In game manager I keep getting an error towards the hud: "Error: In on_map_changed: [string "scripts/game_manager.lua"]:75: attempt to index upvalue 'hud' (a nil value)"
and the dialog box creates the error: Error: In on_started: "[string "scripts/dialog_box.lua"]:59: attempt to call field 'get_dialog_font' (a nil value)"
Clearly the problem is about the nil values but when I try defining either of them the error remains so I'm not quite understanding what to do....
Game_manager.lua -- Script that creates a game ready to be played.
-- Usage:
-- local game_manager = require("scripts/game_manager")
-- local game = game_manager:create("savegame_file_name")
-- game:start()
local game_manager = {}
-- Creates a game ready to be played.
function game_manager:create(file)
-- Create the game (but do not start it).
local exists = sol.game.exists(file)
local game = sol.game.load(file)
if not exists then
-- This is a new savegame file.
game:set_starting_location("house")

function game:on_unpaused()
-- Tell the HUD we are no longer paused.

-- nil means that the built-in effect.
function game:get_custom_command_effect(command)
return custom_command_effects[command]

local rupee_icon = sol.surface.create("hud/rupee_icon.png")
local rupee_text = sol.text_surface.create()
rupee_text:set_font("8_bit")
function game:on_draw(dst_surface)
rupee_icon:draw_region(0, 0, 12, 12, dst_surface, 10, 220)
rupee_text:set_text(game:get_money())

return game
end
return game_manager
And this is line 59 of the dialogbox script local font, font_size = sol.language.get_dialog_font()
