Scrollscreen plugin for ImpactJS

This is a simple plugin that keeps the screen centered on the player, but doesn't scroll over the level boundaries.

Inspired by a post on the Impact forums by MyShuitings.

Usage

The plugin expects ig.game.player to contain the player entity (this is generally a good idea anyway).

EntityPlayer = ig.Entity.extend({

  init: function( x, y, settings ) {
    this.parent( x, y, settings );
    ig.game.player = this;
  }

});

Then just call scrollScreen() in the games update() function.

ig.module(
  'game.main'
)
.requires(
  'impact.game',
  'plugins.scrollscreen'
)
.defines(function(){
  MyGame = ig.Game.extend({

    update: function() {
      this.scrollScreen();
    }
    
  });
});
