Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Sets the seed of the random number generator using the specified integer number. The default love.run calls this function at startup, so you generally don't need to call it yourself.

Function

Synopsis

love.math.setRandomSeed( seed )

Arguments

number seed
The integer number with which you want to seed the randomization. Must be within the range of [0, 2^53 - 1].

Returns

Nothing.

Notes

Due to Lua's use of double-precision floating point numbers, integer values above 2^53 cannot be accurately represented. Use the other variant of the function if you want to use a larger number.

Function

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

Synopsis

love.math.setRandomSeed( low, high )

Arguments

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

Returns

Nothing.

Examples

Set a random seed

 
love.math.setRandomSeed(love.timer.getTime())
