java - KeyListener for multiplayer game with keys being pressed at the same time? -

-

I am writing a two-player snake game. The arrow keys respond to a snake and the WASD keys answer the other, though I have seen in my code that if one key is pressed at the same time for each snake then only a snake turns up. I have two main listers. Which consists of an array of four keys which should answer it. 

  Class PlayerExpilerListener implies KeyListener {set of currently pressed keys set to personal finals & lt; Integer & gt; buried; Private int event []; Private color C; Private IT; Public PlayerPreviousListener (Int [] A, Color Call, Int I) {Super; Pressed = NewHashet & lt; Integer & gt; (); KeyEvent = a; C = col; This.i = i; } @ Override Press the public volume key (key E) {if pressed content (main event [0]) || pressed ears (key event [1]) || pressed ears (key event [2]) || pressed Pressed (keyEvent [3])) .ed (e.getKeyCode ()); ProccessKey (e.getKeyCode ()); } @ Override Public Wide Key Related (Key Event E) {Pressed. Remove (E. gecakecode ()); } @ Override Public Wide Type (keyEvent) {/ * is not used * Public Zero Processing that is (key) {if (canturn [i]) {int d = grid.getDirection (c); If (key == key event [0]) {if (D == 360) grid Set Direction (D-90, C); // Specifies the direction of snake with specific color and if (d = 180 = 180) grid Set Direction (D + 90, C); } And if (key == keyive [1]) {if (d == 360) grid. Set Direction (d + 90, c); Else if (d == 180) grid.setDirection (d - 90, c); } And if (key == keyive [2]) {if (d == 90) grid.setDirection (d-90, c); Else if (d == 270) grid.setDirection (d + 90, c); } And if (key == main event [3]) {if (d == 90) grid.set direct (d + 90, c); Else if (d == 270) grid.setDirection (d-90, c); } CanTurn [i] = false; }}}

This is where they are created: 

  int [] a = {KeyEvent.VK_LEFT, key event VK_RIHT, KEVENT VK_UP, key event .VK_DOWN}; Int [] B = {KeyEvent.VK_A, Key Event. VK_D, KeyEvent.VK_W, KeyEvent.VK_S}; This.addKeyListener (new playercomplier (a, Color.blue, 0)); This.addKeyListener (New PlayerKeyPressListener (B, Color.red, 1));

Is there a way for two players to make it more sensitive?

I am using parameterized select questions in conjunction with my program and it works entirely, When I try to join the table Everything I have done is a small fraction: using (MySqlCommand cmd = new MySqlCommand (paramQuery) ToSql (), Connection)) /etc/ paramQuery.ToSql () Equal: "Select TableOne ID, Tableon, Department, Tablet. One by name table, Table 2 h Yes TableOnEID = @Pharmak "* / for (Int Index = 0; Index and Lt; ParamariX Parameter (.c calculation; Index ++) Cmd.Parameters.AddWithValue (paramQuery.Parameters ().

ElementAt (index) .Value = "tableTwo.ID" * / MySqlDataReader Reader = cmd.ExecuteReader (); While (reader.Read ()) {// do stuff} } One of the tables I attempt to join is For the table, two with the same id for all. Is there something that I'm doing wrong?
