OnPointerExit repeatedly calls during drag operation.

I have 2 image objects in my project and I want to drag one over the other. When I drag object 1 over object 2 I use OnPointerEnter to increase the alpha of object 2 and OnPointerExit to decrease it again.

Testing shows that OnPointerExit keeps firing despite the mouse not exiting the bounds of the target object. I'm getting one OnPointerExit for between every two and five 'OnDrag's.

Before I spend ages stripping out all the extra code on an extensive bug hunting mission, I'm wondering if there's something well-known or obvious I'm missing.

 

maybe the ray of the PointerExit gets interrupted while Dragging, how are you dragging the objects?

 

Doh! Thank you for that, it was one of the first things I looked at, 6 hours ago (I remembered watching

21m30 recently) - but then I got sidetracked and completely forgot about it :-(

Code (CSharp):

1. GetComponent<CanvasGroup>().blocksRaycasts = false;

in BeginDrag and

Code (CSharp):

1. GetComponent<CanvasGroup>().blocksRaycasts = true;

in EndDrag solved it.

Double Doh!
