Compass

Compass

The compass script allows you to get 0-360 degree heading with respect to an arbitrary North reference object named "GPS Reference" of which the Z axis is pointed North. The compass uses a Sender to send the heading over a network.

Code

<javascript> var updateFreq = 1.0; private var heading = 0.0; private var gpsRef : Transform; private var gpsRefN : int; private var sender : Sender; private var timer = 0.0;

function Start(){ Init(); } function Update () { timer+=Time.deltaTime; heading = transform.rotation.eulerAngles.y - gpsRefN; if(heading<0)heading+=360; if(timer>(1/updateFreq)){ sender.Send(heading); timer=0; } // Debug.Log(transform.rotation.eulerAngles.y + " - " + gpsRefN + " = " + heading); }

function OnEnable(){ Init(); }

function Init(){ var gpsRefGO = GameObject.Find("GPS Reference"); if(gpsRefGO!=null){ gpsRef = gpsRefGO.transform; gpsRefN = gpsRef.rotation.eulerAngles.y; sender = gameObject.GetComponent("Sender"); } }

</javascript>
