[ThE-HaRBriNGER]

• Heavy Snow
  • Events
    • Player - Player 1 (Red) types a chat message containing -hsnow as An exact match
  • Conditions
  • Actions
    • Environment - Create at (Playable map area) the weather effect Northrend Snow (Heavy)
    • Environment - Set sky to Lordaeron Winter Sky
    • Environment - Turn (Last created weather effect) On

I want to know how i can make one certain title variable "Dalaran Grass Trim" turn into "Icecrown Ice" Does anyone know how to perform this trigger?

For instance how would i convert a terrain variable to a region variable.

Well I created this script to make things easier. It changes all tiles in playable map area of type x to type y.

Temp_Loc_1 should be a region at the lower left corner of your play area. Position exactly like this, so it's at the center of a tile. Setting a tile there helps to center it.

    • Time - Elapsed game time is 2.00 seconds
  • Conditions
  • Actions
    • Set Temp_Real_3 = 128.00
    • Set Temp_Real_1 = (((Abs((Min X of (Playable map area)))) - Temp_Real_3) + ((Abs((Max X of (Playable map area)))) - Temp_Real_3))
    • Set Temp_Real_2 = (((Abs((Min Y of (Playable map area)))) - Temp_Real_3) + ((Abs((Max Y of (Playable map area)))) - Temp_Real_3))
    • Set Temp_Integer_1 = ((Integer(Temp_Real_1)) / 128)
    • Set Temp_Integer_2 = ((Integer(Temp_Real_2)) / 128)
    • Set Temp_Loc_1 = (Center of Region 001 <gen>)
    • For each (Integer A) from -1 to (Temp_Integer_1 + 1), do (Actions)
      • Loop - Actions
        • For each (Integer B) from -1 to (Temp_Integer_2 + 1), do (Actions)
          • Loop - Actions
            • Set Temp_Loc_2 = (Temp_Loc_1 offset by ((Real(((Integer A) x 128))), (Real((128 x (Integer B))))))
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Terrain type at Temp_Loc_2) Equal to Lordaeron Summer - Dirt
              • Then - Actions
                • Environment - Change terrain type at Temp_Loc_2 to Icecrown Glacier - Ice using variation -1 in an area of size 1 and shape Square
              • Else - Actions
            • Custom script: call RemoveLocation(udg_Temp_Loc_2)
    • Custom script: call RemoveLocation(udg_Temp_Loc_1)

EDIT: This seems to bug with some map sizes. I'll try to fix it.
