Question

JavaScript => static function MoveTowards(current: float, target: float, maxDelta: float): float;
C# => static float MoveTowards(float current, float target, float maxDelta);

Parameters 参数

current	The current value. 当前值
target	The value to move towards. 要移向的值
maxDelta	The maximum change that should be applied to the value. 应用到该值的最大变化

Description 描述

Moves a value current towards target.

改变一个当前值向目标值靠近。

This is essentially the same as Mathf.Lerp but instead the function will ensure that the speed never exceeds maxDelta. Negative values of maxDelta pushes the value away from target.

这实际上和 Mathf.Lerp相同，而是该函数将确保我们的速度不会超过maxDelta。maxDelta为负值将目标从推离。

JavaScript:

var currStrength: float;
var maxStrength: float;
var recoveryRate: float;
 
function Update() { 
	currStrength = Mathf.MoveTowards(currStrength, maxStrength, recoveryRate * Time.deltaTime); 
} 

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float currStrength;
    public float maxStrength;
    public float recoveryRate;
    void Update() {
        currStrength = Mathf.MoveTowards(currStrength, maxStrength, recoveryRate * Time.deltaTime);
    }
}
