Long description

Long description
A random number generator that can actually be seeded. To interface with this RNG:

1) Get a handler:

Code: Select all

handler = remote.call("MT", "get_handler", seed)

seed is an optional parameter. If not supplied it will take the map seed.

2) Set the seed (optional):

Code: Select all

remote.call("MT", "randomseed", handler, seed)

handler is required. Without it, your program will crash. If you supply a wrong handler, you might interfere with other's rng or get an error.
If seed is not given, it will reset the seed to the map seed.

3) Get a random number:

Code: Select all

r = remote.call("MT", "random", handler, a, b)

handler: see above
Without a or b, it will return a random number(float) between 0 and 1.
With a but without b, it will return an integer between 1 and a.
With a and b, it will return an integer between a and b
