For anybody getting the object not set to an instance ... And that is using TextMeshPro in the newer Unity Versions Here is what you should do Add this to the top of the selectionmanager: using TMPro; Then u also have to change these 2 lines: Text interaction_text; --------------> TextMeshProUGUI interaction_text; interaction_text = interaction_Info_UI.GetComponent(); ---------------> interaction_text = interaction_Info_UI.GetComponent(); I hope this helps :)

If your like me and don't want the selectionmanager to select stuff across the map, you can simple change this if (Physics.Raycast(ray, out hit)) to if (Physics.Raycast(ray, out hit, 10))

First off, amazing tutorials and explanations! The best I have came across, great at explaining the little details. I laughed so hard when you were creating the rabbits and you went over one and said "oh I stepped on one" as if the rabbit felt it. Keep doing what you are doing, we really appreciate it!!!

Alright, first of all, I'm loving this tutorial series. I'm planning to follow them through until I have something cool playable. Second, reading some comments about problems other had, and making a little research, I found a way to use TextMeshPro instead of the legacy text. your code should be something like this: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using TMPro; public class SelectionManager : MonoBehaviour { public GameObject InteractionInfo; TextMeshProUGUI interaction_text; private void Start() { interaction_text = InteractionInfo.GetComponent(); } void Update() { Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; if (Physics.Raycast(ray, out hit)) { var selectionTransform = hit.transform; InteractableObject interactable = selectionTransform.GetComponent(); if (interactable) { InteractionInfo.SetActive(true); interaction_text.text = interactable.GetItemName(); } else { InteractionInfo.SetActive(false); } } } } The gist of it is using TextMeshProUGUI as a variable type, instead of just TextMeshPro. Don't forget to use "using TMPro" at the top of the code too. Hope this helps someone.

For anybody have a problem with the rabbit face down when idle state, you should freeze the x and y rotation in rigidbody

for anyone who has problems with the item name not showing when you look at an object, Make sure that the object has a collision box. I've been pulling my hair out for hours with this problem, yet the solution was kind of obvious haha. Could just be a problem for me because I'm using different assets. anyways, love your videos and how you explain everything. Thanks man

If you cant find the animator tab, its under window in the ribbon alog the top window/animation/animator if you are getting The type or namespace name 'InteractableObject' could not be found. its because you need to create a seperate c# script named 'InteractableObject' and then place the code in description for it in it.

Hey Mike, Thanks for the tutorial. Just a small suggestion: it's always very helpful to provide the assets you use in your tutorial to the viewer. For example, even something simple as importing that white sphere you use for the reticle took me like two hours since I needed to download image software and figure out how to create the right type of image.

Im really enjoying going over these videos, Ive never really working in 3d, and these explanations are really good. Ive had various problems when adding stuff to the game world, and had a lot of fun tracking down the issues, and figuring out where I went wrong.

An addition to your raycast would be a float for ray distance, otherwise you will hit everything in the game world. So = if(Physics.Raycast(ray, out hit, 2f)).

best tutorials i ever seen about unity thank you so much

One of the best tutorials out there !

I subscribed because of how good this tutorial is :)

21:07 you might already know this but if you hold right mouse button you can use wasd to move

how come when im trying to sort out the selection manager the interaction info ui doesnt show up please help

If you are having trouble with the selection script you first also have to have the interactable object scripts

READ IF YOU CANNOT GET YOUR TEXT TO SHOW WHEN YOU HOVER OVER AN INTERACTABLE OBJECT: (this worked for me) -Ensure that the interactable object has a collider on it. If its an asset that you made yourself or different to the one Mike is using, input a mesh collider - when you click play, make sure you actually click into the game (ur PC Cursor should disappear when you click into the game). Your camera will be able to move while ur not actually clicked into the game, but the UI won't work untill your cursor disappears by clicking into the game. This should fix the problem.

Mike thank you for your tutorials! It's motivate me to explore all details and even try to do some modifications.

