OnMouseEnter() function stops working when I set the canvas render mode to: Camera Overlay












1














Basically the title says it all. I have a OnMouseEnter() function that works fine when I have the canvas render mode on Worldspace but stops working when I change it to Camera Overlay.



Before, it would work with just the script with the mouse functions on it attached to the image object. Now to work I need to use an event trigger and add the script to another object to put it into the trigger.



Any idea why?






unity c#

OnMouseEnter is a MonoBehaviour message that's fired by rays cast in the 3D game world (including hit-testing 2D colliders in that 3D game world too).



Once you set your UI to Overlay, it's no longer in the 3D game world. It exists as a pure UI layer painted over-top by a separate pass at the end.



To catch mouse events in this pure UI world, you need to use the UI's event system approach:



public class UIMouseOverExample : MonoBehaviour, IPointerEnterHandler {



    public void OnPointerEnter(PointerEventData eventData)

    {

        // Do your stuff.

    }

}

            Is this a new Fibonacci Identity?

            Image
            6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
