Mathf.InverseLerp

パラメーター

戻り値

float Percentage of value between start and end.

説明

[a, b] の範囲内で補間する値 value を生成する線形パラメーター t を計算します。

The a and b values define the start and end of the line. Value is a location between a and b. Subtract a from both a and b and value to make a', b' and value'. This makes a' to be zero and b' and value' to be reduced. Finally divide value' by b'. This gives the InverseLerp amount.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public float walkSpeed = 5.0f;
    public float runSpeed = 10.0f;
    public float speed = 8.0f;

    void Start()
    {
        float parameter = Mathf.InverseLerp(walkSpeed, runSpeed, speed);
        Debug.Log("InverseLerp: 5, 10, 8 = " + parameter);
    }
}
