Bonjour,

J'essaie de trigger un node de CrowdBeEmit en fonction de l'animation de mon
entité, et pour éviter d'avoir 15 nodes d'expressions reliés par un
opérateur Or, je voulais utiliser un node de Script avec un array pour faire
ça, mais je n'arrive pas à faire fonctionner le système d'expressions dans
mon script MEL :


proc int isShooting(int $time){
int $frames[] = {10, 17, 21, 45, 49, 54, 59, 86, 115, 119, 226, 231,
236};
for ($f in $frames){
float $delta = $time -$f;
if (abs($delta) <= 0.5){
return true;
}
}
return false;
}
isShooting("##this.beMotionShape1.motionFrame##");


L'expression me renvoie 0 en permanence, je ne comprends pas où je me
trompe, merci d'avance!
Bonne journée,

Olivier

Hey there,

When using the public support list, please write your messages in english so the community can also answer / learn from your thread

Else you can use the private list :)

See inlined below:

You probably find that ##channel## syntax on the Golaem Expressions documentation page here

https://golaem.com/content/doc/golaem-crowd-documentation/expressions

This only gets evaluated when using Golaem Expressions but I'm afraid the Golaem Script Trigger is not part of this

You can evaluate your function the desired way in the Expression Trigger instead:

You'll have to source your function before running your simulation.

Probably using a Maya script node

This having been said, evaluating MEL function at every frame for every character is really not recommended as it'll slow down drastically your simulation

I'll still recommend splitting your function in separated Expression Nodes - even if this is cumbersome

In upcoming versions you'll be able to set an array of values in the Expression Trigger and other triggers requiring numerical values

Hope that helps

Best,

[Olivier MONTEIL]

Hi,

Thanks for the quick reply I will stick to the Or operator then.

Have a nice day,

Olivier
