Limit Number of certain Buildings for Player

[Cyrax86]

Hi!

Do you know DARK DEEDS? There you can only have 1 Farm. If you have built one, its ''build button'' will become dark and the following text appears if the cursor goes over it:

Build new Farm
-Old Farm must be destroyed


How can I trigger this? And how can i limit a building to 2 or 3? (Even if their 'earlier versions' are upgraded?)

PS: The 'standard trigger' for limiting buildings makes the build button disappear. I dont like this...

Make a dummy unit called "Old Farm must be destroyed", and place it on the map for each unit.

Go to the farm, techtree, and add the requirement: "Old Farm must be destroyed", the dummy unit, that is.

Make a trigger that whenever a farm is constructed, every unit of type "Old Farm must be destroyed" owned by the player, is removed

Make another trigger that whenever a farm is destroyed, a dummy unit of type "Old Farm must be destroyed" is created for the owner of the farm

EDIT: ofcourse an alternative solution would be using the "Limit units of type "Farm" to 1 per player" action at map initialization, but that wouldn't add the "Old farm must be destroyed" requirement.

Eleandor loves dummy units =) it in most of his fixes (but it will do nicely)

Sounds good TY ;-)
But I have the following problem:

I limit e.g little houses to 2
Houses are upgraded in greater houses

Now have i build 2 little houses and upgrade 1 of them

The Problem:
Now I can build a small house again(!) though i have 2 houses on the map (normal one and upgraded one)

How can I prevent this?

 

[Eleandor]

It's just the way this is done

Hey,

I thought about your tip and I think I know now how I can use these 'Dummies' to solve my problems!

Thank you very much ;-)

hmmm..instead of limiting unit type try unit of type... there set the houses to be ancient or smt you dont used in other units. That will solve it. ---guess i am too late---

One action at map int does it all.
Limate training of Xtype to Xnumber.

It applies for both units and buildings.

I've suggested the same as solution 2. However, that would not show the "requirements" message, and if I recall correctly, it would simply remove the icon from the build menu, rather than making it "passive".
