Module extend_item

Extend callbacks of a registered node by wrapping them.

Allows injecting behavior before/after an existing callback while still optionally calling the original implementation via next.

The provided callback receives next as its first argument. Calling next(...) will invoke the original callback if it exists.

Functions

extend_item (node_name, extend_def, extend_def.)

Extend callbacks on a node definition.

Functions

extend_item (node_name, extend_def, extend_def.)

Extend callbacks on a node definition. Internally uses core.override_item to replace callbacks with wrappers.

Parameters:

• node_name string Name of the node in core.registered_nodes
• extend_def table Table of callbacks to extend
• extend_def. function Replacement callback that receives next as its first parameter followed by the original callback arguments.

Usage:

extend_item("default:stone", {
  on_punch = function(next, pos, node, puncher, pointed_thing)
    minetest.chat_send_all("Stone punched!")
    if next then
      return next(pos, node, puncher, pointed_thing)
    end
  end
})