Error whiile in playmode: "object reference not set" on SelectionManager script copy and paste this, Note: In the unity editor you will need to drag the players camera into the "Camera" reference using System.Collections; using System.Collections.Generic; using TMPro; using UnityEngine; using UnityEngine.UI; public class SelectionManager : MonoBehaviour { public Camera playerCamera; public GameObject InteractionInfo; TextMeshProUGUI interaction_text; private void Start() { interaction_text = InteractionInfo.GetComponent(); } void Update() { Ray ray = playerCamera.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0)); RaycastHit hit; if (Physics.Raycast(ray, out hit)) { var selectionTransform = hit.transform; InteractableObject interactable = selectionTransform.GetComponent(); if (interactable) { InteractionInfo.SetActive(true); interaction_text.text = interactable.GetItemName(); } else { InteractionInfo.SetActive(false); } } } } Hope this helps

Hey guys, I'm sorry for those who are looking for answers to their errors, so if you're getting the error about the interactable object in the selection manager script all you need to the is make sure you have the interactable script imported with the stuff mike has. hope this helped some of u

So here's an interesting question. Here's the setup: The trees that I'm using to do this tutorial are from a pack I've already purchased. I did everything correctly to set up the text per Mike's instructions. But it just wasnt doing anything. So after double checking it, I added some debug messages to the SelectionManager Script.. I had it tell me after the hit what transform it was finding, and after the if statement where it was looking for InteractableObject, whether or not if found it. It was making a hit, but the transform it returned was the LOD0, not the parent. So, it was not finding the Interactable Object. It took me a second to recognize that it wasnt testing the parent of the Tree... because the hit was being made on it's LOD0... and so when I put InteractableObject on it's LOD it worked fine... It didnt matter whether or not the tree was rendering LOD4, as long as the code was attached to LOD0 it worked fine... Does this sound like it's working as designed to you all? Do you think I should report it to Unity as a bug? Anyway for anyone using a different tree... Hopefully this comment will help, and hopefully it will save you the proverbial banging of the head against the wall i did.

I have this really weird issue, everything is working fine but when the rabbits are idle on a sloped surface they just face plant into the ground and try to hop into the ground, when the idle timer is up and they start start to run again it goes back to normal until they idle on a slope again. does anyone have the same problem or does anyone know how to fix it

i love you,this is best tutorials i've seen

Hi, I like the way you explain, glad I found you. I will definitely follow this series. It would also be good if, during the explanation, you would add how the script would be done if, for example, instead of the first person, you used the third person, what would the difference be.. As for the rest, it's a really good tutorial... Best regards, and keep up the good work ...subscribed

Also: Change the Box Collider to enable Trigger. Next Add Navmesh agent component to each the rabbit prefab and set Base Offset to like -0.10. Disable the original AI_Movement Script or replace it with AI_Movement_Navmesh script. Add a NavMeshSurface (if you don't have one already) component to your Terrain and Bake. (I use Unity 2022.3.25f1)

If text doesn't appear when you hover over the object with cursor, try adding collider to your prefab. That's how it worked in my project.

For the most part it is working, the only problem is that the interactable text doesn't disappear when I look away from the object everytime. Not sure if this is a collision issue, I am using the mesh collider for my objects. It is almost as if it randomly decides when the text should disappear. I am using legacy text not text mesh pro.

If you’re having trouble with the text not showing and its not to do with colliders or ur mouse, I realised that I had 2 cameras operating, one main camera and one camera for the player. Because the script is directed at the main camera it wasnt detecting any rays! I changed the code to be camera.current instead of camera.main (but i think a better solution would be to have only ur main camera active I am just too tired to be bothered to change everything rn). Hope this helps!!!

Awesome tutorials! TYSM! 💪

I have issue on this selectionmanager script it gives me null reference object error please help mei to fix this

If you are getting : NullReferenceException: Object reference not set to an instance of an object SelectionManager.Update () (at Assets/Scripts/SelectionManager.cs:21) make sure your camera is tag MainCamera

When i reach the point of adding the component Selection Manager i dint get the Interaction_info_UI, the same when i add the component Interactable object i dont get the Item Name option that appears in your video. it seems that many are having this issue. is there a way to fix this, i tried everything so far, out of ideas...

I got this error what do i do: Assets\Scripts\SelectionManager.cs(9,43): error CS1002: ; expected

Hi Mike I have 1 problem after I write "using UnityEngine.UI" on the top of script I have this error Assets\Scripts\SelectionManager.cs(1,21): error CS1002: ; expected Can you help me?

To raycast to the center of the screen use: Ray ray = Camera.main.ViewportPointToRay(new Vector3(0.5F, 0.5F, 0)); Instead of; Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); The mouse will not always be at the center of the screen.

for the sphere, i just used the UI text and plus sign

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class SelectionManager : MonoBehaviour ... But nothing, in inspector the "Selection Manager" script does not add the "Interaction_Info_UI" option

I have elevated terrain, and every single time they go inside the terrain.... how can I fix this?

