Help with AddTile (tilemanager.lua)

[dinhkarate]

I really want to get tile_data.old_tatic_id and ground_tile_def.name in tilemanager.lua in original script game. But I don't know how to add to the original script so I tried to clone it in my mod, and think it gonna replace the original script.
I tried to put it a table and then call it in my prefab by the way
require 'tilemanager' --I think it like we call a library in lua.
but when I call the table I already define in tilemanager.lua it got nil. I have tried to make a function. 

Here is the code

turfss = {}   -- package

 

local function AddTile(tile_name, tile_range, tile_data, ground_tile_def, minimap_tile_def, turf_def)

    assert(mod_protect_TileManager == false, "Calling AddTile directly is not allowed")

    tile_name = string.upper(tile_name)

    tile_range = string.upper(tile_range)

    tile_data = tile_data or {}

 

    assert(TILE_RANGES[tile_range], "invalid tile_range: "..tile_range)

 

    local tile_id = GetTileID(tile_name, TILE_RANGES[tile_range], tile_data.old_static_id)

--Minh cần tile_data.old_tatic_id và ground_tile_def.name

    WORLD_TILES[tile_name] = tile_id

    INVERTED_WORLD_TILES[tile_id] = tile_name

    GROUND_NAMES[tile_id] = tile_data.ground_name or tile_name

    table.insert(turfss, {tile = tile_data.old_static_id, name = "turf_" .. string.lower(tile_name)})

 

    if ground_tile_def then

        ValidateGroundTileDef(ground_tile_def)

 

        ground_tile_def.old_static_id = tile_data.old_static_id

 

        table.insert(GroundTiles.ground, {tile_id, ground_tile_def})

--

        if ground_tile_def.flooring then

            GROUND_FLOORING[tile_id] = true

        end

        if ground_tile_def.hard then

            GROUND_HARD[tile_id] = true

        end

        if ground_tile_def.roadways then

            GROUND_ROADWAYS[tile_id] = true

        end

        if ground_tile_def.cannotbedug then

            TERRAFORM_IMMUNE[tile_id] = true

        end

 

        AddAssets(ground_tile_def, assets)

    end

 

    if minimap_tile_def then

        ValidateMinimapTileDef(minimap_tile_def)

 

        table.insert(GroundTiles.minimap, {tile_id, minimap_tile_def})

--GroundTiles.minimap la ten table, tile_id

        --minimap assets get added from minimap.lua

        AddAssets(minimap_tile_def, minimapassets)

    end

 

    if turf_def then

        ValidateTurfDef(turf_def)

 

        GroundTiles.turf[tile_id] = turf_def

    end

end

 

local function GettingTurf()

    return turfss

end
