Is it possible to swap terrain with triggers? For example:
When it rains, to switch grass terrain with dirt, so it could be "mud". But, to keep other textures (mramor, leaves....) the same.

Yes, it is:

  • Untitled Trigger 002
    • Events
    • Conditions
    • Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • (Terrain type at (Center of (Playable map area))) Equal to Lordaeron Summer - Grassy Dirt
        • Then - Actions
          • Environment - Change terrain type at (Center of (Playable map area)) to Lordaeron Summer - Dirt using variation -1 in an area of size 1 and shape Circle
        • Else - Actions
Loop through all tiles and check the terrain type, and change if needed.

When looping, create an intelligent method of points to check. One tile is 128x128, so each center of a square is 128 distance units away from the next one...

Save the original terrain type and variation into hashtable for example.

Could I just put grass in variable and just change it in that trigger?
Could you be mode specific please about this 128x128 thing ^^

And, that trigger didn't work for me =(

Here's a test map I slapped together in a hurry. It's not a polished system, but it works.

Hit ESC to change grass to grassy dirt and grassy dirt to dirt. Hit ESC again to load original tiles.

I improved my system. It bothered me because it was not good enough.

  • You can set the region you want to apply changes to
  • Uses coordinates, not locations
  • Uses one unit, instead of separate unit for each point
