接下来是演示如何使用的案例脚本：
using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;
public class playerTest : MonoBehaviour {
public Animator anim;
private Vector3 targetPos;
//private Recorder record;
private bool isReplay = false;
void Awake()
{
anim = GetComponent<Animator>();
//record = new Recorder(gameObject);
}
void Start()
{
}
void Update()
{
}
private void OnGUI()
{
if (GUILayout.Button("Record"))
{
//record.StartRecord();
Recorder.Record(new List<GameObject>() { gameObject });
}
if (GUILayout.Button("Play"))
{
isReplay = true;
//anim.enabled = false;
//record.Play(0.1f,()=> { });
Recorder.ReplayRecord(0.5f, () =>
{
Debug.Log("All OK!!!");
});
}
if (GUILayout.Button("Run1"))
{
anim.SetTrigger("Run01");
targetPos = new Vector3(5f, 0, 3f);
}
if (GUILayout.Button("Run2"))
{
anim.SetTrigger("Run02");
targetPos = new Vector3(3f, 0, 6f);
}
if (!isReplay && Vector3.Distance(transform.position, targetPos) > 0.1f)
{
transform.LookAtXZ(targetPos);
transform.position += (targetPos - transform.position).normalized * 4f * Time.deltaTime;
}
}
}
SupportBehavior工具是一个工具类，主要是延时功能。地址：https://blog.csdn.net/qq_32225289/article/details/84952406
