I tried many buttons but I can't connect them with the (Java)Script.

So I made 2 gui buttons: one for jump which was easy because I have an if statement and if it's true then jump.

But I have problems with the crouch button. Bellow is my script but I can't figure out how I can do this from Update in function Gui.

(Or if you know how to connect buttons with JS functions, please tell me: it's always a better option :D )

This is my script:

#pragma strict
private var tr: Transform;
private var dist: float; // distance to ground

function Start(){
   tr = transform;  
   var ch:CharacterController = GetComponent(CharacterController);
   dist = ch.height/2; // calculate distance to ground
}

function Update()
{
  var vScale = 1.0;
  if (Input.GetKey("s")){ 
     vScale = 0.5;
  }

  var ultScale = tr.localScale.y;  
  tr.localScale.y = Mathf.Lerp(tr.localScale.y, vScale, 5*Time.deltaTime);
  tr.position.y += dist * (tr.localScale.y-ultScale); 
}

function OnGUI ()
{
  if(GUI.Button(new Rect(15, 330, 200, 100), "Shrink"))
  { 
  }
}

#pragma strict? This is for Unity, right? – Anko Oct 21 at 21:15
    
Yes it is i cant figure out how to put the crouch code in function OnGui – Nikola Pejovski Oct 21 at 22:15
    
I will save you some headache online --- people are rather touchy when it comes to Java / Javascript. In unity it uses Javascript, and modified version at that, so people usually call it Unityscript. Java is absolutely different than Javascript (Java is actually the spiritual father to C# --- which is also used in Unity), and getting Java and Javascript confused is a programming sin online. – return true Oct 22 at 3:09
    
@Anko '#pragma strict' is required for unity when using js. – return true Oct 22 at 3:25

Not sure if this is what you are asking or not, but this is a shot in the dark.

 #pragma strict 
 private var tr: Transform; 
 private var dist: float; // distance to ground

function Start(){
   tr = transform;  
   var ch:CharacterController = GetComponent(CharacterController);
   dist = ch.height/2; // calculate distance to ground
}

function Update()
{
  var vScale = 1.0;
  if (Input.GetKey("s")){ 
     vScale = 0.5;
  }

  //If you are pressing a key, then call crouch
  if(Input.GetKeyUp("c")){
     crouch();
  }

  var ultScale = tr.localScale.y;  
  tr.localScale.y = Mathf.Lerp(tr.localScale.y, vScale, 5*Time.deltaTime);
  tr.position.y += dist * (tr.localScale.y-ultScale); 
}

function OnGUI ()
{
  if(GUI.Button(new Rect(15, 330, 200, 100), "Shrink"))
  { 
        //when this button is pressed call crouch.
        crouch();
  }
}  

function crouch(){
    //make character crouch here
    //this is run once when the "Shrink Button" is pressed.
    //this is also done once when the c button is pressed.
    Debug.Log("Crouch Button Pressed!");
}
