Question

现在，我使用F键使其按比例放大或缩小。但是我想添加另一种方法，例如AutoScaling，当在Update中调用它时，它将首先按比例放大，一旦按比例放大，它将按比例缩小，然后再次按比例放大，因此不间断。

缩放脚本：

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

public class Scaling : UnityEngine.MonoBehaviour
{
    public GameObject objectToScale;
    public GameObject lookAtTarget;
    public float duration = 1f;
    public Vector3 minSize;
    public Vector3 maxSize;
    public bool scaleUp = false;
    public Coroutine scaleCoroutine;
    public bool scalingHasFinished = false;

    public void Inits()
    {
        scalingHasFinished = false;
        objectToScale.transform.localScale = minSize;
    }

    public IEnumerator scaleOverTime(GameObject targetObj, Vector3 toScale, float duration, Camera objectToScaleCamera)
    {
        float counter = 0;
        Vector3 startScaleSize = targetObj.transform.localScale;

        while (counter < duration)
        {
            counter += Time.deltaTime;
            targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);

            if (scaleUp)
            {
                var lookPos = lookAtTarget.transform.position - objectToScale.transform.position;
                lookPos.y = 0;
                var rotation = Quaternion.LookRotation(lookPos);
                objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
            }
            else
            {
                var lookPos = lookAtTarget.transform.position - objectToScale.transform.position;
                lookPos.y = 0;
                var rotation = Quaternion.LookRotation(objectToScaleCamera.transform.forward);//SwitchCameras.GetCurrentCamera().transform.forward);//Camera.main.transform.forward);
                objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
            }

            yield return null;
        }

        scalingHasFinished = true;
    }

    public IEnumerator scaleOverTime(GameObject targetObj, Vector3 toScale, float duration, float rotationSpeed)
    {
        float counter = 0;
        Vector3 startScaleSize = targetObj.transform.localScale;

        while (counter < duration)
        {
            counter += Time.deltaTime;
            targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);

            targetObj.transform.Rotate(Vector3.up * rotationSpeed * Time.deltaTime, Space.Self);

            yield return null;
        }
    }
}

以及使用缩放的脚本：

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

public class ObjectsManipulation : UnityEngine.MonoBehaviour
{
    //Camera
    public Camera playerCamera;

    //Scaling
    private bool canScale = true;
    private Scaling scaling;

    //Lights
    public DimLights dimlights;
    private Coroutine lightCoroutine;

    //Colors
    private Colors colors;

    //Rotating
    private bool stopRotation = false;
    private Rotating rotating;

    private void Start()
    {
        scaling = GetComponent<Scaling>();
        scaling.Inits();

        colors = GetComponent<Colors>();
        colors.Start();

        rotating = GetComponent<Rotating>();
    }

    // Use this for initialization
    void Update()
    {
        if (playerCamera != null)
        {
            //Scaling
            if (Input.GetKeyDown(KeyCode.F) && canScale == true)
            {
                Scaling();
            }
        }

        //Rotate
        if (Input.GetKey(KeyCode.R) && !scaling.scaleUp)
        {
            rotating.x += Time.deltaTime * rotating.rotationSpeed;
            scaling.objectToScale.transform.localRotation = Quaternion.Euler(0, 0, rotating.x);
            rotating.keyPressed = true;
        }
        if (Input.GetKeyUp(KeyCode.R))
        {
            rotating.keyPressed = false;
        }

        if (!rotating.keyPressed && !scaling.scaleUp && rotating.rotateBack == false
            && DetectInteractable.detected == false)
        {
            scaling.objectToScale.transform.rotation = Quaternion.LookRotation(playerCamera.transform.forward);
        }

        if (DetectInteractable.detected == true && !scaling.scaleUp && stopRotation == false)
        {
            rotating.x += Time.deltaTime * rotating.rotationSpeed;
            scaling.objectToScale.transform.localRotation = Quaternion.Euler(0, 0, rotating.x);
        }
    }

    public void Scaling()
    {
        //Flip the scale direction when F key is pressed
        scaling.scaleUp = !scaling.scaleUp;

