    Is this related to a specific script? If not, reinstall unity.

    Nevermind :D It went away after I closed it out and restarted. I sometimes forget to do simple things like that.

    I am not to the stage in the book where opening the door considers whether or not I have first collected enough batteries becasue I am having a problem with what happens when I collide with the batteries. It is kind of wierd; before I try to test the scene, I see the empty battery in the HUD, but when I play the game and run into the batteries, I don't hear the sound and the batteries don't disappear. I get no errors when I save the code. Here is what I have for the PlayerCollisions.js:

    Apologies ahead of time if formatting left-justifies all my brackets (I always like to offset my paired braces).



    var batteryCollect : AudioClip;
    private var doorIsOpen : boolean = false;
    private var doorTimer : float = 0.0;
    private var currentDoor : GameObject;

    var doorOpenTime : float = 3.0;
    var doorOpenSound : AudioClip;
    var doorShutSound : AudioClip;


    function Update ()
    {

    var hit : RaycastHit;

    if(Physics.Raycast(transform.position, transform.forward, hit, 5))
    {
    if(hit.collider.gameObject.tag=="outpostDoor" doorIsOpen==false)
    {
    currentDoor = hit.collider.gameObject;
    Door(doorOpenSound, true, "dooropen", currentDoor);
    }
    }

    if(doorIsOpen)
    {
    doorTimer += Time.deltaTime;

    if(doorTimer > doorOpenTime)
    {

    Door(doorShutSound, false, "doorshut", currentDoor);
    doorTimer = 0.0;
    }
    }
    }


    /*

    function OnControllerColliderHit(hit : ControllerColliderHit)
    {
    if (hit.gameObject.tag == "outpostDoor" doorIsOpen == false)
    {
    currentDoor = hit.gameObject;
    Door(doorOpenSound, true, "dooropen", currentDoor);
    }
    }

    */


    function Door(aClip : AudioClip, openCheck : boolean, animName : String, thisDoor : GameObject)
    {
    audio.PlayOneShot(aClip);
    doorIsOpen = openCheck;

    thisDoor.transform.parent.animation.Play(animName);
    }



    function onTriggerEnter(collisionInfo : Collider)
    {
    if(collisionInfo.gameObject.tag == "battery")
    {
    BatteryCollect.charge++;
    audio.PlayOneShot(batteryCollect);
    Destroy(collisionInfo.gameObject);
    }
    }
    @script RequireComponent(AudioSource)





    Any help would be appreciated.

    I have been working through the book, and on Chapter 4 I created the Jscript as in the book, but I keep getting an error that reads:

    Assets/Scripts/PlayerCollisions.js(29,47): BCE0018: The name 'Boolean' does not denote a valid type ('not found'). Did you mean 'System.Boolean'?


    I am currently using the latest version of Unity (3.1 of3). Is there a change in the Boolean from 2.6 to 3.1?

    My post is right above yours. Without seeing the script, I am wondering if you put a capital "B" for boolean type when you wanted lowercase "b". Again, look at my code above your post and notice that I have a lowercase "b". I get no error on that.

    I am at the end of Chapter 5 and I am having a few issues. FIrstly the GUI text wont show up when I approach the door, and secondly when
    I collect the batteries it only takes 2 of them to fill the bar and picking up the others will only empty the bar, however; I can only open the door after collecting all 4. So the collecting of all 4 is still required but the textures are not displaying properly. thanks for any and all help. now i will post my code.

    PlayerCollison.js

    private var doorIsOpen : boolean = false;
    private var doorTimer : float = 0.0;
    private var currentDoor : GameObject;

    var doorOpenTime : float = 3.0;
    var doorOpenSound : AudioClip;
    var doorShutSound : AudioClip;
    var batteryCollect : AudioClip;

    function Update ()
    {
    var hit : RaycastHit;
    if(Physics.Raycast (transform.position, transform.forward, hit, 5))
    {
    if (hit.collider.gameObject.tag=="outpostDoor" doorIsOpen == false BatteryCollect.charge >= 4)
    {
    currentDoor = hit.collider.gameObject;
    Door(doorOpenSound, true, "dooropen", currentDoor);
    GameObject.Find("BatteryGUI").GetComponent(GUITexture).enabled=false;

    }
    else if (hit.collider.gameObject.tag=="outpostDoor" doorIsOpen == false BatteryCollect.charge < 4)
    {
    GameObject.Find("BatteryGUI").GetComponent(GUITexture).enabled=true;
    TextHints.message = "The door seems to need more power..";
    TextHints.textOn = true;
    }

    }

    if(doorIsOpen)
    {
    doorTimer += Time.deltaTime;

    if(doorTimer > doorOpenTime)
    {
    Door(doorShutSound, false, "doorshut", currentDoor);
    doorTimer = 0.0;
    }

    }

    }

    {
    audio.PlayOneShot (aClip);

    }
    /*function OnControllerColliderHit (hit : ControllerColliderHit)

    TextHints.js
    static var textOn : boolean = false;
    static var message : String;
    private var timer : float = 0.0;

    function Start()
    {

    }
    }

    function Update () {

    var hit : RaycastHit;

    Hallo!

