Exclude Joystick's Area from Input.touch

Question

Hi, Im trying to make a Sidescroller-Shooter Game, using the pregiven Sidescroller controll prefab from Unity. I got my player aiming at the point, where i touch the screen.

 function Guncontroll() {
 
     if(Input.touchCount > 0){
     var i : Vector2 = Input.GetTouch(0).position;    
 
     aimpoint.position = playercamera.ScreenToWorldPoint(Vector3 (i.x, i.y, 10));
 
     gun.LookAt(aimpoint);
     
 
 }
 }

Now i want to exclude the Joystick Areas (Bottom right corner & and bottom left) from that, so, that the player doesn't aim at the Joystick, as I start to walk.

Hope someone could help me :)

Found the solution myself. You need to acces the "lastFingerId" from the touchpad and check, that it is not the fingerId of the touch you want to controll the character with.

 function Guncontroll() {
 
 
     if(Input.touchCount > 0 && Input.GetTouch(0).fingerId != moveTouchPad.lastFingerId){
     var i : Vector2 = Input.GetTouch(0).position;
 
     aimpoint.position = playercamera.ScreenToWorldPoint(Vector3 (i.x, i.y, 10));
 
     gun.LookAt(aimpoint);
     
     
 
 }
     if(Input.touchCount > 1 && Input.GetTouch(0).fingerId == moveTouchPad.lastFingerId){
     var i2 : Vector2 = Input.GetTouch(1).position;
 
     aimpoint.position = playercamera.ScreenToWorldPoint(Vector3 (i2.x, i2.y, 10));
 
     gun.LookAt(aimpoint);
     
     
 
 }
 
 }

It's kinda working, except I have to press the joystick first, then the touch on screen and if I release the touch it snaps back onto the joystick. any help?

Check if your touch is inside the Joystick collider

if you are using some kind of ui cam for the joystick you can use

 function Guncontroll() {
  
 if(Input.touchCount > 0){
 
    var ray : Ray = UICam.ScreenPointToRay(Vector3(Input.GetTouch(0).position.x, Input.GetTouch(0).position.y, 0));
    var $$anonymous$$t : RaycastHit;
    if(Physics.Raycast(ray, out $$anonymous$$t, Mathf.Infinity, LayerMask.NameToLayer("UILayer")))
    {
        if(Input.touchCount > 1)
           var i : Vector2 = Input.GetTouch(1).position;
        else
           return;
    }
    else
        var i : Vector2 = Input.GetTouch(0).position;
  
    aimpoint.position = playercamera.ScreenToWorldPoint(Vector3 (i.x, i.y, 10));
  
    gun.LookAt(aimpoint);
  
  
    }
 }

Make sure to set the UICam variable to the ui camera.

T$$anonymous$$s is converted from C# ;)

hope it helps

Your var i contains the Input.GetTouch(0).position right? So if you know the area of the joystick, you should be able to prevent your gun from pointing towards the joystick area.

somt$$anonymous$$ng like : function Guncontroll() {

 var joyStickAreaMin:Vector2 = new Vector2(0,0);
 var joyStickAreaMax:Vector2 = new Vector2(10,10);
 
 if(Input.touchCount > 0){    
 var iX : float = Input.GetTouch(0).position.x;
 var iY : float = Input.GetTouch(0).position.y; 
 if((iX <= joyStickAreaMin.x && iX >= joyStickAreaMax.x) && (iY <= joyStickAreaMin.y && iY >= joyStickAreaMax.y)){
 aimpoint.position = playercamera.ScreenToWorldPoint(Vector3 (i.x, i.y, 10));
 gun.LookAt(aimpoint);
 }
 }
 }
