A seeded Random Data Generator.
Access via Phaser.Math.RND which is an instance of this class pre-defined
by Phaser. Or, create your own instance to use as you require.
The Math.RND generator is seeded by the Game Config property value seed.
If no such config property exists, a random number is used.
If you create your own instance of this class you should provide a seed for it. If no seed is given it will use a 'random' one based on Date.now.

state
<instance> state([state])
Description:
Gets or Sets the state of the generator. This allows you to retain the values that the generator is using between games, i.e. in a game save file.
To seed this generator with a previously saved state you can pass it as the
seed value in your game config, or call this method directly after Phaser has booted.
Call this method with no parameters to return the current state.
If providing a state it should match the same format that this method
returns, which is a string with a header !rnd followed by the c,
s0, s1 and s2 values respectively, each comma-delimited.
Parameters:
name | type | optional | description |
|---|---|---|---|
state | string | Yes | Generator state to be set. |
Returns: string - The current state of the generator.
