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

[@AcaciaDeveloper]

Just to let everyone know, I'm currently revamping this series in 2020, and I already have the first episode out here: kzbin.info/www/bejne/hp6sgaR9ptVri7s. I strongly recommend following this instead since I've improved my methodology and included better visuals for beginners. Thanks!

[@Jummmpy]

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

[@maxmodjeski8128]

@@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; } }

[@AshTzu]

Great tutorial! Although may I add that in order to prevent the player from moving faster if moving on both the x and z axis you must first normalize the vector then multiply it by the movement speed variable: Vector3 forwardMovement = transform.forward * vertInput; Vector3 rightMovement = transform.right * horizInput; Vector3 moveDir = forwardMovement + rightMovement; moveDir.Normalize(); charController.SimpleMove(moveDir * movementSpeed);

[@karpai5427]

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

[@SubparFiddle]

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.

TO KEEP HIM FACING THE SAME WAY AT ALL TIMES, CHANGE THE " .Self " TO ".World"

[@buddyroach]

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.

[@buddyroach]

thanks

[@TheOnlyArtifex]

This is great! Lightweight character controller that's easy to understand and modify. I prefer this above the standard Unity character controller scripts that you can import. I especially think it's really elegant to use an animation curve as the jump force multiplier, I would've never come up with that. Thanks young Sna... Errr, Acacia!

You could use Mathf.Clamp function to clamp that float between 90 and -90 angle

[@ungordoenapuros]

Awesome, Acacia Developer! Easy, well explained and PRO "feeling" on using it! Thank you so much :)

[@RebootedGaming]

Just a tip, use Input.GetAxisRaw for the mouse so it gets the raw mouse data. On top of that, don't multiply it by Time.deltaTime. For mouse input you shouldn't do that. Because in that case the mouse will only be smooth if you have a locked FPS, which you can of course set in the game engine though generally you don't want to lock the FPS in a game since other people might have a higher refresh rate.

[@drowsy5384]

Nice tips! Will apply in practice

[@comradecheese3535]

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

[@jayit6851]

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.

[@storm5009]

What should you input then?

[@Cappuccino53]

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

[@Fezezen]

If you start falling off the edge of something and press space, you can still jump. To fix this you should initially check if the character is grounded before allowing a jump.

[@antiRuka]

This is actually a feature.

[@u.s7072]

best Unity CC movement series to date

[@JohnWeland]

Awesome tutorial, It would be neat to enable the camera (player look) to be used via controller, player movement is already setup as such

[@rodjownsu]

Loved it, perfect pace for someone who has never used Unity, but is a C# developer, definitely not for new coders. Wonder why the Unity devs decided to go with regular method declaration rather than overriding the inhertied class method for 'start' 'update' etc.. Simpler for new users?

As the camera is always a child of the player body you don't have to assign it every time if you just get the reference using: playerBody = transform.parent.gameObject.transform;

the only thing I don't like about this tutorial is you don't explain the conversion to the Euler Angles and hard lock it to a 90/-90. Honestly you should have used a variable and did a conversion so that people can change it. very few FPS games actually use 90 and -90 its more like -45 and about 70. very few people watching will have clue what to change the 270 and 90 to in order to adjust the clamping.

I missed the boat. The recent version of Unity doesn't have any character controller presets, nor scripts. It's impossible to follow this tutorial without those. My Empty asset isn't even a capsule, but an envelope in the scene list and invisible on the stage. The asset store seems to have only one free character controller package, but that's insanely complex, as if for a full game, and it's third person, when I want first person. I guess I'll try Unreal again.

I just had the same issue.

what I have noticed, if I rotate 360 in one direction several times it finally blocks me from rotating that direction. Not sure what I could have missed, followed script exactly. Anyone else have this problem? Doesn't happen consistently though.

[@Serz__]

UPDATE: I misunderstood how euler rotation worked, I changed the value passed in to ClampXAxisRotationToValue to equal 45.0, and now it clamps properly when I look down. So now i'm just passing in "-clampDown" to ClampXAxisRotationToValue, this is also working with looking up as you might expect. If I set the clamp for the camera looking down to anything other than directly down (-90) the camera freaks out. For example: I have it set to say this: clampDown is set to -45.0f here else if (xAxisClamp < clampDown) //Player looking down { xAxisClamp = clampDown; mouseY = 0.0f; ClampXAxisRotationToValue (clampDown + 180.0f); //Looking directly down is actually 90.0 in euler rotation } The value passed in to ClampXAxisRotationToValue will then be 135.0f I don't really see why that would bug it out, it works if I change the value of clampDown to -90.0f but anything else just breaks
