Syncing Player Movement in 2D

Questions & Answers
1

Im Making a 2D space shooter game and im trying to sync player movement and rotation over the network but i cant seem to do it smoothly. and help would be appreciated.

PlayerMovement

	void Update () {
		

		if (Input.GetKey (KeyCode.A)) {
				transform.Translate (Vector2.down * speed);

		}
		if (Input.GetKey (KeyCode.D)) {
			transform.Translate (Vector2.up * speed);
		}

Rotation Script

	void Update ()
	{
		Vector2 mouse = Camera.main.ScreenToViewportPoint (Input.mousePosition);       
		Vector3 objpos = Camera.main.WorldToViewportPoint (transform.position);       
		Vector2 relobjpos = new Vector2 (objpos.x - 0.5f, objpos.y - 0.5f);            
		Vector2 relmousepos = new Vector2 (mouse.x - 0.5f, mouse.y - 0.5f) - relobjpos;
		float angle = Vector2.Angle (Vector2.up, relmousepos);    
		if (relmousepos.x > 0)
			angle = 360 - angle;
		Quaternion quat = Quaternion.identity;
		quat.eulerAngles = new Vector3 (0, 0, angle); 
		transform.rotation = quat;
	}
}

To smooth movement over network, you have to use interpolation. I believe every tutorial about movement explains it. So, try to look at this tutor or google “network interpolation unity”

Also, one thing more that doesn’t relate to network. I see you use transform.Translate . I found this to be quite important to use Time.deltaTime every time when you Translate or Rotate. It makes movement independent on frame rate. You can google “independent frame rate movement unity” to get more information about it.

So, you should use this instead:

transform.Translate (Vector2.down * speed * Time.deltaTime);
