如何在编辑器中通过脚本创建动画片段

unity3d c#

我想用Unity中的编辑器创建一个AnimationClip。

I previously got an answer 关于如何使用MonoBehavior实现这一点。

然而,当我在编辑器中运行以下代码时,我得到了一个错误。

using UnityEngine;
using UnityEditor;
using System.Collections;
using System;
using System.IO;
using System.Text;

public class ExampleWindow : EditorWindow {

    private float m_start_time = 0.0f;
    private float m_start_value = 0.0f;
    private float m_end_time = 5.0f;
    private float m_end_value = 10.0f;

    public GameObject cubeObject;

    [MenuItem("Window/ApplyAnimation")]
    public static void ShowWindow ()
    {
        GetWindow<ExampleWindow>("ApplyAnimation");
    }

    void OnGUI ()
    {
        GUILayout.Label("Apply animation", EditorStyles.boldLabel);

        if (GUILayout.Button("Apply animation"))
        {
            ApplyAnimation();
        }
    }

    void ApplyAnimation()
    {
        Animation animation = GetComponent<Animation> ();

        cubeObject = GameObject.Find("Cube");

        if (!animation)
        {
            cubeObject.AddComponent<Animation>();
        }
        AnimationClip clip = new AnimationClip();
        AnimationCurve curve = AnimationCurve.Linear(m_start_time, m_start_value, m_end_time, m_end_value);
        clip.SetCurve("", typeof(Transform), "localPosition.x", curve);
        animation.AddClip(clip, "Move");
        animation.Play("Move");
    }

}

以下是错误消息

Assets/ExampleWindow.cs(35,31): error CS0103: The name 'GetComponent' does not exist in the current context

如何修复此错误?

在获取之前交换通道并添加立方体对象:

cubeObject = GameObject.Find("Cube");
        
Animation animation = cubeObject.GetComponent<Animation>();

在“播放”按钮之前在资源文件夹中创建动画。回顾动画cntl+6>>播放:

void ApplyAnimation()
{
    cubeObject = Selection.activeGameObject;

    if (!cubeObject) return;
    
    var _animation = cubeObject.GetComponent<Animation>();

    if (!_animation) _animation = cubeObject.AddComponent<Animation>();

    var clip = new AnimationClip();
    var curve = AnimationCurve.Linear(m_start_time, m_start_value, m_end_time, m_end_value);
    clip.SetCurve("", typeof(Transform), "localPosition.x", curve);

    clip.name = "Move"; // set name
    clip.legacy = true; // change to legacy

    _animation.clip = clip; // set default clip
    _animation.AddClip(clip, clip.name); // add clip to animation component

    AssetDatabase.CreateAsset(clip, "Assets/"+clip.name+".anim"); // to create asset
    _animation.Play(); // then play
}
