After normalizing a vector, Character not as responsive.

Questions & Answers
1

Good afternoon.

I had this small bit of code which detects which way my character is moving.

var targetVelocity = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
			targetVelocity = transform.TransformDirection(targetVelocity);
		    targetVelocity *= speed;

After testing it I found that moving diagonally would speed the player up so I changed the code to this

var targetVelocity = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
			targetVelocity = transform.TransformDirection(targetVelocity);
		    targetVelocity = targetVelocity.normalized;
		    targetVelocity *= speed;

But now for some reason when I let go of the arrow key or stick moving the character there is a delay in him stopping. Does anyone know why this might be. The fulll code is below.

Vector3 targetVelocity = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
			targetVelocity = transform.TransformDirection(targetVelocity);
		    targetVelocity = targetVelocity.normalized;
		    targetVelocity *= speed;
			
			
			Vector3 velocity = rigidbody.velocity;
			Vector3 velocityChange = (targetVelocity - velocity);
			velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
			velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
			velocityChange.y = 0.0f;
			rigidbody.AddForce(velocityChange, ForceMode.VelocityChange);

Thank you!

Edit: After testing again I have found that without the normaize it takes as long to slow down but does so at a gradual pace rather than delay then dead stop.

You probably only want to normalize the vector when it’s longer than one.

Normalizing the vector forces its lenght to 1 even when it’s shorter than 1, so it prevents your velocity from slowing down as well as growing too big.
