If statement won't work in OnTriggerEnter

Questions & Answers
1

I am trying to say, when the player enters the trigger, the player can press C to go to the next level. Please help

C#

using UnityEngine;
using System.Collections;

using UnityStandardAssets.CrossPlatformInput;
using UnityStandardAssets.Utility;

public class LevelChange : MonoBehaviour {

	public string loadLevel;

	void OnTriggerEnter(Collider other) {
			Time.timeScale = 0;
		if(Input.GetKey(KeyCode.C)){
			Application.LoadLevel (loadLevel);
			Debug.Log("Level loaded: " + loadLevel);
		}

	}
}

Try using OnTriggerStay instead of OnTriggerEnter

Also note: Trigger events are only sent if one of the colliders also has a rigidbody attached.

Input should be called in Update Loop :
http://docs.unity3d.com/ScriptReference/Input.html

using UnityEngine; 
using System.Collections;
using UnityStandardAssets.CrossPlatformInput;
using UnityStandardAssets.Utility;

public class LevelChange: MonoBehaviour {
	
	public string loadLevel;
	bool CanLoad = false;

	void OnTriggerEnter(Collider other) {
		if(other.CompareTag("Player")){
			CanLoad = true;
		}

	}
	void Update(){

		if(CanLoad){
			Time.timeScale = 0;
			if(Input.GetKeyDown(KeyCode.C)){
				Application.LoadLevel (loadLevel);
				Debug.Log("Level loaded: " + loadLevel);
			}
		}
	}
}
