[Trigger] capping spawns

[scum_monkey]

hey i was wondering if anyone could describe to me the triggers that i would need to be able to place a cap on the number of units of a certain type on the map. the units are created through spawning only and i want to have a trigger that will bring the trigger to spawn more units back on after the population of the type of units being capped has come down again. if this has already been posted please post a link as i couldn't find anything resent on it

thanks

Maybe the integer function

• Unit Group - Count units in unit group

Using Units of type for the unit group may help you.

Use it for an integer comparison condition..

Just use a variable to store the number of those units in the map. Create a global integer, and each time you spawn a unit of that type, add 1 to the variable, and whenever a unit of that type dies, subtract 1 from it.
So, something like this...

• Spawning trigger
  • Events
    • Something - some event (periodic event maybe?)
    • Conditions
      • Integer Comparison - (NumOfUnits less then MaxUnits)
    • Actions
      • Unit - Create unit blah blah blah
      • Set - Set(NumOfUnits to Arithmetic(NumOfUnits + 1))

• Unit Dies
  • Events
    • A Unit Dies - Unit type equal to YourUnit
  • Conditions
  • Actions
    • Set - Set(NumOfUnits to Arithmetic(NumOfUnits - 1))

Make a different variable for each unit type, or try using arrays.
