Question by n4nn31355 · Nov 04, 2016 at 10:25 PM · ui raycast character raycasting ui image

Drag'n'Drop control Image raycast in code.

I want Drag'n'Drop UI Images between Panels. I found few ways to disable raycasting for provide successful call of onDrop event method:

Implement IsRaycastLocationValid method for dragged Image;
Set GetComponent<UnityEngine.UI.Image>().raycastTarget to false in OnDragBeggin method;
Move Image to Layer which ignored by raycast;
Add CanvasGroup component to Image object and change Blocks Raycasts property.

Which cons and pros in this ways?
