流畅的双跳Unity 2D平台游戏

Question

I'm trying to make a smooth double jump mechanic for Unity 2D, platformer game but right now the second jump is bigger if you jump right after the initial jump and I want to have it the other way around the double jump should throw you higher if you press it later like in most 2D platformer games this is my code

       private void Update()
       {
            grounded = Physics2D.OverlapArea(transform.position, GroundedEnd.position, 1 << LayerMask.NameToLayer("Ground"));
            if (grounded || !doubleJumpUsed)
            {
                playerRigidBody.AddForce(new Vector2(0, JumpPower));
            }
            if (!grounded && !doubleJumpUsed)
            {
                doubleJumpUsed = true;
            }
            UpdateJumpingAnimator();
        }

        private void UpdateJumpingAnimator()
        {
           if (grounded)
           {
               doubleJumpUsed = false;
           }
        }

Answer 1

Try this code:

playerRigidBody.AddForce(new Vector2(0, JumpPower), ForceMode2D.Impulse);

In this case it is necessary to reduce the value of the variable JumpPower

Answer 2

Honestly I'm not sure if there's a pretty way to do what you're asking. But have you tried tieing JumpPower into a timer? In other words, the longer the character is in the air the more time has elapsed, the more force is applied to the 2'nd jump when the button is pressed.
