vortxGE 2.0 progress : Blender animaion export

After bashing my head against a wall for a day, I think I have the basic export working. Only one thing that I'm not sure on, the RNA array_index? I'm using it as the x,y,z reference in my own properties and I'm hoping this is right LOL. Here's the code.

EDIT: code update to include skeleton support.


# -*- coding: utf-8 -*-

# vortX GE export animation

import os
from math import radians

import bpy
from mathutils import *


# my OP ###

class ExportVXA(bpy.types.Operator):
bl_idname = "object.export_vxa"
bl_label = "Export VXA"

@classmethod
def poll(cls, context):
return context.active_object != None

def objToLine( self, obj ):
line = "find_actor "
line += obj.name
return line[:] + "\n"

def fpsToLine( self, scn ):
line = "set_animframerate "
# fps
line += str( scn.render.fps )
return line[:] + "\n"

def keysToLines( self, scn, obj ):
line = ""
if obj.animation_data:
Action = obj.animation_data.action
if Action:
for FCurve in Action.fcurves:
if FCurve:
line += "\naddkeys "
line += FCurve.data_path
line += " "
line += str( FCurve.array_index )
line += "\n"
for Keyframe in FCurve.keyframe_points:
print( Keyframe.co )
line += "addkey "
line += str( Keyframe.co[0] )
line += " "
line += str( Keyframe.co[1] )
line += "\n"

return line[:] + "\n"

def outvxa(self, path, scn, obj ):
filename = path + obj.name + ".vxa"
file = open(filename, "w")
file.write("# vortX GE animation v0.1\n\n")

file.write(self.objToLine( obj ))
file.write(self.fpsToLine( scn ))
file.write(self.keysToLines( scn, obj ))

file.close()

def execute(self, context):
print("Run Export VXA")
# print( dir( context ) )
rd = context.scene.render
path = rd.filepath
obj = context.active_object
scn = context.scene
self.outvxa(path, scn, obj)
return {'FINISHED'}

# my PANEL
class OBJECT_PT_export_vxa(bpy.types.Panel):
bl_label = "Export VXA"
bl_space_type = "PROPERTIES"
bl_region_type = "WINDOW"
bl_context = "object"

def draw(self, context):
layout = self.layout
rd = context.scene.render
obj = context.active_object

row = layout.row()
row.label(text="Active Object : " + obj.name)

row = layout.row()
layout.prop(rd, "filepath", text="")

row = layout.row()
row.operator("object.export_vxa", text="Export Animation")

def register():
bpy.utils.register_class(ExportVXA)
bpy.utils.register_class(OBJECT_PT_export_vxa)

def unregister():
bpy.utils.unregister_class(OBJECT_PT_export_vxa)
bpy.utils.unregister_class(ExportVXA)

if __name__ == "__main__":
register()


And here is the output file.
