object selector icons.
- Automatically generate a clickable region.
- Alert if no camera is set.
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.
Previously, reusing node trees required careful thought and
specification of specific nodes in the advanced logic modifier. This
tedious requirement has been removed in favor of ensuring that the nodes
themselves take into account whether or not they should generate and
attach plasma objects.
"Improve" is not quite the correct verbiage here because there were bugs
in the old code. The main issue is that any SceneObject with a
plPythonFileMod attached MUST have a CoordinateInterface attached,
otherwise the object would be invisible in game. Further, there were
some unreported oversights with regard to auto-generated modifiers that
have been fixed.
Plasma game installs are a per-user config item and should not be stored
in a blend file. Considering that we will be adding more per-user
configs, namely Python 2.[2|3|7] install directories, it seems like a
good move to go ahead and move the games over.
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.
