Description

have an error while creatin a key on 0frame and while there is no another key.

yep, array index in mxs start from 1,
so check if there are keys (a > 0): 

a = getKeyIndex obj.speed.controller s
if a > 0 do (
    obj.speed.controller.keys[a].inTangentType = #linear
    obj.speed.controller.keys[a].outTangentType = #fast
)

need help about "inTangentType"

on a frame that is not "0f" it works well
on frame which is not "0f" it works well
but on frame "0f" and if there isn't another animation key,
it gives an error.
can anyone help me about the error.
