How to...
append an ItemStack's meta string onto an inventory tooltip?

edit: I should probably explain myself a bit better. I know how to do it, by using...

...in the formspec. What I would like to do is something like this example...
Given some node: "test:test". Now lets say I have an itemstack for said node and I set it's metadata to "fast". In an inventory it's tooltip will say "test", because that is it's name. I want it to say "test fast".
Do you think this is possible without having to edit existing inventory/chest mods?

Inventory slot tooltips are not configurable, and you can only change ones that you manually supply, like the ones on buttons, fields, etc.

That is bad news. Looks like I am going to have to figure something else out.

Try this: https://github.com/kaadmy/pixture/blob/ ... ec.lua#L80
You can't use it as an itemstack/inventory, so you can't take/put/move items in it, but you can use as an icon with an arbitrary tooltip.

well since my title is already here why make a new post and all that... lol .

i have a formspec with a box and a button the button is just supposed to see if the number in the box is 100 or not, if so set a variable to 0 if so set it to one, any Gurus have a good SIMPLE example?

Getting data from callbacks: http://rubenwardy.com/minetest_modding_ ... #callbacks

hate to be a pill but is there more or better examples?

or more to the point why is the player getting the call back? the abm has the form spec and needs the data...

or if you have form spec in an abm, and you have this code



can you still put the form name in there?
i sort of see why it says register_on_player_receive_fields its basically saying when the player performs action get fields right?

maybe i have the answer .. shall find out and return

Node callbacks don't call register on formspec submit, they call a callback in the node's definition. See the node part of that chapter, I think there is some info there.

But yeah, I'm planning on adding more examples.

nope but i messed it up a few times. i think im looking for something like this .. its from pipe works, im goinfg to study it and let ya know what i figure out.. sofar it makes no sense.

eight examples later im going the right way .... heres what i got



thats the form spec

this is how i handle the data...



have to put a little clapton in the debug, clapton and marley... lmao

from here i know how to get the data from meta:string_get and set

the only thing i cant figure out now is how to make the on recieve data reference a function in the same module.. i keep getting :

why if there is a number in the form spec and it works when i press the button do i get this error when i press escape to exit the form

[code]init.lua:434: attempt to concatenate field 'shaftdepth' (a nil value)[/code\]

got it to work .. will post results so that others who may have this problem can work through it ... in a minute

formspec to get the information.

handler to put data from formspec to nodes meta data... the trick to this is the if switch that rules out nil data. if you dont have that when you close the form the info goes to nil and you get erros, or in my case a block crushing crazy machine that tears up 10000 blocks as you blink.

That still might not work sometimes.

I'm not sure how tonumber acts when given a parameter that can't be converted to a number, so it should be set to 0 if it returns nil.
minetest.get_meta is the correct way, I think. minetest.env:get_meta should also work, somebody correct me if I'm wrong about this.

I can now, yay! I added a couple of lines to the engine source to allow me to do it.
