I'm creating a VR experience for the Rift and I can't seem to get this script working properly. The script is meant assign footstep sounds to an AudioSource and play them once the player moves an assigned distance (stepLength). However, as it stands now, I can't count on the steps to play at all, and when they do, they lack any sort of rhythm that footsteps might. I've been fighting with this off and on for days, and I'd really appreciate some help!
Here's the whole FootstepControl script. All of the arrays are set to a length of 8 in the inspector and filled with .wav files.
#pragma strict
public var footstepSource : AudioSource;
public var watSteps : AudioClip[];
public var mudSteps : AudioClip[];
public var libSteps : AudioClip[];
public var intSteps : AudioClip[];
var currentClip : AudioClip;
var n : int;
var footstepSet : String;
public var fpc : CharacterController;
var distanceTravelled : float = 0;
var lastPosition : Vector3;
public var stepLength : float;
var counter : int;
function Start()
{
//cached data.
lastPosition = transform.position;
}
function Update()
{
counter++;
distanceTravelled += Vector3.Distance(transform.position, lastPosition);
print("frame " +counter + ": distanceTravelled1 " + distanceTravelled);
if(distanceTravelled > stepLength && fpc.velocity.sqrMagnitude > 0){
var p : int;
print("step " + footstepSource.clip);
footstepSource.PlayOneShot(footstepSource.clip, 1);
playSound();
changeSounds(footstepSet);
//So same sound doesn't play twice in a row;
p = Random.Range(0, 7);
if( n != p){
n = p;
}else {
n +=1;
}
distanceTravelled = 0;
}
lastPosition = transform.position;
}
//Change Sound as per location, set by trigger volumes.
function changeSounds(stepSet : String){
if (stepSet == "water") {
currentClip = watSteps[n];
}
if (stepSet == "library") {
currentClip = libSteps[n];
}
if (stepSet == "intRoom") {
currentClip = intSteps[n];
}
if (stepSet == "mud") {
currentClip = mudSteps[n];
}
}
function playSound (){
footstepSource.PlayOneShot(footstepSource.clip, 1);
}
Any insight would be really appreciated! Thanks!