{can someone help please} ive ran through this vid before on other projects and the [Selectionmanager] and [interactableobjects] files (WORKED) but now they dont show names and ive ran through it over and over and cant fix it

error i cant seem to fix Assets\SelectionManager.cs(11,5): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)

When my bunnies stop hopping and they should sit still (idle) they kinds slide forward slowly.. then they turn and hop around, then stop and slide slowly.... lol. Any ideas? The rotation on x and z is locked so that bit is solved. They sit still and slide like they're on a skating ring.

at 08:27 when i drag the script to the empty object, i don't get the second row called "Interaction_info_UI". Any solutions to this? I also get this error message when pasting the SelectionManager script code into visual studio: Assets\Scripts\SelectionManager.cs(9,5): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?) I tried doing this with both the TextMeshPro and the normal Text but still the same error

The ground level for my terrain is y position 0, My rabbits y position is 0 as well. For some reason when I start the game, the rabbit's y position will jump up to .25 and stay there while the game runs indefinitely. This problem causes the rabbit to look like it is slightly floating while jumping around. If I use the constraint on the rigidbody to freeze the y position...It messes with the speed of the rabbit and the animation itself. Anyone else experiencing this problem? can't think of any other fixes for it.

On my script i dont have the part where you add text

fantastic video u helped me a lot

im new, and in the newer unity following this tutorial and all is working except the animator section. I cannot for the life of me figure out how to add the isrunning and isdead variables anywhere as mine opens up as read only. any ideas? the bunny stays in the idle animation and moves around per the code, randomly choosing a direction and time, it just doesnt swap from the idle to the running animation. ***edit but leaving for others*** under window/animation/animator parameters is the window to add the isrunning and isdead, it is not in the animation window, its in the animator window, which is activated in the same place. window/animation/animator.

Please can you link your scripts; I like this form of tutorial, you made it verry well

If anyone else is getting “object not set to instance” what worked for me was going to my Camera and changing the tag to Main camera

@Mike's Code where is the Interactable Object script?

9:15 i get this error when i import the script Assets\Scripts\SelectionManager.cs(3,33): error CS0246: The type or namespace name 'MonoBehaviour' could not be found (are you missing a using directive or an assembly reference?)

Hey @MikeSchvedov i keep getting an error that says the file name and class name doesn't match. How do i fix this? (Btw this tutorial is absolutely amazing thank you so much)

Did all like in the tut and got this Assets\Scripts\SelectionManager.cs(10,5): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)

"InteractableObject" not found Solutions within the SelectionManager code?

NullReferenceException: Object reference not set to an instance of an object SelectionManager.Update () (at Assets/Scripts/SelectionManager.cs:19) i have this Problem please tell me How can fix that ?

When trying to get the object name by looking at an object I get this error: "NullReferenceException: Object reference not set to an instance of an object SelectionManager.Update () (at Assets/Scripts/SelectionManager.cs:28)" Does anyone know how to fix this? I've been trying but I just can't figure it out.

am I the only one that the selection manager script doesn't work? It keeps giving me errors when I paste the script.

Hello! Very good video, it helped me a lot, but I have a problem, and that is that when the rabbit stops walking and has to wait while still, instead of staying still, it continues walking but down ( -Y ) and then continues walking in one direction.

hello Mike, great tutorial, I find myself stuck in the third tutorial,minute 9:04, i try to drag the script c# SelectionManager into the empty object of SelectionManager and the new Component is lacking one section that appears in your video, its called Reference to the object, this one doesnt appear in mine. I checked so many times the spelling and reset the scripts, erase them and made them again, restart the project and nothing, i tried all i can, will it still work without it?

This Interaction Info UI its doesnt there in this Script :(

Thanx for amazing tutorial.But i have some problems.When i hit play my character look down at start.And rabbit starts walk and when it stops,it rotates 90 degress and goes idle with its head inside terrain.Then rabbit starts walking again and turns normal.When i hit play and look the game in scene window, my chracters cylender starts game 90 degrees rotated faced to ground, and the when the rabbit ends walking,it is also rotated 90 degrees.When i look inspector, both objects rotation values never change.

Is it not way easier and scaleable to use layers to distinguish between interactable and non-interactable gameobject? you even used this approuch previously for detecting if the player is on the the ground. The physics methods even take in layermask object as params so i would asume this is the way to go no?

