Use 2d Polygon Collider to detect OnMouseEnter on UI

Questions & Answers
1

I have a UI image that is a triangle, and while the image is a box of course I need to only detect OnMouseEnter on the triangular area. However I cannot get this to work. I have tried adding a PolygonCollider2D to my Image and set it to isTrigger = true, but I cannot get it to log anything! Any help is appreciated!

I made the collider a bit bigger so you can see it

My code is attached to the Image with the PolygonCollider2D and right now is very simple, but is not logging anything:

void OnMouseEnter()
{
    Debug.Log("Collider Entered!");
 }

Is the code you provided located within the Radial Button script? Is the script where this code resides even attached to the game object which owns the polygon collider?
