Using two trigger colliders

Questions & Answers
1

As the title says, I am needing help with two trigger colliders. I am creating a co-operative puzzle game about two cubes, a big cube and a small cube. In this game I am creating a turret that finds and shoots the cube. However, I want the big cube to be detected anywhere around the turret in a circular range (currently working) and the small cube to only be detected in a smaller cube range in front of the turret (not working).
In a sentence, my problem is I am trying to get input from the different triggers separately, and currently just using OnTriggerStay/Enter/Exit only detects the big circle collider (as it is the biggest).
Here is a picture if it helps. Notice the big collider, then the small one.

Thank you if you can help, and sorry if my explanation is a little vague, also I work in C# but java is fine if that is all you know.
I already made some code for detecting the big cube, as seen below, but I need a way to detect them separately. (I have edited it a bit to show you more or less how the small cube should function.)

public Transform target;
public Transform target1;
public GameObject barrel;
public bool inrange;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update() {

}

void OnTriggerEnter(Collider other) {
	if (other.tag == "Player1") {
		inrange = true;
		barrel.particleSystem.Play ();
	}

	if (other.tag == "Player2") {
		inrange = true;
		barrel.particleSystem.Play ();
	}
}

void OnTriggerStay(Collider other) {
	if (other.tag == "Player1") {
		transform.LookAt (target);
	}

	if (other.tag == "Player2") {
		transform.LookAt (target);
	}
}

void OnTriggerExit(Collider other) {
	inrange = false;
}

}

As far as i know you can’t get data about what trigger triggered the action, and it’s not recommended to use more than 1 trigger on one gameObject.

However there is a workaround:

You may attach your triggers to 2 child gameObject of your turret.
Then make a simple script wich onCollisionEnter will call custom function of your turret script with 2 params, the object that calling this function and Collider information that has triggered it.

This should work, but you want to modify it for you:

Here i assuming that children gameObjects is named TriggerRound and TriggerFront.

// on child gameObject with trigger

public class TurretChildScript : MonoBehaviour {
	private TurretScript parentScript;
	void Start(){
		parentScript = transform.parent.GetComponent<TurretScript>();
	}
	void OnTriggerEnter(Collider other){
		parentScript.recieveTriggerEnter (name, other);
	}
}

//and on parent gameobject (turret):

public class TurretScript : MonoBehaviour {

	public void recieveTriggerEnter(string fromObject, Collider other){
		if(fromObject == "TriggerRound"){
			if (other.tag == "Player1") {
				transform.LookAt(other.transform);
				Debug.Log(fromObject);
			}
		}
		if(fromObject == "TriggerFront"){
			if (other.tag == "Player2") {
				transform.LookAt(other.transform);
				Debug.Log(fromObject);
			}
		}
	}	

}

If you want OnTriggerStay or OnTriggerExit, you can add it in both scripts
