uGUI - on hover?

Is there an onHover event or something like that - or is there another way to detect when a uGUI button is being hovered over?

Yes

  1. Add the component “Event Trigger” to your button.
  2. Add new Event Type
  3. Select “PointerEnter”
  4. Press the “+”.
  5. Add a object with a script attached
  6. Create a public method/function in the script attached to the object.
  7. Assign the Method/function to the Event Trigger. (see image)
