sow(seeds)

Reset the seed of the random data generator.

Note: the seed array is only processed up to the first undefined (or null) value, should such be present.

Parameters:

Name	Type	Description
`seeds`	Array.<any>	The array of seeds: the `toString()` of each value is used.

Source - math/RandomDataGenerator.js, line 83

state(state) → {string}

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	Argument	Description
`state`	string	<optional>	Generator state to be set.

Returns:

string -

The current state of the generator.

Source - math/RandomDataGenerator.js, line 322

timestamp(min, max) → {number}

Returns a random timestamp between min and max, or between the beginning of 2000 and the end of 2020 if min and max aren't specified.

Parameters:

Name	Type	Description
`min`	number	The minimum value in the range.
`max`	number	The maximum value in the range.

Returns:

number -

A random timestamp between min and max.

Source - math/RandomDataGenerator.js, line 296

uuid() → {string}

Returns a valid RFC4122 version4 ID hex string from https://gist.github.com/1308368

Returns:

string -

A valid RFC4122 version4 ID hex string

Source - math/RandomDataGenerator.js, line 239

weightedPick(ary) → {any}

Returns a random member of array, favoring the earlier entries.

Parameters:

Name	Type	Description
`ary`	Array	An Array to pick a random member of.

Returns:

any -

A random member of the array.
