Hi all,
currently I'm doing the tutorial for Chad Vernon's Custom Jiggle
Deformer tutorial but trying to convert the code into Python just to understand
better the anatomy of building a Deformer. I'm stuck right now at this error
// Error: file: C:/Program Files/Autodesk/Maya2013/scripts/others/pluginWin.mel
line 665: RuntimeError: file G:/AdvancedScripting/jiggleFinal.py line 48:
(kInvalidParameter): Cannot find item of required type //
// Warning: file: C:/Program
Files/Autodesk/Maya2013/scripts/others/pluginWin.mel line 665: Failed to call
script creator function //
Everytime I load in my plugin, I haven't implemented the main code yet just
trying if the thing could load. The section of code it's complaining about is
here:
def initialize():
nAttr = api.MFnNumericAttribute()
uAttr = api.MFnUnitAttribute()
mAttr = api.MFnMatrixAttribute()
cAttr = api.MFnCompoundAttribute()
outputGeom = apiMPx.cvar.MPxDeformerNode_outputGeom
Jiggle.aTime = uAttr.create('time', 'time',
api.MFnUnitAttribute.kTime,0.0)
Jiggle.addAttribute(Jiggle.aTime)
Jiggle.attributeAffects(Jiggle.aTime, outputGeom)
Jiggle.aStartFrame = nAttr.create("startFrame", "startFrame",
api.MFnNumericData.kInt, 0)
nAttr.setKeyable(True)
Jiggle.addAttribute(Jiggle.aStartFrame)
Jiggle.attributeAffects(Jiggle.aStartFrame, outputGeom)
Attached is the main code. Would appreciate if anyone could tell me what I'm
doing wrong
Thank you
Bay
