Get rotation of animated object with python
Anchorage last edited by
I'm trying to write python script for Cinema4D R17 that would go through all frames and output rotation of object that is animated. The script works but it always returns the same rotation even when object is animated and its rotation is changing in each frame. How do I fix this?
Here is the code I'm using
import c4d import c4d.utils import math from c4d import gui def main(): currentDoc = c4d.documents.GetActiveDocument() docFps = currentDoc.GetFps() lastFrame = currentDoc.GetMaxTime().GetFrame(docFps) print "Document framerate is " + str(docFps) print "Last frame is " + str(lastFrame) for x in range(0, lastFrame + 1): currentDoc.SetTime(c4d.BaseTime(x, docFps)) c4d.EventAdd() cubeObj = currentDoc.SearchObject("Cube") cubeObjRotation = cubeObj.GetAbsRot() cubeObjRotation = cubeObjRotation * 180 / math.pi print "Frame" + str(x) + " - Cube rotation is " + str(cubeObjRotation) if __name__=='__main__': main()

don't be surprised, I have turned your thread into a question.
The problem is, that the document will actually not be animated (or lets rather say, it will not be evaluated or executed) when calling SetTime(). Additionally you need to call ExecutePasses().
The BaseDocument manual in our C++ SDK documentation contains some extra information on this topic in the sections Time and Animate.
