Unity-检查播放器是否接地不工作 [英] Unity - Checking if the player is grounded not working

问题描述

我希望播放器接地时播放器跳起来.

I want the player to jump when the player is grounded.

private void OnTriggerStay(Collider other)
{
    if(other.gameObject.layer == 8)
    {
        isGrounded = true;
    }else { isGrounded = false; }
}

生成时播放器处于播音状态.玩家跌落到带有标签Ground的地形后，isGrounded仍然为假.当我将isGrounded手动设置为true并再次跳转时，碰撞后仍然为true.我也不希望播放器在空中跳两次，我可能已经编码了，但是由于出了点问题而无法正常工作.

The player is on air when spawning. After the player falls to the Terrain, which has the tag Ground, isGrounded is still false. When I set isGrounded manually true and jump again, it's still true after collision. I also don't want the player to double jump in the air, which I probaly already coded but is not working because something is wrong.

将OnTriggerStay更改为OnTriggerEnter不会更改任何内容.我希望你能帮助我.

Changing OnTriggerStay to OnTriggerEnter doesn't change something. I hope you can help me.

推荐答案

不要不要使用OnTriggerStay进行此操作.不能保证这是真的.

Do not use OnTriggerStay to do this. That's not guaranteed to be true very time.

在调用OnCollisionEnter时将isGrounded标志设置为true.调用OnCollisionExit时将其设置为false.

Set isGrounded flag to true when OnCollisionEnter is called. Set it to false when OnCollisionExit is called.

bool isGrounded = true;

private float jumpForce = 2f;
private Rigidbody pRigidBody;

void Start()
{
    pRigidBody = GetComponent<Rigidbody>();
}

private void Update()
{
    if (Input.GetButtonDown("Jump") && isGrounded)
    {
        pRigidBody.AddForce(new Vector3(0, jumpForce, 0));
    }
}

void OnCollisionEnter(Collision collision)
{
    Debug.Log("Entered");
    if (collision.gameObject.CompareTag("Ground"))
    {
        isGrounded = true;
    }
}

void OnCollisionExit(Collision collision)
{
    Debug.Log("Exited");
    if (collision.gameObject.CompareTag("Ground"))
    {
        isGrounded = false;
    }
}

在您说它不起作用之前，请检查以下内容:

Before you say it doesn't work, please check the following:

• 您必须将Rigidbody或Rigidbody2D连接到播放器.

如果是Rigidbody2D，则必须使用OnCollisionEnter2D并 OnCollisionExit2D.

If this Rigidbody2D, you must use OnCollisionEnter2D and OnCollisionExit2D.

您必须使用IsTrigger将对撞机连接到播放器 禁用.

You must have Collider attached to the player with IsTrigger disabled.

确保您没有通过以下方式移动Rigidbody 如transform.position和transform.Translate.你必须搬家 Rigidbody和 MovePosition 函数.

Make sure you are not moving the Rigidbody with the transform such as transform.position and transform.Translate. You must move Rigidbody with the MovePosition function.
