Mycraft

Mycraft is our Computer Graphics curriculum design based on modern OpengGL.

It's a clone of Minecraft mainly written in C++ and we have implemented both Mac version and iOS version for it.

Refer to Mobilecraft for more information about the iOS version.

Build

Install glfw & glew & assimp

Install glfw & glew & assimp with Homebrew.

brew install glfw
brew install glew
brew install assimp

Then add lib in Click Project Icon in Left Navigator - Build Phases - Link Binary With Libraries - Add libGLFW.X.X.dylib & libGLEW.X.X.X.dylib & libassimp.X.X.X.dylib then remove the not-found(red) lib in left navigator.

Then move header folder glad / KHR to /usr/local/include

Set XCode working directory

Set your working directory in XCode - Product - Scheme - Edit Scheme - Run - Working Directory to {Where Your Place}/Mycraft/Mycraft

Close shadow mapping if without independent graphics

For Macbook without discrete graphics, the game may lose its fluency greatly with the shadow on. You can comment out line 13 in /src/Render.cpp to ban it.

//#define SHADOW_MAPPING
