Expression error in walk cycle

[Krollspell]

Hi

When i make an automated walk cycle i get 2 expression errors on the arm (no swinging or moving of the arms at all)


------------------ On the clavicle rotation and the arm rotation i get an "Undefined value used in expression" ---------------------------

//Duik.proceduralWalk
amp = effect("Walk Cycle")(45).value;
cycleTime = effect("Walk Cycle")(105).value;
armsSoftness = effect("Walk Cycle")(46).value;
characterSoftness = effect("Walk Cycle")(22).value;
energy = effect("Walk Cycle")(110).value;
walkSpeed = effect("Walk Cycle")(27).value;
left = false;
if (walkSpeed <0) left = true;
amp = amp*5*energy/100;
if (amp > 0)
{
softness = armsSoftness + characterSoftness;
decalage = 1.5;
amorti = 0;
sin = Math.sin(cycleTime*Math.PI*2+decalage);
for(i=0;i<amorti;i++) {
sin = Math.sin(sin);
}
rot = sin*amp;
rot = rot + rot*softness/100;
if (left) -rot;
}
else 0;

-------------------------------------------------------------------

...Any on else with this problem?

Hi,

Are you on AE CC2019?
If so it may be an issue with the new expression engine, which I'll have to fix (let me know). A workaround is to set the expression engine to "legacy" in the project parameters.

Hi,

Thanks for responding and for the amazing work you are doing!
Yes i'm on CC2019, and everything works when I set the Expression Engine to legacy...

The new Javascript engine produces 6 expression errors in the walkcycle, Clavicle, Arm and foot roll (right and left side)

Thanks for your feedback, I'll fix this in the next update

Same here. It worked when i turnd projectexpressions to (extend script) instead of java script on AE2019
