I originally planned to make a 2D platformer with some more or less passable physics provided by a library that could be used outside of this project. Currently this project is just a sandbox for testing 2D physics and various 2D game related behaviors and functionality. It is also a project for learning the Rust programming language, which is turning out to be the harder piece of this undertaking.
Click one mouse button to spawn a small circle, click the other mouse button to spawn a bigger circle. You can play around with circles and forces.
Press P to spawn the player character (cat).
Press right and left arrow buttons on the keyboard to move the cat right or left.
Press spacebar to jump.
Press escape to quit the app.
Character controls are very rough at this point.
Use cargo build or cargo build --release or cargo build --profile release-lto.
Install these through your favourite package management tool, or via http://www.libsdl.org/
Ubuntu example:
sudo apt-get install libsdl2-dev
Fedora example:
sudo dnf install SDL2-devel
Arch example:
(Arch doesn't have separate regular and development packages, everything goes together.)
sudo pacman -S sdl2
You might also need a C compiler (gcc).
On macOS, it's a good idea to install these via [homebrew][homebrew].
brew install sdl2
In recent versions of Homebrew, the installed libraries are usually linked into $(brew --prefix)/lib.
If you are running an older version, the symlink for SDL might reside in /usr/local/lib.
To make linking libraries installed by Homebrew easier, do the following for your respective shell.
Add this line to your ~/.zshenv or ~/.bash_profile depending on whether you use ZSH or Bash.
export LIBRARY_PATH="$LIBRARY_PATH:$(brew --prefix)/lib"
You can also get sdl2 via macports.
sudo port install libsdl2
Then add the following to your ~/.bash_profile if not already present.
export LIBRARY_PATH="$LIBRARY_PATH:/opt/local/lib/"
If you're having issues with either Homebrew or MacPorts, [see here][pdev-issue].
