Question by Tyler Starr · Feb 06, 2011 at 07:13 PM · nullreferenceexceptiongetcomponent

GetComponent help

I have this script:

function OnTriggerEnter(){

gameObject.GetComponent("Ellipsoid Particle Emitter").enabled = true;

}

But when i shoot at it to turn on the particle emitter for an explosion. I get the error NullReference Exception at line 3.

How can i fix this or is their an easier way to achieve this goal?

Thanks!!

I think you might want:

C#

gameObject.GetComponent<ParticleEmitter>().enabled = true;

Javascript

GetComponent.<ParticleEmitter>();

Try that.

$$anonymous$$uch better code, but gameObject isn't necessary. And in JavaScript, you need a dot. GetComponent.()

Heh, between Objective-C, C#, Javascript and Perl I get confused sometimes. $$anonymous$$y bad.

Did you set the particle system to auto destruct? If so, the best way to do it is to create a prefab out of that particle system and use the below code.

var explosionEffect : GameObject; //Set it to your prefab in inspector

function OnTriggerEnter(){ Instantiate(explosionEffect, transform.position, Quaternion.identity); }
