使用Vector3.up让玩家做超过1次的跳跃

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float jumpForce = 5f;
    private bool isJumping = false;
    private int jumpCount = 0;
    private int maxJumps = 2; // 允许的最大跳跃次数

    void Update()
    {
        if (Input.GetButtonDown("Jump") && jumpCount < maxJumps)
        {
            Jump();
            jumpCount++;
        }
    }

    void Jump()
    {
        if (!isJumping)
        {
            isJumping = true;
            GetComponent<Rigidbody>().AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
        }
    }

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.CompareTag("Ground"))
        {
            isJumping = false;
            jumpCount = 0; // 重置跳跃计数器
        }
    }
}

void OnCollisionEnter(Collision collision)
{
    if (collision.gameObject.CompareTag("Ground"))
    {
        isJumping = false;
        jumpCount = 0; // 重置跳跃计数器
    }
}
