Ok, I have a UIPanel but instead of scrolling it with click and drag, I have a left and right button either side.
I click a button and then I move the scroller in code. Simple eh?
Unfortunately I can't get a click to register with the right button because (as I have found out) that the collider is mixed with the hidden elements in the UIPanel.
In other words all the other elements are obscuring the button collision so clicking there does nothing. If I move the button up above the scroller it works, just doesn't work when in the same axis as the scroller.
Any tips on how to get around this?
