I know when you messaged me, i basicly said you can't do it. But let me suggest one way to make things a little simpler.
The IDEAL way would be to detect the building of creep colonies (and the destruction). Well although it is possable I gathered from my discussion with you that it requires changes to your map that your not willing to make.
Anyways I'm proboly too late to get you before you start making combinations. But you shouldn't make triggers for the combinations at all. What you should do is seperate the creep colonies and the sunken colonies and determan how many of each of them there are. Then add that to a total score and use that score to manage the amount of overlords you have.
So it would be something like this
| Trigger |
| Players: |
| ¤ Force 1 |
| Conditions: |
| ¤ Current player commands exactly 1 creep colony |
| Actions: |
¤ Set Custom Score for current player to 1
|
| ¤ Preserve Trigger |
You would then repeat this trigger many times for as many creep colonties you think a player might have.
Then make another group of triggers like this.
| Trigger |
| Players: |
| ¤ Force 1 |
| Conditions: |
| ¤ Current player commands exactly 1 Sunken Colony |
| Actions: |
¤ Add 1 custom score for current player.
|
| ¤ Preserve trigger |
So the first set would run, and determan how many creep colonies you have then the second set would determan the amount of sunkens and add that value to it.
Lastly you need an overloard balance system. There are a few ways you could do this. Like you could remove them one all while subtracting score simontainously and when there is 0 of one or the other then you know how many there are and witch value if ither is higher. The other method is more of a combination method but not as bad as what you were doing.
I'll demonstate that combination method
| Trigger |
| Players: |
| ¤ Force 1 |
| Conditions: |
¤ Current player Custom score is exactly 5
|
| ¤ Current player commands at at most 4 overlords. |
| Actions: |
¤ Create one overlord for current player at 'overlord storage'
|
| ¤ Preserve Trigger. |
and the reverse of that
| Trigger |
| Players: |
| ¤ Force 1 |
| Conditions: |
¤ Current player Custom score is exactly 5
|
| ¤ Current player commands at least 6overlords. |
| Actions: |
¤ Remove one overlord for current player at 'overlord storage'
|
| ¤ Preserve Trigger. |
You would then repeat those two triggers for every value of customscore (amount of creep + sunken colonies).
This set of triggers would equalize your overlords so there the same value as your custom counter.
Lastly you don't have to worry about setting the counter to 0 again or anything since the first set of trigger uses "set". So it won't continually increase, just make sure you have a trigger for 0 creep colonies as well.
I would lock this topic like requested but i think I kinda reopened it for conversation.
