[Unity C#] First Person Controller (E01: Basic FPS Controller and Jumping) 

you did not include jumping in the revamp. is that in ep. 2?

@@Jummmpy He hasn't made episode two yet, and its been months. I don't know if he's gonna even make it, so I just modified the movement script to have the jumping from this tutorial. Here's the code if you want it :) using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { [SerializeField] Transform playerCamera = null; [SerializeField] float mouseSensitivity = 3.5f; [SerializeField] float walkSpeed = 3f; [SerializeField] float gravity = -13f; [SerializeField] [Range(0f, 0.5f)] float mouseSmoothTime = 0.03f; float cameraPitch = 0f; float velocityY = 0f; CharacterController controller = null; [SerializeField] bool lockCursor = true; private bool isJumping; [SerializeField] private AnimationCurve jumpFallOff; [SerializeField] private float jumpMultiplier; [SerializeField] private KeyCode jumpKey; Vector2 currentMouseDelta = Vector2.zero; Vector2 currentMouseDeltaVelocity = Vector2.zero; // Start is called before the first frame update void Start() { controller = GetComponent(); if (lockCursor) { Cursor.lockState = CursorLockMode.Locked; Cursor.visible = false; } } // Update is called once per frame void Update() { UpdateMouseLook(); UpdateMovement(); } void UpdateMouseLook() { Vector2 targetMouseDelta = new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")); currentMouseDelta = Vector2.SmoothDamp(currentMouseDelta, targetMouseDelta, ref currentMouseDeltaVelocity, mouseSmoothTime); cameraPitch -= currentMouseDelta.y * mouseSensitivity; cameraPitch = Mathf.Clamp(cameraPitch, -90f, 90f); playerCamera.localEulerAngles = Vector3.right * cameraPitch; transform.Rotate(Vector3.up * currentMouseDelta.x * mouseSensitivity); } void UpdateMovement() { Vector2 inputDir = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical")); inputDir.Normalize(); if (controller.isGrounded) { velocityY = 0f; } velocityY += gravity * Time.deltaTime; Vector3 velocity = (transform.forward * inputDir.y + transform.right * inputDir.x) * walkSpeed + Vector3.up * velocityY; controller.Move(velocity * Time.deltaTime); JumpInput(); } void JumpInput() { if(Input.GetKeyDown(jumpKey) && !isJumping) { isJumping = true; StartCoroutine(JumpEvent()); } } IEnumerator JumpEvent() { controller.slopeLimit = 90f; float timeInAir = 0f; do { float jumpForce = jumpFallOff.Evaluate(timeInAir); controller.Move(Vector3.up * jumpForce * jumpMultiplier * Time.deltaTime); timeInAir += Time.deltaTime; yield return null; } while (!controller.isGrounded && controller.collisionFlags != CollisionFlags.Above); controller.slopeLimit = 45f; isJumping = false; } }

@@maxmodjeski8128 thank you so much :D

@@Jummmpy No problem!

exactly

it's broken as hell in unity 2018 and up

@@not_herobrine3752 why

@@not_herobrine3752 it is working for me!

@@BreadcrumbMC Oh that's pretty cool! Congratulations and good luck in your project man :)

It makes movement not responsive for me. Player moves for a moment without pressing buttons.

Just leaving this for any aspiring designers, but normalizing your movement vectors isn't always the right thing to do. For example the recent fps DUSK allows you to bunnyhop and move diagonally to build up massive speed and is a ton of fun once you've mastered it. Most new players will never realize this and play the game the normal "intended" way, but by not capping speed the skill ceiling of movement tech is increased exponentially for those who want to play with it.

Oh gosh hahaha. You're the first person to make this joke in one of my newer videos. Glad this helped.

Of course. That's how you learn :P

@@katafalkistasaktyvuokwindo2739 Assuming you go and tinker yourself... Otherwise what you have is a whole pile of frustration.

@@katafalkistasaktyvuokwindo2739 nope he is just too fast. He write the complet script and close it if i have write 5 lines... Im try to make faster and make it faster... also the issues i make faster...and then i can look where this fcking failures are it... nice (learned my english with blueprints (2Jahrs) and Csgo... Cyka Blyad)

I thought it was more like a younger Snape

Dude I was just thinking he sounds like Severus Snape

Большое спасибо!

@Sound Engineer Звукоинженер Я сделал так же, все работает. Проверяй скрипт.

@@FoverosInsanity lol

Yeah. I think same

Planned for a future episode, so yes!

Thanks uwu

public float walkSpeed = 10; public float runSpeed = 20; private float speed; void Start() { } void Update(){ if(Input.GetKey(KeyCode.LeftShift)) { speed = runSpeed; } else { speed = walkSpeed; } if (Input.GetKey (KeyCode.A)) { transform.Translate(Vector3.left * Time.deltaTime * speed, Space.Self); //LEFT } if (Input.GetKey (KeyCode.D)) { transform.Translate(Vector3.right * Time.deltaTime * speed, Space.Self); //RIGHT } if (Input.GetKey(KeyCode.W)) { transform.Translate(Vector3.forward * Time.deltaTime * speed, Space.Self); //FORWARD } if (Input.GetKey(KeyCode.S)) { transform.Translate(Vector3.back * Time.deltaTime * speed, Space.Self); //BACKWARD } } THIS CODE MAKES THE PLAYER AUTOMATICALLY ROTATE IN THE DIRECTION OF MOVEMENT. TO KEEP HIM FACING THE SAME WAY AT ALL TIMES, CHANGE THE " .Self " TO ".World"

same as my suggestion, except mine uses a public variable which can be changed in the inspector. i suppose you could make it a multiplier too instead of just a straight up value. and you could also put all the movement controls as public vars as well too. maybe later on when making a settings menu, with a controls sub menu, you can easily plug in the controller inputs from whatever the player chooses.

thanks

Nice tips! Will apply in practice

what are you multiplying it by then? considering this method won't work without Time.deltaTime

If you don't multiply it by deltaTime the speed of the rotation will be frame rate dependent making faster computers have a faster rotation. That's the point of multiplying by deltaTime.

