Curve field in an Editor Window.

using UnityEngine;
using UnityEditor;

public class EditorGUICurveField : EditorWindow
{
    AnimationCurve curveX = AnimationCurve.Linear(0, 0, 1, 0);
    AnimationCurve curveY = AnimationCurve.Linear(0, 0, 1, 1);
    AnimationCurve curveZ = AnimationCurve.Linear(0, 0, 1, 0);

    [MenuItem("Examples/Curve Field demo")]
    static void Init()
    {
        EditorWindow window = GetWindow(typeof(EditorGUICurveField));
        window.position = new Rect(0, 0, 400, 199);
        window.Show();
    }

    void OnGUI()
    {
        curveX = EditorGUI.CurveField(
                new Rect(3, 3, position.width - 6, 50),
                "Animation on X", curveX);
        curveY = EditorGUI.CurveField(
                new Rect(3, 56, position.width - 6, 50),
                "Animation on Y", curveY);
        curveZ = EditorGUI.CurveField(
                new Rect(3, 109, position.width - 6, 50),
                "Animation on Z", curveZ);

        if (GUI.Button(new Rect(3, 163, position.width - 6, 30), "Generate Curve"))
            AddCurveToSelectedGameObject();
    }

    // A GameObject with the FollowAnimationCurve script must be selected
    void AddCurveToSelectedGameObject()
    {
        if (Selection.activeGameObject)
        {
            FollowAnimationCurve comp  =
                Selection.activeGameObject.GetComponent<FollowAnimationCurve>();
            comp.SetCurves(curveX, curveY, curveZ);
        }
        else
        {
            Debug.LogError("No Game Object selected for adding an animation curve");
        }
    }
}

这是可对附加游戏对象 进行动画化的运行时脚本：

// Note that this must be FollowAnimationCurve.cs

using UnityEngine;
using System.Collections;

public class FollowAnimationCurve : MonoBehaviour
{
    public AnimationCurve curveX;
    public AnimationCurve curveY;
    public AnimationCurve curveZ;

    public void SetCurves(AnimationCurve xC, AnimationCurve yC, AnimationCurve zC)
    {
        curveX = xC;
        curveY = yC;
        curveZ = zC;
    }

    void Update()
    {
        transform.position = new Vector3(
                curveX.Evaluate(Time.time),
                curveY.Evaluate(Time.time),
                curveZ.Evaluate(Time.time));
    }
}
