First Person Controller - Basic Movement and Mouse Input (EP01) [Unity Tutorial] 

Hi guys. I am a developer from Russia, so I apologize for my English. If you have a problem with a character moving diagonally faster than forward, to the right, etc, in the HandleMovementInput, you need to insert this: moveDirection = moveDirection.normalized * Mathf.Clamp(moveDirection.magnitude, 0, walkSpeed);

Subbing for this! This is the first tutorial for a FPS Controller I've found that includes crouching and additional features. This sounds like exactly what I need.

One of the best FPS Input Tutorials on RU-vid, hands down!

Just gonna be honest, you are the GREATEST unity tutorials channel I've ever came across. Whatever I need somehow ends up being in this channel in a way that is most useful, I've been using and modifying (depending on my needs) your pooling system in all of my games, everything you create works like a charm, thank you so much.

Honestly the best, most practical, thorough, and explained unity tutorial I've ever seen. You deserve way more attention.

This is BY FAR the best FPS controller I've seen yet! The adherence to Unity's coding standards and the use of abstraction makes this really easy to implement and extend off of

This is by far the best tutorial Ive run into for this topic. Thank you!

GREATEST unity tutorials channel i ever saw. You got my subscription and hope you will not end this. Love your tutorials, exactly what i need to learn!

A new hope? You have no idea how long I've been searching for a FPS that I can understand and modify

this is THE BEST tutorial I have seen on unity FPS controller. you do a better job than the unity starter asset does of building an fps controller (theirs doesn't even include the ability the crouch, and yours does!). Thanks so much!

Absolutely brilliant!! Thank you for making this!! Have been looking everywhere to see where I can begin to make my own character controller from scratch since I'm very dissatisfied with the ones already out there (free and paid). Understanding how exactly it works makes it a lot easier to tweak it precisely you want it. Great stuff! Subbed!

Please never stop this Series

This is exactly what I was looking for! And delivered in a coherent manner! Thanks.

Just found your channel, really looking forward to the rest of the FPS series and to discover what you have planned to use with it! I did come here for the FPS controller, but seeing how you code and how clean it looks compared to so many others. I am definately going to be doing your NOT space invaders for legal reasons tutorials ;D --- Subbed

Briliant. After just downloading and using FPC's it's great to properly get a handle on them, so i look forward to following the whole series. Thanks

THANK YOU SO MUCH BRO!!! the only FPS tutorial that has worked for me all day AGHHHH

About 3 minutes in "now, I'm going to do this properly". Subbed.

This is an amazing tutorial, It's hard to know where to start with these and do it well because it's so important to the feel of the game. I appreciate how clean the code is I'm learning from that the most. Also in the update loop, I would do "if(!CanMove) return" instead of wrapping the whole function, it does the same thing and is a bit cleaner

great video, really helpful and no errors :) gonna go watch all the other parts now

Great start!

Amazing and professional tutorial and execution, I like the smoothness and coding simplicity (even though I don't understand all calculations :D). I also HATE up/down looking limitations in games. In Hitman 3 when you want to shoot that guy down on the lower floor with style, but you can't because of the 80 degree clamping.

Amazing work this is perfect for what I'm working on right now.

Very helpful, thanks!

Very Clean so far!

Amazing! Please, keep it up!

Thanks, this tutorial will help me with my game a lot!

Insane Video. Thank you very much for it!

Clear and concise. Thank you.

they playlist thumbnail colors are so pretty!

thank you very much............i needed this desperately

YOU ARE A LİFESAVER!! my teacher put the deadline for this weekend and ı have no idea how to create full fps player movement... thanks man

THANK YOU SO MUCH!!! You literally saved my life🥹🥹

If anyone also feels like when they move and stop, that they slide a bit, its because Input.GetAxis grabs the smoothed/lerped value of the input (0 --> 1). Use Input.GetAxisRaw instead and it will be crisper and more responsive.

Thanks for your time for making this tutorial

Great tutorial!

Very easy to follow nice

Great tutorial! Thank you very much!

Very well explained

this is pure gold

Cool!

