[Trigger] Unit group

[NightSkyAurora]

Hey everyone

Here is a trigger that spawns units of 3 different categories around the map.

trigger

• Spawn
  • Events
    • Time - Every 0.25 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in gNatural[1]) Less than 20
      • Then - Actions
        • Set Temp_Point = (pCenter offset by (Random real number between 600.00 and (Random real number between 4000.00 and 6000.00)) towards (Random real number between 0.00 and 360.00) degrees)
        • Unit - Create 1 uNatural[(Random integer number between 1 and 9)] for Neutral Passive at Temp_Point facing (Random real number between 0.00 and 360.00) degrees
        • Unit Group - Add (Last created unit) to gNatural[1]
        • Custom script: call RemoveLocation(udg_Temp_Point)
      • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in gNatural[2]) Less than 20
      • Then - Actions
        • Set Temp_Point = (pCenter offset by (Random real number between 600.00 and (Random real number between 4000.00 and 6000.00)) towards (Random real number between 0.00 and 360.00) degrees)
        • Unit - Create 1 uNatural[(Random integer number between 50 and 58)] for Neutral Passive at Temp_Point facing (Random real number between 0.00 and 360.00) degrees
        • Unit Group - Add (Last created unit) to gNatural[2]
        • Custom script: call RemoveLocation(udg_Temp_Point)
      • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in gNatural[3]) Less than 10
      • Then - Actions
        • Set Temp_Point = (pCenter offset by (Random real number between 600.00 and (Random real number between 4000.00 and 6000.00)) towards (Random real number between 0.00 and 360.00) degrees)
        • Unit - Create 1 uNatural[(Random integer number between 100 and 114)] for Neutral Passive at Temp_Point facing (Random real number between 0.00 and 360.00) degrees
        • Unit Group - Add (Last created unit) to gNatural[3]
        • Custom script: call RemoveLocation(udg_Temp_Point)
      • Else - Actions
    • Game - Display to (All players) the text: (String((Number of units in gNatural[2])))

I basicly repeated the same algorythem 3 times, but for the last 2 the units isn't added to the group. In other words, the unit keeps spawning but group[2] and [3] stays emty. Can someone explain why?

Thanks ^^

Groups do not exist unless it is created.
If you use group[array] it only initialisizes the first instance automatically in GUI, others dont exist.
You can increase the array size that is initialisized automatically in the variable editor by yourself. Just click on your variable and then increase the array size to 3.

Well that was easy... Thanks Iceman so are groups the only variable that don't initialisizes by itself?

 

[IcemanBo]

Everything. But for others you usually just can set them without need to create someting before.

But Timers and Dialogs also need to be created for example, just as groups.
