01.Jul.2023 New cross compiler/assembler: Calypsi
"Calypsi" is a collection of compilers and assemblers that run under Windows, Linux and macOS and can generate code for various retro platforms - among others, 6502 and 68000 processors are supported. Although the project is hosted on Github, the source code is not freely available and the use of the tools is only permitted for private purposes.

A runtime library for Amiga programmes is delivered with the compiler, it is described by the author as "work in progress". The associated source codes are available, cooperation of other developers is explicitly welcome here. (cg)

Preview video 31: Souverän Soccer
Daniel 'Daytona675x' Müßener (Wings Remastered, MiniGL4GL4ES, Tower 57) is working on a soccer game with 3D view called "Souverän Soccer" (amiga-news.de reported). He has written about his 31. preview video:

"Lots of stuff has happened during the past months, the highlights being:

about 30% wider goals!
optional radar!
no glued ball anymore, real dribbling!

Personally I always found SWOS or KickOff dribbling way too hard to master. Therefore my dribbling mechanics got some kind of twist, so that you get an unglued ball with the ease of use as if it was glued :) In a nutshell it works as follows:

Once you touch the ball, your player enters "dribbling mode". In that mode it will more or less auto-follow the ball, unless you make something like a 180 deg turn or stop moving. If you change joystick direction from e.g. up to up-right, then this direction change will not be applied immediately. Instead your player will continue to run up until he hits the ball for the next dribbling short-kick - and at this precise moment your current joystick direction will actually be applied and you continue dribbling up-right.

Expanding the goal's width was a rather tedious task because I had to heavily mess around with the carefully tweaked sprite setup to somehow make one more hw-sprite available for the larger goals. The new radar made this even more complicated.

Eventually one of the corner-sticks is now made using sprite #5 - whose DMA-channel isn't working: due to horizontal soft-scrolling and 32bit fetch-mode, only the sprites 0 to 4 remain fully functional here. And the fact that we're in 64 pixel sprite mode doesn't make it better. But with some hackery #5 was tamed - luckily the corner-stick is just a stick ;)

Anyway, til the next time!" (dr)
