Strange bug, black screen and invalid input position NaN error

Questions & Answers
1

Hi, im working on puzzle game in multiplayer and works all well(about all =) ), anyway when i try my game on my computer, i launch editor and pc, mac & linux standlone .exe, all seems to be fine except when i press ‘w’ or 'a ’ or ‘s’ or ‘d’ movement key in exe for move player, then black screen in game appear immediately on editor and it show this error message:

transform.position assign attempt for ‘Player(Clone)’ is not valid. Input position is { NaN, NaN, NaN }.
UnityEngine.Transform:set_position(Vector3)
MovementUpdate:UpdateMovement(Vector3, Quaternion) (at Assets/scripts/Network Scripts/MovementUpdate.cs:72)

not change nothing if i make vice-versa(client/server - server/client), ever if i press any movement button key, black screen appear and error message is printing(black screen appear only in exe, editor works perfectly in all two case)

I try another solution, i build exactly same project in web player, and this time works both(client/server - server/client), without black screen and errors.

There is my pc info:

  • Windows 7 Home Premium Service Pack 1
  • HP Pavilion dv6 Notebook PC
  • Intel(R) Core™ i7-2630QM CPU @ 2.00GHz 2.00 GHz
  • 4,00 GB RAM
  • 64 bit
  • Kaspersky PURE

And this is the script that give me error:(only in exe, of course)

using UnityEngine;
using System.Collections;

/// <summary>
/// This script is attached to the player and it
/// ensure that every players position, rotation, and scale,
/// are kept up to date across the network
/// </summary>

public class MovementUpdate : MonoBehaviour {

    //Variables Start_________________________

    private Vector3 _lastPosition;
    private Quaternion _lastRotation;
    private Transform _myTransform;

    //Variables End_________________________

	// Use this for initialization
	void Start () {
        if (networkView.isMine)
        {
            _myTransform = transform;

            //ensure that everyone sees the player at the correct location
            //the moment they spawn
            networkView.RPC("UpdateMovement", RPCMode.OthersBuffered,
                            _myTransform.position, _myTransform.rotation);
        }

        else
        {
            enabled = false;
        }
	}
	
	// Update is called once per frame
	void Update () 
    {
	    //if the player has moved at all then fire off an RPC to update the players
        //position and rotation across the network

        if (Vector3.Distance(_myTransform.position, _lastPosition) >= 0.1f)
        {
            //Capture the player's position before the RPC is fired off and use this
            //to determine if the player has moved in the if statement above

            _lastPosition = _myTransform.position;

            networkView.RPC("UpdateMovement", RPCMode.OthersBuffered,
                            _myTransform.position, _myTransform.rotation);
        }

        if (Quaternion.Angle(_myTransform.rotation, _lastRotation) >= 1)
        {
            //Capture the player's rotation before the RPC is fired off and use this
            //to determine if the player has turned in the if statement above

            _lastRotation = _myTransform.rotation;

            networkView.RPC("UpdateMovement", RPCMode.OthersBuffered,
                            _myTransform.position, _myTransform.rotation);
        }
	}

    [RPC]
    void UpdateMovement(Vector3 newPosition, Quaternion newRotation)
    {
        //print(newPosition.ToString());
        //print(newRotation.ToString());
        transform.position = new Vector3(newPosition.x, newPosition.y, newPosition.z);

        transform.rotation = new Quaternion(newRotation.x, newRotation.y, newRotation.z, newRotation.w);
    }
}

Thanks for help, i dont know what i can i do. S:

anyone knows how to fix this problem? :frowning:

I was getting this issue in build versions of my game. Check to see if your build has a corrupted resources.assets file. If it does, fix it. The fix for mine, was that I had multiple script files with the same name in both JS and C#.
