Count Farms

If I build a farm, I want a trigger to know that and save it to a variable, how do I do?

ANd the same if I destroy/sell/makeitdisappear, I need it to update the variable to know that I have gotten 1 less farm... How do I do that?

(No regions is allowed)

EDIT: 1 region can be allowed, but it need to work for 4 different players.

Could look something like this:

Untitled Trigger 003
Events
Unit - A unit Finishes construction
Conditions
(Unit-type of (Constructed structure)) Equal to Farm
Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Owner of (Constructed structure)) Equal to Player 1 (Red)
Then - Actions
Set farmsred = (farmsred + 1)
Else - Actions
Do nothing
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Owner of (Constructed structure)) Equal to Player 2 (Blue)
Then - Actions
Set farmsred = (farmsblue + 1)
Else - Actions
Do nothing

What u do with the integers after that is up to u :P

Someone correct me if I'm wrong here pls :)

This way is easier, and will take less time....
Make an integer array variable... Call it whatever you want, but I used farms in this case.

I'm doing this from memory, I don't have WC3 in front of me, so the wording won't be exact, but you should be able to find everything ok.


Events
Unit - A unit Finishes construction
Conditions
(Unit-type of (Constructed structure)) Equal to Farm
Actions
Set Farms=[Player number of (owner of constructed structure)] to [Player number of (owner of constructed structure)] +1

Events
Unit - A unit is killed (or whatever, just put muiltiple events. It only takes one to set them off)
Conditions
(Unit-type of (Dying Unit)) Equal to Farm
Actions
Set Farms=[Player number of (owner of dying unit)] to [Player number of (owner of dying unit)] -1

There you go. 1 is player 1, 2 is player 2, and so on. It's alot easier then the alternative....

Hope this helps.

You could use a variable or.....

use this condition or a variation of it

(Number of units in (Units owned by (Player(1)) of type Farm)) Greater than 0

would allow you to test if player 1 had any farms. It would be easy to make this do whatever it is including using it in a variable assignment.

Also to get it to work for all 4 players just use a For A : Loop

Good Luck.

Thanks everybody! I'll give you some credit for this in my map! :)
