OnDragDropRelease Error?

[sawada]

hi i am use　Automatic translation,sorry

create splite and Attach Colider And Script,
this Script Extend [UIDragDropItem] and Use [OnDragDropRelease]


The [OnDragDropRelease] code is

protected override void OnDragDropRelease (GameObject surface)
{
if(surface.gameObject.name == this.gameObject.name){
   Debug.Log("why?");
}
Debug.Log("name " + surface.gameObject.name);
   }

In this state
drag splite,but　may be Call "why" Log.

For example
drag at place without anything ,
drag at ather name ather splite,

This is what. 

At what kind of time GameObject surface　is Oneself　splite

i use ngui [Version 3.0.8 f7]

Happens when you don't disable the object's collider. The collider of the object you're dragging must be disabled when the dragging operation begins. Look inside UIDragDropItem.OnDragDropStart function:

1.                 // Disable the collider so that it doesn't intercept events
2.                 if (mCollider != null) mCollider.enabled = false;

I'm guessing you overrode that function and forgot to call that base.OnDragDropStart.

thanks ArenMook,

I look OnDragDropStart,
And Write Under Code

1.         protected virtual void OnDragDropStart ()
2.         {
3.                 // Automatically disable the scroll view
4.                 if (mDragScrollView != null) mDragScrollView.enabled = false;
5.                
6.                 // Disable the collider so that it doesn't intercept events
7.                 if (mCollider != null) mCollider.enabled = false;
8.         }
9.  

and

1.         protected override void OnDragDropRelease (GameObject surface)
2.         {      
3.                 if (mCollider != null) mCollider.enabled = true;
4.  
5.                 if(surface.gameObject.name == this.gameObject.name){
6.                         Debug.Log("why?");
7.                 }
8.                 Debug.Log("name " + surface.gameObject.name);
9. }
10.  

Start Test,
Drag Sprite so collider is don't disable,
Release Sprite collider is change disable,

but Drop othert splite so Call "why" Log
this problem is not unresolved

I get advice agein?

Then you need to investigate further. If the collider is disabled, then it should not be physically possible for it to receive events or get picked up by the UICamera. Yet it seems to get picked up. You'll need to investigate why it happens in your case.

As you can see this doesn't occur in the provided drag & drop example.

P.S. Also... why are you comparing names? You shouldn't compare names. Compare game objects.

thanks ArenMook.
I will investigate more.
Reports Once you know what.

thanks a lot
