How to Run OnPaticleCollision ?

Hi,

I have particle effect prefabs and i instantiate one of them at the position of Player in my game. What i try to do is when i set active instantiated particle prefab true, enemies will be destroyed that on collision with particle effect.

Everything else work well except particle collision. I have no idea how to get it work. I shared images of inspector and how it looks in scene. I also shared my script. Can anyone help me to get it work ?

(Note: The script attached to Player.)

Thanks…

public void OnParticleCollision(GameObject other)
    {
        if (other.gameObject.tag == "Enemy")
        {
            Destroy(other.gameObject);
        }
    }

What you have posted looks correct.
Try adding a Debug.Log to the function to see if it runs at all? Maybe the tag == “Enemy” line is wrong?

I instantiate 3d effect at the position of 2d sprite and enemies are 2d sprites too. Is this the reason that it’s not working ?
I put a 3d cube which has collider and enemy layer, on the scene and tried again. It’s still not working. Is using OverlapCircle2d more advanced for me ? Since i couldn’t get it work, ive to find any else way to move on. :confused:

To collide with 2d sprites you’ll need to set the collision module to 2d mode.

But not sure why it’s not working even with a 3D cube for you.

Also, what did you find out based on my first reply? Is the function being called at all?

Yes i have tried the way you said and nothing appears in console when test it by Debug.Log. I don’t know why. Maybe i put the script in wrong object.

All in all, i used overlapCircle2d and set its radius by same value effect’s scale has. Now it’s working the way i want. I’d like to move on with particleCollision method though. Thanks.

You can use the script on either the Particle System or the collider.
