# Dialogue
Formspec API to chat with NPCs
```lua
minetest.register_chatcommand("a", {
func = function(name, param)
local d = dialogue.new("Hi! I'm the blacksmith. How can I help you?")
d:add_option("What do you have for sale?", function(name)
print("ans: sale")
end)
d:add_option("Could you use any help?", function(name)
print("ans: ask for quests")
end)
d:add_option("Nevermind", function(name)
print("ans: nevermind")
end)
d:show(name)
end
})
```

* `d:add_option(answer_text, callback_func)` - adds option to dialogue builder
* `d:show(player_name)` - show to player name using dialogue.ask
* `callback_func` - called like callback_func(name_of_player_shown_to)
