    Alongside our brand new Learn platform, Unity’s Learn Content team have released a new beginner project. This project is a great way to introduce you to beginner code, physics, 3d environments, cameras and more, all wrapped up in a stealth game mechanic.

    Step by step, create your own haunted hotel game using the beautiful 3D assets provided. The written lessons have editor screenshots and gifs to help you learn how the adorably creepy hotel was created and make your own version for John Lemon to tremble around.

    For the first time we’ve released two versions of our project. You can find the tutorial project where you build the game from scratch, but also the completed project where you can see how we’ve made the demo level and play the game in the editor.

    Thanks for providing this!

    I found a small error in the tuitorial on this page:

    https://learn.unity.com/tutorial/setting-up-3d-beginner

    Under
    6. Layouts

    It says:

    4 Split
    This layout is good for looking at 3D models from different angles, but not much use for our 2D Project.

    This is a 3D project, so I found this bit confusing - but it's obviously copy-paste error.

    Not an error at all. If you read correctly, this part is just a description of all the available layouts in the editor whatever the project or tutorial you are working on.

    What's the usage license for the tutorial assets? I can't find it anywhere. Thanks!

    The licence details are probably inside the project resources you downloaded; generally a text file that displays in the Inspector view on launching the project.

    Thanks for answering, but I already looked there. :(
    There's no information about the license in the Asset Store project description either.
    I'll suppose they're free to use in any non-comercial project.

    For anyone interested this code snippet draws the pathing of the enemies (the waypoints) so that you can see what their patrol path looks like

    Code (CSharp):
    1. private void OnDrawGizmos()
    2.     {
    3.         Gizmos.color = Color.green;
    4.         for (int i = 0; i < waypoints.Length; i++)
    5.         {
    6.             Gizmos.DrawWireSphere(waypoints[i].position, .5f);
    7.  
    8.             if (i + 1 < waypoints.Length)
    9.             {
    10.                 Gizmos.DrawLine(waypoints[i].position, waypoints[i + 1].position);
    11.             }
    12.             else
    13.             {
    14.                 Gizmos.DrawLine(waypoints[i].position, waypoints[0].position);
    15.             }
    16.         }
    17.     }

    Just ran through this tutorial, all great stuff and a LOT of stuff for a beginner. Its a really well written tutorial, one bit of feedback I have is that it would be really helpful if you could include comments in your c# and shader code so that you don't have to always refer back to the tutorial pages to know what everything is there for (especially helpful in those shaders). Thanks for the great work!

    I'm new to Unity and am working on John Lemons Haunted Jaunt. I am getting the following error:

    MissingComponentException: There is no 'Animator' attached to the "JohnLemon" game object, but a script is trying to access it.

    I have gone through the script several times and in the Inspector Animator Controller I can see JohnLemon. I have googled this and cannot find a solution. Can you see where I am going wrong?

    Thanks,

    Dan

    Hello, I am currently in the Part 2 of the tutorial and I have followed the steps in order to make JohnLemon able to walk and turn, but in the end when i am playing the game the character only turns but he is unable to walk. I went back to my code to check for error but couldnt find any. I also copied pasted the code from the end of the tutorial, just in case i miss something but still no walking for the character. Any help would be welcome.

    Their is no reference and m_Animation
    I had 4 errors I did not give up I finished the script without errors just read what c# is telling you because I found auto type sometime gives u a way to do it different or correct it I was kinda excited to try it and I did JL falls through my code is correct ridge body physics?

    The thing is I get no errors - no warnings on Visual Studio.

    Also I see that
    using System.Collections;
    using System.Collections.Generic;

    are not getting used. Which is weird.

    you don't have to worry about it basically its saying that you're not using those in the script and you can remove them if you want to(Don't remove them until you have finished the tutorial)

    I know, but still my code doesn't work for walking and i have no errors - or warnings. Is it possible any of you that made it work, to post here the code for the PlayerMovement?

    here is the code, you can move him using wasd or arrow keys
    Code (CSharp):
    1. using System.Collections;
    2. using System.Collections.Generic;
    3. using UnityEngine;
    4.  
    5. public class PlayerMovement : MonoBehaviour
    6. {
    7.     public float turnSpeed = 20f;
    8.  
    9.     Vector3 m_Movement;
    10.     Quaternion m_Rotation = Quaternion.identity;
    11.     Animator m_Animator;
    12.     Rigidbody m_Rigidbody;
    13.  
    14.     // Start is called before the first frame update
    15.     void Start()
    16.     {
    17.         m_Animator = GetComponent<Animator>();
    18.         m_Rigidbody = GetComponent<Rigidbody>();
    19.     }
    20.  
    21.     // Update is called once per frame
    22.     void FixedUpdate()
    23.     {
    24.         float horizontal = Input.GetAxis("Horizontal");
    25.         float vertical = Input.GetAxis("Vertical");
    26.  
    27.         m_Movement.Set(horizontal, 0f, vertical);
    28.         m_Movement.Normalize();
    29.  
    30.         bool hasHorizontalInput = !Mathf.Approximately(horizontal, 0f);
    31.         bool hasVerticalInput = !Mathf.Approximately(vertical, 0f);
    32.  
    33.         bool isWalking = hasHorizontalInput || hasVerticalInput;
    34.         m_Animator.SetBool("IsWalking", isWalking);
    35.  
    36.         Vector3 desiredForward = Vector3.RotateTowards(transform.forward, m_Movement, turnSpeed * Time.deltaTime, 0f);
    37.         m_Rotation = Quaternion.LookRotation(desiredForward);
    38.     }
    39.  
    40.     private void OnAnimatorMove()
    41.     {
    42.         m_Rigidbody.MovePosition(m_Rigidbody.position + m_Movement * m_Animator.deltaPosition.magnitude);
    43.         m_Rigidbody.MoveRotation(m_Rotation);
    44.     }

