How to trigger a specific collider ?

Questions & Answers

Hi, I’m new to Unity and C#.

I’m trying to use “OnTrigger” for detecting if the player enters the trigger Polygon Collider of the Enemy. But, It’s checking for Box Collider.

Please help

private void OnTriggerEnter2D(Collider2D other) {
        Health playerHealth = other.GetComponent<Health>();

        if(playerHealth != null) {
            playerHealth.LoseLife();
        }
    }

Should I use OnCollision2d()? If yes, then how to specify the colliders?

You might not want to trigger specific collider type (for good structure), but you can make collider child object with specific component and attach them to your player.

For example:

On Your Player Scene Hierarchy:

Player

-----Collider1 GameObject (Attached Script: Collider1Behaviour)

-----Collider2 GameObject (Attached Script: Collider1Behaviour)

On Enemy Collider Script:

  private void OnTriggerEnter2D(Collider2D other) 
            {
                if(other.GetComponent<Collider1Behaviour>()!=null)
                {
                    //Do Something
                }
            }
