[Solved] Must I use random unit from unit group?

[KvickaN]

Is there a workaround of this so I don't have to pick a random unit? I rather want it to be any unit of a specific type owned by player 1 red within range, not a random one. Do I have to use a variable?

• ((Triggering unit) is in (Units within 100.00 of (Position of (Random unit from (Units owned by Player 1 (Red) matching (((Unit-type of (Matching unit)) Equal to Village) or ((Unit-type of (Matching unit)) Equal to City))))))) Equal to True

if you want a specific unit then a variable is the easiest solution, but maybe you should explain a little more what your trigger is supposed to to.

 

[IcemanBo]

Yup, you can use a unit[array] variable. The array variable should be defined to look like:

Unit[1] = Unit_For_Player_1
Unit[2] = Unit_For_Player_2
Unit[3] = Unit_For_Player_3
...

and when you use the "PlayerNumberOf(Player)" function instead of a fix number (1, 2, 3, ...) , then you can dynamically use it in triggers.

For example, we want to have a trigger that when a player presses "ESC" button, then we kill his unit:

• KillTrigger
  • Events
    • Player - Player 1 (Red) skips a cinematic sequence
    • Player - Player 2 (Blue) skips a cinematic sequence
    • Player - Player 3 (Teal) skips a cinematic sequence
    • Player - Player 4 (Purple) skips a cinematic sequence
  • Conditions
  • Actions
    • Unit - Kill Unit[(Player number of (Triggering player))]

.. PlayerNumberOf(Player) will automatically hold value "1" for Player1, "2" for Player2, and so on. Depending on which player triggered the event to run.

I don't think I quite get it, seems like I've tried everything, can't get it right!

See below, I've played around with setting variables but it doesn't matter what I do, I can never set:

• ((Triggering unit) is in (Units within 100.00 of PointTest[1])) Equal to True

To:

• ((Triggering unit) is in (Units within 100.00 of "UNIT TYPE OWNED BY PLAYER")) Equal to True

The goal is to check if there is a specific unit within range, if it is, it should complete the upgrade, if not the upgrade is cancelled (Haven't found a way to cancel an upgrade, just using method to replace the unit that is being upgraded)

Edit: Maybe if I create a region at triggering unit with the aprox size of the "within 100" and verify that there is a specific unit-type in that region? I'll test this.

Edit: Ok so I can't seem to get this to work either... You need (1) "village" in the region to be able to upgrade a "ground for spiritway" to a "spiritway". This is what I have at the moment:

    • Set BuildingType[5] = Ground for villages/citys (Unit-type) <- unit that upgrades to village

Edit: Hmm!! Maybe I can just make an aura on villages and check if spiritway is under the effects of that aura? Trying!

 

[IcemanBo]

It's more just a condition check, than a variable assignment. Maybe an example helps.

First variables need some value. Here we create a unit at map load for player 1, and assign the variable.

• Init
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Unit - Create 1 Footman for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
    • Set unit[1] = (Last created unit)

Now we can use the variable, and make distance check if needed like in your case. In the example the distance check runs, when Player 1 presses "ESC" button.

• Distance Check
  • Events
    • Player - Player 1 (Red) skips a cinematic sequence
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Distance between (Position of unit[(Player number of (Triggering player))]) and (Position of Scout Tower 0000 <gen>)) Less than 300.00
      • Then - Actions
        • Game - Display to (All players) the text: in range
      • Else - Actions
        • Game - Display to (All players) the text: not in range

^It checks if the unit of triggered player is in range "300" of an other pre-set unit.

 

[KvickaN]

Ahh, great man, thanks!

That worked like a charm!

 

[Vinz]

@IcemanBo I think he is referring to a (specific) unit-type, not a specific unit.

In which case the OP has to loop through 'Units Owned by Player of Type', and check the distance between them and the upgrading unit.

• Temp
  • Actions
    • Set TempUnits[0] = (Triggering unit)
    • Set TempPoints[0] = (Position of TempUnits[0])
    • Set TempInteger = 0
    • Set TempGroup = (Units owned by (Triggering player) of type Village)
    • Unit Group - Pick every unit in TempGroup and do (Actions)
      • Loop - Actions
        • Set TempPoints[1] = (Position of TempUnits[1])
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Distance between TempPoints[0] and TempPoints[1]) Greater than 100.00
          • Then - Actions
          • Else - Actions
            • Set TempInteger = (TempInteger + 1)
        • Custom script: call RemoveLocation(udg_TempPoints[1])
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • TempInteger Equal to 0
      • Then - Actions
        • -------- Cancel stuff --------
      • Else - Actions
    • Custom script: call DestroyGroup(udg_TempGroup)
    • Custom script: call RemoveLocation(udg_TempPoints[0])

 

[IcemanBo]

Can be, but I've seen also many times people use "Random Unit of Type < x > By Player" to refer to one specific unit from player, because they didn't know how to use unit variables, but they know the player has only 1 unit of this type.

 

[Dr Super Good]

If you want actions to apply to every unit in a group then use the pick every unit in group action and inside the loop block apply the actions to the picked unit.

If you want to apply actions to just 1 unit (do not care which) of a unit group then you can use the FirstOfGroup function on the unit group to get such a unit. Performance wise this is a lot more efficient than a random unit of a unit group due to more simple native logic.

native FirstOfGroup takes group whichGroup returns unit
