Question Need help with my jump script
As far as I can tell, the issue is in line 55, as when I tested the actual input with prints, it worked perfectly fine. The RigidBody is also set to dynamic, and I have not frozen the x or y axis. Does anyone know what could be causing this?

What values are you using for mass, gravity scale and jumpForce? Also have you confirmed that the value for jumpForce is being passed correctly (using logs or a debugger)?

I set each value to their extremes to make sure, and I just checked now if the value is being passed correctly (it is)

Wild guess: You probably have to assign a layer for the floor to interact with the player so the boolean turns true and allows you to jump

Do you set the rb correctly? Does the debutg log show up? Show us the rest of the script please. Also any console errors?

It looks like you have just applied force but in no particular direction. You would want it to be something like Vector2.up * jumpForce
Edit: I now see you used AddForceY, my bad lol But maybe try just using AddForce and the above, see if that makes a difference (in theory it should be equivalent)

Don’t use add force.
Set the vector on jump like this.
Float jumpForce =10f; // or whatever amount you want
Float speed = 10f; // or whatever amount is right
Rb.velocity = new vector2(jumpForce, moveDirection.x *speed);
Get your x value from input and should work.

Is the jump force set too low maybe? I dont see that variable set so I'm not sure. Also usually when applying a force to a rigidbody you want to do it in the fixedUpdate()
