FOSS gamedev and creative worlds

i am seeing if its possible to make a computer craft mod for Minetest (there is a lua interpreter written in lua so should not be too hard once i can get a GUI )

are there any introductions to making GUI's with the minetest modding api?

Minetest uses formspec for in game gui.

http://dev.minetest.net/formspec

Tutorial from the Minetest Modding Book.

However, the system is quite limited. Other people have tried to make computer craft mods, but been stopped by the limitations of formspecs.

this is the best i have so far


dose the minetest api have anything that could be used to display output?

also are there any good tutorials on how to receive and manipulate the input from input boxes in minetest?

as in this image i just used a input box for both

You could put your output in a new formspec.

ok so i am trying to get the input from the formspec stored in a variable
and i so far have this:

but when i run the command:

minetest.chat_send_all("Input: " .. fields.input)

nothing is shown in the chat not even the "Input:" part of the string

am i doing anything wrong?

Change your form name to mymod_form
You can not use a : in the name

Wrong. You can use a :

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

-- Show form when the /formspec command is used.

minetest.register_chatcommand("formspec", {
   func = function(name, param)
      minetest.show_formspec(name, "mymod:form",
            "size[5,6]" .. "textarea[1,0;2,3;input;Input;default]" ..
             "textarea[1,3;2,3;output;Output;default]" ..
            "button_exit[1,5.5;2,1;exit;Compute!]"

)
   end
})

minetest.register_on_player_receive_fields(function(player, formname, fields)
   if formname ~= "mymod:form" then return false end

   minetest.chat_send_all("Input: " .. fields.input)
   return true
end)

works for me.
Are you clicking the button? If you press enter it sometimes just closes it.

Sorry my mistake!

Are you clicking the button? If you press enter it sometimes just closes it.

i do get this output though when pressing the button though:

Are you using exactly the same code as posted? What Minetest version?
