Module: Chingu::Traits::Retrofy

Defined in:
lib/chingu/traits/retrofy.rb

Overview

A chingu trait providing easier handling of the “retrofy” effect (non-blurry zoom) Aims to help out when using scaling with “factor” to create a retrofeeling with big pixels. Provides screen_x and screen_y which takes the scaling into account Also provides new code for draw() which uses screen_x / screen_y instead of x / y

def draw
  @image.draw_rot(self.screen_x, self.screen_y, @zorder, @angle, @center_x, @center_y, @factor_x, @factor_y, @color, @mode)
end

#inside_window? ⇒ Boolean

Returns true if object is inside the game window, false if outside this special version takes @factor into consideration

Returns:

  • (Boolean)

def inside_window?
  self.x >= 0 && self.x <= $window.width/self.factor && self.y >= 0 && self.y <= $window.height/self.factor
end

#outside_window? ⇒ Boolean

Returns true object is outside the game window this special version takes @factor into consideration

Returns:
