how to limit buying a unit type to 1 ?

[kamyflex]

Good day ! my question is how to limit buying a unit type to 1 from a marketplace while other players must still be able to buy that unit, how can this be done ??

i tried disabling training of that unit type for the buying player but it does not work, any other solution is welcome

Thanks

The only thing I can imagine is to refund the gold and remove the unit if a player owns more than one.

You can create localized shops/hide buildings for players with triggers right?
So you could create the shop for each player and then add/remove the units sold by triggers.

There is a trigger action "Player - Limit training of (unit) to (integer) for (player)"
Make a loop that loops through all players and limit the training of your unit to 1.
I think that it also works on marketplaces but I am not sure.

Doesn't work on Mercenary camps, tested that.

Indeed, because Mercenaries are sold and not trained.

I guess that the neutral building - limit unit sold is for all players... could try that one too but I am not very confident about it.

If that doesn't work, then you should do something like this:
Event:
- Player 1 picks a unit.
- Player 2 picks a unit.
- Player 3 picks a unit.
- etc.

Conditions:
- Unit type equal to mercenary camp.

Actions:
- If triggering player has unit of unit type (unit)
- Then remove unit from mercenary camp.
- Else add unit to mercenary camp.

That should do it... Hopefully

That wouldn't be MPI if instances overlap. (..er wait what?)

To illustrate;

P1 has unit
P2 doesn't
P2 selects
P1 selects

that.

So you could create the shop for each player and then add/remove the units sold by triggers.

This in my opinion is the best solution.

But you cannot have more players buying from the same camp at the same time... or am I now totally forgetting everything in WC3?

did you try the solutions? I think they are quite good solutions but if they still didnt work maybe we can find a twist about it.

Thanks guys
for the moment i'm using 1 lumber to buy that unit, because there is no wood in my map, but the @chaosy solution is much more better, i'm gonna try it.

Exept that there is no "proper" way to get the money cost of a unit.

in my situation there is only one unit which is easy.
in case you have lot of unit i suggest creating that unit for a neutral player and cast transmute on it with a dummy caster, and see how much money you have which is the price of the unit in gold, and then reset the neutral player gold to 0.

 

[Wietlol]

I would make abilities based on "Some-neutral-spell-that-has-a-gold-cost" dont know the name atm but you can set its base id and a gold cost instead of mana.
With that you can disable the ability for a player.

Charge Gold?

 

[Wietlol]

Yea that is it

 

[Tickles]

Just give it a techtree requirement for a dummy unit which you can remove when that unit is purchased.

Interresting, when you find the name of the ability informe us pleas.

Does that furfills your request?

 

[kamyflex]

Event -
<Unit> (Marketplace) sells a unit

Condition -
Unit type of being sold = <My Unit Type>

Action -
Do multiple actions and conditions > if the player with the sold unit already has the same unit type, then delete the newly purchased unit and refund the player. If not, then continue doing nothing.