What should you input then?

Locking FPS is good, because: 1. Update() runs once each frame, so if you have more frames per second script will be run more times, so if it is an Enemy NPC that is shooting if player is close enough, then it will shoot out more bullets, because that line of code will be true more times in a second 2. If you are playing on a 60 or 30 fps and it doesn't change, then it is ok and you might not notice anything, but if FPS is changing non-stop between 30-60, then player will not only notice that, but also it will get annoying, because sometimes character reacts quickly on your controls, when sometimes it takes a little bit more which can make player die quickly. You can also search on google why some games lock their fps

Jumping wasn't working for me either. I couldn't find a place where "JumpInput();" were called. By putting the method call in PlayerMovement(), the character started jumping

@@johanhaggmark3499 thanks man

would suggest rewatching the vid and paying close attention, and if that doesnt work go to the unity forums to see if theres something similar about it

Yeah I have the same issue with moving while jumping

run the game once and then stop, it should come up.

This is actually a feature.

me too

​@@vitoderpro6969 That´s My Player_Move Script: using System.Collections; using System.Collections.Generic; using UnityEngine; public class Player_Move : MonoBehaviour { [SerializeField] private string horizontalInputName; [SerializeField] private string verticalInputName; [SerializeField] private float movementSpeed; private CharacterController charController; [SerializeField] private AnimationCurve jumpFallOff; [SerializeField] private float jumpMultiplier; [SerializeField] private KeyCode jumpKey; private bool isJumping; private void Awake() { charController = GetComponent(); } private void Update() { PlayerMovement(); } private void PlayerMovement() { float horizInput = Input.GetAxis(horizontalInputName) * movementSpeed; float vertInput = Input.GetAxis(verticalInputName) * movementSpeed; Vector3 forwardMovement = transform.forward * vertInput; Vector3 rightMovement = transform.right * horizInput; charController.SimpleMove(forwardMovement + rightMovement); JumpInput(); } private void JumpInput() { if(Input.GetKeyDown(jumpKey) && !isJumping) { isJumping = true; StartCoroutine(JumpEvent()); } } private IEnumerator JumpEvent() { charController.slopeLimit = 90f; float timeInAir = 0f; do { float jumpForce = jumpFallOff.Evaluate(timeInAir); charController.Move(Vector3.up * jumpForce *jumpMultiplier *Time.deltaTime); timeInAir += Time.deltaTime; yield return null; } while (!charController.isGrounded && charController.collisionFlags != CollisionFlags.Above); charController.slopeLimit = 45f; isJumping = false; } }

Hes just experienced, its obviously you who can't keep up. I mean look at the comments around you most are positive. Maybe you're just slow?

Play Video, Watch Video, Pause Video, Write Code, Repeat!!!!!

he is going too slow for me, i need to see it at 2x speed XD

Hey i am running into error with unity where it doesnt let me use my script have you ran into this error to

I just had the same issue. In the PlayerMove script between the lines "timeInAir~" and "yield return null" add: if ((charController.collisionFlags & CollisionFlags.Above) != 0) { break; } The while loop should be catching the collisions from above, but doesn't for some reason. My implementation probably isn't the best, but it seems to work.

I don't understand very good your question but if you want to know how you can see again your mouse you can put this: Cursor.lockState = CursorLockMode.None

press esc and move ur curser to stop

Make sure you didn’t put the camera movement into fixedupdate, always make sure input is done in update. I think that’s what you need to do anyway I’m still new too so yeah.

Simply put, you can't multiply a float (a decimal number) with a string (a portion of text). Check your code!

LMFAO!!!!!

because public means other classes can see and modify it, with a benefit of being able to see and modify it in the inspector. However serialize field means you can see and modify in the inspector exclusively and other classes cant see or modify it. I am unsure but this possibly improves performance and increases security of the variables and lowers the chance of them being tampered with. Hope that helped :D

@@finnbuhse4775 i see,thanks for the awnser

@@Glentgm And that's just best practice. You shouldn't allow access to anything that doesn't need it. So make it private serialized unless you have to make it public.

are you sure that you typed "Cursor.lockState = CursorLockMode.Locked;" in the Start method?

You can adjust the speed of all youtube videos by clicking on the settings gear in the right corner. It has helped me a lot and I hope it helps you.

@@spazticjest just go to the seetings, set the video speed to 0.5 and enjoy a Unity lesson by Severus Snape at normal speed

Notice how the op said " how and why", the "why" being an important part of the comment. Simply slowing the video down will not explain the " why" for the those seeking more in depth explanations; it just provides for them, what they consider to be, complicated concepts at a slower speed.

Update isn't exact, it's locked to frame rate. So if you rotate the Camera fast enough, the Camera will overshoot the bound but your clamp value will be clamped. So it will slightly offset your rotation range everytime. Do it enough times and you can flick the camera around.
