Opening and closing doors

Unity Engine

I can’t find a tutorial that can learn me how to open and close doors when I press F(or any other key).I REALLY NEED HELP.A
I just someone to tell me or link me a tutorial on how to close and open doors.

Try the PlayMaker tutorials. You’ll need to buy a copy of PlayMaker, but it’s probably the easiest way to get started with all this stuff.

Some examples for you to try

If door open/close is keyframed: (And the two animations are named “Open” and “Close”)

//the object with the animation on it
var Door: GameObject;

function OnTriggerEnter(){
Door.animation.Play("Open");
}
function OnTriggerExit(){
Door.animation.Play("Close");
}

^ as simple as that is, it can get broken if you trigger one animation before the other is finished.
Heres an example of a sliding door, or gate, that avoids that:

var gate: Transform;
var gateOpenPosition : float = 2.0;
var gateClosedPosition : float = 0.0;
var gateSpeed : float = 1.0;

var open : boolean = false;

function Start(){
   collider.isTrigger=true;
   renderer.enabled=false;

}

function OnTriggerEnter(other: Collider){
 
   if(other.CompareTag("Player")||other.transform.name==("First Person Controller"))
   {
     open = true;
   }
}

function OnTriggerExit(other: Collider){
 
   if(other.CompareTag("Player")||other.transform.name==("First Person Controller"))
   {
     open = false;
 
   }
}

function Update() {
 

     if(open)
     gate.position.x = Mathf.MoveTowards(gate.position.x, gateOpenPosition, gateSpeed * Time.deltaTime);
 
     else
     gate.position.x = Mathf.MoveTowards(gate.position.x, gateClosedPosition, gateSpeed * Time.deltaTime);
   


}

This final one doesnt need animations either, you have to set the open position yourself (Based on y rotation in the inspector). This is a rotation door open.

Make sure your door objects “center” or pivot point is where a hinge would naturally be. THis only opens once.

var door: Transform;
private var originalPos : float;
//change this as required
var openPos : float=-90;
private var triggered = false;
private var opening = false;
var openingSpeed: float;

function Start(){

origionalPos=door.localEulerAngles.y;

}

function Update () {

if(opening)
{
var angle : float = Mathf.LerpAngle(door.localEulerAngles.y, openPos, openingSpeed);
door.localEulerAngles = Vector3(0, angle, 0);
}

}


function OnTriggerEnter (other : Collider) {

if(other.CompareTag("Player"))
{
//Cleanup
if(triggered)
Destroy(gameObject);

opening=true;
triggered=true;

}

}
