Running code when the player clicks anywhere BUT on a button

Hello all,

On my main menu I want the player to be able to start the game by pressing anywhere on the screen except for on buttons like "options" and "info". I was using EventSystemManager.currentSystem.IsPointerOverEventSystemObject () to try to ignore clicks on buttons, but I then ran into the problem that the clicks didn't go through text elements either. How would I do this?

Additionally, I am attaching an empty GameObject to the Canvas with a script that handles this logic while the main menu is active. Is there a way to do all of this without having to attach an empty GameObject to the UI?

 

Well, in essence what you're proposing kind of is just a giant, invisible button though. Is there any particular reason you don't like going this route?

 

This seems like it may be best accomplished with regular old scripting.

Have a boolean set to "gameOn = false" or something, and then wait for a touch. If the touch is on a button, ignore it (disable the button interactivity until the game starts), but if the touch isn't on a button, do some start game function.

 

Try attaching IgnoreRaycast.cs script to the Text elements to prevent it from catching the clicks. The script is from the UI Example Project.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4.  
5. public class IgnoreRaycast : MonoBehaviour, ICanvasRaycastFilter
6. {
7.     public bool IsRaycastLocationValid(Vector2 sp, Camera eventCamera)
8.     {
9.         return false;
10.     }
11. }
