Why is Spaceship vibrating as it moves ?
I'm trying to move ship but it's not moving smoothly. The ship is vibrating as it moves.
void MoveShip()
{
float yPos = Input.GetAxis("Vertical") * Time.deltaTime * movementSpeed + transform.position.y;
float zPos = Input.GetAxis("Horizontal") * Time.deltaTime * movementSpeed + transform.position.z;
transform.position = new Vector3(transform.position.x, yPos, zPos);
if (movementSpeed <= 15)
{
movementSpeed = 15;
}
}

Are you moving the ship in update method? If so try moving it to fixed update.
It worked. Really thanks ! But can you explain why did it work ? What is the logic behind it ? And Should I always use FixedUpdate instead update ?
Fixed Update happens in fixed intervals while Update happens once per frame. Framerate can vary and cause unexpected results and is often the cause of skipping in movement.
In short: FixedUpdate() is called at even periods, while Update() depends on frame-rate.
Update()
- Called every frame
Used for regular updates such as :
Moving non-physics objects
Simple timers
Receiving input (aka keypress etc)
Update interval call times will vary, ie non-uniformly spaced
FixedUpdate()
- Called every physics step - FixedUpdate() intervals are consistent, ie uniformly spaced - Used for regular updates such as adjusting physic (eg. RigidBody) objects
