Question by Kilgore999 · Sep 28, 2021 at 10:11 PM · movementrigidbodyjumpdouble jump

Double jump does not work why?

Here is the code that is giving me difficulties.

         //Jump stuff
         if (Input.GetKeyDown(KeyCode.Space))
         {
             if (isGrounded)
             {
                 Jump();
             }
             else if (canDoubleJump)
             {
                 DoubleJump();
             }
         }
         Debug.Log(canDoubleJump);
 
     private void Jump()
     {
         rb.velocity = new Vector3(rb.velocity.x, 0, rb.velocity.z);
         rb.AddForce(transform.up * jumpForce, ForceMode.Impulse);
         canDoubleJump = true;
     }
 
     private void DoubleJump()
     {
         rb.velocity = new Vector3(rb.velocity.x, 0, rb.velocity.z);
         rb.AddForce(transform.up * jumpForce, ForceMode.Impulse);
         rb.AddForce(moveDirection * jumpForce / 2, ForceMode.Impulse);
         canDoubleJump = false;
     }

I checked with the debug logs and when it is in the air canDoubleJump is true. But when I try to double jump in the middle of the air, nothing happens. The player just falls down as though DoubleJump() never occurs ever.

Is there something in this code that I am missing? Because by what I can see, canDoubleJump should be true when I expected it to be true. I don't understand

looks good on first glance. Did you put a debuglog in your doublejump function to make sure that it really does not get triggered? Since you apply 2 forces you might also just cancle each other out and just not see the result.

I put a debuglog in the function. The message doesn't appear when I try to double jump, so it looks like the function is never triggered for some reason.
