我正在尝试使自己的球面跳两次，但似乎有些毛病且迟了，有时跳得比我想要的多或少。我曾尝试观看视频和问题，但它们大多用于2D。
我曾尝试更改条件和值，但要么跳得不如我想的那么快，要么跳得太晚了。
using System.Collections;
using System.Collections.Generic; 使用UnityEngine;
公共类ControllerScript：MonoBehaviour {
public float speed;
public float jumpVelocity;
public float fallMultiplier = 2.5f;
public int currentJump = 0;
private bool isGrounded;
private Rigidbody rb;
void Start()
{
rb = GetComponent<Rigidbody>();
}
void Update()
{
if(isGrounded == true)
{
currentJump = 2;
}
}
void FixedUpdate()
{
float moveHorizontal = Input.GetAxisRaw("Horizontal");
float moveVertical = Input.GetAxisRaw("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
movement = Vector3.ClampMagnitude(movement, 1);
rb.AddForce(movement * speed * Time.deltaTime);
if (Input.GetKeyDown(KeyCode.Space) && currentJump > 0)
{
GetComponent<Rigidbody>().velocity = Vector3.up * jumpVelocity;
currentJump--;
}
else if(Input.GetKeyDown(KeyCode.Space) && currentJump == 0 && isGrounded == true)
{
GetComponent<Rigidbody>().velocity = Vector3.up * jumpVelocity;
}
if (rb.velocity.y < 0)
{
rb.velocity += Vector3.up * Physics.gravity.y * (fallMultiplier - 1) * Time.deltaTime;
}
}
void OnCollisionEnter(Collision collision)
{
Debug.Log("Entered");
if (collision.gameObject.CompareTag("Platform"))
{
isGrounded = true;
}
}
void OnCollisionExit(Collision collision)
{
Debug.Log("Exited");
if (collision.gameObject.CompareTag("Platform"))
{
isGrounded = false;
}
}
}
我希望它能跳两次。
