How to disable the GUI on a second camera

[gavindi]

Hi all,

I'm using a 3D GUI in my little project that I only want to be displayed on Camera 0. My second camera (1) shouldn't display the GUI at all as it's used as a top-down map view of the playfield.
Currently, I have:

Code: Select all

ShowGUI(32, #False,0,#True)
ShowGUI(255, #False,1,#False)

My understanding is that the third parameter that state camera 1 will be disabled by #False in the fourth parameter, but it isn't working for me.

My work-around is to use:

Code: Select all

ShowGUI(32, #False,0,#True)
ShowGUI(0, #False,1,#False)

which uses the first parameter to set full transparency of the GUI.
I would rather disable the GUI completely on the second camera as I expect that this would save me a few rendering cycles.

Any ideas anyone? Please?

Cheers,
G.

It works fine here.

Just added a camera in Window3D.pb example :

Hey,

That's really odd. Your example works as expected and it's a very simple thing to code. SO simple, I must be overlooking something but for the life of me, I can't see why it isn't working in my code. I tried mangling your example to break it and I can't so what the hell am I overlooking?!

Here's my two procedures, the first is camera set-up and second for the GUI:

Code: Select all

Procedure PositionGameCamera()
; Create & Position Camera
; ------------------------------------------------------------
	CreateCamera(0,0,0,100,100)
	MoveCamera(0,5,5,20,#PB_Absolute)

	CameraLookAt(0,5,0,5)
	CameraBackColor(0,$c08000)
	
	CreateCamera(1,45,83,10,15)
	MoveCamera(1,5,14,5,#PB_Absolute)
	RotateCamera(1,-90,0,0)

	CreateLight(0,$ffffff,5,5,11)
EndProcedure

and

Code: Select all

Procedure InitInGameGUI(*ptr.MediaStruct, Array Hero.Player(1))
	OpenWindow3D(0, 10, 10, 200, 100, "Player 1",#PB_Window3D_Borderless)
	ProgressBarGadget3D(0,10,35,180,20,0,7)
	TextGadget3D(4,10,5,70,30,"Health")
	
	OpenWindow3D(1, *ptr\ScreenWidth-210, 10, 200, 100, "Player 2",#PB_Window3D_Borderless)
	ProgressBarGadget3D(1,10,35,180,20,0,7)
	TextGadget3D(5,10,5,70,30,"Health")
	
	OpenWindow3D(2, 10, *ptr\ScreenHeight-110, 200, 100, "Player 3",#PB_Window3D_Borderless)
	ProgressBarGadget3D(2,10,35,180,20,0,7)
	TextGadget3D(6,10,5,70,30,"Health")
	
	OpenWindow3D(3, *ptr\ScreenWidth-210, *ptr\ScreenHeight-110, 200, 100, "Player 4",#PB_Window3D_Borderless)
	ProgressBarGadget3D(3,10,35,180,20,0,7)
	TextGadget3D(7,10,5,70,30,"Health")
	
	ButtonGadget3D(20, 90, 70, 100, 25, "Quit")
	
	;ShowGUI(192, #False,0,#True)
													; Need to find out how to properly disable the GUI
													; on Camera 1. Currently using the transparency value
													; to effectively hide the GUI from this camera
	ShowGUI(192, #False,1,#False)
EndProcedure

Hi Again,

I thought I'd show how I also mangled your example since it's also having a strange side-affect now. I'm trying to tell it to show the mouse pointer on camera 0 only and now there is no mouse at all on either camera:

You have one mouse cursor For a screen, set the parameter 'ShowMouseCursor' With the same value

Code: Select all

    ShowGUI(128, #True, 0, #True)
    ShowGUI(128, #True, 1, #False)
