[Coming Soon] Boing Ball Screen Blanker

Here is a "first" alpha shot of the future screen blanker on which I'm workin'on these days :)
It's developed using Amiga OS 4 SDK, MiniGL & AmiDARK Engine (actual private build).

There's no light excepted default ambient but this will change in future :)

EDIT :
Here is a small executable to see the ball moving in 640x480 32bits. Press escape to quit :

I don't know whether you have noticed or not, but AmigaOS 4.1 Update 1 shipped with a Boing Ball screenblanker as standard. It's quite good too :)

@Rigo
animation of this screen blanker is ... saccaded ....
And with latest update ... it does no more work on my Amiga OS 4.1 Sam440Flex 800 computer ...
Mine will come with 3 textures set,and some options (maybe a background, or something else)

@freddix

Make it a fancy one and you have a winner.

I cant watch the picture as there comes some maintance link. same for amidark site

@Kicko

Yes, the ISP is doing some maintenance

This should be fixed tomorrow.

I have added an alternate link ;)

I've added a small executable to test.
Tell me if it's smooth on your config and which config you use ;)

Nice, it works perfectly on my Flex 800, maybe a little darker but very good

It works fine here on my Sam 800.but a little bit to dark

Concerning lights, I know ;)
but as I said upper : "There's no light excepted default ambient but this will change in future :)"
;)

Thank you for your answer.

@freddix

Tested. Works fine and fast :) A bit dark of course, but still pretty neat. I also check included source code: and i think that amidark will be the best demo and game machine for aos4. Functions are much easy that even OpenGL itself.

Only what i noticed (and what imho bad): i can see that for first, it starts in window mode, and after, swith to full screen. And in source code you have fucntion like "DeSetWindowOFF()", but imho, will be nice to have just 2 functions:
DeSetWindow() and DeSetFullScreen(). It will avoid that visual jumping from win to full screen, and also will be (imho) more logical.

@freddix

Its really smooth. You can make it even better by making somekind of floor, maybe glassfloor or some other material that shows reflection of the ball.

EDIT: Also having some background but not a must.

@Kicko

As long as one can choose the original grey grid through some settings !

@Kas1e :
My command set is the same than DarkGDK from TheGameCreators
Concerning windowed/fullscreen mode, 3 options will be available ;)

1. Use of a default setup.ini file that'll contain some setup parameters like screen mode, depth & windowed/fullscreen mode. This function will be used if your program does not setup any video setting on beginning.

2. Use of DESetWindowOFF() or DESetWindowON() to switch from a mode to another one.

3. DESetWindowOFF() can be used before the DESetDisplayMode( int WIDTH, int HEIGHT, int DEPTH ) and then, when the display will be opened, it will be opened directly in the correct mode.

After this, window mode is set per default during dev car it's easier to have app window running with debug output window visible too at the same time ;)
Full Screen Mode will probably be set per default for final application developed under AmiDARK Engine.

@Kicko :
Yes, it's something planed like having a background picture or making a clone of WB screen so the ball will move above your icons :p (if someone know how to get the WB screen and clone it, tell me plz :p ) or having the capability to chosse a file for a background.

@Elwood :
lool. Texture is PNG image so you can change the image with everything you want ;) 3 differents but red/white textures will be available with the final screen blanker.

@All :
Thank you for your answer and comments :)

Kindest Regards,

Then no problems at all :) Cool. Hope to see new version of AmiDark soon (with music/sound of course :) )

Btw, did you have any amidark-related sources of games or demos which can be later ported on os4 ?

You can always ask the author of SGrab if he can help you with the grab of workbench window. Its really nice idea you got.

You can find his email in the readme for Sgrab

@Kicko
E-mail sent to the author of SGRAB ;)

Thanks.

@freddix
As others already mentioned, it looks really great on SAM. The animation is very smooth and fast. However on my screen there is some noticeable distorsion especially when the ball reaches the corners of the screen.

My display is a 4:3 17" TFT

I am really looking forward to make this the default blanker module on my SAM.

Keep up the great work.

struct Screen *wbscr=0;

wbscr=IIntuition->LockPubScreen("Workbench");
if (wbscr!=0)
{
// WB's bitmap (content) is wbscr->RastPort.BitMap
// ...

IIntuition->UnlockPubScreen("Workbench",0);
}

Reading a picture file you can use:
IIntuition->ObtainBitMapSource();
and
IIntuition->ObtainBitMapInstance();

Check the autodocs to find all the rest of the info you'll need.

Just try and dig into that :
