Input.GetKeyDown(KeyCode.Mouse0)未按預期作業

我是編程新手，我遇到了這個問題，每當我使用 Input.GetKeyDown(KeyCode.Mouse0) 攻擊我的角色時，它可能會觸發 10 次中的 3 次，我嘗試更改許多變數并嘗試將代碼在不同的地方，但我找不到修復它

這是代碼：

private void Update()
{
    dirX = Input.GetAxisRaw("Horizontal") ;

    rb.velocity = new Vector2(moveSpeed * dirX , rb.velocity.y) ;

    if(Input.GetButtonDown("Jump") && (IsGrounded()))
    {
        rb.velocity = new Vector3(rb.velocity.x,jumpForce,0);
    }
    
    UpdateAnimationState();

    if(attackTime <= 0)
    {
        if(Input.GetKeyDown(KeyCode.Mouse0))
        {
            anim.SetBool("attacking", true);
            Collider2D[] enemiesToDamage = Physics2D.OverlapCircleAll( attackLocation.position, attackRange, enemies );
            for (int i = 0; i < enemiesToDamage.Length; i  )
            {
                enemiesToDamage[i].GetComponent<Enemy_health>().TakeDamage(damage);
            }
        }

        attackTime = startTimeAttack;
    }   
    else
    {
        attackTime -= Time.deltaTime;
        anim.SetBool("attacking", false);
    }

    if(attackTime <= 0)
    {
        if( Input.GetKeyDown(KeyCode.Mouse0))
        {
            if(rb.velocity.y > .01f || rb.velocity.y < -.01f)
            {
                anim.SetBool("jumpattacking", true);
                Collider2D[] damage = Physics2D.OverlapCircleAll( attackLocation.position, attackRange, enemies );
                for (int i = 0; i < damage.Length; i  )
                {
                    Destroy( damage[i].gameObject );
                }
            }
        }

        attackTime = startTimeAttack;
    }   
    else
    {
        attackTime -= Time.deltaTime;
        anim.SetBool("jumpattacking", false);
    }
}

private void OnDrawGizmosSelected()
{
    Gizmos.color = Color.red;
    Gizmos.DrawWireSphere(attackLocation.position, attackRange);
}

uj5u.com熱心網友回復：

案件應該如何jumpattacking達成？

• 要么attackTime高于0或第一種attacking情況已經開始并attackTime = startTimeAttack立即設定 -無論輸入如何！

  → 你寧愿只有在你實際攻擊時才開始冷卻！

• 然后仍然jumpattacking無法到達，因為attacking案例已經首先消耗了您的輸入并設定了計時器。

• 最后，您使用影片器 Bool 引數的方式看起來像使用 Tigger 會更好，而不是使用Tigger一次更改為某個狀態并重置觸發器。

  我不知道您的影片師是如何配置的，但可能是因為您立即在下一幀中重置 bool 引數，它會立即轉換回空閑狀態。

您可能應該做的是將兩種情況合并在一起，例如

private void Update()
{
    dirX = Input.GetAxisRaw("Horizontal") ;

    rb.velocity = new Vector2(moveSpeed * dirX , rb.velocity.y) ;

    if(Input.GetButtonDown("Jump") && IsGrounded())
    {
        rb.velocity = new Vector3(rb.velocity.x, jumpForce, 0);
    }
    
    UpdateAnimationState();

    if(attackTime <= 0)
    {
        if(Input.GetKeyDown(KeyCode.Mouse0))
        {
            // simply store this in a variable instead of implementing the same code twice
            // Use the absolute to simply check the magnitude regardless of the sign
            var isJumping = Mathf.Abs(rb.velocity.y) > 0.01f;

            // Use ternary for switching between the two bools according to the isJumping
            anim.SetBool(isJumping ? "jumpattacking" : "attacking", true);
            // disable the according other bool (?)
            // As said rather using Trigger would already solve this
            //anim.SetBool(isJumping ? "attacking" : "jumpattacking", false);
            var enemiesToDamage = Physics2D.OverlapCircleAll(attackLocation.position, attackRange, enemies);
            foreach (var enemy in enemiesToDamage)
            {
                // again decide for the resulting action according to isJumping
                if(isJumping)
                {
                    Destroy(enemy.gameObject);
                }
                else
                {
                    enemy.GetComponent<Enemy_health>().TakeDamage(damage);
                }
            }

            // You only want to do this once you actually consumed the User input
            attackTime = startTimeAttack;
        } 
    }   
    else
    {
        attackTime -= Time.deltaTime;

        // rather using Trigger parameters wold make these unnecessary
        anim.SetBool("attacking", false); 
        anim.SetBool("jumpattacking", false);
    }
}
