It is possible. If you look at the lobby code you can see the remenants of a similar function. All players would have to have the mod, and it would be a nonUI mod. It really isn't worth the effort, if people have the mod, then they would already be amiable to preventing double ups.

After some some brief looking around of the lua code (windows 7 search SUX), I found the functions that appear to handle assigning random heros in HeroUtil.lua, and it looks like they were trying to implement some sort of forcing of unique dg's, but then apparently gave up.. which doesn't really bode well..

Still, I think this mod would be pretty valuable to a lot of players so I'll continue looking into it.  I dunno what you mean by "It really isn't worth the effort, if people have the mod, then they would already be amiable to preventing double ups".  That's exactly why they would get the mod.  The types of games I'm talking about are where everyone in the lobby chooses random, and if everyone has the random dg fix, then everyone would be getting unique dg's.  No dual rooks, or all qot games..

but there would also be other requirements.

1. every team gets a general and with 4v4 and up two generals

2. the mod doesnt generate games with squishy teams against tank teams like, da, tb, qot against rook, beast, sedna

You could make it so that every team gets a tier 1, tier 2, and tier 3 with a conditional that prevents all assassin teams.

I have an idea:

Have it assign the demigods 1 at a time. For example, start with Team 1, Player 1. Then Team 2, Player 1. Etc.

If Team 1, Player 1 has a General, Team 2, Player 1 will get 1 as well. Also, Team 1, Player 2 will receive an Assassin, etc. Naturally, also checking each time that your team does not already contain this DG.

This would maintain an even mix of assassins and generals while still remaining fully (pseudo)random.

Also, I believe anything involving not allowing certain DGs to go up against others ( such as strong v weak ) is both subjective, and kills the random nature a good deal. Just my personal opinion there though.

Bollocks..

was searching through the forum for some answers to some other questions I had and found this thread.  Looks like mods are only executed ingame, thus modding anything else about the game (menu's etc).. more difficult than a simple mod atm.

That being said, I cant find documentation anywhere to confirm what Derog and morpheous said...

Have to do more reading up on whatever I can find I guess..

Well, where I left off I was at the point where I was pretty sure what needed to be changed to get unique randoms working, but I couldnt get anything outside of ingame changes to work.  I can make ultra boots of speed no prob, but simple test changes like changing default hero you start with when you join a game (instead of using the 'last used' dg) weren't working.

I was looking to try and add a function for adding and keeping track of random dg's in the for loop at line 1093 of  LobbyBase:HostLaunchGame in lobbybase.lua which I'm thinking would have made it a change that would only require the host to have the mod.  But I'm stuck trying to get simple changes to appear in the lobby menu.
