Node System

The Left 2 Mine mod uses a 'node system'. It can be tricky to understand at first but once learnt it's very easy to use.

There are two main block types in the 'node system': parent nodes and child nodes.

Parent Nodes

Parent nodes are usually connected to many child nodes. Parent nodes that are connected to a child node share the same colour.

When a parent node is first placed on the ground it will give itself a random colour. This colour can be used to determine which child nodes are connected to it. When a parent node is the same colour as a child node it is connected to it.

You can right click a parent node with your bare hands to link yourself to that parent node. While linked, any child nodes placed will be linked to the parent node. Placing a parent node will also automatically link yourself to that parent node.

Child Nodes

Child nodes must be connected to a parent node in order to do anything. If a child node is white text while placed on the ground it is not connected to a parent node. You can use a 'Node Linker' to link a parent node and child node. Child nodes are activated when parent nodes are activated.