Men you are awesome. You explain things in a way its so easy to understand me you are one of the few that write code clean and in order. I will follow your channel till the end of time. 🤙🏻🤙🏻 I know its weird to say this but if you need help with spanish for a game or something just Dm me. Have a great day Mike

Would be nice to adapt it for new input system and show how it works with joy pad

Since unity removed the essential fps it created a vacuum and a need so i already created it with the new input system. But I'm always happy to learn something .

allready love it and i havent even started (:

Could you show how to import a Mixamo character and make him walk and jump (and an idle animation) with the new input system? Even the UI changed with it and I'm confused how to do this for future projects.

thank you this helped alot

Great video, your pace of teaching is perfect! One doubt I have is we can get the forward vector of the controller by using transform.forward property right? Is there any reason why you used transform.TransformDirection(Vector3.forward) instead of that?

Hey awesome video btw! Going to scrap the original movement code i did and use yours instead. I do have a couple questions however if thats alright. 1. Will this be able to be updated for many other types of movement. I know you cover some so i will watch them but maybe different ones. 2. Is this able to be used for a character model that is animated? I know you have to rig the animations with inputs and whatever but yeah. Im quite new to c# so would love an in depth rundown of the code you have written for this. I get parts of it but i really would love to fully understand how it works. Anyway great vid and thanks!

Congrats for your new location bro :)

VERY GOOD TUTORIAL, i saw you put private variables so they cant be accesed through a program

Hey I got a problem, when I write vector nothing pops up and an error message appears. Any reason why you think this might be happening?

I am sad only this master piece has 51k view, and happy that I'm one of these.

This was an awesome tutorial!

4:02 lmao brilliant

Thank you very much

Is it possible to make a first person controller similar to the one in outlast or resident evil 7 and village?

This tutorial is superbly explained, however I still need to find how to migrate unity's New Input System to get it to work. I could try to create an InputManager script and get that component in the character controller.

@comp3interactive - I am really struggling to normalize the player's movement when moving at a diagonal so the speed of the player does not go beyond what is defined by walkSpeed and sprintSpeed. With this kind of player controller, how do you typically normalize or clamp that kind of diagonal speed so it is not exceeding the desired value?

i know this tutorial is ages old but how would i go about clamping the Y axis? like looking left and right? since there isn't a distinct variable for it.

16:34 hey just wanted to let you know a small note here, This variable you set was -upper look limit and upper look limit for the lower look limit and the upper look limit which works completely fine but you made two variables lower look limit and upper look limit. Lower look limit wasn't used.

You know, I have went through lots of tutorials videos and let me tell you, Yours is one of the best.. Why not post full length course of Udemy and other platforms? If you have it there then let me know, I would definitely love to purchase full course.

hey I've never used the character controller component before I was used to working with a rigidbody so there is an issue I can't seem to solve... whenever I move the player jitters really hard, and if I get close to wall it climbs it I have no idea why. I followed your tutorial seamlessly

Not sure if I just missed it or not but If anyone is noticing the horizontal speed doesn't change when changing crouch and sprint speeds just do: private void HandleMovementInput() { currentInput = new Vector2((isCrouching ? crouchSpeed : isSprinting ? sprintSpeed : walkSpeed) * Input.GetAxis("Vertical"), (isCrouching ? crouchSpeed : isSprinting ? sprintSpeed : walkSpeed) * Input.GetAxis("Horizontal")); float moveDirectionY = moveDirection.y; moveDirection = (transform.TransformDirection(Vector3.forward) * currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y); moveDirection.y = moveDirectionY; } So that the conditions are also before the horizontal movement.

thanks for the basic tutorial, now I just gotta figure out on my own how to make it react with physics properly, the Character Controller Component can't react with rigid body, so I'm gonna find a bypass to it.

Hey Comp-3, I'm having an issue where my player only moves the camera up and down, not left and right. Any possible fixes for this?

am i able to use the new imput system with this?

So I have implemented the code you have made onto Unity and have tested it out. It works fine but is the player supposed to continuously move on its own? If not, then I would really like to know how to fix this issue.

How to make the Player slide on surfaces with the "ICE" tag?

Now, before I start doing this tutorial, I just need to know - does this character controller allow me to save player position?

Can I ask you something? I I would like when I click a or d the camera rotates. I know how to rotate the camera but I can't understand how to tell the camera to do it with Input.GetAxis("Horizontal"). (I'm pretty new in coding) Thanks for any response

It's best to capture the input in Update and apply the movement in FixedUpdate, since this is related to physics. Otherwise, your movement might get jittery in certain moments.

Does it work the same with the ovr player controller for VR

I'm having an issue with the gravity. I've tried removing the Time.deltaTime that it is multiplied by in the first half of the HandleFinalMovement() function because it is otherwise multiplied by Time.deltaTime twice. This has (sort of) worked, but if there is a better solution, can you please tell me?