    I am totally new in the game design area and maybe what I ask is silly, so a big sorry in advance! I am currently reading this book and I am in chapter 2 where I should design the outline of the island! I have made all the adjustments so far concerning the terrain script! BUT when I try to draw nothing is happening! I see nothing in the scene view, just the grey background. Any ideas?

    Thank you

    Maria

    Hi, I'm almost through with the book, and it has been very helpful. I will be using as a textbook in the Fall '11. But on page 201 of the 2009 print release in the OnTriggerEnter function I am getting an error.

    MissingFieldException: Field 'UnityEngine.GameObject.name' not found


    function OnTriggerEnter( collisionInfo : Collider ) {
    if ( collisionInfo.gameObject.tag == "battery" ) {
    BatteryCollect. charge++ ;
    audio.PlayOneShot( batteryCollect ) ;
    Destroy( collisionInfo.gameObject ) ;

    }

    if( collisionInfo.gameObject.name == "matchbox" ) {
    Destroy(collisionInfo.gameObject ) ;
    haveMatches = true ;
    audio.PlayOneShot(batteryCollect) ;
    var matchGUIobj = Instantiate( matchGUI, Vector3(0.15, 0.1, 0 ) , transform.rotation) ;
    matchGUIobj.name = matchGUI;

    }

    }


    I'm not sure what I'm doing wrong here,and in fact the code runs, and I can pick up the matches, but I hate having those Red Stop Sign Exclamations there. What am I doing wrong?

    Thanks again for this great book!

    Did you actually create the Terrain first? It doesn't sound like it... On p. 26 it says to go to "Terrain | Create Terrain" This will give you a blank slate on which to paint your terrain

    In chapters 2 and 3 it is talking about the FPSWalker script! I DO NOT have this script as a component of the First Person Controller! Instead I have a Character Motor script! Does it have the same kind of function with the FPSWalker script? Thank you

    Yes, I wondered about this as well, but yes, it appears to have the same functionality and then some. Did you sort out the Terrain issue?

    Yes I did :) thank God !! The problem finally was that the default layer was disabled and therefore no objects were rendered in the scene view.

    i need help in Ch 4 with making the door open and close. This is my code but i hate coding and am not very good at it so anyhelp would be great.


    private var doorIsOpen : boolean = false;
    private var doorTimer : float = 0.0;
    private var currentDoor : GameObject;

    var doorOpenTime : float = 3.0;
    var doorOpenSound : AudioClip;
    var doorShutSound : AudioClip;

    function Update () {
    if(doorIsOpen){
    doorTimer += Time.deltaTime;

    if(doorTimer > 3){
    Door(doorShutSound, false, "doorshut", currentDoor);
    doorTimer = 0.0;
    }
    }
    }

    function OnControllerColliderHit (hit : ControllerColliderHit){
    if (hit.gameObject.tag == "outpostdoor" doorIsOpen == false){
    currentDoor = hit.gameObject;
    Door(doorOpenSound, true, "dooropen", currentDoor);
    }
    }

    function Door(aClip : AudioClip, openCheck : boolean, animeName : String, thisDoor : GameObject){

    Hi! I have a question on Chapter 7, "Collecting the matches" section! I keep getting the following message ...

    http://hotfile.com/dl/127069288/3350a64/_.bmp.html

    I have written the code as exactly as it is written in the book but I am stuck! Any ideas?

    Kind regards

    Hi all,
    I'd like to add to the list of problems. This I assume is a real n00b problem so apologies if it is glaringly obvious. I imported the outpost for Chapter 4, created the script and loads fine. But when I reach the outpost and try to walk up the ramp my character walks right through it. Should there be another collider for the ramp? Am I using the right outpost? I'm using Unity 3.4.

    Thanks!
    Will

    Make sure that before you drag your model into your scene that you click on "Generate Colliders" within the FBX importer section. I'm betting that you missed that step, as I've done it a few times myself.

    That worked perfect! I had to re-add the outpost with the Generate Collidor checked. Thanks!

    Hello:

    I have made it to the end of Chapter 7 (yahoo!) but after slowly working out my other problems, I have one minor and one larger problem. The minor is that the crosshairs show up for a couple of seconds at the start of play and the fire won't light even if you have the matches (although the sound will go on.)
    I keep getting this error:
    NullReferenceException
    PlayerCollisions.OnControllerColliderHit (UnityEngine.ControllerColliderHit hit) (at Assets/Scripts/PlayerCollisions.js:62)
    UnityEngine.CharacterController:Move(Vector3)

    CharacterMotor:FixedUpdate() (at Assets/Standard Assets/Character Controllers/Sources/Scripts/CharacterMotor.js:331)


    And here's my full code for PlayerCollisions.js

    private var haveMatches : boolean = false;

    I just started with the book and am using Unity 3.4.2. Starting a new project the "Standard Assets.unityPackage" shown on page 25 no longer is listed in the list of packages. There is a "Standard Assets(Moblie).unityPackage" but scanning ahead in the book at the textures and assets expected the mobile version doesnt seem to be the same.

