The following node groups are currently read by Advtrains: + +* `advtrains_signal`: When set, this property defines the type of signal this node belongs to. `1` indicates that this node is a static signal, and `2` indicates that this node is a signal with a variable aspect. +* `not_blocking_trains`: When set to 1, trains can move through this node. +* `save_in_at_nodedb`: When set to 1, this node should be saved in the internal node database used by Advtrains. + +# THE `advtrains` FIELD +The `advtrains` field in the node definition may contain the following fields: + +* `get_aspect(pos, node)`: This function should return the signal aspect of the node at the given position. + +* `set_aspect(pos, node, asp)`: This function should set the signal aspect of the node to `asp` if possible. `asp` is not guranteed to be an aspect supported by the node. + +* `supported_aspects`: This table should contain a list of supported signal aspects. |
