Inspired by:

In this project I learned how to:

• Install and build dependencies for a C project.
• Create a draw loop with raylib.
• Use the GuiSliderBar from raygui.
• Simulate gravity and friction.
• Draw text on the screen.

Dependencies:

• raylib.h: installed via pacman.
• raygui.h: built from source.

To build raygui from source:

git clone --depth 1 https://github.com/raysan5/raygui
mv raygui/src/raygui.h raygui/src/raygui.c
gcc -o build/raygui.so raygui/src/raygui.c -shared -fpic -DRAYGUI_IMPLEMENTATION -lraylib -lGL -lm -lpthread -ldl -lrt -lX11
sudo mv raygui/src/raygui.c /usr/include/raygui.h
rm -rf raygui

Building a shared object is not really needed, as #define RAYGUI_IMPLEMENTATION already does all the heavy work. So to get raygui.h without building:

git clone --depth 1 https://github.com/raysan5/raygui
sudo mv raygui/src/raygui.h /usr/include
rm -rf raygui

Compile with make all. Run with ./build/main.