Thank you

How do I add movement animations to this script?

please can some respond to this with the code he uses for the first person controller as when i type it it doesnt work please

Hi. Why you called ApplyFinalMovements in update method? Isn't it right to use it in the FixedUpdate method?

For me it keeps saying "The script don't inherit a native class that can manage a script." Can someone help me?

Is there anywhere I can copy your code to do a side-by-side comparison? I feel like I missed something after 7ish tutorials and I can't for the life of me find where I screwed up. 🙃

I have another error, It keeps on going in one direction and doesnt stop, like to the side of my view camera. Please help me with this issue -GlimmerGo0se

I think something wrong with this gravity code. The acceleration needs to be reset when you hit the ground.

can you copy all of the code so we can past it into unity?

Hey, the movement is good, however when you move diagonally you speed up, is there a way to normalize the movement so that when you move diagonally you dont go any faster, thanks!

can you make an inventory system?

Why wasn't Cinemachine used? With it, there wouldn't be a need for Look Parameters.

Cheers for this tutorial, do you ever update the code to accept unities new input system ? i feel like you would do a really good job explaining that confusing (while very useful) mess.

Hi, i dont know why but i cant resolve this problem. When i wrote characterController.Move my visual studio say that was an error because CharacterController doesn't contain a definition of Move. Here is my code: using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class CharacterController : MonoBehaviour { public bool canMove { get; private set; } = true; [Header("Movement Parameters")] [SerializeField] float walkSpeed; [SerializeField] float gravity = 30f; [Header("Look Parameters")] [SerializeField, Range(1, 10)] float lookSpeedX = 2f; [SerializeField, Range(1, 10)] float lookSpeedY = 2f; [SerializeField, Range(1, 100)] float upperLookLimit = 80f; [SerializeField, Range(1, 100)] float lowerLookLimit = 80f; private Camera playerCamera; private CharacterController characterController; private Vector3 moveDirection; private Vector2 currentInput; private float rotationX = 0f; bool isGrounded; void Awake() { playerCamera = GetComponentInChildren(); characterController = GetComponent(); Cursor.lockState = CursorLockMode.Locked; Cursor.visible = false; } // Start is called before the first frame update private void Start() { } // Update is called once per frame void Update() { if (canMove) { handleMovementInput(); handleMouseLook(); applyFinalMovements(); } } void handleMovementInput() { currentInput = new Vector2(walkSpeed * Input.GetAxis("Vertical"), walkSpeed * Input.GetAxis("Horizontal")); float moveDirectionY = moveDirection.y; moveDirection = (transform.TransformDirection(Vector3.forward) * currentInput.x) + (transform.TransformDirection(Vector3.right) * currentInput.y); moveDirection.y = moveDirectionY; } void handleMouseLook() { } void applyFinalMovements() { if (!playerCharacterController.isGrounded) moveDirection.y -= gravity * Time.deltaTime; characterController.Move(moveDirection * Time.deltaTime); } }

one aspect fogotten to mention but you can see it at 14:38 is that you need to add the controller script to the controller parent so it actually knows what to do. i know its a basic thing but it had me stuck a little bit until I saw that.

I also have another problem where when completing the script and dragging it onto the firstpersoncontroller game object inspector, no references come up resulting in a not working code

bruh, I thought that since I was using the new input system my code was broken even though it should have worked because it isn't that hard to get it working with the new input system but at the top I forgot to set can move to true. smh

i just subscribed, however... your not the next Brackeys, your the first Comp-3 Interactive (BTW I mean this in a good way)

When I try to make my left movement snappy by adding some float value in player's current position and then apply that whole value to main movement then console says that cannot transform unity.vector3 to float.

If you could tell me the clamp function is not working and it keeps saying that it needs two arguments

Gravity is not working, original camera controller from URP as child works as basic movement so i can only move camera with using rmb, q and e buttons works exactly like in camera controller from urp

When I fall from a height the gravity seems to be increasing with time

hey i copy pasted your code but the movement becomes faster when walking diagonally, i tried to use normalized but it turned the walk speed to 1 which is waaaay too slow for me, do you have any fix for the boost of speed u get when pressing up and right at the same time? its twice as fast...

Tell me why this happens

just getting into this series, let's see how long i can last!

Yea man, sounds interesting, I'm always using fps controllers and each time I do one, it's different, maybe this would be a good template for me!

"First" :) Another great video Mike, thanks!
