[sesshysama]

im trying to build a game of monopoly i have a problem with moving the players on board the func that calls for the playermover that has the timer continues before timer has a chance to end unless i put a message box that waits for user input....i tried thread.sleep(); but it wont work with it...

 //call for playerMover class
playerMover.movePlayer(steps, DataBase.players[currentPlayerIndexInArr], currentPlayerIndexInArr,waiting);

 public void movePlayer( int steps,Player pl, int playersIndexInArr,toWait waiting)
        {
            toWait Waiting=waiting;
            currentPlayer = pl;
            setIndex(currentPlayer.getIndex());
            setSteps(steps);//why need this?
            setCurrentPlayerIndexInArr(playersIndexInArr);//this too
            counter = 0;
            Timer timer = new Timer();
            timer.Start();
            timer.Interval = 500;
            timer2 = timer;
            timer.Tick+=new EventHandler(timer_Tick);

            
          // with this box it works like it should
            MessageBox.Show(" ");

           
        }

        private void timer_Tick(object sender, EventArgs e)
        {
    
            if (counter < steps)
            {
                if (indexInLocationsArr == DataBase.pointsArr.Length - 1)
                    indexInLocationsArr = 0;
                else
                    indexInLocationsArr++;

                board.setLocationToPlayerButton(DataBase.pointsArr[indexInLocationsArr], currentPlayerIndexInArr);
                currentPlayer.setIndex(indexInLocationsArr);

                if (indexInLocationsArr == 0)
                {
                    //getSalary function
                    MessageBox.Show(currentPlayer.getName() + " get salary 200$");
                    currentPlayer.addCash(DataBase.salary);
                }
                counter++;


            }
            timer2.Stop();
               
               
        }
