我应该在哪里再次将标志设置为 false？

Question

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

public class Follow : MonoBehaviour
{
    public Transform targetToFollow;
    public Text text;
    public float lookAtRotationSpeed;
    public float moveSpeed;

    private float minMoveSpeed = 0f;
    private bool moveInDistance = false;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        Vector3 lTargetDir = targetToFollow.position - transform.position;
        lTargetDir.y = 0.0f;
        transform.rotation = Quaternion.RotateTowards(transform.rotation,
            Quaternion.LookRotation(lTargetDir), Time.time * lookAtRotationSpeed);

        var distance = Vector3.Distance(transform.position, targetToFollow.position);

        text.text = distance.ToString();

        if(distance > 5f && moveInDistance == false)
        {
            moveSpeed = moveSpeed + 0.5f * Time.deltaTime;
        }

        if (distance > 1.5f && distance < 5f)
        {
            moveInDistance = true;
            moveSpeed = moveSpeed + 0.05f;
        }
        else if (distance < 1f)
        {
            moveSpeed = Mathf.Max(minMoveSpeed, moveSpeed - 0.3f);
        }

        transform.position = Vector3.MoveTowards(transform.position, targetToFollow.position, Time.deltaTime * moveSpeed);
    }
}

The first time the game is running the transform will move faster to the target in this part:

if(distance > 5f && moveInDistance == false)
            {
                moveSpeed = moveSpeed + 0.5f * Time.deltaTime;
            }

Then when the transform has reach close distance to the target he will keep following the target in slower speed in this part:

if (distance > 1.5f && distance < 5f)
            {
                moveInDistance = true;
                moveSpeed = moveSpeed + 0.05f;
            }

The problem is if in the future in the game I will want to change the speed again if the transform will be more then 5 distance from the target. Then where should I change the flag moveInDistance to false again?

Answer 1

You could edit your existing if statement alittle to include what you are after:

if(distance > 5f)
{
  if (moveInDistance == false) {
    moveSpeed = moveSpeed + 0.5f * Time.deltaTime;
  } else {
    moveInDistance = false;
  }
}

Answer 2

You can put moveInDistance before moving logical like

moveInDistance = distance > 1.5f && distance < 5f; // or other condition

if(distance > 5f && !moveInDistance)
{
    moveSpeed = moveSpeed + 0.5f * Time.deltaTime;
}
if (distance > 1.5f && distance < 5f)
{
    moveSpeed = moveSpeed + 0.05f;
}
else if (distance < 1f)
{
    moveSpeed = Mathf.Max(minMoveSpeed, moveSpeed - 0.3f);
}
...

Add example if else for comment

...

float ms = moveSpeed;

if(distance > 5f)
{
    ms = moveSpeed + 0.5f; //move faster
}
else if (distance < 1f)
{
    ms = Mathf.Max(minMoveSpeed, moveSpeed - 0.3f); // move slower
}else {
    //set your ms (movement speed) when follwer is move in distance range if you don’t need default value that equal moveSpeed here
}

// by default if distance in range of 1-5 ms is equal moveSpeed and IsInRange Case

// move object by using ms value
...

Ps. In my opinion I think moveInDistance is not important thing to use in my if-else condition you can check distance range in elseIf statement instead of set to moveInDistance
