===== Craft recipe =====

//This node has no craft recipe.//

===== Extended description =====

  * When the rail is first built, this rail node does nothing. But once right-clicking (or double tapping on Android) the node, a formspec displays, allowing you to write Lua code for the current node.
  * Interacting with the ATC rail requires the ''[[usage:privileges:atlatc|atlatc]]'' privilege.
  * The code in the ATC rail is executed when an event is fired. See [[#events|Events]] for a list of events this node supports.
  * This node can be rotated by the [[usage:tools:trackworker|Trackworker]].
  * Only straight nodes are supported. You can't put this node on a curve or as a switch.
  * This node is an [[usage:nodes#component_types|active component]].

===== Operation =====

The LuaATC Rail is an active LuaATC component. It holds Lua code that is executed on specific [[usage:atlatc:events]], and interacts with the world using the [[usage:atlatc:api]].

Every LuaATC rail must belong to an [[usage:atlatc:environment|Environment]]. You can select the active environment using the dropdown on the top left.

//Note: you have to create an environment before LuaATC components can be used. See [[usage:atlatc:environment#Creating an Environment]].//

===== API =====

===== Trivia =====

The LuaAutomation ATC rail has the same texture as the [[usage:nodes:atc_controller|ATC controller rail]], but its functions are different. A patch has been posted on the [[:usage:mailing_list|Mailing List]], and is awaiting inclusion.
