Unity 3D C＃Player移动跳跃错误

Posted 2021-04-23

所以我一直在制作一个脚本，让球在x-asis上以恒定速度移动，但也可以控制。当我按空格键跳转。除非按下按钮5到6次，否则它不会跳转。如果你第一次跳球，如果你反复敲击空格键它会跳，但是如果你不管它并让它滚动然后再尝试跳。它不会让你。我很困惑。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Speed : MonoBehaviour
{
    public float sspeed = 7.0F;
    public float jumpSpeed = 8.0F;
    public float gravity = 20.0F;

    private Vector2 moveDirection = Vector2.zero;

    void Start()
    {

    }
    void Update()
    {
        if (GetComponent<CharacterController>().isGrounded)
        {
            moveDirection = new Vector2();
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= sspeed;
            moveDirection.x = sspeed;
        }
        else if (GetComponent<CharacterController>())
        {
            moveDirection.x = gravity;
        }

        moveDirection.x -= gravity * Time.deltaTime;
        GetComponent<CharacterController>().Move(moveDirection * Time.deltaTime);
        CharacterController player = GetComponent<CharacterController>();

        if (GetComponent<CharacterController>().isGrounded)
        {
            moveDirection = new Vector2();
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= sspeed;

            if (Input.GetKeyDown("space"))
            {
                moveDirection.y = jumpSpeed;
            }
        }

        moveDirection.y -= gravity * Time.deltaTime;
        GetComponent<CharacterController>().Move(moveDirection * Time.deltaTime);
    }
}

答案

有一个更好的方法：

Rigidbody body = GetComponent<Rigidbody>(); 

if(Input.GetKeyDown(KeyCode.Space)){
    body.AddForce(transform.up*jumpSpeed);
}

另一答案

试试这个吧

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ConstantMoveByX : MonoBehaviour
{
    [SerializeField]
    private float constantSpeed = 10.0f;
    [SerializeField]
    private float jumpForce = 25.0f;
    [SerializeField]
    private float gravity = 9.8f;

    private CharacterController characterController;
    private Vector3 moveDirection = Vector3.zero;

    private void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    private void Update()
    {
        if (characterController.isGrounded)
        {
            moveDirection = Vector3.right * constantSpeed;
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection = moveDirection * constantSpeed;

            if (Input.GetKeyDown(KeyCode.Space))
            {
                moveDirection.y = jumpForce;
            }
        }

        moveDirection.y = moveDirection.y - (gravity * Time.deltaTime);
        characterController.Move(moveDirection * Time.deltaTime);
    }
}
