Detecting if there are no touch inputs on only one side of the screen?

Unity Engine
1

I have the script pretty much done, there are probably redundant things in the script but I’m new to unity and not really concerned with the most efficient way to do things (at least not yet), the problem is at the bottom of the code, hopefully you can help me out.

It needs to be able to handle left and right inputs independent of each other, because I’m trying to do a twin stick shooter type thing.

Thanks in advance! :smile:

var fingerDown : boolean = false;
var startPos : Vector2;
var fingerMoved : boolean = false;

var direction : Vector2;
var directionNormal : Vector3;
var directionRot : Vector2;
var directionSpeed : float;

var player : GameObject;
var maxSpeed : float = 5;

var touchAmount;

function Update () { //Preface: using the word touch as a noun is funny and creepy at the same time
	for(var i=0 ; i<Input.touchCount  Input.GetTouch(i).position.x < Screen.width/2 ; i++){ //if there is at least one touch on the LEFT of the screen
		if(!fingerDown){ //if this is a new touch
			startPos = Input.GetTouch(i).position; //save the position
			fingerDown = true; //all touches after arn't new
			Debug.Log("touch down.");
		} else { //if there this is NOT a new touch
			if(TouchPhase.Moved){ //if the finger moved
				fingerMoved = true; //save that for later maybe
				direction = Input.GetTouch(i).position - startPos; //get the vector
				directionSpeed = Mathf.Clamp(direction.magnitude,-maxSpeed,maxSpeed); //and speed of the vector
				directionRot = direction.normalized; //and rotation of the vector
				directionNormal = Vector3(directionRot.x,0,directionRot.y) * directionSpeed; //save a variable for movement stuff
				Debug.DrawRay(player.transform.position,directionNormal,Color.blue);
			}
		}
	}
	[I DONT KNOW WHAT TO PUT HERE]{ //if there is no touch on the LEFT side of the screen
		fingerDown = false; //reset the variable
		fingerMoved = false; //reset this variable too
		Debug.Log("touch up.");
	}	
}

Ok, I figured it out. It basically involves angrily interrogating the amount and position of inputs on screen until you have exhausted all possible variables. Here is the code I’m using if anyone has a similar problem. if you have a better solution please post it

var fingerDown : boolean = false;
var startPos : Vector2;
var fingerMoved : boolean = false;

var direction : Vector2;
var directionNormal : Vector3;
var directionRot : Vector2;
var directionSpeed : float;

var player : GameObject;
var maxSpeed : float = 5;

var touchAmount;

function Update () { //Preface: using the word touch as a noun is funny and creepy at the same time
	for(var i=0 ; i<Input.touchCount ; i++){ //for as long as there are >0 fingers on screen
		if(Input.GetTouch(i).position.x < Screen.width/2){ //if the finger is on the LEFT
			if(!fingerDown){ //if this is a new touch
				startPos = Input.GetTouch(i).position; //save the position
				fingerDown = true; //all touches after arn't new
				Debug.Log("touch down.");
			} else { //if there this is NOT a new touch
				if(TouchPhase.Moved){ //if the finger moved
					fingerMoved = true; //save that for later maybe
					direction = Input.GetTouch(i).position - startPos; //get the vector
					directionSpeed = Mathf.Clamp(direction.magnitude,-maxSpeed,maxSpeed); //and speed of the vector
					directionRot = direction.normalized; //and rotation of the vector
					directionNormal = Vector3(directionRot.x,0,directionRot.y) * directionSpeed; //save a variable for movement stuff
					Debug.DrawRay(player.transform.position,directionNormal,Color.blue);
				}
			}
		}
		if(Input.GetTouch(i).position.x > Screen.width/2  Input.touchCount <= 1  fingerDown){ //if the touch is on the RIGHT and it's the only touch AND theres variables saved
			fingerDown = false; //reset this variable
			fingerMoved = false; //reset this variable too
			Debug.Log("touch up.");
		}
	} 
	if(Input.touchCount <= 0  fingerDown){ //if there are no touches
		fingerDown = false; //reset this variable
		fingerMoved = false; //reset this variable too
		Debug.Log("touch up.");
	}		
}
