Need Help with Position of something

[TheSAguy]

Hi,

I'm trying to create a mod for a Solar mat. (Attached.)
They way it works is that I create a hidden solar panel with the placement of a tile.

My problem is that I group and delete hidden entities by identifying the position. Because I'm using a combination of Tile and Entities, I'm having a problem getting the same location.

Code

Building:

Code: Select all

local function Player_Tile_Built(event)

	local player = game.players[event.player_index]
	local robot = event.robot
	local surface = player and player.surface or robot.surface
	local position = event.positions

	for i, position in ipairs(position) do
		local currentTilename = surface.get_tile(position.x,position.y).name
		
		if currentTilename == "bi-solar-mat" then
			writeDebug("Solar Mat has been built")
			
			local force = event.force
			local solar_mat = surface.get_tile(position.x,position.y)
			local sm_pole_name = "bi_solar_pole"  
			local sm_panel_name = "bi_solar-panel_for_Solar-Mat"  
			  
			local create_sm_pole = surface.create_entity({name = sm_pole_name, position = position, force = force})
			local create_sm_panel = surface.create_entity({name = sm_panel_name, position = position, force = force})
			  
			create_sm_pole.minable = false
			create_sm_pole.destructible = false
			create_sm_panel.minable = false
			create_sm_panel.destructible = false
			
			
			group_entities(cantor(position.x,position.y), { solar_mat, create_sm_pole, create_sm_panel })	  			
			
		end
	end	
		
end

Removal:

Code: Select all

---------------------------------------------
local function Tile_Remove(event)
	

     local player = game.players[event.player_index]
     local tile_name = event.item_stack.name
     local tile = game.item_prototypes[tile_name].place_as_tile_result

     if tile and player.mining_state.mining and tile_name == "bi-solar-mat" then
          local tile_position = player.mining_state.position

          
		  --game.print("Tile "..tile_name..", pos "..serpent.line(tile_position))
		  

			writeDebug("Solar Mat Removed")
		--- Solar Map has been removed

			local pos_hash = cantor(tile_position.x, tile_position.y)
			local entity_group = getGroup_entities(pos_hash)
			if entity_group then
			writeDebug("Made it here")
				for ix, vx in ipairs(entity_group) do
					if vx == entity then
                    --vx.destroy()
					else
						vx.destroy()
					end
				end
			else
			writeDebug("Nope!")
			end
        ungroup_entities(pos_hash)
			

		  
     end

	
end

Currently I'm not deleting the hidden solar panel when mining the mat. and I believe the problem is that my position when placing the mat and when mining it is not matching up.
Could someone maybe review what I did and point out where I'm going wrong?

Thanks.
