Component: Navigation

This is the component provided by the Navigation Upgrade.

Component name: navigation.
Callbacks:

• getPosition(): number, number, number or nil, string
  Gets the current relative position of the robot. This is the position relative to the center of the map item that was used to craft the upgrade. Note that the upgrade can be re-crafted with another map to change it's point of reference. Returns nil and the string out of range if the robot is too far away from the point of reference (i.e. when it is out of bounds of the map that was used to craft the upgrade).
• getFacing(): number
  Gets the current facing of the robot, as one of the sides constants.
• getRange(): number
  Gets the effective range of the upgrade. If the absolute value of the relative X or Z coordinate becomes larger than this, getPosition() will fail.
• findWaypoints(range: number): table Note: Requires version 1.5.9 of OpenComputers.

  Finds all waypoint blocks within the specified range.
  This returns a table that contains other tables. The top table has only numbered indices corresponding to each detected beacon. In each of this entries is another table, each row various aspects of the specified beacon: “position”, “redstone”, “label”.

  • position returns a table with numbered indices in which 1 is x, 2 is y, and 3 is z. These numbers are the distance from the navigation component to the beacon in terms of block coordinates.
  • redstone returns a single number that is the current strength of the redstone signal
  • label returns a string that is the label of the beacon you can set by right clicking on it.
    
    Below is an example of how the tables are set up. A single beacon's results are shown.

    table: main 
    table: 1	table: position	1:	number: x distance
    		2:	number: y distance
    		3:	number: z distance
    	redstone		number: redstone strength
    	label		string: beacon label
