[SCRIPT]Change to specific random map

[The chaser]

SetGlobalVarInt("maper", RandInt(1,3));
While (GetLocalVarInt("maper")==2)
{
SetGlobalVarInt("maper", RandInt(1,3));
}

That would still have a chance to choose two.

No, it wouldn't. This is how the script would go:

1. Randomly pick from 1 to 3

2(a). If you get something besides a 2, everything keeps going normally.
or
2(b). If you get a 2 you will enter the "while" script, because "maper" being equal to 2 fulfills the conditions under which the while will run.

3. The script inside the while will pick a new number for maper at random, also from 1 to 3. It will keep repeating this process until "maper" is no longer 2, because as long as it is, the while script will never end, and keep repeating itself.

You are a Genius.
