static Graphics bubolo.graphics.Graphics.getInstance ( )

staticpackage

Gets a reference to the Graphics system. The Graphics system must be explicitly constructed using the Graphics(width, height) constructor before this is called, or an IllegalStateException will be thrown. This method is package-private, because only objects within the Graphics system should have access to it.

Returns

a reference to the Graphics system.

Exceptions

IllegalStateException

when the Graphics system has not been explicitly constructed using the Graphics(width, height) constructor.

static Texture bubolo.graphics.Graphics.getTexture ( String  path )

staticpackage

Returns a texture from a path. Ensures that the same texture isn't store multiple times. Will load the file if it has not yet been loaded.

Parameters

path	the path to the texture file.

Returns

the requested texture.

Exceptions

FileNotFoundException

if the file is not found on the file system (can only occur if the file has not yet been loaded).
