DESCRIPTION:

Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it:

These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation.

SYNOPSIS:

class Ball < Graphics::Body
  def initialize w
    super

    # ...
  end

  def draw
    w.angle x, y, a, 10+3*m, :red
    w.circle x, y, 5, :white, :filled
  end

  def update
    fall
    move
    bounce
  end

  # ...
end

class BounceSimulation < Graphics::Simulation
  attr_accessor :bs

  def initialize
    super 640, 640, 16, "Bounce"

    self.bs = populate Ball
  end

  def update n
    bs.each(&:update)
  end

  def draw n
    clear
    bs.each(&:draw)
    fps n
  end

  # ...
end

BounceSimulation.new.run
