3D Image Button gadget

[Didaktik]

To build a more or less serious GUI is very necessary Image Button Gadget. In CEGUI does not. So as CEGUI does not track clicks on a lot of gadgets, such as ImageGadget.

There are some ways to fix it?

Hi Didaktik
if you can't find a 3D Image Button gadget, then i suggest to use the 3D objects as buttons (spheres, cubes, ...). we only picked the body of the object, then we will know its name, then we add code .

Code: Select all

If ExamineMouse()
        MouseX = -MouseDeltaX() * #CameraSpeed * 0.05
        MouseY = -MouseDeltaY() * #CameraSpeed * 0.05
        InputEvent3D(MouseX(), MouseY(),0)
        
        ent = BodyPick(CameraID(0), MouseButton(#PB_MouseButton_Left), MouseX(), MouseY(), 1)
        If ent = 3
          Sleep_(200)
          x.f+1:y.f=0: ScrollMaterial(3,x,y,#PB_Material_Animated)
          x=0
          rotate ! 1
          
         ElseIf ent = 2: Debug "ok"
                
        EndIf
        
 EndIf

we must use sleep_(200) or what is suitable for the system.
but i prefer if there is MouseUp function , since MouseButton can have many moments while pressing the Button.

suitable for static scenes, but for a movable scenes we must reposition these Buttons, haven't tried it.

needs PB 5.50 (for the BodyPick() function
press the Sphere Button to toggle ON/OFF rotation of the graphics shape,

;I very seldom use the CEGUI and normally stick to sprites only.
;Anyway, here's a very simple approach, which uses the ImageGadget3D()
;as an ImageButton.
;You need to use LoadTexture() for each image. You can't do a CreateImage()
;and then a CreateTexture() -  and then assign it to the gadget.
;If you create your images with code, you must save them and then reload using LoadTexture().
;Remember to use Add3DArchive(Path,Type) to point to the location of the images you wish to use.

DK_PETER, thx!

But this code not work in ScrollAread3D. And it will be very difficult to alter it for ScrollArea.

Faced the same problem. Requires either "ImageButtonGadget3d" or event tracking (click) on ImageGadget3d
