Here's a module to allow you to have a reproducible random number stream.
http://www.kweepa.org/step/ags/tech/SeededRandom.scm (2k)
Functions are:
RandomSetSeed(int seed)
RandomSetSeedString(String seedString)
int RandomInt()
float RandomFloat()
int RandomMax()
int RandomRange(int max)
See the header/code for more details.

Version History:
1.1 Updated to use x = (16809*x)%(2^31-1), so it has a period of ~2^31 instead of ~2^16
1.0 Initial version

Very useful for those who want to create procedural universe, but don't want to store everything in memory. The
seed is enough.
Think of the random dungeons in early RPGs (but it's still the same dungeon if you visit it twice).
I say yey for Steve.
I've recently read an article about Elite just before I've seen this module :)
Do you have any plans about a space opera?
Steve, you never cease to amaze me.
Roguelikes use seeded randoms a lot.
Why isn't anybody making a roguelike in AGS? Quick, somebody, make my dreams come true! =)
Haven't I told anyone about my roguelike sidescroller?
I really thought I had...

I tried :) Then gave up and started writing it in python. AGS isn't great if you want to use ascii.

In case you also feel like explaining how you did pathfinding, you know where to find my ears ;)
Oh, it's still got a long way to go before it's ready for that, but mostly it relies on strong AI in all parts of the code, handling things dynamically.
Updated the random number generator to have a period of about 2^31 instead of about 2^16, using the 'minimum standard' generator described in Park and Miller's 1988 paper:

This is a great generator because it works with signed ints as provided by AGS scripting. Most simple generators rely on unsigned ints or smaller word lengths.
So, err, hooray!
I used this module for a generated maze (https://www.adventuregamestudio.co.uk/site/games/game/2348/). Thanks!
