Resource System

System for loading external files asynchronously.

• Resource folder (resources/)
  • Closed (resources/closed/)
    • Shouldn't change (Textures, Shaders, ...)
    • Packed path: ./res/
  • Open (resources/open/)
    • Meant to change (Configs, ...)
    • Packed path: ./

Building / Running

USAGE:
    evn [FLAGS]

FLAGS:
        --debug-callback    Enable Vulkan debug callback
        --dev               Enable Development mode
    -h, --help              Prints help information
    -c, --no-color          Don't color the console log
    -V, --version           Prints version information

• Development Mode

cargo run -p evn --release -- --dev

• Packed Mode

./pack_game.sh [-l | --linux] [-w | --windows]

This will

• Compile evn in release mode
• Strip the executable of symbols (size reduction)
• Generate a zip with the executable and open resources

Requirements

• Linux (maybe provide bat script for windows?)
• A windows cross compiler when compiling to windows

Shader compilation

Done with evn_shaderc, a command line wrapper around shaderc.

• Usage

./compile_shaders.sh

This will

• Compile evn_shaderc in release mode
• Run evn_shaderc with the correct arguments
  • Compiles GLSL shaders in evn/src/shaders/
  • Saves them in resources/closed/shaders/

Requirements

• Linux (maybe provide bat script for windows?)
