How do i merge these things?
Hey, everyone! i'm working on a talking system, for a tutorial level. The aim is to activate the GUI elements in the script when you touch a cube with is trigger on. the script however right now, consists of two parts that need to be one: the part where the trigger outputs an action, and the part with the actual GUI:
public var text = "box text here";
public var NPCname = "NPC name here";
function OnTriggerEnter (other : Collider) {
print ("Test");
}
function Start () {
}
function OnGUI() {
GUI.Box(Rect(Screen.width / 6,Screen.height / 1.3,Screen.width / 1.5,Screen.height / 4),"Test 2");
}
Now, the first part makes the log print Test, that works fine, so we've got a working trigger. the second part is the setup for the GUI itself. my question is, what string of code allows me to have the trigger activate the GUI?
I strongly advice you do some tutorials to get the basics of programming, and learn what kinds of commands and variables are available to use.
Use a boolean that changes state based on if an object is in the trigger zone
var inTriggerZone : boolean = false;
function OnTriggerEnter (other : Collider) {
inTriggerZone = true;
}
function OnTriggerExit (other : Collider) {
inTriggerZone = false;
}
function OnGUI() {
if ( inTriggerZone ) // this is the same as writing if(inTriggerZone==true)
{
GUI.Box(Rect(Screen.width / 6,Screen.height / 1.3,Screen.width / 1.5,Screen.height / 4),"Test 2");
}
}

Thanks, i am following tutorials, and i tried to write up some code from scratch myself as an exercise, but i couldn't find a tutorial for this specific thing... are you ok with it if i use this code?
Yes of course, this was an example written for you.
The next thing to check would be what entered the trigger. Check an objects name :
function OnTriggerEnter (other : Collider) {
Debug.Log( other.gameObject.name + " has just entered the trigger" );
if ( other.gameObject.name == "Player" ) // did an object named Player enter the trigger?
{
inTriggerZone = true;
}
}
you can use tags :
if ( other.gameObject.tag == "Player" )
It all starts from here. Happy Coding =]
