Control jump height and double jump

Questions & Answers

Hi, this is my code for jump and double jump, it works perfectly but cannot control the height of the jump. What I’m looking for is a maximum height the character reaches if I press the jump button long enough and variable height if I let go the jump button before the max height.

 if (Input.GetKeyDown ("space"))
         {
             if (is_Grounded)
             {
                 is_Grounded = false;
                 cir_Grounded = false;
                 cir_GroundedS = false;
                 m_Rigidbody2D.velocity = new Vector2(m_Rigidbody2D.velocity.x, 0); //need to kill velocity on y axis so I can apply a full force on the doube jump
                 m_Rigidbody2D.AddForce (new Vector2(0f, m_JumpForce));
                 doubleJump = true;
             }
             else if (doubleJump)
             {
                 m_Rigidbody2D.velocity = new Vector2(m_Rigidbody2D.velocity.x, 0);
                 m_Rigidbody2D.AddForce (new Vector2(0f, m_JumpForce));
                 doubleJump = false;
             }
         }

this is my actual code, the character has a rigidbody which is affected by gravity. Does anyone have any idea how to control the height?

Simply check for your desired height and apply a negative force … For eg.

if(m_Rigidbody2D.position.y >= YOUR DESIRED HEIGHT){
    m_Rigidbody2D.AddForce(new Vector2(0f, (m_JumpForce * -1f)));
}

I know this question has been answered, but I have a solution that manages the jump curve and gives you that less floaty feel as well as handle multi jumps.

Visit my GitHub for the code: GitHub - I-Am-Err00r/Total-Jump-Solution: The scripts for the jump solution based on the YouTube video I uploaded
