Question by Jtrobinson · Jan 04, 2019 at 01:10 AM · script.particlescolliderstriggerscollisions

How to make a particle system play on trigger with another box collider

Basically, the player runs into the coin. Both the coin and the player have a box collider. The particle system should play when the player hits the coins box collider.

Yet I don't know how to do this because the coins are attached to obstacles (prefabs) that randomly generate off the screen and eventually move on screen towards the player.

Here's what I have so far in the inspector, I've looked at tutorials all of which fail to give up to date advice. Any help is appreciated.

Is the coin collider's isTrigger set to true? If not set it to true, it should work. If yes, create a simple script to execute the ParticleSystem when the player hits the coin.

 //declare your particle system here
 
 void OnTriggerEnter (collider other)
 {
     ParticleSystem.Play()
 }

Ok, so I declared a public particle system and inputted the coin particle system into the inspector. Here is the code

Now that I did that I'm getting an error saying particle system is not attached to a player yet my playscript is trying to reference it. I don't understand this because the player shouldn't need a particle system to activate the coins particle system?

When I attach a particle system to the player it works how it's supposed to, This isn't a lasting solution because the player can't have a particle system in my game.
