Emscripten with NimraylibNow!

This is experimental support for Emscripten. Please report any bugs.

1. Follow an amazing treeform's guide Nim Emscripten tutorial. As of 2021-05-08 only steps 0, 1 and 2 work, it is okay if 3 and 4 do not compile.
2. Compile the Nim source file (-d:release for extra speed):

$ nim c -d:release -o:public/index.html emscripten_crown.nim

3. Install and run nimhttpd server:

$ nimble install nimhttpd
$ nimhttpd

4. Open the output file in a browser http://localhost:1337/public/.

Tips and tricks

• Make sure to include config.nims in the same directory as your source file and edit it if needed.
• Replace while not windowShouldClose(): used for native compilation with emscriptenSetMainLoop and a callback as in the example.
• Music may not play if the window is not in focus, click on the game window to make it focused.

Compile options

NimraylibNowTotalMemory

Use NimraylibNowTotalMemory define to override the memory size, the default is 134217728:

-d:NimraylibNowTotalMemory=64000

nimraylib_now_web_resources and NimraylibNowWebResourcesPath

config.nims contains a nimraylib_now_web_resources define which includes files under "resources" directory into the virtual file system so that these files can be used inside your game, see packaging.

In order to disable it, remove --define:nimraylib_now_web_resources from your config file.

In order to change the path to "assets", add --define:NimraylibNowWebResourcesPath=assets to your config file.
