There is an error with the auto braking, if your stopping distance is below ~3 unity will sometimes forget about it altogether and you will end up inside the sphere. Just turn off autobraking when you set the stopping distance, and turn it back on when you unfocus.

[@GausRothTutorials]

Awesome tutorial! I managed to convert this to work on my 2D game. The interactable script is the same but the player controller script is pretty much all changed.

[@dylloop]

Ran into an interesting error thought i would share the fix. sometimes i would get an error saying "Look rotation viewing vector is zero." it would just spam the console. Usually .normalized should make it so this doesnt happen but if the number is really small unity makes it 0 instead of 1/ so to fix this I added an if statement before the look rotation and it ended up looking like this. void FaceTarget () { Vector3 direction = (target.position - transform.position).normalized; if (direction.x != 0f || direction.z != 0f) { Quaternion lookRotation = Quaternion.LookRotation(new Vector3(direction.x, 0f, direction.z)); transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * rotationSpeed); } }

[@fonsly5077]

I can officially confirm that the player controller has a Fundamental bug that is preventing the game from acting in 2021. I even took the code and modified it to be exactly like his on github. DO NOT BOTHER TRYING TO FINISH THIS IN 2021. Basically the error that fundamentally prevents some of the advanced parts of the controller code, and will not interact with the object. I am going to try and download the finished version from git, and see if that even works.

[@darkdoom907]

9:55, check if player is in range

[@ChumperDumper]

Thought I should mention that when you set a boolean, you don't have to set it to false. A bool will always default to false when being declared. You should only initialize it if you want to set it to true by default. Keeps the code a bit cleaner.

[@SubjektDelta]

Setting it to false makes it easier to understand for others! And it doesn't muddle up the code that much..

[@dan_kotsu]

So i have my code exactly the way Brackeys has it but for some reason when i right click on the sphere it will not move to it but it will focus and recognize the object, any ideas?

Wouldn't it be more robust to implement an interactable interface? That way interactable functionality can be added more flexibly without having to derive from the same class.

[@aza1ization]

sir, i feel like i've given up on all this coding and unity. its just too hard. i spend hours on end just trying to understand a function and it wont come to me. i dont know what to do

[@arthos4551]

aza1ization i highly suggest learning a base language first. Something like C/C++ or java. From there you will get a basic understanding of the fundamentals like loops, arrays, pointers, functions, ect. If you're having trouble with just knowing what function in the Unity libraries does then i suggest finding a compilation of explanations or backtrack to the original implementation of the function and see if the developers left any comments in their code with explanations. Sometimes even the software will explain what the function does if you hover over it but i don't think unity does this.

[@mahmoudshatnawi6122]

All good programmers felt the same at some point. I can help you with something if you want

[@ResoCoder]

While I wouldn't suggest to hop into another language if you want to do Unity development, basic understanding of the language is much needed. Then just sit down and code. Really... I know it may sound weird but at some point it's just gonna "click" and you will begin to understand everything. So just "trust the process"! Stick to what you're doing, push forward and you will be really glad that you didn't give up later down the line. Good luck!

[@elofkarlsson6343]

Keep at it! There're no shortcuts to this. Programming is, or at least was for me, something that you just have to put the hours in programming yourself. Eventually it'll click. I gave up several times, but allways came back. Then during one of my attempts, it clicked.

[@gmfCoding]

A function or method (they are the same thing) is something you can call/invoke to what i would call manipulate variables. All programming is, is checking what a variable is and or setting a variable to something. Nothing more nothing less. If you wan't you can think of a function as like a book (that you made or someone else made), every-time you read the book (call the function) it does what you/someone wrote in it. Function's are designed to cut down on code repetition. Functions make your game/application smaller in size. Hopefully this can clear things up. I have self taught my self programming since 13, i have been programming for 5-ish years now however most of that time wasn't programming. It's was only when i discovered Unity was when i start to get "Good". *Patience is also a massive key in learning programming, without it you are sure to fail.*

[@mshaheerhaider]

I noticed something in your tutorials, you choose the hardest way to do things. I know you love maths and complexity but you should keep it simple.

[@user-th8nx4cp7w]

He is already doing things in the most efficient and easy way for people to understand, I could make this tutorial way harder but the code run faster. I do know what you mean by "easy", but the code will be not clean, not efficient and run slow.

[@SovakaKindred]

Question: Why did you not use 'Transform.LookAt' instead of creating your own version of it?

