Web build different from editor (object missing, code not running as expected)

Having a bit of trouble with my web build, i’ve only been using Unity a short time so possibly i’m missing something obvious… I checked responses to similar questions and it hasn’t shed any light on this for me.

There are essentially two problems:

  1. My web build is missing a large plane which I use as a background. It was there in the previous build, now it is gone. Here is the old build:
    and here is the new one:
    As you can see, the background plane has gone. It’s still there in the editor.

  2. I have some code for the spikey enemies, which I have pasted below. It is suppose to have them shoot burst of 3 shots at different angles, and again, this works fine in the editor. Yet when I build it, they only fire the very first shot and none thereafter.
    (as before, this is the build in question: http://www.jonweinel.com/games/sub_test_build02/sub_test_build02.html)

Here’s the code:

	public float rotationSpeed = 10.0f;
	private float autoFireIntroSpeed = 1f;
	private float staggeredFireSpeed = 0.2f;
	private float startAngle = 90;
	private float angleStagger = 60;
	private bool firstOnScreen = true;
	private float autoFireSpeed = 2f;
	public GameObject enemyBullet;
	public AudioClip shotSound;
	private bool enemyShooting = false;
	public bool enemyActive = false;
	// Use this for initialization
	void Start () {

	// Update is called once per frame
	void Update () {
		// enemy is only active when visible.  note this can cause problems if enemy casts a shadow or goes behind something obscuring it from view.
		if (renderer.isVisible && enemyActive == false){
			enemyActive = true;
			enemyShooting = true;
		// if enemy is active, it rotates
		if (enemyActive == true){
			transform.Rotate(new Vector3(rotationSpeed * Time.deltaTime,rotationSpeed * Time.deltaTime, rotationSpeed * Time.deltaTime)); 
	void OnTriggerEnter(Collider col){
		if(col.gameObject.tag == "Player"){
		if(col.gameObject.tag == "bullet"){
			// you can only kill enemies you can see on screen
			if (renderer.isVisible){
				Debug.Log ("hitAnEnemy");
				GameObject thePlayer = GameObject.FindGameObjectWithTag("Player");
	IEnumerator EnemyGuns(){
		if(enemyShooting == true){
		//enemy gun shots
				// if the enemy has only just appeared on screen there is a short pause before it starts shooting
				if(firstOnScreen == true){
				yield return new WaitForSeconds(autoFireIntroSpeed);
				firstOnScreen = false;
				// then regular shooting is established
				GameObject newbullet;
				Quaternion shotAngle1 = Quaternion.Euler(0,0,(startAngle + angleStagger));
				newbullet = Instantiate(enemyBullet, new Vector3(transform.position.x, transform.position.y, transform.position.z), shotAngle1) as GameObject;
				//second shot
				yield return new WaitForSeconds(staggeredFireSpeed);
				GameObject newbullet2;
				Quaternion shotAngle2 = Quaternion.Euler(0,0,(startAngle + (2 * angleStagger)));
				newbullet2 = Instantiate(enemyBullet, new Vector3(transform.position.x, (transform.position.y), transform.position.z), shotAngle2) as GameObject;
				//third shot
				yield return new WaitForSeconds(staggeredFireSpeed);
				GameObject newbullet3;
				Quaternion shotAngle3 = Quaternion.Euler(0,0,(startAngle + (3 * angleStagger)));
				newbullet3 = Instantiate(enemyBullet, new Vector3(transform.position.x, (transform.position.y), transform.position.z), shotAngle3) as GameObject;
				// pause before next shots
				yield return new WaitForSeconds(autoFireSpeed);
				startAngle = (startAngle + (3 * angleStagger));

I finally found a solution to problem 2. (or at least, a cause, although i’m not sure why):

The audio call seemed to be what was stopping it from working properly. I have no idea why, but commenting out those audio lines seems to have solved the problem.

Not sure why the background plane disappeared, but i’m not using it anyway now…
