moving transparent image

[juliuson]

Hi all,

Here is my project, .
I would like to deplace a transparent Image with the mouse.
It works perfectly.

The image (transparent PNG) move only when the user click in a non transparent area.
I precise that I am in 2D mode.
My project is downloadable at the following link :

https://www.developpez.net/forums/d2034797/applications/developpement-2d-3d-jeux/moteurs-jeux-video/unity/deplacements-images-transparentes/#post11300177

All works well.

But if I change the image DragOk (you can find it in the console) by the image DragFalse in the Source Image edit box (you can find it in the inspector),
The problem is that the image is moving even if we click in a transparent area.
What appeals to me is that when rechanging DragFalse by DragOk the program refunction parfaitly.

Awaiting precious help,
A+

I invite you to download my project at the following address (click on ouvrir button in dropbox) :

The problem is that the Image is dragging even if the user click in a transparent area (of the DragFalse UIimage).

The Image must move only if the user click in a non transparent area.
The program works well with the DragOk UIImage (in the Image Source in the Inspector) but not with the DragFalse UIImage.

Thanks for your help,

A+
