Referencing a collision from another script

Questions & Answers
1

So I want a collision from gameobjects ‘Player’ and ‘Ball’ to effect a variable in my timer script.

Is there a way to detect a collision between two objects on a separate script? I know how to detect a collision if the script is attached to the gameobject directly, but I need my collision detection to be on my timer script so I can effect it’s variables.

public class Timer : MonoBehaviour {

public float timer = 300;
public float timerSpeed = 100;

	void OnGUI () {
		timer -= Time.deltaTime*timerSpeed;
		if (timer > 0)
			guiText.text = timer.ToString("F0");
		else
			guiText.text = "GAME OVER";			
	
	}
	
		void OnCollisionEnter(Collision thecollision){
		
		    if(thecollision.gameObject.name == "Player")
			timerSpeed = 50;
		
	}
}

Anyway this is what I know what to do.

Very new to all this so any help would be most appreciated.

You probably want the OnCollisionEnter function on your Player component. When a collision happens with a gameObject with a Ball component, announce the collision to your gameObject with Timer.

//// In Player.cs

void OnCollisionEnter(Collision thecollision){

  if(thecollision.gameObject.name == "Ball") {
    GameObject.Find("Timer").GetComponent<Timer>().whateverYouWant();
  }
}
