unity3D爬楼梯代码

以下是一个简单的 Unity3D 爬楼梯的代码示例：

using UnityEngine;

public class StairClimber : MonoBehaviour
{
    public float stepHeight = 0.3f;
    public float stepDuration = 0.2f;
    public float stepDistance = 1.0f;
    public float climbSpeed = 2.0f;

    private Vector3 targetPosition;
    private bool isClimbing = false;
    private float climbStartTime;

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) && !isClimbing)
        {
            StartClimbing();
        }

        if (isClimbing)
        {
            float t = (Time.time - climbStartTime) / stepDuration;
            transform.position = Vector3.Lerp(transform.position, targetPosition, t * climbSpeed);

            if (t >= 1.0f)
            {
                isClimbing = false;
            }
        }
    }

    private void StartClimbing()
    {
        targetPosition = transform.position + (transform.up * stepHeight) + (transform.forward * stepDistance);
        climbStartTime = Time.time;
        isClimbing = true;
    }
}

这个脚本可以附加到一个角色或其他对象上，使它能够爬上楼梯。当按下空格键时，对象将开始爬行，每个步骤将持续一定的时间，直到到达目标位置。你可以通过调整公共变量的值来改变步骤的高度、速度和距离。
