C# script won't give me the Debug.Log message

This script is to be placed on an empty game object with a sphere collider marked as trigger infront of an arcade machine.

using UnityEngine;
using System.Collections;

public class ArcadeMachine : MonoBehaviour 
{
	public GUIText playGame;
	private GameObject player;

	void Awake() 
	{
		player = GameObject.FindGameObjectWithTag("Player");
		playGame.text = "Press 'P' to play!";
	}

	void Start() 
	{
		playGame.enabled = false;
	}

	void OnTriggerEnter(Collider other) 
	{
		if(other.gameObject == player) 
		{
			playGame.enabled = true;
		}
		if(Input.GetKeyUp(KeyCode.P)) 
		{
			Debug.Log("Playing Game");
		}
	}

	void OnTriggerExit(Collider other) 
	{
		if(other.gameObject == player) 
		{
			playGame.enabled = false;
		}
	}
}

I just want a message to return, letting me know that everything is working,as a a filler until I can set up the desired code. I get the “Press P to play” GUI, which disappears once I exit the collider, but once I am within the collider, and press P, I get no message in the console. Does anyone know how to fix this?

OnTriggerEnter is called only once, when the collision occurs. To log the message to the console, you would actually need to be releasing the P key AT THE SAME FRAME than the collision occurs.

Fortunately, you have a MonoBehaviour callback called OnTriggerStay(Collider other)
If you put your input check inside this function, everything should work fine
