How to make a good Tips system?

You've probably seen them in many custom maps. A tips system. Every 20 seconds or so, a tip pops up with random How To play info.

How do I make such a Tips system? I don't know how to randomized things in Worldedit. Thanks in advance. :)

create a String array variable (lets call it STRING)
make a trigger to set the tips
set STRING[1] to Tip1:blah blah blah
set STRING[2] to Tip2:blah blah blah
set STRING[3] to Tip3:blah blah blah
.
.
how many you want...

make a second trigger to play the tips,
every 60 seconds of game time
chat message to all players STRING[random numer beetween 1 and 'how many tips you want'

done...

Well, from what I hear, random integer isn't all the random.

Another way is every 60 seconds display tipstring[A], where A starts at 1 and each time increases by 1, so it displays tip 1, 2, 3, and if it reaches a certain number [above how many tips u have], it resets A to 1.

Not random... but still tips.

Well, those are good tip systems, but not really random. You sure there isn't a way to randomly display these?
I've made a variable named TIPSTRING, gave it a String Array Size of 50 (for 50 different tips), and made the trigger to set the TIPSTRING[q] to this and that, TIPSTRING[2] To that and this.. etc..

You guys sure there's no way to randomly display these?



Edit: W00T! Never mind, I figured it out! Thanks folks!
