Every game programmer eventually has the urge to create their own game engine. This is mine. It's written in Scopes, an experimental programming language. Note you need a working install of Scopes in your path to use this framework.

Basic goals (for a first version):

• Good enough for sprite based games
• can be combined with game code in a standalone executable (+ supporting shared libraries)

Examples can be found in the demos folder. To run a demo, execute in the root bottle directory (for example):

scopes -e run.sc snake
# for demos in subdirectories, you use dots instead of slashes:
scopes -e run.sc gpu.buffers

Currently Linux and Windows (MSYS2 MinGW) are supported. If it seems like you have all dependencies and it still fails to install, please open an issue.

The exact package names for linux will depend on your distribution. You may need to install the following packages prior to running the bootstrap recipe:

• git
• cmake
• gcc
• make
• zip
• unzip
• rustc (might need to be installed manually if your distro ships a version that is too old)
• clang (used to build some rust libraries)
• python3
• libsdl2-dev (for the X11 dependencies)

Here are examples for a couple common distributions; you can then translate to your favorite package manager / distribution.

Arch Linux:

pacman -S wget git base-devel rust python3 zip unzip sdl2 cmake clang

Install all needed dependencies inside a MSYS2 shell:

pacman -S git mingw-w64-x86_64-python mingw-w64-x86_64-gcc zip unzip mingw-w64-x86_64-7zip mingw-w64-x86_64-make mingw-w64-x86_64-rust mingw-w64-x86_64-clang mingw-w64-x86_64-cmake

You should then clone bottle and bootstrap it:

cd bottle
wget https://hg.sr.ht/~duangle/majoreo/raw/eo?rev=tip -O ./eo
chmod +x eo
./eo init
./eo install -y bootstrap

After bootstrapping, you can then start a new project:

mkdir my_project
cd my_project
../bottle/install # initializes a new bottle project with all dependencies
scopes -e -c "import bottle; bottle.run;"

Happy coding!
