为什么我的角色/相机在Unity 2d中口吃？

Question

Ever since I've added this new camera script, my character (which the camera is trying to follow) keeps on stuttering when it is moving. If I keep the character still, then it won't stutter anymore.

Here's a video of what I mean.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class CameraFollow : MonoBehaviour
{   
public Transform lookat;

private bool smooth = true;
private float smoothSpeed = 0.1f;
private Vector3 offset = new Vector3 (0, 0, -6.5f); 

void LateUpdate() {

    Vector3 desiredPosition = lookat.transform.position + offset;

    if (smooth) {
        transform.position = Vector3.Lerp (transform.position, desiredPosition, smoothSpeed);
    } else {
        transform.position = desiredPosition;
    }

}

}

Please help - it's driving me crazy! EDIT: Also ignore the error at the bottom - it's part of something else I'm working on.

EDIT2: Never mind, turning on interpolation in rigidbody2d fixed it! Thanks for your help!

Answer 1

The studdering is not caused due to the Update() function!

The stuttering is probably caused because of the Lerp() function, you would rather use the SmoothDamp() .

Like this

transform.position = Vector3.SmoothDamp(transform.position, desiredPosition, smoothSpeed);
