use on_recieve_fields with entity

[tbillion]

how can you process formspec data in an entity?

[tbillion]

minetest.register_on_player_receive_fields(function(player, formname, fields)

minetest.register_on_player_receive_fields(function(player, formname, fields)

Are you wanting a formspec to show when you click an entity?

[tbillion]

yeah, well actually when you punch an entity with a certain item (car key in this case) to show formspec ...

Well you can call minetest.show_formspec() from the entities on_punch callback, though you will probably need to include something in the formname to identify its origin.

Another way would be to store a reference to the entity in an (internal) table indexed by player name in on_punch, and use that in on_receive_fields to get back to it.

sorry for my lack of posting code i always forget to do 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


function car1.on_punch(self, puncher, time_from_last_punch, tool_capabilities, direction)
   local tool = puncher:get_wielded_item():get_name()
   local name = puncher:get_player_name()
   if tool == "mck:equipment_key" then
      local pos = self.object:getpos()
      local meta = minetest.env:get_meta(pos)
      local inv = meta:get_inventory()
      local invid = self.invid
      print(dump(self).." "..self.invid)
      --local meta = minetest.env:get_meta(pos)
      --local inv = meta:get_inventory()
      --local dumptruckdata = minetest.deserialize(meta:get_string("dumptruckdata"))

im actually already doing what you suggested stu.

Another way would be to store a reference to the entity in an (internal) table indexed by player name in on_punch, and use that in on_receive_fields to get back to it.

not sure what kind of reference i would use, now all the dump trucks have a unique id, i figured that out and i named the inventories with the unique ID, i just wasnt sure if there was an actuall call back for entities for on_receive_feilds, from what i have read there is not, which is a bit lame. but im working around it. now i just need a way to emulate on_destruct and remove the created inventories when the machine is destroyed.

you have to be kidding.. the data in the object is not persistant across server restarts ... jeeze if its not one thing its another. so how would you store data to an entity... there has to be a way .

### Entity definition (`register_entity`)

{
-- Deprecated: Everything in object properties is read directly from here

initial_properties = --[[<initial object properties>]],

on_activate = function(self, staticdata, dtime_s),
on_step = function(self, dtime),
on_punch = function(self, hitter),
on_rightclick = function(self, clicker),
get_staticdata = function(self),
-- ^ Called sometimes; the string returned is passed to on_activate when
-- the entity is re-activated from static state

-- Also you can define arbitrary member variables here
myvariable = whatever,
}

what do they mean by 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

        get_staticdata = function(self),
    --  ^ Called sometimes; the string returned is passed to on_activate when
    --    the entity is re-activated from static state

        -- Also you can define arbitrary member variables here
        myvariable = whatever,

@kaeza: i found what you were talking about in another post (viewtopic.php?f=9&t=4948), a lot of work to store one variable plus if the entity wont store its own id then any information in the table is pointless because you wouldn't be able to tell the trucks apart with out an ID because you never know where an entity will be,,,
