lookAt script for the iPhone

Unity Engine

I have this lookAt script that makes the object look at the mouse, how do I get it to work with touch input though? Basically just when the player is touching the screen I want the object to look toward where he is touching.

	function lookAt(){
	var hit : RaycastHit;
	var ray = Camera.main.ScreenPointToRay (Input.mousePosition);

	if (Physics.Raycast (ray, hit)) 

		{
					transform.LookAt(hit.point);
		} 
	}

if (Input.touchCount > 0){
var touch : Touch = Input.GetTouch(0);

everything else should be fine but Input.mousePosition should be your touch.position instead.

}

tell me how that works

That works perfectly, is there a way to do that with onMouseDown, but for GUI?

you could use OnGUI.
I prefer 3d menus and GUITextures for iPhone myself, here is my script for GUITextures that should answer any more questions

//uses GUITextures and put this script on each texture in the menu system. be sure they are in sync and test often.
var activate : GameObject[];
var deactivate : GameObject[];
var Deactivate : boolean=true;
var Activate : boolean=true;
var StartLevel : boolean=false; //
var begin : boolean=true; //does it start activated

function Start (){
	
	guiTexture.pixelInset = Rect(guiTexture.pixelInset.x * Screen.height/320, guiTexture.pixelInset.y * Screen.height/320, guiTexture.pixelInset.width * Screen.height/320, guiTexture.pixelInset.height * Screen.height/320);
	
	if (!begin){
	gameObject.active = false;	
	}
}


function Update (){
	
	if(Input.touchCount > 0){
    var touch: Touch = Input.GetTouch(0);
    if(touch.phase == TouchPhase.Began  guiTexture.HitTest(touch.position)){
	print("hit  " + guiTexture.name);
	
	if (Activate){
		for (var ao : GameObject in activate){
		ao.active = true;	
		}
	}
	
	if (Deactivate){
		for (var deo : GameObject in deactivate){
		deo.active = false;	
		}	
	}
	
	
	if (StartLevel){
	Application.LoadLevel (1);	
	}
}}}

edit: OnMouse whatever works in the iPhone simulator but I dont think it works when its built in xcode

I used the same thing basically with one exception:

 var touch: iPhoneTouch = iPhoneInput.touches[0];

What’s the difference between touches and GetTouch?

touches represents how many fingers are touching the screen

I use Input.GetTouch(x) to find the phase and position for each touch

7

Ok thanks, that’s what I thought, but does it matter though if I just care if one finger touches it? I mean will it do the same thing?

8

mmmmm not sure. try it out

Ok thanks. Right now I actually don’t even have the iPhone version of Unity (because I’m on a PC) so I’ll test it when I get a Mac. Thanks for all your help.
