Why do this?
Why not just use Godot/Unity/et cetera? Basque has a very different priority list than these engines. It is not a generic engine. There isn't much here, but it is a good starting point if you are looking to roll your own engine, here is what it does do:
- Map editing (with an easy to understand plain text format).
- Spritesheet animation.
- Background music.
- Collision detection.
- Some frame rate limiting (this should be improved).
At this point the engine will start becoming more specific to the game I am building, which is why I see this as the best time to open source it. Since it could be useful to others, either as a starting point, or just as a guide of how to do some things with SDL2. Note that all of the code is not necessarily the best solution to these problems, but it is a solution.
Basque currently requires:
- SDL2
- SDL2_image
- SDL2_mixer
- SDL2_ttf
Getting SDL2 installed:
Linux:
apt:
sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev dnf:
sudo dnf install SDL2-devel SDL2_image-devel SDL2_mixer-devel SDL2_ttf-devel Or whatever the equivalent package is for your distro.
Mac:
brew install sdl2 sdl2_image sdl2_mixer sdl2_ttf Windows:
Download the latest VC development files from: https://libsdl.org
Place the entire contents of
includeandlibunderC:\INCLUDE\SDL2.Copy all DLLs under
libtoC:\Windows\System32andC:\Windows\SysWOW64.Repeat for SDL2_image, SDL2_mixer, and SDL2_ttf.
Profit.
