Super Cool NetMythos Engine (Name Not Final)

This is a hobbyist game engine thing. I'm also using it for visualizations. Right now it is only meant to support WASM with WebGL but maybe at some point I will port it to build desktop apps.

Anyways, for the time being it's a hodgepodge.

If you want to use it, you'll need your main exe file to have a pub fn init() void {} and a pub fn update() void. You'll also need to import the engine and do something like comptime { _ = engine } to make sure the initial exports are compiled in correctly.

You'll also want to use a build.zig file that looks something like this:

const std = @import("std");

pub fn build(b: *std.Build) void {
    // The engine only supports wasm right now so if you set a whitelist here,
    // you won't have to remember to specify your target each time you compile.
    const wasm_target: std.Target.Query = .{
        .cpu_arch = .wasm32,
        .os_tag = .freestanding,
    };
    const target = b.standardTargetOptions(.{
        .whitelist = &.{wasm_target},
        .default_target = wasm_target,
    });
    const optimize = b.standardOptimizeOption(.{});

    // Import the dependency via your build.zig.zon
    const engine = b.dependency("engine", .{});

    const exe = b.addExecutable(.{
        // IMPORTANT! Right now the shell expects a file named game.wasm in the bin directory.
        // I will make it flexible eventually. But right now if you change this line,
        // Your project won't work right.
        .name = "game",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });
    // WASM doesn't use a normal entry point. The HTML/JS shell code is going
    // to handle calling our functions.
    exe.entry = .disabled;
    exe.root_module.addImport("engine", engine.module("engine"));

    // Here we install a pre-written HTML/JS shell. After building, if you
    // run a webserver with your zig-out dir as the root, you should see your
    // program.
    const shell_files = engine.namedWriteFiles("shell");
    const install_shell = b.addInstallDirectory(.{
        .source_dir = .{ .generated = &shell_files.generated_directory },
        .install_dir = .prefix,
        .install_subdir = "",
    });
    b.getInstallStep().dependOn(&install_shell.step);

    b.installArtifact(exe);
}
