Displaying text on trigger enter
Hello everyone, I have a question for you all today. I have been trying to display some text telling a player to turn back or be killed so that they don't fall off the map, but I am having some trouble actually displaying it on the screen. My code so far is as follows:
using UnityEngine;
using System.Collections;
public class Boundaries : MonoBehaviour
{
//Declaring variables
bool crossedBoundary;
void OnTriggerEnter(Collider other)
{
//Telling game to actiavte boolean
if(other.gameObject.tag == "Player")
{
crossedBoundary = true;
}
}
void OnGUI ()
{
//If the boolean is active, display the text
if (crossedBoundary == true)
{
GUI.Label(Rect(200, 100, 0, 0), "Turn back or die!");
}
}
}
Another tip while we're here, you only need to write the name of the bool, to check if true. Like this:
if (crossedBoundary)
{
dostuff();
}
And just use an ! if you want it to check if not true. (!crossedBoundary).
Well, one clear issue is that you forgot to put "new" before the "Rect" call. It should be:
GUI.Label(new Rect(200, 100, 0, 0), "Turn back or die!");
Also, make sure you have the player object tagged as Player.
Thanks, I'll try this as soon as I have time. While you guys are still here, what would you recommend I do for the countdown timer until the Player actually dies? I've heard something about coroutines, but I don't really understand what they are. Again, thanks for your help (can't believe one word caused me to stay up for 2 hours trying to figure out what was wrong with my script!)
Coroutines run separate from the Update function, and in them, you can declare Wait times, such as "`yield return new WaitForSeconds(10.0f);`". You'd set up a coroutine by making a new method in your script, starting with "IEnumerator" then "name you want" and () encapsulation. So:
IEnumerator playerWait(){
do stuff;
yield return new WaitForSeconds(10.0f);
do more stuff;
}
It has a lot of uses. I'd suggest reading up more on them :)

(Oh, and you'd initiate the Coroutine from somewhere else in your script, when you wanted to, with StartCoroutine(playerWait()); Assu$$anonymous$$g your coroutine was named "playerWait".)
