I want my boat in my game to move only forward when you press w or up arrow key and Not backwards when you press s or down arrow key. I also want to rotate left when you press a or the left arrow key and turn right when you press d or the right arrow key.
Assuming you’re using GetAxis, and rigidbodies for movement and rotation,
You can stop going backwards by clamping the forward/backwards input (vertical) between 0, and 1. As opposed to -1, 1 it is by default;
float forwardForce = Input.GetAxis("Vertical");
forwardForce = Mathf.Clamp(forwardForce, 0f, 1f);
rb.AddForce(transform.forward * forwardForce);
For rotation, you don’t need to clamp it because it can rotate CW and CCW.
float turn = Input.GetAxis("Horizontal");
rb.AddTorque(transform.up * turn);
Keep in mind, that both of these examples are only going to move at most 1 unit or degree per frame, not counting rigidbody drag or deltaTime. SOOOoooo you’ll probably want to multiply them by some speed variable to increase or decrease them.

Thanks a lot! That really help me, but I have a couple of questions. First question is what is CW and CCW. Second, what is AddTorque? Last question, why do you need the transform.up for rotating left or right. You have been a big help and I also I want the boat to accelerate to a certain max speed and I was wondering how I could do that!

No problem
CW = Clockwise (turn to the right)
CCW = Counter-clockwise (turn to the left)
AddTorque is the rigidbody equivalent of rotating.
We use transform.up because that’s the axis we’re rotating around
To have a max speed; just check the rigidbody’s current velocity, and if it’s over the limit you want, add more force to it, but backwards.

How would you get collision to work without my boat flying and jumping around? This worked and I thank you for that!
