Question

因此，我一直在研究脚本，以使球以恒定的速度在X轴上移动，但也可以控制。当我按空格键跳。除非我按5至6次按钮，否则它不会跳。第一次跳球后，如果反复轻按空格键，球会跳起来，但是如果不理会球滚动，然后尝试再次跳球。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);
    }
}

Answer 1

有一种更好的方法：

Rigidbody body = GetComponent<Rigidbody>(); 

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