[@tylerguitar75]

Transform.LookAt would snap the rotation. Doing it his way with slerp lets us do it smoothly at our specified speed

[@roganjosh6220]

for anyone wanting to do this by the end of the year who've just started, don't bother with raycasts and shit. just use a collision and pass the collider to the player script using OnTrigger2D round an area, and cast the collider object as the player script.

[@hexadecimals1093]

how do i do that

[@roganjosh6220]

@@hexadecimals1093 if you put a big collision box ONTOP of your actual collision box for a door/chest/thing-to-interact-with, you can check in your player script for "OnTriggerEnter2D" (tick isTrigger for collider). This means you can store the object that you can interact with from there (look up Collision structure)

***SOLVING THE PROBLEM OF INTERACTION WITH THE SPHERE *** Unfortunately, this was not mentioned in this video and is very important for the correct operation of the script!

Or you can remove the movementmask variable on your "if" argument since that is the one trapping the layermask.

[@moonlightshadowpony]

thank you! i just spent 30 minutes looking through my code because i was certain i missed a semicolon or accidentally misspelled a variable or something to make my right mouse button not work.

[@chenariana3482]

But it still wont stop when the player reach the edge of the radius of the interactable object..

[@SamNBCA]

I think I broke something, after i right click on the sphere, If I right click on the terrain I don't move anymore. *Update: I think i found the issue, in PlayerController.CS in the press right mouse button down logic... I commented out : if (interactable != null) { SetFocus (interactable); } That seemed to resolve the issue.

[@mikedupree2690]

Same issue. If you comment that line out you no longer interact with the Object.. Curious what I did wrong

[@SamNBCA]

If you look at this script github.com/Brackeys/RPG-Tutorial/blob/master/RPG%20Project/Assets/Scripts/PlayerController.cs * * Note: ignore lines 25 & 26 (it's for a later tutorial) It looks like the functionality has changed on the right cliick, there is no... motor.MoveToPoint(hit.point); it's only part of the left click, looks like left is going to be for moving and right is going to be for picking up items. So remove motor.MoveToPoint(hit.point); from your right click and you should be caught up (it's likely something that is addressed in a future tutorial. hope that helps.

[@skarrlive1616]

bro i have the same issue i need ur help apparently unity says NullReferenceException: Object reference not set to an instance of an object PLayermotor.FaceTarget () (at Assets/Scripts/PLayermotor.cs:48) PLayermotor.MoveToPoint (Vector3 point) (at Assets/Scripts/PLayermotor.cs:30) PlayerController.Update () (at Assets/Scripts/PlayerController.cs:25)

[@chicc2826]

yay! we made it through!

[@mehmetizmirli9067]

Please keep doing it. This is exactly whar i need :o :D Edit: Specially animating part.

[@bernardb2348]

hey buddy. I dont think you should put the stopping distance in the stop followind target() back to 0f. You should always want your stopping distance to be the same (non changing). just saying. THX for the amazing videos

[@jakespencer1993]

Code seems to match perfectly but i can not left click on the item, focus on it, and have him move to it. It focuses, just will not move.

[@dan_kotsu]

I have the same issue. Pretty frustrating.

[@maximusthegreatest]

This works up until you put the FollowTarget logic inside a check to see if Focus != null like this: void SetFocus(Interactable newFocus) { if(newFocus != Focus) { if (Focus != null) { print("Running focus"); Focus.OnDefocused(); Focus = newFocus; motor.FollowTarget(newFocus); } } It wil pass the first check but Focus is equal to null because its not declared with anything. So it wont activate the FollowTarget method. It instead goes to newFocus.OnFocused(transform); which doesnt return anything hence Focus will never be not null. Any ideas on how to fix?

[@committedcoder3352]

hi, can't wait to watch.

[@committedcoder3352]

btw, you interupted me watching a vid on nuka cola, but this is way better so dont feel bad

[@tombecker1197]

Assets\scripts\PlayerClick.cs(24,27): error CS1061: 'fallowplayer' does not contain a definition for 'ScreenPointToRay' and no accessible extension method 'ScreenPointToRay' accepting a first argument of type 'fallowplayer' could be found (are you missing a using directive or an assembly reference?)

[@immortalhamster1645]

When your watching a tutorial series for the inventory and you have to make sure that your FPS controller doesn’t moving the wrong direction because you shot an interactable.

