Class: Chingu::Text

Inherits:
GameObject show all
Defined in:
lib/chingu/text.rb

Overview

Text is a class to give the use of Gosu::Font more rubyish feel and fit it better into Chingu. Pure Gosu:

@font = Gosu::Font.new($window, "verdana", 30)
@font.draw("A Text", 200, 50, 55, 2.0)

Chingu

@text = Chingu::Text.new(:text => "A Text", :x => 200, :y => 50, :zorder => 55, :factor_x => 2.0)
@text.draw  # usually not needed as Text is a GameObject and therefore autodrawn
