Build

1. Install CMake 3.14, C++ compiler, OpenGL.

Windows: VS2019 and workload Desktop development with C++

Ubuntu: apt install cmake g++ libgl1-mesa-dev libglu1-mesa-dev

MacOS: xcode-select --install and install CMake

2. Build AltCraft using CMake (run in directory with clonned AltCraft repo):

    mkdir build && cd build
    cmake .. -DCMAKE_BUILD_TYPE=Release
    cmake --build .

Windows: Just Clone a repository on statup screen in VS2019.

Linux and MacOS: Alternatively, you could build and run using IDE such as CLion.

Linux: There is a problem that Optick does not compile, so for now it needs to be disabled via the additional CMake parameter -DOPTICK_ENABLED=OFF.

3. Copy .minecraft/version/{version}/{version}.jar/assets/ to AltCraft-root/cwd/

You can extract .jar file as .zip archive.

/cwd/assets/minecraft/models/block/block.json must be a valid path.

4. Set /cwd/ as working directory and run AC: cd ../cwd/ && ../build/AltCraft
