Why does my footsteps in trigger script not work?

Questions & Answers

Hi! I’m trying to play footsteps sounds when we are in a trigger and we are walking. This script didn’t work… The comments explain further, thanks for helping in advance.

#pragma strict

//variables
var WalkingInTrigger : boolean = false;
var IsInTrigger : boolean = false;

//when enter trigger:
function OnTriggerEnter(other : Collider){
//when tag = player and press W
	if(other.tag == "Player" && Input.GetKey(KeyCode.W)){ //remember to tag player
//Change to true
	WalkingInTrigger = true;
	}

//And if the tag is player && is in Trigger (its in the OnTriggerEnter function)
	if(other.tag == "Player"){
//Change to true
	IsInTrigger = true;
	}
}

//When we exit the trigger:
function OnTriggerExit(other : Collider){
//And the tag = player
	if(other.tag == "Player"){
//Stop the audio
	audio.Stop();
	}
}


//function updates
function Update() {

//when WalkingInTrigger & IsInTrigger are true:
	if(WalkingInTrigger == true && IsInTrigger == true){
//Play audio
		audio.Play();
		}

//But, if only IsInTrigger is true:
	if(IsInTrigger == true && WalkingInTrigger == false){
//Dont play the audio. (So stop it)
		audio.Stop();
		}
}

i restructured you script so it uses less condition checks. I also moved the input check into update. Befor it onlc checked whether the player walked when he entered the trigger. Try this out:

#pragma strict
 
//variables
var WalkingInTrigger : boolean = false;
var IsInTrigger : boolean = false;
 
//when enter trigger:
function OnTriggerEnter(other : Collider) {
	//If the tag is player && is in Trigger (its in the OnTriggerEnter function)
	if(other.tag == "Player"){
		//Change to true
		IsInTrigger = true;
	}
}
 
//When we exit the trigger:
function OnTriggerExit(other : Collider) {
	//And the tag = player
	if(other.tag == "Player"){
		//Stop the audio
		IsInTrigger = false;
		WalkingInTrigger = false;
	}
}
 
 
//function updates
function Update() {
 
 	if(IsInTrigger)
 	{
	 	if(Input.GetKey(KeyCode.W)) {
	 		WalkingInTrigger = true;
	 	}
	 	
		//when WalkingInTrigger & IsInTrigger are true:
		if(WalkingInTrigger){
			//Play audio ifit doesnt play already
			if(audio.isPlaying) {
				audio.Play();
			}
		}
		else {
			//Dont play the audio. (So stop it)
			audio.Stop();
		}
	}
}

I dont know much about audio but I guess you can scrap the “IsWalking” variable entirely and only play the audio when they key is pressed.
