Hi
i have tried with MODATA_LASTMAT read the previous postion to get the speed.
I'm very new to Python but would happy to make this effect
But get at MODATA_LASTMAT only (0,0,0) as output.
Any help?
(Googel Translator)import c4d
from c4d.modules import mograph as mo#Welcome to the world of Python
def main() :
md = mo.GeGetMoData(op)
if md==None: return False
cnt = md.GetCount()
marr = md.GetArray(c4d.MODATA_MATRIX)
marr_p = md.GetArray(c4d.MODATA_LASTMAT)
col = md.GetArray(c4d.MODATA_COLOR)
for i in xrange(0, cnt) :
a = marr _.off
b = marr_p _.off
print b
md.SetArray(c4d.MODATA_MATRIX, marr, True)
md.SetArray(c4d.MODATA_COLOR, col, True)
return True -

Turtle, I'm pretty sure you already contacted me earlier today, and I already gave you all the info you need.
MODATA_LASTMAT doesn't give you the previous matrix, you need to store the previous matrix yourself. Then you can calculate the velocity.
speed = (marr[i].off - prevmarr[i].off).GetLength()
You can then map that speed to whatever mograph property you want.I got a video coming soon that elaborates more on the concept and a couple files that come with it.
For now, you can check out this project file from krotmonster, which uses the same concept :
Not sure what else you expect ?
This is all basic programming and all the info is already out there.
Please do at least a little effort first, and do some research ! That's the only way to learn.A few google queries will quickly point you to a few related threads on a number of boards.
You'll also come across Lennart from tcastudios as well. He's the guy who initially inspired me to these setups.Have fun exploring !!
