/**
|
|
* A Graphics object is a way to draw primitives to your game. Primitives include forms of geometry, such as Rectangles,
|
|
* Circles and Polygons. They also include lines, arcs and curves. When you initially create a Graphics object it will
|
|
* be empty. To 'draw' to it you first specify a lineStyle or fillStyle (or both), and then draw a shape. For example:
|
|
*
|
|
* ```
|
|
* graphics.beginFill(0xff0000);
|
|
* graphics.drawCircle(50, 50, 100);
|
|
* graphics.endFill();
|
|
* ```
|
|
*
|
|
* This will draw a circle shape to the Graphics object, with a diameter of 100, located at x: 50, y: 50.
|
|
*
|
|
* When a Graphics object is rendered it will render differently based on if the game is running under Canvas or
|
|
* WebGL. Under Canvas it will use the HTML Canvas context drawing operations to draw the path. Under WebGL the
|
|
* graphics data is decomposed into polygons. Both of these are expensive processes, especially with complex shapes.
|
|
*
|
|
* If your Graphics object doesn't change much (or at all) once you've drawn your shape to it, then you will help
|
|
* performance by calling `Graphics.generateTexture`. This will 'bake' the Graphics object into a Texture, and return it.
|
|
* You can then use this Texture for Sprites or other display objects. If your Graphics object updates frequently then
|
|
* you should avoid doing this, as it will constantly generate new textures, which will consume memory.
|
|
*
|
|
* As you can tell, Graphics objects are a bit of a trade-off. While they are extremely useful, you need to be careful
|
|
* in their complexity and quantity of them in your game.
