_()!

http://irc.minetest.ru/minetest/2013-02-17#i_2877771

Core concepts

All functions are prefixed with :. All properties are prefixed with ..

Types

All stressed* members should have __type property containing theirs type as a string.

stressedPosition

Same as position. Can be created from either {x = …, y = …, z = …} or {…, …, …}

stressedNode

Created via _(position)

Implements:

• :value() — get node name
• :value("string") — set node name (like minetest.env:set_node())
• :meta("name") — get meta
• :meta("name", "value") — set meta
• :inventory("name") — stressedInventory (name is actually listname)

stressedNodeDef (what a weird name! better think of another one)

Created via _("name"), i.e. _("default:dirt")

• :on("event", function()) — registers event, possible ones:
  • dig
  • place
  • punch
  • rightclick

Global functions

• _:on("event", function())
  • generated
  • shutdown
  • …

Something

An example of code in stress:

_("default:dirt"):on("place", function(me)
    me:value("default:dirt_with_grass")
end)

same without stress

minetest.register_on_placenode(function(pos, newnode)
    if newnode.name == "default:dirt" then
        minetest.env:set_node(pos, {name="default:dirt_with_grass"})
    end
end)

Something more?

dirttograss = nil
_:on("chat", function(message)
    if message == "/dirttograss" and not dirttograss then
        dirttograss = _("default:dirt"):on("place", function(me)
            me:value("default:dirt_with_grass")
        end)
    elseif message == "/nodirttograss" and dirttograss then
        _(dirttograss):clear()
    end
end)
