Show a name of a UI object

Unity Engine
1

When I hover over an UI object (Image) I want to get its name. How do I do it?

This code doesn’t seem to work:

function FixedUpdate () {

var hit : RaycastHit2D = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);

if(hit.collider != null)
{
    infoTD.text = hit.collider.gameObject.name.ToString();
}
}

physics raycasters don’t interact with the UI. Event system raycasters do

Also, is your GUI component located in the scene, otherwise it isn’t in world coordinates.

What you’re trying to accomplish is much easier to do if you use add an Event Trigger to your Image.

pointer enter and exit events

(they really need some better content in those docs though :eyes: )
