Placing a Rect and detecting a Touch/Tap

Questions & Answers
1

Hi guys, I’m in the progress of creating my first 2D Game.

Since I’m both new to Unity and Android development I have some issues with Touch detection.

When I create a Rect with a height of 50px and a width of 100px, it seems as if the Rect is only registering Touch on the leftmost ~10px or so.

Here is my example code:

using UnityEngine;
using System.Collections;

public class StartUpScript : MonoBehaviour {
Rect buttonPLAY = new Rect(80, 340, 100, 50);

// Use this for initialization
	void Start () {}

	// Update is called once per frame
	void Update () {
		if (Input.touchCount > 0) {
				if (buttonPLAY.Contains(Input.GetTouch(0).position)) {
				Application.LoadLevel("GameScreen");
				}
				
		}
}

Also when it works, it feels kinda weird. As if he would fire events more than once or only if you press a certain amount of time. Is there another way to detect a single TAP anywhere on the specified Rect?
As I understand it, “Update” is called once per frame. Might this be the problem?

Thanks for the help :slight_smile:

It might be related to the coordinates of the shape and the touch. Try this:

if (buttonPLAY.Contains(
    Camera.main.ScreenToWorldPoint(
        Input.GetTouch(0).position)) {
...
}
