Hey community,

I'm trying to figure out how I can trigger a VFXComponent to emit particles via script. My use-case is to emit particles at a certain time into an animation. The animation is looping which means I need to be able to trigger the particles many times. I'm currently using the Burst spawn mode. The Once spawn mode may also work although I found it changed my particles' scale.

Here are some of the things I've tried:

Calling the VFXComponent's reset() function
Toggling the component off and on
Making the VFX a prefab and instantiating it at emit time

But, I haven't been able to get it to work. Is what I'm trying to do possible?

Ah, I missed the Interactive Spawn Example on the VFX guide:

// @input Component.VFXComponent vfx
// @input float vfxEmitDuration = 0.1

animationEvent = script.createEvent("DelayedCallbackEvent");
animationEvent.bind(
    function (eventData)
    {
        script.vfx.asset.properties["emitUntilTime"] = getTime() + script.vfxEmitDuration;
    }
);

// ...

animationEvent.reset(2.0);
