Hello, all I’m trying to do is detect if the sprite rectangle contains the mouse position however I have no idea how to get access to a Sprite gameObject’s rectangle. I have the same effect working with GUIText but would like to make this work to make a menu using sprites as buttons.
The only way for this to work, apart from making sure there is Collider component, is to make sure the Z index of the object is on top, even if you are making 2D games. The sorting layer is ignored and Z index take precedence instead.
So this means you may not be able to attach your sprite under another game object. I tried parenting my sprite under another game object and my mouse click is no longer detected.
Add a collider to the game object (preferably 2D) and then call the functions OnMouseDown/Over/Up as @Eric5h5 told you. I want to emphasize that these functions won’t work unless you add a collider component.
