If anyone's wondering why they can't jump, the "jump" key is set to space by default. To change it to something else, here's the code. if (Input.GetKeyDown(KeyCode.UpArrow) && IsGrounded()) { rb.velocity = new Vector2(rb.velocity.x, jumpingPower); } if (Input.GetKeyUp(KeyCode.UpArrow) && rb.velocity.y > 0f) { rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f); }

@@Bigblackhawk123You definitely done something wrong then. I had the same issue until I linked all the objects. Try watching the video multiple times to understand what is actually going on rather than saying it doesn't work. :)

[@zanahtile6276]

Check if your Ground Check is actually "grounded". If you create it first, it places the object in the middle of the player, this causes it to never touch ground. And results in failing the ground check and blocking you from jumping. Move it lower on the player.@@Bigblackhawk123

Decrease the jumping power at the top of the script.

you can change the value in the script from "private float jumpingPower" to "public float jumpingPower" and this will allow you to directly adjust the power in unity rather than opening the script! :D good luck!
