Spring.AdjustHeightMap behaving oddly.

[yanom]

So I have this Lua code in a gadget:

Code: Select all

function gadget:UnitFinished(unitID, unitDefID, teamID)
	if(unitName(unitID)=="mnanoforge") then --test
		local unitx,unity,unitz = Spring.GetUnitPosition(unitID)
		unitx = math.floor((unitx+4)/8)*8
		unitz = math.floor((unitz+4)/8)*8
		
		Spring.SetHeightMapFunc(function()
			for z=0,Game.mapSizeZ, Game.squareSize do
				for x=0,Game.mapSizeX, Game.squareSize do
					currentAlt = Spring.GetGroundHeight(x,z)
					Spring.AdjustHeightMap( x, z, 200 )
				end
			end
		end)

        --Spring.LevelHeightMap(unitx-1000,unitz-1000,unitx+1000,unitz+1000,unity)
	end
end

This is supposed to raise up the whole map by 200m when a certain building is built. It sort of works:

All of the stuff on the map gets raised up, including the trees. If I build a tank, the tank can drive around on the "invisible ground" 200m up. But the map itself doesn't move up like it should! Bug?

seems to me like you are misusing Spring.AdjustHeightMap,
you should either call it just once outside of SetHeightMapFunc Spring.AdjustHeightMap(0, 0 Game.mapSizeX, Game.mapSizeZ, 200), or you should use AddHeightMap instead

Oh, it looks like AddHeightMap is actually what I'm looking for. That raises or lowers the map by a given amount, yesyes?
