FlxHealthBar added to Flixel Power Tools

Health bars are a commonly used feature in games. From little health bars floating over players / enemies heads, to bars in the UI / HUD. This class provides a really fast way to create them, and they are highly customisable. It features:

• 3 different types of bar: Plain-colour filled, Gradient filled or Image filled
• All fill types support alpha levels
• Optional 1px border around the bar with configurable colour
• The bar can fill in one of 3 directions: From left to right, right to left or from the inside out
• Bars are associated with FlxSprites (its parent). When the health value of the parent changes, the bar updates automatically (within a given threshold limit)
• Bar can be fixed on-screen, and supports scrollFactor
• Bar can “float” with its parent at a given x/y offset from the parents origin

//  Create a tiny 32x4 health bar that floats above the "wolf" sprite
wolfHealth = new FlxHealthBar(wolf, 32, 4, 0, 100);
 
//  Tells it to track the x/y position of the wolf FlxSprite but offset by -5px on Y
wolfHealth.trackParent(0, -5);