        //Stop old coroutine
        if (scaling.scaleCoroutine != null)
            StopCoroutine(scaling.scaleCoroutine);

        if (lightCoroutine != null)
            StopCoroutine(lightCoroutine);

        //Scale  up
        if (scaling.scaleUp)
        {
            //Start new coroutine and scale up within 5 seconds and return the coroutine reference
            rotating.rotateBack = false;
            scaling.scaleCoroutine = StartCoroutine(scaling.scaleOverTime(scaling.objectToScale, scaling.maxSize, scaling.duration, playerCamera));
            if (dimlights.lightsOnOff == false)
                lightCoroutine = StartCoroutine(dimlights.dimLightOverTime(1, scaling.duration));
        }

        //Scale Down
        else
        {
            //Start new coroutine and scale up within 5 seconds and return the coroutine reference
            rotating.rotateBack = true;
            scaling.scaleCoroutine = StartCoroutine(scaling.scaleOverTime(scaling.objectToScale, scaling.minSize, scaling.duration, playerCamera));
            if (dimlights.lightsOnOff == false)
                lightCoroutine = StartCoroutine(dimlights.dimLightOverTime(0, scaling.duration)); ;
        }
    }
}

在第三个脚本中，我想调用一个将在ObjectsManipulation脚本中使用的方法，也许是相同的方法。缩放比例，也许他会得到一个布尔值；如果布尔值是正确的，则使其自动按比例放大/缩小；如果不正确，则使其自动缩放。使用钥匙。

这是用于测试缩放比例的脚本：

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

public class ScalingTest : MonoBehaviour
{
    ObjectsManipulation om;

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

    }

    // Update is called once per frame
    void Update()
    {
        om.Scaling();
    }
}

例如在Update中可能要做的事情：om.Scaling（false）;用于使用F键和om.Scaling（true）;自动。

我尝试过的更新：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using UnityEditor;
using UnityEngine;

public class ConversationTrigger : MonoBehaviour
{
    public List<Conversation> conversations = new List<Conversation>();

    [HideInInspector]
    public int dialogueIndex;

    [HideInInspector]
    public int conversationIndex;

    private bool triggered = false;
    private bool activateButton = false;
    private DialogueManager dialoguemanager;
    private bool startDialogue = false;

    private void Start()
    {
        dialogueIndex = 0;
        dialoguemanager = FindObjectOfType<DialogueManager>();
    }

    public IEnumerator PlayConversation(int index)
    {
        this.conversationIndex = index;

        if (conversations.Count > 0 &&
            conversations[index].Dialogues.Count > 0)
        {
            for (int i = 0; i < conversations[index].Dialogues.Count; i++)
            {
                if (triggered == false)
                {
                    if (dialoguemanager != null)
                    {
                        dialoguemanager.StartDialogue(conversations[index].Dialogues[i]);
                    }

                    while (DialogueManager.dialogueEnded == false)
                    {
                        yield return null;
                    }
                }
            }
        }
    }

    public void SaveConversations()
    {
        string jsonTransform = JsonHelper.ToJson(conversations.ToArray(), true);
        File.WriteAllText(@"d:\json.txt", jsonTransform);
    }

    public void LoadConversations()
    {
        string jsonTransform = File.ReadAllText(@"d:\json.txt");
        conversations.Clear();
        conversations.AddRange(JsonHelper.FromJson<Conversation>(jsonTransform));
    } 
}

并像这样使用它：

StartCoroutine(conversationTrigger.PlayConversation(0));

conversationTrigger是public ConversationTrigger conversationTrigger;

的地方

但是它根本无法正常工作。它从对话索引0开始，但随后只播放第一个对话句子两次，然后再也不继续进行下一个对话，在这种情况下有两个对话。然后停止。

它应该播放当前对话的所有对话。 PlayConversation方法中有问题。

很抱歉，您的帖子过长并且包含许多冗余代码，因此我没有仔细阅读，这是有关通过脚本制作缩放动画的简单参考。

float minScale; // Minimum scale value
float maxScale; // Maximum scale value
Transform target; // Target to scale

void Update()
{
    float scale = Mathf.PingPong(Time.time, maxScale - minScale) + minScale;
    target.localScale = new Vector3(scale, scale, scale);
}

我如何使对象将不停地自动向上/向下缩放？
