GameTest

Demonstrator for simle game in Swift using SDL2. Should build on macOS and Linux.

Dependencies

You need to have SDL2 with some extensions installed in order to run this program.

macOS

On either Intel or Apple Silicone mac, use brew to install dependencies:

brew install sdl2 sdl2_image sdl2_ttf sdl2_mixer

linux

Use Apt on Ubuntu to install dependencies:

sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev libsdl2-mixer-dev

Compilation

After you have installed dependencies above, use SPM to build and run the game:

swift run

You're encouraged to experiment with build options like:

Build mode

Use -c to specify build mode, default is debug:

swift run -c release

Specify architecture

You may let the compiler know, that the program will run only on the same architecture as the architecture of your computer:

swift run -Xcc -march=native

At the time of writing not supported on Apple Silicone macs

Measure performance

An compiled into the program measures various loop events. Use macro to enable it

swift run -Xswiftc -DMEASURE

TODO

  • Improvements:
    • Add circles to AABB detection and resolution
    • Adjust speed
    • Adjust animation timings

Known issues

  • SDL2 Mixer will crash after calling Mix_CloseAudio when in debugging session

Notice: The aim of this repository is not full game, only proof of concept. Full game will be forked from this repo in the future.
