Making mercenaries available/unavailable

[Null]

I'm making a map where mercenaries are cards and I want that when I click on a mercenary the mercenary will completly dissapear from the building and after some time when some1 draws the card again the mercenary will become available again.

So there's an Action for Limiting the training of units, but it doesn't work for sold units.

A possible solution: Create localized Mercenary buildings for each player while hiding them from others. This way each player will have their own version of the Mercenary building stacked on top of one another, giving the illusion that they're all the same building. This Mercenary building won't actually Sell Units, and will instead Train them like a Barracks would. What you do is catch when the building begins training a unit (Event: A unit begins training a unit) and immediately cancel the training process. Then create the Trained unit-type for the owner of the Building at it's position. Finally, limit the training of this unit to 0 for EACH player. From there you simply Limit the training back to 1 for each player once the card is drawn again.

As alternative solution.
Add the Sell Units ability. Now you can use Neutral Building - Add Unit-Type (To Marketplace). Then you can use a second trigger that runs if a unit is bought and removes it from that.
However, if you want the charges (Sell amount) to stack you will need to use variables and manage that yourself (example: Card drawn more then once).

Erm... I've tryed Lartin's version, the trigger loooks like this and it doesn t work. What on earth am I doing wrong pls tell me
Yes the units appear

IIRC, triggering unit refers to selling unit, which refers to the marketplace (which 99% of the time would be neutral). Use owner of Sold Unit instead.

The trigger spawns the units so it recognises the triggering unit as the selling unit, the problem is that the only part which doesn t work is the remove unit from stock part
