Game crashes when animation image file is specified but missing

[burtlo]

The following Model had the misspelled image (it was suppose to be villain) and it failed to find the file and thus crashed.

class Villian < Metro::UI::Sprite

  property :pulsing, type: :animation, path: "villin.png",
    dimensions: Dimensions.of(64,64), time_per_image: 16

  def image
    pulsing.image
  end

end

I submitted a pull request to fix this issue.

It will cause the game to not crash, and send a nice message to the console informing the developer that the file was not found in the assets folder.

No such file or directory - assets/villin.png

It also adds in a stand-in file "missing.png" which is in the assets folder as a dummy image so the program continues to run, otherwise it will still crash. This file can be changed if you like to something that says "Missing asset" on the screen or something, but I'll leave that to you.

This update assumes that all image files will be held in the assets folder of a game development environment, which seems to be the case for metro set-ups.