    Which packages should be selected when starting a new project to work through the book?

    I think pretty much every package besides Toon Shading (and probably mobile package) was in Standart Assets in the previous versions. If you're unsure which one to import, just import everything. Your project may take a bit longer to load but you won't get any errors that way.

    imo, you should at least import these:
    Character Controller
    Light Flares
    Particles
    Physic Materials
    Terrain Assets

    In chapter 6, the platform object I've loaded from the book's asset package has bad normals on a number of the surfaces. In particular planks of wood that make up the railing and one of the large pieces of the surface where you place the targets have the wrong normal up.

    Visually, that makes those pieces look like they are hollow with the top piece being transparent. If you move the camera to look underneath - you can see the texture on the underside which indicates that the poly/surface is indeed there but that the normal is inverted.

    Physically, that makes the coconuts (or player if you jump over there) behave badly. They pop through what should be the solid surface and can do some strange things after that.

    I've experimented with the settings in the FBXImporter for the platform but changing the Normals to "calculate" from "import" doesnt make any difference.

    Is this an issue others have seen? Is there a way within Unity to resolve it?

    Thanks!

    Yes, I have noticed this wonkiness. There isn't a way that I know of to fix this within Unity. I think it would have to be fixed in your 3D modeling software. I think.

    I think you are waiting for the new edition. I'm speaking of the older one. Hopefully the new edition will have fixed some of theses issues.

    Hello,

    yes I received it today and am on page 87 already. But I have a big problem:
    When trying to download the Book Assets package, I get a zip file, which extracts as another zip file. No way to get that imported. Unpacking it reveals many folders which I can't use. The learning stops for me at this point. Maybe somebody can help me?

    Thanks and regards
    Mario Gaida

    Amazing, it's been one week now, and still no change on packtpub's site.
    No way of getting the book assets unitypackage.

    Can somebody provide me the files by chance?

    Regards
    Mario Gaida

    EDIT: Everything's working! Just don't extract the files by double-clicking (MacOS), instead use StuffIt or another working unzip program.

    Does anyone hapen to have a copy of terrain just before you texture it in chapter 3?

    Been trying for ages now and just can't seem to make anything that seems useable.

    Its none. It is simply a practice tutorials to give you the basics. I read the book over a year ago and recently re-read chapter 2. I highly recommend this book. I have 3 Unity books and this is by far the best.

    I got the PDF version of the book and and while following the tutorials in the book, there is a misspelled animation clip name "doorcshut" in Chapter 5.

    I think that the book was written for Unity 3D 3.4 and not Unity 3D 3.5. I couldn't get the coconut shy to give me the power cell after knocking down three target and the particle systems are different in Unity 3D 3.4 and 3.5.

    Sorry to ask this again but does anyone have a copy of the terrain that they would be able to share.

    Been at it for days trying to make something that would be useable but nothing seems to work. I just don't think that making terrain is my kind of thing.

    Do mean a height map to import? I mean, they take only a few minutes to make. or do you want an entire terrain with base texture and completed splatting?

    Hey Roto.

    I was meaning the terrain as it is in chapter 3. I'd like to be able to texture it to atleast give that a go but if you are able to share it even after its been textured and everything that would be awesome. Not really sure what splatting is need to look at that :oops:

    I'm really looking to just get on with the scripting.

    I've completed the book, and you could literally use just a flat square for your terrain, it has no effect on the scripting or game play, it's purely aesthetics. If you really want it though I could prefab up my terrain for you.

    I am asking because I have made a game based on Survival Island. There are ten platforms-minigames scattered around a forest and the player has to complete all of them to win the game. It is ment to be for preschool children and it helps them to understand the numbers 1-5.

    Thanx

    Jeff - are you referring to Unity 3.x Game Development Essentials (2011) or the original 2009 book?

    This was indeed written for 3.4.2 but i'll be providing updates with regard to changes in 3.5 once we've finished and released 3.5!

    Keep an eye on unitybook.net for updates and errata.

    Also I've scoured Chapter 5 and I can't see a mistake - if you are referring to the new book, that is.

    Anyway thanks for buying the book I hope its helping you out!

    Hey Will,
    I read your 2009 book. Nice job. Of the 3 Unity books I bought and read, I found yours by far the most helpful.

    Oh ok. I never went any further in the book than the terrain part but now that you mention it it kind of makes sense :oops:

    If you don't mind packing up the prefab for it that would be awesome but if not thats cool. Thanks for letting me know either way though that I can continue on with out it.
