[Trigger] Need help with hero tavern

[twelveoclock]

Ok, I want a hero selection system in which you can manual select, random, all random, and repick a hero, with no duplicates of a hero. I looked at SD_Ryoko's hero tavern guide, but I don't think he takes out the hero out of the array if you manual pick, only random.(therefore, if you manual pick, there is still a chance of someone doing -random and get a hero already on the map)

Does anyone know how to fix his guide? (or is the guide working?)
I don't want there to be 2 of the same hero in play because many of the abilities aren't MUI.

I don't understand JASS at all.

If the Pick Mode is activated, simply deactivate the Random command ?

Anyway, I think there are a few maps like this in the spells section.

Whenever the "randomise" trigger runs, you pick every hero on the map and check if the randomly chosen hero is already picked. If this is true, randomise again until it's false.
