Tea

For simpler games from a simpler age.

Tea is a simple 2D game development library for Ruby. It’s designed with these things in mind:

0 is better than 1, and 1 is better than 2.
Simplicity beats speed.
Value and convenience can sometimes beat simplicity.
Procedural beats object-oriented in a dead-heat.

The aim of Tea is to bring back some of the grass roots game development that things like QBASIC fostered. By staying unobtrusive and out of the way, Tea lets you focus on your game or demo, and not the pointy bits that are part of many game engines and APIs.

Installing

First, get Ruby (www.ruby-lang.org) if you don’t have it already. Ruby 1.9 or later is recommended.

Tea is available as a gem on Gemcutter, so add gemcutter.org to your ~/.gemrc and type

gem install tea

Using Tea

First, require ‘tea’. This allows you to start using the rest of the Tea API.

From there, you have access to all of Tea’s modules, objects and methods. Below is a simple bouncing circle demo.

require 'tea'

Tea.init
Tea::Screen.set_mode 640, 480

x, y = 320, 240
dx, dy = rand() * 4 - 2, rand() * 4 - 2
r = 20

loop do
  if e = Tea::Event.get
    break if e.class == Tea::App::Exit
  end

  x += dx
  y += dy
  dx = -dx if x - r < 0 || x + r >= Tea::Screen.w
  dy = -dy if y - r < 0 || y + r >= Tea::Screen.h

  Tea::Screen.clear
  Tea::Screen.circle x, y, r, Tea::Color::MAGENTA
  Tea::Screen.update

  sleep 0.001
end

Status

All done.

Events/Input - done
Graphics - done
Sound - done
Fonts - done
