    Hey,

    I created a cube in my 3D World in Unity (5). When I add a script, with one of the two functions OnMouseDown and OnMouseOver the function is called when I click the cube or go over it with the mouse. The problem is that, when I create a raw image in my canvas and add the same script, the functions are not called when I click.Please help me. Thanks in advance and sorry for my bad english.

    The OnMouseDown and OnMouseOver functions do not work in the UI system. The EventTrigger system will give you what you need.

    Okay Thanks! With the EventTrigger I can call a function, when I just go over the image. But how can I make it, that the function is called again and again while the mouse is over the image. With MouseEnter it only gets called once.

    I got it. I have the methods OnPointerDown and OnPointerUp where I change the bool clicked to true and to false. And in update method I move the player while clicked is true.

    Just a necro to report that the code comments for OnMouseXXX callbacks says that it's working for Colliders ... and GUIElements (which has been removed since Unity 2019.3), it's confusing as one could think that it's working on UI, but it's not.
    Maybe it's time to clarify it directly into the code comment.