Hi Mike, can you help me, if for the third person point of view the coding script part is the same as in the video or something has been changed and I direct it to the object, the writing doesn't appear like the one in the video because I use the third person point of view, is there a solution? Thank you

Really great video! I just encountered a problem. The mouse sensitivity gets reeeeaaally fast every time, I look at my grass. I found out that this is because of the FPS. To solve this problem, you have to set the FPS to a amount, so it cant change. You can do it like this: (Paste this into start method) public int targetFrameRate = 60; // Set the target frame rate Application.targetFrameRate = targetFrameRate; // Set the fixed delta time to ensure consistent physics calculations Time.fixedDeltaTime = 1f / targetFrameRate;

thanks , i have problem about rabbit , in inspector i don't have box cellinder and rigidbody , then in Hierarchy show 2 side box blue one side black

My bunny keeps sinking about 15 less that the normal height and then it goes in the same height in which ever direction, floating bunny. I tried the rigidbody but that did not help much, any suggestions?

Can you help me pls? My rabbit animation is not working. I tried to put them as in the video but still its not working

Please help! The select manager is not working I’m using the old text. Thank you

Anyone else get the error: The type or namespace name could not be found (are you missing a using directive or an assembly reference?) with the ? In the SelectionManager script?

Can somebody help me with the missing text when i point my cursor at a tree?

Assets\Scripts\SelectionManager.cs(28,73): error CS0246: The type or namespace name 'InteractableObject' could not be found (are you missing a using directive or an assembly reference?) how do i fix this??

If the camera fails to find the target! Set the camera as tag main camera ! void Update() { Ray ray; if (Camera.main != null) { ray = Camera.main.ScreenPointToRay(Input.mousePosition); } else { Debug.LogError("Main camera is not found!"); // error log return; // code stop } RaycastHit hit; if (Physics.Raycast(ray, out hit)) { var selectionTransform = hit.transform; if (selectionTransform.GetComponent()) { interaction_text.text = selectionTransform.GetComponent().GetItemName(); Interaction_info_UI.SetActive(true); } else { Interaction_info_UI.SetActive(false); } } } }

We can also limit the distance for ray

Can't get the public GameObject to show in the inspector.

My rabbits flips after run animation and starts floating if colides with another colider :P

when i place crosshair, ITS PIXELIZED AND LOOKS TERRIBLE, even the unity presets looks horibly pixelized, i tried big resolution images, small, different formats, all the canvas settings, image settings in unity, nothing changes the pixalized terrible look of my crosshair white center dot... I am already trying to fix it for 2 hours and i cant figure out whats the problem..........

my rabbit prefabs are clipping inside the terrain any solutions? @Mike's Code

Can I make an rotation animation because it just teleports to the other way

Any fix for some sort of lag spike or frame rate drop when hovering over game objects?

I’m getting the error (interactableObject could not be found (are you missing a using directive or an assembly reference?)) any help?

Hi Ik this is an old video but I can’t seem to get rid of the error (10,5) The type or namespace ‘Text’ could not be found

Amazing tutorials first of all! I have one small problem so far. My Rabbit moves and all that good stuff but wont HOP! driving me crazy! Anyone else?

error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?) How to Fix Help me

Why you use so much code for the direction of the AI. Simple use "transform.localRotation = Quaternion.Euler(0f, WalkDirection*90f, 0f); transform.position += transform.forward * moveSpeed * Time.deltaTime;" instead of using all the switch/case arguments. I'm just a beginner but 4 times the same Code segment isn't looking good for myself.

bro getting error at text line no 7

How did you get art, then ui art, then sphere? They weren't there for me, and I created art and then ui art in that, but how do i get the sphere? Also wondering how you had the rabbits in the hierarchy area

l really need help when l klick right butten and go to "UI" l dont have "text" can someone tell me why

hello there i am having a problem in the SelectionManager Script Firstly the pastebin link isnt working secondly when you drag the interaction_info_UI script to selection manager i am only able to see 1 option which is 'script' where altho we cant edit it but as in your video i am not able to see the refrence section where i can drag the interaction_info_UI. i tried many times tried typing the scrpit by myself, coping scripts from comments, using TextMeshProGUI,new project everything but i am stuck there hope you understand the problem and help me out!!

Hi Mike, I have a question for the selection manager script because it says “the type or namespace“interaction-able object” could not be found” pls help

Great tutorial! My bunny appears for a split second when I first play my game, and then immediately disappears! I'm not sure what I'm doing wrong hah.

Can anyone please write me the whole code of intractable objects

Bit of help here- Assets\Scripts\SelectionManager.cs(9,5): error CS0246: The type or namespace name 'Text' could not be found (are you missing a using directive or an assembly reference?)

It all works after i got a bunch of errors and tried again but my fps got 6 times worse

How to fix my namespace could not be found

Hello, Can you make a story dialogue tutorial? I hope you consider it since I need it for my capstone project.

Instead of this, using navmesh was easier for me for the animal AI.
