Hi,

I am interested in doing a highly customized screen appearance as opposed to the screens which the BB provides. So I was wondering if anyone has sample code for a game on the BB - as games almost always do interesting things with graphics and UI.

Thanks,
Dallan

try this for starters: meshsystem >> Parallax Scrolling for Blackberry - but move the graphics constructer out of the main loop - god knows why that's done like that.

[dthunt]

Thanks for that. I tried it out.

Do you have any sample code where the game uses a transparent screen with a weird shape. Say I want to do an analog clock which is a circle, and I want it drawn on top of the applications so you can see them. Something like that would be really useful.

nope, never attempted it, are you thinking of having a screen that floats over the homescreen? - not sure that's possible...

[dthunt]

Yes, I was wanting a screen which floated on top of all other screens at all times in fact. On which the user could interact with and send events to applications in the background.

i could be wrong but i dont think that's going to be possible.

While I don't believe you can have a transparent Screen object on top of a background one, you can try creating a function that simply draws transparent icons on top of the current screen. The blackberry JDE has a CustomButtons example for making circular or specialized buttons. For transparency, include

graphics.setGlobalAlpha(90); // lower number => more transparent

before performing any draw operation.

This will make drawn pic files as transparent yes, but what is in the background will be a plain color like white or something - instead of the background images running.

'images' should be 'applications' in the last post

[Californium]

You can draw the background image for the application first and then draw the transparent pictures on top.

I've attached a simple program that demonstrates this method. A circle moves back and forth across the screen. Three transparent buttons are in the upperleft corner. Press 'ESC' to quit the program.

With this method, you need to redraw the transparent objects for each screen but it should hopefully provide the desired effect.

Wow Californium, wonderful app

[jfisher]

i think you're completely missing the point of what the original poster was after, i was under the impression he wanted to have a floating application that sat on top of the homescreen icons.

[dthunt]

Yea, something to that effect.

[Californium]

Ah, my mistake. I thought you simply wanted transparencies within an application with multiple screens.

For something that hovers over the homescreen and every application, I do not believe that's possible.

What about a program that just shows the background (not to hover over all apps). I was thinking about writing a new lock program that doesn't have that silly "Call Emergency Button" on it and wanted it to look like the normal lock app.

Thanks,

Brad

Edit: Nevermind, I found out the mute button does what I want. Thanks anyway though.
