2D Trigger not triggering.
« on: February 24, 2017, 11:08:40 AM »
Looking a the drag and drop demo package, I'm wondering if there is a way to say that a dragged object (any dragged object) is on top of a dropped target?

So, what I want to say is, "there is an object on me" on a dropped target.

I can't seem to get the 2d Trigger to work.

Hi,

Click on "edit" in your colliders, you'll see that they do not match the size of the image or UI elements.

 It's a bad idea to mix 2d colliders and UI elements, they are not supposed to work together, prefer using just the pointer events ( using a pointer component proxy) and then check when pointer enters if a dragging is occuring, something like that.

 Bye,

 Jean

Hi,

  I found the way to do that in a reliable way, with a simple drag and drop component:

It's available in the uGui full proxy on the Ecosystem, the component is called "BoxCollider2dMatchRectTransform"


Bye,
