Re: [ scripting ] Filter "NodeAnimatedParameters" to be only translate

[Nicolas Langlois <nicolasl(at)buzzimage.com>]

Stefan,

All right now that's clearer. What you're trying is to do each object 
one after the other so it's not on the keys or on the parameters that 
you need to iterate.

sels = xsi.Selection
goodSel = []

# Get all the objects that have an Fcurve to anymate any of their pos
for sel in sels:
	if sel.NodeAnimatedParameters(c.siFCurveSource)
       	for oFCurveAnimatedParam in oFCurveAnimatedParams:
               	if "pos" in oFCurveAnimatedParam.Name:
				goodSel.append(oFCurveAnimatedParam)

# Now offset them each after the other - Assuming you have only one pos param animated per object
for i in range(len(goodSel)):
	oFCurve = goodSel[i].Source
	oRange = oFCurve.GetKeysBetween(oIn, oOut)
	oFCurve.OffsetKeys(oRange, oTimeOffset * i)



Hope it helps!
