Hey guys! I'm working on a scrollable menu and I'm using "destination out" blend mode to contain the items. The problem is they are still clickable in the "destination out" zone. I want the items to be only clickable when they are inside my modal.

This is the closest answer I found. Unfortunately, the example is no longer downloadable.

The easiest way is to check if the touched object (button) is in the visible area, by comparing its Y coordinate. Or you can add a condition "Button is not overlapping Mask object".

These do not work because they make the inside objects not clickable. Let's say an object is 2/3 shown and 1/3 hidden then it's 100% not clickable which make it seems like a bug ...

You need to set the correct Y range in which you want your buttons to be clickable, or adjust collision polygons on the mask sprite.

For example, if your buttons have origin image point in the center, compare that their Y position is inside these red lines.

Thank you! This works partially but it is fine for now.

The reason is that no matter how I set the image point (top, center or bottom) there will always be a small area that is clickable beyond modal. I could make the top & bottom paddings bigger to fill the gap but that would make add a lot of extra negative space. I don't think there's a way around this unfortunately :(

You can add another condition checking that Touch.Y is also within those two Y values. This way players will not be able to tap on an invisible part of the icon.
