# Overview

Paradise is a wasm first game engine written in zig.

# Status

Development stopped for now until zig stage2 async.

# Architecture

All images are embedded qoi images.

Keep engine as simple as possible.

# TODO

* Use package manager to fetch modules (priority)

* Find a way to fetch resources (not embed). We should wait for zig async/await in stage2.

* Find js object/function/string leaks.

* Port to other platforms (not now).

Add audio engine.

# Usage

```zig

const std = @import("std");

const platform = @import("platform.zig");

const paradise = @import("paradise.zig");

comptime {

    _ = platform;

}

pub const log = platform.log;

pub const gl = platform.gl;

var renderer: paradise.Renderer = undefined;

var sprite: paradise.Sprite = undefined;

fn update(_: f32) void {

    gl.viewport(0, 0, 800, 600);

    gl.clear(gl.COLOR_BUFFER_BIT);

    gl.clearColor(0.2, 0.3, 0.3, 1.0);

    renderer.start(800, 600);

    renderer.renderSprite(sprite);

    renderer.stop();

}

pub fn onKeyDown(key: u16) void {

    if (key == 37) {

        sprite.x -= 10;

        sprite.w = -@fabs(sprite.w);

    }

    if (key == 39) {

        sprite.x += 10;

        sprite.w = @fabs(sprite.w);

    }

}

pub fn main() !void {

    platform.init();

    platform.onKeyDown(onKeyDown);

    var image = try paradise.Image.load(std.heap.page_allocator, @embedFile("assets/character.qoi"));

    defer image.deinit(std.heap.page_allocator);

    sprite = try paradise.Sprite.fromImage(image);

    sprite.x = 100.0;

    sprite.y = 100.0;

    sprite.w = 64.0;

    sprite.h = 64.0;

    sprite.ox = 32.0;

    sprite.oy = 32.0;

    renderer = paradise.Renderer.init(std.heap.page_allocator);

    platform.run(update);

}

```
