Call Function Script Using Send Custom Trigger (Behavior)
Hi, is there a way for calling script function ( for example testFunction() ) using "send custom trigger" in the behavior script? ( or similar way )
Here's a pic from my script, this script used for "Screen Image (named myObject)"

And here's a pict when behavior script call testFunction() function

Sending a custom trigger is meant to trigger another behavior script. What you want to do instead is set the response type to "Call Script API" and in your script make sure you've exposed your function using script.api.
