FlatRedBallServices
Introduction
FlatRedBallServices is a static class which is responsible for initializing the FlatRedBall Engine, performing managed behavior, and drawing. Although managed behavior and drawing is technically handled by manager classes, the FlatRedBallServices exposes methods which initiate these behaviors. The FlatRedBallServices class also provides methods for loading and unloading assets from memory. It standardizes the process of loading assets both from file and through the content pipeline and provides simple methods to organize and unload content selectively. The FlatRedBallServices also provides access to common game elements such as the Game class itself, the Owner Control, and other classes.
Creating a FlatRedBall Application
The following 3 lines are required to add the FlatRedBall Engine to an XNA template:
For more information see the tutorial for Creating a FlatRedBall XNA Project.
FlatRedBallServices.Load
The generic Load method standardizes the loading of common FlatRedBall objects. The signature for the method is as follows:
The Load method can be used to load both FlatRedBall and XNA types. For more information on the Load method, see the Load page. For more information on the contentManagerName, see the FlatRedBall Content Manager wiki entry.
Random Numbers
To generate random numbers the FlatRedBallServices class exposes an instance of the System.Random class. The following code creates a random int between 1 and 6; similar to a 6-sided die.
The following code creates a random number between 0 and 10 inclusive:
The NextDouble returns a double value between 0 and 1. The code above multiplies it by 10 to get a value between 0 and 10. This value is a double, so the value must be converted to a float if it is to be used for a float variable.
Exiting FlatRedBall
To exit an application, call the Game's Exit method. This can be accessed through FlatRedBallServices:
