DOJO FLOATS (10 liner)

DOJO FLOATS (10 liner) is a multiplayer game written in ugBASIC and that runs on ATARI 400/800 and TRS-80 COLOR COMPUTER 1/2.

The aim of the game is to sink as many of your own floats as possible, or to assign some of them to your opponent. It is played using DOJO, a protocol that allows for networked multiplayer games, which also works on FujiNet.

Click here to read the instructions on how to configure your emulator and / or your real computer to play to this game.  Important: if you have a FujiNet hardware, please use the Fujinet version (ATARI instructions here, COCO instructions here). Otherwise, we suggest to use the DOJO version, that can run on two emulators on the same modern computer (ATARI instructions here, COCO instructions here).

This game joins the  "BASIC10Liner" competition 2025.

Since it joined this competition, the game itself is modest in size, and the given source code respects strong constraints on the length of each line (category: PUR-120) and it does not rely on third party libraries. 

The source code is available on  this repository.

HOW MUCH HAS ugBASIC HELPED?

This cross-platform game would not have been possible without using ugBASIC: it is an isomorphic language and it has cross compilers that works on Linux and Windows, that directly converts high level algorithms into the assembly equivalent for the given CPU / computer.

Developing for multiple platforms requires very little effort because the source does not have to be adapted . With a single source code you can obtain programs for multiple retro computers, even very different from each other. Moreover, each target can have a dedicated optimizer, which allows to achieve very interesting results while leaving the BASIC code fully readable.
