bad arguement #-1 to 'set_tiles' (number expected, got tabl

[Maniah]

I'm trying to create a "moat" around a certain area after the user clicked on a button.

Code: Select all

function plot_create_moat(event, plot_number)
	DebugPrint("Creating moat for plot " .. plot_number )
	local player = game.players[event.element.player_index]
	local surface = player.surface
    
	local waterTiles = {}
	local watertType = "water"
	local x = 0
	local y = 0
	local distance = 0
	
	distance = global.plot_table[plot_number]["inner_corners"]["top_right"][1] - global.plot_table[plot_number]["inner_corners"]["top_left"][1]
	DebugPrint("distance " .. distance)
	y = global.plot_table[plot_number]["inner_corners"][2]
	
    for i=0,distance,1 do
        table.insert(waterTiles, {name = watertType, position={x+i,y}})
    end
	
	DebugPrint(table_to_string(event))
	
	surface.set_tiles(waterTiles)
end

The last line of the function gives:

bad arguement #-1 to 'set_tiles' (number expected, got table)

I can use this code with the on_chunk_generated, but can't get it to work with the click.

Any ideas?

Code: Select all

y = global.plot_table[plot_number]["inner_corners"][2]

What is the value of this?

Yep, that was it, the value was invalid here.

Thank you!
