Add Number to GUI when object is collected

Hi

I'm trying to make it so that when I collect an object it adds a one to the counter that I've added using a Game GUI script but I'm not too sure how to do it.

I've tried using this code but it keeps coming up with errors when I try to play my scene:

using UnityEngine;
using System.Collections;

public class GameGUI : MonoBehaviour {

public int counter = 0;
public int timeLeft = 30;
public GUIStyle mystyle;

void OnGUI () {
GUI.Label(new Rect(50,Screen.height-45,100,30), "Collected: "+counter, mystyle);

}
}
void OnTriggerEnter2D (Collider2D obj) {
if(obj.gameObject.tag=="Player"){
+=(1) counter, mystyle}

I've also got code on the objects that I'm collecting so that they destroy themselves when my game character enters their box collider.

Thanks

 

I think it should be:

Code (CSharp):

1. void OnTriggerEnter2D (Collider2D obj) {
2. if(obj.gameObject.tag=="ThingYou'reCollecting"){
3. counter += 1;
4. }

Could even destroy the object in there too:

Code (CSharp):

1. void OnTriggerEnter2D (Collider2D obj) {
2. if(obj.gameObject.tag=="ThingYou'reCollecting"){
3. counter += 1;
4. Destroy(obj);
5. }

 

Hi

Thanks for the help I got it working
