我要评论自定义的插值公式
1
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace ACTBook
{
/**
* static function Repeat (t : float, length : float) : float
* 循环数值t，0到length之间。t值永远不会大于length的值，也永远不会小于0。
* 这是类似于 模 运算符，但可以使用浮点数。
*/
public class Tween1 : MonoBehaviour
{
const float TIME = 3f;
const float DISTANCE = 3f;
void Update()
{
var t = Mathf.Repeat(Time.time, TIME) / TIME;
Debug.Log(t);
/**
* static functionLerp (from : float, to : float, t : float) : float
* 基于浮点数t返回a到b之间的插值，t限制在0～1之间。
* 当t = 0返回from，当t = 1 返回to。当t = 0.5 返回from和to的平均值
*/
transform.localPosition = Vector3.Lerp(new Vector3(0f, 0f, 0f), new Vector3(DISTANCE, 0f, 0f), t);
}
}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace ACTBook
{
public class Tween2 : MonoBehaviour
{
const float TIME = 3f;
const float DISTANCE = 3f;
const float SMOOTH_TIME = 0.2f;
Vector3 mVelocity;
void Update()
{
var t = Mathf.Repeat(Time.time, TIME) / TIME;
var target = Vector3.Lerp(new Vector3(0f, 0f, 0f), new Vector3(DISTANCE, 0f, 0f), t);
/**
* public static Vector3 SmoothDamp(Vector3 current, Vector3 target, ref Vector3 currentVelocity, float smoothTime, float maxSpeed = Mathf.Infinity, float deltaTime = Time.deltaTime);
*
* current The current position.
* target The position we are trying to reach.
* currentVelocity The current velocity, this value is modified by the function every time you call it.
* smoothTime Approximately the time it will take to reach the target. A smaller value will reach the target faster.
* maxSpeed Optionally allows you to clamp the maximum speed.
* deltaTime The time since the last call to this function. By default Time.deltaTime.

*/
transform.localPosition = Vector3.SmoothDamp(transform.localPosition, target, ref mVelocity, SMOOTH_TIME);
}
