Legacy Code Support Functions

vl_legacy.deprecated(description, replacement)

Creates a wrapper that logs calls to deprecated function.

Arguments:

  • description: The text logged when the deprecated function is called.
  • replacement: The function that should be called instead. This is invoked passing along the parameters exactly as provided.

vl_legacy.register_item_conversion

Allows automatic conversion of items.

Arguments:

  • old: Itemstring to be converted
  • new: New item string

vl_legacy.convert_node(pos, node)

Converts legacy nodes to newer versions.

Arguments:

  • pos: Position of the node to attempt conversion
  • node: Node definition to convert. The node will be loaded from map data if nil.

The node definition for the old node must contain the field _vl_legacy_convert with a value that is either a function(pos, node) or string for this call to have any affect. If a function is provided, the function is called with pos and node as arguments. If a string is provided, a node name conversion will occur.

This mod provides an LBM and ABM that will automatically call this function for nodes with group:legacy set.
