inspecting the type of key interpolation
Just wanted to check, there’s no way in expressions to determine the type of a specified key, is there?
For example:
//
// Designed to go in a sourceText property as a debugger
//
p = transform.position;n = 0;
if (p.numKeys > 0) {
n = p.nearestKey(time).index;
if (time < p.key(n).time ) {
// key n is ahead of us
n--;
}
}if (p.numKeys > n && n > 0) {
// there's at least one key after this one, and we're not before the first keyq = p.key(n).typeOf;
if (q == 'linear') {
// do something
}if (q == 'bezier') {
// do something else
}
} else {
// outside the current range of keys
}

I don’t know of any way to do that.

In that case, I doubt there is!

and you could use the difference of valueAtTime and valueAtTime on frame prior compared to the difference of valueAtTime for key1 and key2 divided by the frames separating those keys to determine if the interpolation was linear or not…

i actually just had the need to do this, and what i used was:
if (speedAtTime(key(2).time)==0){
// it’s soft interpolation
}else{
// it’s hard interpolation
}obviously, key(2) could be whatever key you needed to look at. and i assume it would work for velocityAtTime() also…