    I initially couldn't get him to move as well, but once I checked the exact Case and Spelling in my script to the animator I created in Unity I could see my case was wrong.

    I found out what was it. In the animator my bool var was isWalking while in the code was IsWalking. fml! I was so frustrated

    I'm struggling with the chapter "The Environment". I cannot find the "MainScene" you're referring to. I'm using the "3D Beginner Tutorial Resources" package and there're no scenes inside of the project resources (as far as I can see). When I take a look into the "3D Beginner Complete Project" resource packages, I can find the MainScene of cause, but were I really wrong, using the Tutorial resource package instead of the "Complete Project" package?? Thanks Mario

    Ok, found my fault, I didn't saved sample scene in chapter 2 as main scene, therefore I was confused, because I thought there must be a preconfigured mainScene, instead it starts with the empty scene and dragging the level prefab into the scene is doing the trick.

    I started the tutorial quite exited and I got frustrated as soon as the code was introduced and ended up skiping and just pasting the code without reading most of the explanations. I just couldn´t follow.
    I think the coding part is way out of the scope of an actual beginner.I get it has to be takled but... maybe in a easier way.

    I am also having the same problem; my Visual Studio is also telling my there are no problems with my code but when i go into unity it gives me "Assets\Scripts\PlayerMovement.cs(17,35): error CS0246: The type or namespace name 'm_Animator' could not be found (are you missing a using directive or an assembly reference?)" and "Assets\Scripts\PlayerMovement.cs(18,36): error CS0246: The type or namespace name 'm_Rigidbody' could not be found (are you missing a using directive or an assembly reference?)"

    Hi, I'm having trouble on Player Character Part 2 - Step 17. When I hit Play, the character doesn't respond to input on other the directional arrows or w, a, s, d. Upon checking the "Animator" tab, I noticed that a light blue progress bar fills from left-to-right repeatedly while the scene is playing. Please see my movement script here to check for errors as well.

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;

    public class PlayerMovement : MonoBehaviour
    {
    public float turnSpeed = 20f;

    Animator m_Animator;
    Rigidbody m_Rigidbody;
    Vector3 m_Movement;
    Quaternion m_Rotation = Quaternion.identity;

    // Start is called before the first frame update
    void Start()
    {
    m_Animator = GetComponent<Animator>();
    m_Rigidbody = GetComponent<Rigidbody>();

    }

    // Update is called once per frame
    void FixedUpdate()
    {
    float horizontal = Input.GetAxis("Horizontal");
    float vertical = Input.GetAxis("Vertical");

    m_Movement.Set(horizontal, 0f, vertical);
    m_Movement.Normalize ();

    bool hasHorizontalInput = !Mathf.Approximately(horizontal, 0f);
    bool hasVerticalInput = !Mathf.Approximately(vertical, 0f);
    bool isWalking = hasHorizontalInput || hasVerticalInput;
    m_Animator.SetBool("IsWalking", isWalking);

    Vector3 desiredForward = Vector3.RotateTowards(transform.forward, m_Movement, turnSpeed * Time.deltaTime, 0f);
    m_Rotation = Quaternion.LookRotation (desiredForward);
    }


    void OnAnimatorMove()
    {
    m_Rigidbody.MovePosition(m_Rigidbody.position + m_Movement * m_Animator.deltaPosition.magnitude);
    m_Rigidbody.MoveRotation(m_Rotation);
    }
    }


    Any other suggestions for where I should check things are going wrong?

    I've finished the tutorial, and the game runs well in every way except for one: the long hallway with the two rooms and the ghost. I cant get Mr. Lemon to enter these rooms. For gameplay, entering these rooms is pretty vital, otherwise you die by ghost. How do I fix this?

    Sounds like you didn't name the Boolean variable IsWalking correctly during the Animator setup. Ensure it has a capital I and isn't spelled incorrectly as 'isWalking'

    Hi! I'm new to unity and have now almost completed the whole tutorial but I have a problem with my ghosts. I have entered the same position values as the tutorial show, however all ghosts (except the ghost in the first room, who is floating above the walls) go through the floor (see picture).

