It works perfectly fine when the condition is only pressing the X key. The problems arose when I added to hold the W key. it works only 30% of the time.

        if (Input.GetKeyDown(KeyCode.X) && Input.GetKey(KeyCode.W)
        {
            Attackpressed = true;
        }

        if (Attackpressed)
        {
            Attackpressed = false;
            if (!isAttacking)
            {
                isAttacking = true;
            }
            if (IsGrounded())
            {
              PlayAnimation(Attackup);
            }
            Invoke("AnimationStop",0.3f);
            
            {
              PlayAnimation(Attackupaway);
            }
            

            Invoke("AnimationStop",0.3f);
        }

while holding the w key and pressing the x key, and when it is not grounded, it activates the “attackupaway” animation. I don’t want to add a transition to the animation because I have a really hard time when the logic gets complicated. Thank you
