Swap Node and Remove/Hide Formspec

[octacian]

I'm working on a (functional) computers mod. When the user enter the command "shutdown," the computer used my swap node functions (see here) to change to the off node. However, even though after the swap I use meta:set_string("formspec", nil) the formspec will still show when off after the player exits. I'd also like a way to hide the formspec automatically rather than the player having to press a button or <esc>.

I could use show_formspec on rightclick instead of the normal formspec meta, but I don't think that would be as efficient. I'm gonna have to do that anyway (I assume?) for other menus/inventories within the computer. However, I still am not sure it is possible to easily hide them.

One other issue that I mentioned in my previous post, is that swap node does not keep the facedir. If you can tell me how to keep the facedir with swap node, please do so on my other post to keep everything together (for other people's possible reference).

In general, doing show_formspec on rightclick ought to be fast enough, especially when it's a node that will display a specific menu anyway. The usually faster pre-defined formspec is mostly needed for things that come with an inventory and where quick access is highly desirable (like locked chests, though those seem to have become faster anyway).
Just provide swap_node with the facedir parameter. You need to read the node first in order to determine the value.

Krock showed me this trick:

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 node = minetest.get_node(pos)
node.name = "mod:another_node"
minetest.swap_node(pos, node)


Which preserves the facedir.

I could use show_formspec on rightclick instead of the normal formspec meta...

This is actually how the locked chest does it. The regular chest does not. If you want to have a formspec send a field that calls itself (dynamic menu, for example), then this is how you'd do it.

There are many mods that do this. You can look at my books mod for an example.

I already figured out swap_node, thanks anyway.

I probably will use show formspec when I get time to switch to it. Is there something like hide_formspec?

Thanks.

There's button_exit[]. Formspecs are escaped using the Escape key, or double-clicking outside the form.

Parsing the fields you'll see quit=true whenever it occurs.

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

minetest.register_on_player_receive_fields(function(player, formname, fields)
  print(formname)
  print(dump(fields)
end)
