say a user opens a formspec sets the data (custom integers and then closes it, how do you keep the user infromation stored or transfer it to another node, say the node destroys it self and moves itself. i know how to move the information just not how to update the form upon user exit or renetry/recreation.

"default is the default value of the field. default may contain variable references such as ${text} which will fill the value from the metadata value text."

If the value is related to the node, then you should store the value in meta like so:

Formspec is stored in meta:
Node Metadata
Node Metadata Formspecs

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: local createNodeFormspec(value) return "size[5,5]".. "label[1,1;This is shown on right click]".. "field[1,2;2,1;x;x;" .. value .. "]" end -- in the node definition: after_place_node = function(pos, placer) -- This function is run when the chest node is placed. -- The following code sets the formspec for chest. -- Meta is a way of storing data onto a node. local meta = minetest.get_meta(pos) if not meta then return end meta:set_string("value", default_value) meta:set_string("formspec", createNodeFormspec( meta:get_string("value") )) end, on_receive_fields = function(pos, formname, fields, player) if(fields.quit) then return end local meta = minetest.get_meta(pos) if not meta then return end meta:set_string("value", fields.x) meta:set_string("formspec", createNodeFormspec( meta:get_string("value") )) end

createNodeFormspec creates a formspec given some saved values - it's good to separate it like this to avoid duplication. default_value is some default value, you might for example use something like this:

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: meta:set_string("value", "")

which is the same as

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: local default_value= "" meta:set_string("value", default_value)
