Bagman remake : Amiga version available

[Nightshft]

Cool! First played bagitman like 4-5 years ago, but it's such a nice game. Hope you have good progress! =)

I found a way to reuse 95% of the code and keep most of SDL interface, but use the blitter behind the scenes.

I could blit basic images, but I still suck. Just for fun I started the game without trying to tune anything besides basic blitting. That's a mess but still...

Great job! Do you also plan convert c++ to c.

[jotd]

C++ to C no, sorry! there are a lot of classes and all. It's no longer useful since g++ does a good job as a 68k target.

Opens in a Window for me ???

The old amiga version is super-slow and uses SDL. It also opens a window. The new amiga version will be full screen

update on this:

- figured out a lot of blitter issues (still not all of them)
- could start the game main interrupt & refresh. Obviously still wrong blits, but palette is okay (at least in other tests), running 32 colors (original game uses 18 or 19 colors, strange but maybe I messed up when ripping the gfx)

Great work.
Is it possible to display it fullscreen now ??

@jotd

Cool, thanx for the new Amiga game.

[jotd]

yes it will be full screen.

well, the "game" isn't working like at all for now. Time to test the new Bebbo gdb server & source code level cross debugger

BTW does anyone has libpython27.dll ? because m68k-amigaos-gdb needs it and it's not in the gcc distro (it's python 2.7 DLL for cygwin).

Update: new gcc build has a working gdb.

[jotd]

thanks to the debugging sessions and a lot of step by step I was able to

- remove a fclose(f) that crashed my application. This may be a compiler/lib bug as the code has no issues reading from that file. I'll port the calls to Amiga native just to see
- thanks to the debugger I could fix some stupid fadein/fadeout buffer copy code that wasn't supposed to trigger. Instead, I should change the palette dynamically. We'll see later.

With this ironed out, the display is much cleaner. The position of the bags are too high (WTF it's okay in the other versions... we'll see), the text messages are turned off because they are sources of crashes but the rest is displaying fine.

Also I didn't implement the "cookie cut" blitter stuff yet.

Now let's figure out why nothing is updating, specially this dumb guard above. Debugger will be a precious ally here specially because in full screen it's difficult to print debug info...

[jotd]

making some progress despite the fact that I suspect gcc 6.5.0b to be VERY buggy. 6.4.x works properly, fortunately (but debugger not working...)

here 2 merged images (because I didn't implement a proper clear screen ATM) of menu + playfield. Fonts have some copy/blit issue (small gfx is using the CPU only) but starting to work

[pipper]

Try adding option -fbbb=- and see if this gets rid of some corruption. It disables Bebbo’s optimizations.

[jotd]

thanks, but it still crashes at random places when calling system routines (printf, fclose...)

Stack is set to 1MB just in case... but not helping.

To me Bagman-amiga-0.95 works well on AfA One, can you enlarge the window?

[AMIGASYSTEM]

The parameter -a has been used and the screen has been enlarged but it is rectangular

[jotd]

@AMIGASYSTEM yeah but SDL version on WinUAE is cheating. If you have a PC you can use the windows SDL version. I think there's a fullscreen option, but not sure on the amiga version.

I'm trying to create an amiga version that works on a A500/A1200.

As it should be

controls added. Game is playable. Lots of gfx glitches, missing clipping and all but reached the rightmost level and game mechanics work. Speed is correct too.



that will be my very first game on Amiga

BTW if someone wants to create music modules for that one (this is basically chiptunes, I've zoned the mp3s) I'd be interested.

[jotd]

update: playable very alpha version. Full of bugs/flickering but with sound (thanks phx!)

download in the zone. Needs a harddrive ATM but I can make it fit on a floppy with compression later. Needs 2MB ECS to run too. Speed is good.
Set the stack at 30000 (lower may work). this is a C++ program, not asm.
