BiFpsGenerator
Frame generation engine, used for animation.
Each animation can have it's own BiFpsGenerator or it can use the global BiFpsGenerator. Different animations can share the global generator, which saves system resources. Use the factory method, instead of the constructor, to get the global generator. The frame generator generates FrameProgressionEvents a certain number of times per second, as specified by the framerate.
This class extends BiEventTarget and therefore all methods and fields available for BiEventTarget are also available for BiFpsGenerator .
Constructor
new BiFpsGenerator ( [ nFps ] )
Parameters
| Name | Type | Optional | Default | Descripton |
nFps | Number |  | BiFpsGenerator.DEFAULT_FRAME_RATE | Frame rate / Frames Per Second |
Properties
| Name | Type | get | set | Descripton |
currentFrame | Number | | Returns current frame. | |
frameRate | void | | | Sets the frame rate. |
Methods
| Name | Description |
dispose | Please call when you are finished using this object. |
isGlobalGenerator | Determines wether this is the globalGenerator or not. |
start | Starts generating events. |

Static Methods
| Name | Description |
create | Factory method that returns a global FPSGenerator, shared by all users, or a new unique generator. |
Static Fields
| Name | Type | Descripton |
