c# - C#中的双跳

我想制作2D平台游戏，以使我的角色能够翻倍。

使用此代码，我的角色可以双跳，但根据我按下跳跃按钮的速度，第二次跳跃将使角色跳跃的速度比我等待按下跳跃按钮的速度高两倍。

我该如何做才能使第二跳不高于第一跳？

[SerializeField] float maxSpeed = 10f;              // The fastest the player can travel in the x axis.
[SerializeField] float jumpForce = 400f;            // Amount of force added when the player jumps.

[Range(0, 1)]
[SerializeField] float crouchSpeed = .36f;          // Amount of maxSpeed applied to crouching movement. 1 = 100%

[SerializeField] bool airControl = false;           // Whether or not a player can steer while jumping;
[SerializeField] LayerMask whatIsGround;            // A mask determining what is ground to the character

Transform groundCheck;                              // A position marking where to check if the player is grounded.
float groundedRadius = .2f;                         // Radius of the overlap circle to determine if grounded
bool grounded = false;                              // Whether or not the player is grounded.
Transform ceilingCheck;                             // A position marking where to check for ceilings
float ceilingRadius = .01f;                         // Radius of the overlap circle to determine if the player can stand up
Animator anim;                                      // Reference to the player's animator component.

int maxNumberOfAirJumps = 1;                        // Number of times the player can jump in the air
int numberOfAirJumpsLeft = 0;



void Awake()
{
    // Setting up references.
    groundCheck = transform.Find("GroundCheck");
    ceilingCheck = transform.Find("CeilingCheck");
    anim = GetComponent<Animator>();
}


void FixedUpdate()
{
    // The player is grounded if a circlecast to the groundcheck position hits anything designated as ground
    grounded = Physics2D.OverlapCircle(groundCheck.position, groundedRadius, whatIsGround);
    anim.SetBool("Ground", grounded);

    // Set the vertical animation
    anim.SetFloat("vSpeed", rigidbody2D.velocity.y);
}


public void Move(float move, bool crouch, bool jump)
{
    // If crouching, check to see if the character can stand up
    if(!crouch && anim.GetBool("Crouch"))
    {
        // If the character has a ceiling preventing them from standing up, keep them crouching
        if( Physics2D.OverlapCircle(ceilingCheck.position, ceilingRadius, whatIsGround))
            crouch = true;
    }

    // Set whether or not the character is crouching in the animator
    anim.SetBool("Crouch", crouch);

    //only control the player if grounded or airControl is turned on
    if(grounded || airControl)
    {
        // Reduce the speed if crouching by the crouchSpeed multiplier
        move = (crouch ? move * crouchSpeed : move);

        // The Speed animator parameter is set to the absolute value of the horizontal input.
        anim.SetFloat("Speed", Mathf.Abs(move));

        // Move the character
        rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D.velocity.y);

        // If the input is moving the player right and the player is facing left...
        if(move > 0 && !facingRight)
            // ... flip the player.
            Flip();
        // Otherwise if the input is moving the player left and the player is facing right...
        else if(move < 0 && facingRight)
            // ... flip the player.
            Flip();
    }

    // If the player should jump...
    if (grounded && jump) {
        // Add a vertical force to the player.
        anim.SetBool ("Ground", false);
        rigidbody2D.AddForce (new Vector2 (0f, jumpForce));
        numberOfAirJumpsLeft = maxNumberOfAirJumps; //Reset the air jumps when the player jumps
    }
    else if (!grounded && jump && numberOfAirJumpsLeft  > 0)
    {
        rigidbody2D.AddForce (new Vector2 (0f, jumpForce));
        numberOfAirJumpsLeft--; //One less jump
    }
}


void Flip ()
{
    // Switch the way the player is labelled as facing.
    facingRight = !facingRight;

    // Multiply the player's x local scale by -1.
    Vector3 theScale = transform.localScale;
    theScale.x *= -1;
    transform.localScale = theScale;
}
void OnTriggerEnter(Collider col)
{

    if (col.tag == "Player")
    {
        //money collected

        //destroy money object
        Destroy(gameObject);
    }
}

}

最佳答案

在每个FixedUpdate之前调用Move吗？如果是这样，它将根据半径重置接地，因此如果您足够快的话，您可能会进入第二次“接地”跳跃。然后，您可以再进行一次空中跳跃。
