Unity的几种旋转方法
接上一节的移动方法，这里列举几种常用的旋转方法
因为和移动用到的工具原理基本类似，不在赘述，感兴趣的同学可以自己将代码挂接在物体上实验
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>

public class QuternionRotate : MonoBehaviour
{
public Transform targetTF;
private void OnGUI()
{
if(GUILayout.Button("让摄像机转向目标物体"))
{
Vector3 direction = targetTF.position - this.transform.position;
this.transform.rotation = Quaternion.LookRotation(direction);
}
if(GUILayout.RepeatButton("使用Lerp控制旋转速度"))
{
Quaternion dir = Quaternion.LookRotation(targetTF.position - this.transform.position);
this.transform.rotation = Quaternion.Lerp(this.transform.rotation, dir, 0.01f);
}
if(GUILayout.RepeatButton("匀速旋转"))
{
Quaternion dir = Quaternion.LookRotation(targetTF.position - this.transform.position);
this.transform.rotation = Quaternion.RotateTowards(this.transform.rotation,dir,1f );
}
if(GUILayout.RepeatButton("right"))
{
this.transform.right = targetTF.position - this.transform.position;
// Quaternion dir = Quaternion.LookRotation(targetTF.position - this.transform.position);
// this.transform.rotation = dir;
}
if(GUILayout.RepeatButton("right2"))
{
Vector3 dir = targetTF.position - this.transform.position;
this.transform.rotation = Quaternion.FromToRotation(Vector3.right, dir);
}
}
}
总结
常用的的旋转方式有如下几种：
- Quaternion.LookRotation
- Quaternion.Lerp
- Quaternion.RotateTowards
- transform.right/up/forward = …
- Quaternion.FromToRotation
