I’m using rigidbody velocity to move around and I use mouse clicks to check which direction should my player character go
I don’t know how to check when my rigidbody should make turn left or right, what should the if statement look like to choose the shortest way because if I use only right turn and then I click somewhere where left turn could do just 10 degrees to the left and it’s done it still makes right turn and does 170 degrees to the right to meet the condition to stop.
if(Input.GetMouseButtonDown(0))
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, 1000f))
{
clickPos = hit.point;
clickPos.y = 0f;
}
//playerRigidbody.velocity = Vector3.zero;
playerToMouse = clickPos - transform.position;
playerToMouse.y = 0f;
newRotation = Quaternion.LookRotation(playerToMouse);
Debug.Log(Quaternion.Angle(newRotation, playerRigidbody.rotation));
//playerRigidbody.MoveRotation(newRotation);
if( something >= something) <--- what should I put here?
{
playerRigidbody.angularVelocity = Vector3.down * ANGULARRIGID;
}
else
{
playerRigidbody.angularVelocity = Vector3.up* ANGULARRIGID;
}
}
Simply this:
if (Vector3.Dot(transform.right, playerToMouse) > 0)
You might need to swap the greater-than with a lower-than.
The dot product returns 0 when the two vectors are perpendicular to each other. If they point in the same direction it returns a positive value if it points in the opposite direction a negative value. So if it’s positive you should turn right.
