Toost

Level viewer for Super Mario Maker 2, based on JiXiaomai's work. Hosted live at https://tgrcode.com/level_viewer/!

Usage

To load a local level file, press Load Level and choose a level. Wait a few seconds and the level will be rendered for you, along with some info. To load a level from a course ID, type your course ID into the textbox and press Download Level. As before, wait a few seconds and the level will be rendered. The rendered levels can be dragged with your mouse. You can also download them with Download Image, export info in JSON with Download JSON, or close the window to free up space with the x in the top left or with Close Level. To render levels without the grid, check Remove Grid and to render objects over pipes check Render Objects Over Pipes. You may also change the size of the image with Image Scale.

How to build

If building for desktop, obtain development files for sdl2, glew, glfw3, zlib, cairo, freetype2, and libcurl, as well as having an up to date GCC and pkg-config. Compilation on Windows should use MSYS2, on Mac should use homebrew and on linux should use standard GCC. Type make for a debug build and make BUILD=release for a release build. If building for web, first obtain a working Emscripten build environment and put its binaries on the path, such as emmake, emcc and em++. Next, run ./prepare_web_deps.sh. This only needs to be done once, as it downloads and compiles Cairo to prepare it for the web environment. Once that is done, you can run make PLATFORM=web for a debug build and make PLATFORM=web BUILD=release for a release build. To prepare a zip to distribute, run ./build_release.sh for desktop and ./build_release.sh web for web.

Hosting the web build

As long as all files in bin are in the same directory on your webserver and you are hosting them over https, you can access index.html to see the viewer.

Building in Docker

You can build and run the web interface in a docker container, making it portable, and negating the need to obtain dependencies and set up a development environment.

Get Docker
Build the docker image

docker build --tag toost .

Run the docker container

docker run -p 8080:8080 toost
