Detecting when the other player presses a button

Questions & Answers

I am making a 2 player multiplayer game and I need to detect when the other player presses a button, and when he presses the button it needs to change my current position, however it doesn’t work and i can’t figure why.

Here is the script i wrote:

public class Change : NetworkBehaviour {

    public GameObject player; // reference to the other player


	[SyncVar(hook="Activate")] bool activate=false;


    void Start()
    {
        if(!isLocalPlayer)
        {
            //Destroy(this);
            return;
        }

         if (this.name == "Red(Clone)")
        {
            player = GameObject.Find("Green(Clone)");
        }
        else
        {
            player = GameObject.Find("Red(Clone)");
        }

    }

	[RPC]
	void Activate(bool act)
	{
		activate = act;
	}


    void FixedUpdate()
    {
      
       	if(Input.GetKey(KeyCode.E))
        {
			player.GetComponent<Change> ().activate = true;
			player.transform.position = new Vector3 (20f, 20f);
	} 
        else
        {
			player.GetComponent<Change> ().activate = false;
         }
			
       
    }

The player seems to receive the button press only when it is received from the client, however the position is not updated. I would appreciate any help. Thanks

It looks like you’re trying to change a syncvar on a client. You should be changing them on the server, which then automatically propagate to any clients. You’ll probably want to call a Command after your GetKey is true, and update activate on the server in that command.

I don’t really see the point of your Activate hook either.
