2019-07-11 【UnityTips】代码添加动画事件

1.外部导入得带骨骼(.FBX)得动画事件不能保存，因为是只读得。

2.非只读动画可以在编辑器模式下保存。代码如下：

using UnityEditor;
using UnityEngine;


[ExecuteInEditMode]
public class AnimEventGenerator : MonoBehaviour
{
    public AnimEventGeneratorAsset asset;
    public bool Generate = false;

    private void Update()
    {
        if(Generate)
        {
            Generate = false;
            foreach (var x in asset.clips)
            {
                ResetEvent(x);
            }
        }
    }

    void ResetEvent(AnimClipEvents data)
    {
        int eventCount = data.events.Length;
        AnimationEvent[] eventList = new AnimationEvent[eventCount];

        AnimationClip clip = data.clip;

        for(int i = 0;i < eventCount; i ++)
        {
            AnimationEvent e = new AnimationEvent();
            e.functionName = data.events[i].funcName;
            e.time = data.events[i].frame / clip.frameRate;
            e.intParameter = data.events[i].intParam;

            Debug.Log(e.functionName + " " + e.time + " " + e.intParameter);

            eventList[i] = e;
        }

        Debug.Log(clip.name);


        AnimationUtility.SetAnimationEvents(clip, eventList);

        //EditorUtility.SetDirty(clip);
    }


}

using UnityEngine;


[CreateAssetMenu(menuName = "AnimHelper/AnimEventGeneratorAsset")]
public class AnimEventGeneratorAsset : ScriptableObject
{

    [SerializeField]
    public AnimClipEvents[] clips;

}

using System;
using UnityEngine;

[CreateAssetMenu(menuName = "AnimHelper/AnimClipEvents")]
public class AnimClipEvents : ScriptableObject
{
    public AnimationClip clip;
    public int frameCount;
    public AnimEvent[] events;
}

[Serializable]
public class AnimEvent
{
    public string funcName;
    public int frame;
    public int intParam;
}
