As the error message states it tries to call a global function which you have declared as local.

Remove the local before the declaration of your function.

Make sure that create_gui definition is above the call of it in the file.
If event definition code is before it then function is not known to interpreter yet and gives an error.

But in this Code its working:

Code: Select all

script.on_event(defines.events.on_player_created, function(event)
	create_change_player_color_button_for_player(game.players[event.player_index])
end)

Code: Select all

local function create_change_player_color_button_for_player(player)
	local top = player.gui.top
	if not top[player_color_defines.names.gui.change_color_button] then
		top.add{type = "button", name = player_color_defines.names.gui.change_color_button, style = player_color_defines.names.gui_style.change_color_button, tooltip = {"gui.change-player-color"}}
	end
end
