Enemy on Map Counter

[LtDan]

Hey there everyone.
Im looking to make a counter that displays how many enemies are on the map at any given time.
How would i go about setting something like this up?

Make a Unit Group for each player. Then make a trigger with an event "A unit enters (Playable Map Are)" and then add the unit to the owning player's Unit Group. Then just count the amount of units in the group to show many units they have.

That will count dead units. Will have to remove them when they die. Sabe's solution is best if the map is very large and there would be lots of units at a time. If there are only a few then you can count dynamically by picking every unit in the map owned by each player and use these counts to periodically update a multiboard/leaderboard.

Or, if you have an unit indexer (which I recommend), you can just add unit upon indexing and remove it when it dies. With Bribe's unit indexer it could look like this

On Create

• Events
  • Game - UnitIndexEvent becomes Equal to 1.00
• Conditions
• Actions
  • Unit Group - Add UDexUnits[UDex] to PlayerUnits[(Player number of (Owner of UDexUnits[UDex]))]

On death

• Events
  • Unit - A unit Dies
• Conditions
• Actions
  • For each (Integer A) from 1 to (Number of players), do (Actions)
    • Loop - Actions
      • If (((Dying unit) is in PlayerUnits[(Integer A)]) Equal to True) then do (Unit Group - Remove (Dying unit) from PlayerUnits[(Integer A)]) else do (Do nothing)

You actually don't even need to have unit groups if you just want to count them. You can just have an integer array and +1 when a unit is created and -1 when a unit dies, but you might have other uses for storing them in a unit group.

There might be precreated natives for that:

constant native GetPlayerUnitCount      takes player whichPlayer, boolean includeIncomplete returns integer
constant native GetPlayerTypedUnitCount takes player whichPlayer, string unitName, boolean includeIncomplete, boolean includeUpgrades returns integer
constant native GetPlayerStructureCount takes player whichPlayer, boolean includeIncomplete returns integer

Edit: They also have GUI ports:

• Conditions
  • (Count non-structure units controlled by Player 1 (Red) (Exclude incomplete units)) Equal to 0
  • (Count structures controlled by Player 1 (Red) (Exclude incomplete structures)) Equal to 0

When you want to know the amount of one specific unitcode you can also ask for the current techlevel of that unitcode that would also include units counting as equals

constant native GetPlayerTechCount      takes player whichPlayer, integer techid, boolean specificonly returns integer

Doesn't this include for example dead or locust units though?

Locust units, yes.
Dead ones, no.
