Adding Tooltips?

I'm fairly new to Unity 3d and I'm having trouble adding tooltips for hovering over objects such as buttons. Can anyone help with creating tooltips?

 

(I'm going to assume you are working with Unity 4.6 and the UI system)

Probably the easiest way is to add an EventTrigger component. Add a new listener for OnPointerEnter and OnPointerExit. Drag in the tool tip GameObject. Select the function GameObject.SetActive, and pass in true and false as required.

Note this might not be the best way to add tool tips, but its probably the fastest to get running while you are new.

 

OK Thanks!