    I'm not sure what the problem is and what I need to change in order to make them walk on the floor. Is it something I have missed or something in the script?

    I encountered an issue when copying the PointOfView object into the Ghost (and making duplicates). Although the PointOfView object had the observer script and showed the Player and Game Ending as the expected objects, the collision did not happen. I had to reassign the same objects to the Player and Game Ending variables (even though they appeared to already be assigned). Is there some reference that may have been incorrectly copied? I believe I followed Dynamic Observers section 5 precisely.

    I couldn't get the ghosts to move along the nav mesh. Did anyone else have this problem by the time they reached the audio portion of the tutorial?

    have you checked to see if the y position value of your floor is beneath the y value for the ghost?

    Hi,
    I'm nearly at the end of "Player Character: Part 2" and I have to admit that there is not much that I can understand about the code that is being used so far.
    I'm not sure if it is presented just as an introduction of "how, where or when" to put code. Or, in order to continue further in the course, I am supposed to pecisely understand what Im doing... The thing is that I don't get it.
    Is this expected? Can I go on or should I leave it here?
    Thanks

    You are supposed to write the code yourself. And not rushing it, trying to understand each step then you wont run into these kind of bugs or you notice. What i am doing is i am trying to do the part by myself before reading. Then read it bt no look at code after i managed to do something working as intended i check the code to see how could it be writtten more effectively. Almost all the time i see i could write the code better yet almost every time i could do what i wanted to do somehow even if its not the best way.

    Actual beginner in this context is new to unity and game development. It doesnt have to mean no programming experience at all. Any source on anywhere will actually advice you learn some kind of programming before going through game development. As a beginner to unity and and game development,but having C programming background i found courses at exact level i suppose them to be. Unity learn isnt supposed to go through 30 hours of variables, loops course when there is hundreds of them can be found online for free.

    Pick a main stream programming language like python/c++ even javascript does the job. Find an online course. Go through it. Return when you finish, start over, try to understand each thing you do. It will keep you busy for 2 weeks 2 hours a day now. But it will save hundreds of hours later.

    I can't get past the second lesson because apparently, the asset does not import fully. As soon as it asks me to look at "root" I can only see legs but no arms, as the tutorial asks.

    I didntdo 3d one i am doing 2d one but did you try cleaning the project and downloading fresh ?
    Edit : Also double check constraints, rigid body and colliders. İts possible that you made a mistake and upperbody goes through floor due to gravity.

    Hi everyone. First let me start with a praise, great job with this tutorial, from the detailed (and encouraging :)) description, pace at which new concepts are introduced, script examples etc. This is how an introduction to a new framework / language should be done in general (and it rarely is).

    I would like to report a small issue I had with the WaypointPatrol script from the tutorial; all my ghosts stopped a bit before the first waypoint as the remaining distance was never smaller than the stopping distance. I don't know if I missed some configuration and the problem is on my side but such behavior kinda makes sense to me. With the expression changed to navMeshAgent.remainingDistance <= navMeshAgent.stoppingDistance the enemies behave as expected.

    Guys I seem to be having a problem even beginning the tutorial. Im trying to get the assests from the asset store. There are 2 results with the same thumbnail. Clicking the first one gives me a "Unfortunately, undefined is no longer available." and the second one gives me a 404 error then it says Im offline. This is all happening in the Asset Store within the unity engine. ANyone got a fix. I already tried to get the assets from the asset store on Google and it still doesnt work.

    Hey guys, so I'm almost done with this project and I'm really excited about that but something happened and I received this error message saying "
    Assets\Scripts\GameEnding.cs(23,19): error CS1061: 'Collider' does not contain a definition for 'GameObject' and no accessible extension method 'GameObject' accepting a first argument of type 'Collider' could be found (are you missing a using directive or an assembly reference?)
    " and I can no longer enter play mode, everything was working fine before and I have no idea what have I done to create this catastrophic mistake, none of my scripts seem to work anymore. Can someone help me out?

    Could you pls elaborate a bit, I too just finished tut, nicely done tho I knew a lot of it already but still some I did not, but after done with script in pace. and I made sure my script matched and its perfect ( that I can see) - JohnLemon just stands there arms straight out, does nothing, no rotation or movement ( I tried wasd and cursor keys),,what likely is wrong ? No errors of anykind anywhere.

    Using very latest unity through hub.
    Btw while not a long time programmer, I grasp in it entirety everything that is going on so its not that.

    thx

    HI,
    What do you mean none of your scripts seem to work anymore ?
    You may have inadvertently deleted something , a folder not sure, causing this.

    Do other scenes work , say load one you already had before this ?

    I Need Help.

    When I get caught by a gargoyle, it displays the "you made it" message instead.

    I have checked the references int the game-ending object and the POV object.

    I even checked if the images were the right way round.



    Does anyone have any advice?

    Hi,

    I am going through this tutorial, and new to Unity and programming.

    The "You Made It" screen displays permanently in play mode... can anyone point me in the right direction on how to fix this please?
