This function is not supported in earlier versions.

Sets the state ("seed") of the random number generator using the specified integer number.

Function

Sets the state of the random number generator using the specified integer number. Due to Lua's use of double-precision floating point numbers, integer values above 2^53 cannot be accurately represented.

Synopsis

RandomGenerator:setState( state )

Arguments

number state
The integer number with which you want to seed the randomization. Must be within the range of [1, 2^53].

Returns

Nothing.

Function

Combines two 32-bit integer numbers into a 64-bit integer value and sets the state of the random number generator using the value.

Synopsis

RandomGenerator:setState( low, high )

Arguments

number low
The lower 32 bits of the state value. Must be within the range of [0, 2^32 - 1].
number high
The higher 32 bits of the state value. Must be within the range of [0, 2^32 - 1].

Returns

Nothing.