[@adrianc5074]

Great tutorials! I have though a problem, I cannot select the Spehere on the Default Layer, it only works if it is part of the Ground layer. It eludes me why it is like that, from your video it looks fine on the Default layer. The movement mask seems to have no impact on your interactables.

[@clunkerz3953]

I had the same problem as well and i just made a different layer called Interactables and on player movement mask i made it so that it had Ground and Interactables selected, seems to work fine now but im not sure if it will break in the future. hopefully that helps ya!

[@clunkerz3953]

Hey so i messed around with it further and if you copied the if statement for movement like he did and only changed the GetMouseButtonDown, make sure to delete the movementMask in the arguments of the if statement for physics.Raycast! this will make it so that when checking for interactables it wont be solely be based on the ground layer and check any object in the scene.

[@UsernameNULL755]

One question - why make an Intractable parent class for all the stuff that probably has nothing else in common? Doesn't it make more sense to make something like an interface? Is that even possible in unity? I'm coming from UE4 perspective, so this approach with attaching scripts to objects is still weird to me.

[@sgyffysgyffy4736]

Alright! Great work on your videos! If you were to make text-based Unity tutorials, I would gladly become a Patreon supporter. Unity is in dire need of more HQ text-based tutorials.

[@kugelrilli4843]

i cant add the interactable script to the interactable the error says "Cant add script behaviour AssemblyInfo.cs. The script needs to derive from MonoBehaviour!" pls help

[@FreeLeaks]

Make sure at the very top the 'public class *a name here* : MonoBehaviour{' is set to 'public class *AssemblyInfo* : MonoBehaviour{'

[@QDurlstonP]

Additional Request for the future, is there any chance you could look into performance management on completion of this project? I'm talking about how you'd swap between low and high poly models, terrain and assets based on distance (whether to use Async-scenes or to run checks through script(s) checking object distances. I get this doesn't really fit to the scale of the project (at least the intro footage shows a relatively small environment, such that scene management probably won't be a problem). Just a request for features that may have been forgotten/left out of this tutorial due to its scope. I look following this tutorial in the near future. Keep up the awesome work!

[@ChumperDumper]

Take a look at tutorials for Occlusion Culling and LOD (Level of Detail). Both of these are built into Unity (although there are slight shit tbh when it comes to clean use of them). I don't fully understand why you would want to use Async to check object distance? If you want to keep it efficient, run it on a separate thread. :P

[@qwerty81808]

Running it on a separate thread would, by definition, make it asynchronous.

[@QDurlstonP]

ChumperDumper when I first started learning about scene management, I wound up on a tutorial suggesting breaking up a scene through Async-loading different sections of the scene based off hitboxes (so for example, loading the other side of a bridge as you start to cross it, removing the scene where you came from as you leave the far side of the bridge). It's just one way of keeping the object-count low in a large world. I hadn't heard of the Occlusion Culling and LOD settings built into Unity before reading your comment (I honestly thought there was no built-in features for asset-detail management), so I'll go research them now. Thanks!

[@willygamedev8144]

At 8:16. Is it possible to user Euler angles instead of Quaternion.Lookrotation? (line 52) Quaternion lookRotation = Quaternion.Euler(new Vector3(direction.x, 0f, direction.z)); (line 53) transform.rotation = Quaternion.Slerp(transform.rotation, lookrotation, Time.deltaTime * 5f);

[@fullmetalairsoft8586]

Getting an error with motor "Assets\Scripts\Movement.cs(12,12): error CS0246: The type or namespace name 'Motor' could not be found (are you missing a using directive or an assembly reference?"

[@rodriguezgino7044]

On the rotation part, my game got kinda weird. As I was moving the sphere around the character, I began to notice that the character did not rotate. It rotates when I move with the left-click but not when following the interactable with right-click. Any help would be greatly appreciated.

[@rodriguezgino7044]

Never mind my request, hahaha. I completely forgot to add FaceTarget(); to the void Update() section.

[@YourFutureCoach]

The problem is he went over that bit so fast that is very easy to miss. I missed it too.

[@aidendawes3560]

Hi Brakeys, your tutorials are awesome, I learn so much!!! Please can you do a save system tutorial?

[@tylerguitar75]

I know this wouldnt be as good as a tutorial, but you can look up the unity docs on XML output as a starting point. E.g. output your player's transform to a file and read it on start.

[@pitaya4151]

Y'all, check out PlayerPrefs. It's super easy!
