Question by PercyCreeper123 · Jan 19 at 12:44 PM · inputlagproblem during runtime

Project in play mode creates a lagspike when pressing/releasing a key

Hi, as the title sais, my problem is that while I´m in play mode, everytime I press a key on my keyboard, the project laggs for half a second. This also happens when releasing the key again, but not when holding it down. My guess is that it is caused by my Character Controller, but I´m not sure. Here is said PlayerController:

using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { [SerializeField] Transform playerCamera = null; [SerializeField] float mouseSens = 3.5f; [SerializeField] float speed = 6f; [SerializeField] float smoothTime = 0.2f; [SerializeField] float gravity = -9.81f; [SerializeField] float jumpHeight = 2f; [SerializeField] bool lockMouse = true; float camRotation = 0f; float veloY = 0f; Vector2 currDir = Vector2.zero; Vector2 currDirVelo = Vector2.zero; Vector2 currMouseDelta = Vector2.zero; Vector2 currMouseDeltaVelo = Vector2.zero; CharacterController controller = null; void Start() { controller = GetComponent<CharacterController>(); if(lockMouse) {Cursor.lockState = CursorLockMode.Locked;Cursor.visible = false;} } // Update is called once per frame void Update() { UpdateLook(); UpdateMove(); } void UpdateLook() { Vector2 targetMouseDelta = new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")); currMouseDelta = Vector2.SmoothDamp(currMouseDelta, targetMouseDelta, ref currMouseDeltaVelo, smoothTime/10f); camRotation -= currMouseDelta.y * mouseSens; camRotation = Mathf.Clamp(camRotation, -90f, 90f); playerCamera.localEulerAngles = Vector3.right * camRotation; transform.Rotate(Vector3.up * currMouseDelta.x * mouseSens); } void UpdateMove() { Vector2 targetDir = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical")); targetDir.Normalize(); currDir = Vector2.SmoothDamp(currDir, targetDir, ref currDirVelo, smoothTime); if(controller.isGrounded) {veloY = 0f;} if(Input.GetButtonDown("Jump") && controller.isGrounded) { veloY = Mathf.Sqrt(jumpHeight * -2f * gravity); } veloY += gravity * Time.deltaTime; Vector3 velocity = (transform.forward * currDir.y + transform.right * currDir.x) * speed + Vector3.up * veloY; controller.Move(velocity * Time.deltaTime); } }

One weard thing to me is that these lag spikes do not occur in other projects which use a similar way to get an input to move a player. Here is one example of a project that did not cause any lagspikes to me.

I´m using Unity 2020.3.25f1

Any help is appreciated, even if it does not help ;)

Sorry for the messed up look of the code... It looked normal for me before publishing my question...
