Title: Detecting Mouse/Touch Drag Over
Post by: kennethljj on February 13, 2014, 04:42:56 AM: Hi All,

I have 3 instances of a cube next to each other, each contains the same script and a colldier, basically a clone of a prefab. (eg. cube A, B and C)
I would like to start dragging at cube A, drag pass cube B and over to cube C. (The cubes does not move, I just need the mouse/touch collider event)
When dragging over cube B, I would like to flag a boolean for the scipt attached to cube B and do the same when I drag over cube C as well. Let's say "isCollided = true;"

I have managed to use OnDrag to capture the start of the dragging event but was unable to capture the collision of the rest of the cubes.

Sorry for the poor english and explanation. Hope someone can help.

Thanks in advance.

Hi Aren, thanks for the reply.
I did a Debug.Log for both OnDragOver and OnDragOut but it didn't work as expected.
The debug message was not printed when i drag across the objects in and out of the colliders.

Hi Aren, Thanks again for the reply. I am not dragging any object across the screen. I just simply want to detect mouse drag over/ touch drag over.

I have 3 objects will colliders and the same script which contains OnDragOver and etc. If any of those events occur, I issue a Debug.Log print message. However, when I start dragging from 1 object to another, I do not receive the 2nd or 3rd objects' events. Like you mentioned, do I need to disable the 1st object's collider to make this work?
