Controlling something using GUI buttons

[callimuc]

Since the iPhone versions are using the GUI buttons for the moving of the player, I was wondering how you could actually move the player by pressing it. Like is there a way to make the client think, that the player pressed a key (keydown()) even when the player just pressed a GUI? And how can it be made if the mouse slides over to the other GUI, that it won´t need to get reclicked?

The only way I was thinking of making it was this:

PHP Code:

//#CLIENTSIDE
function onCreated() {

  const PLAYER_SPEED = 0.2;
  const PLAYER_NORMAL = "block.png";
  const PLAYER_PRESSED = "lightblock.png";

  new GuiBitmapButtonCtrl("PadMovement_0") {
    x = 64;
    y = screenheight - 128;
    width = height = 32;
    text = "  Up";
    normalbitmap = mouseoverbitmap = PLAYER_NORMAL;
    pressedbitmap = PLAYER_PRESSED;
  }

  new GuiBitmapButtonCtrl("PadMovement_1") {
    x = 32;
    y = screenheight - 96;
    width = height = 32;
    text = " Left";
    normalbitmap = mouseoverbitmap = PLAYER_NORMAL;
    pressedbitmap = PLAYER_PRESSED;
  }

  new GuiBitmapButtonCtrl("PadMovement_2") {
    x = 64;
    y = screenheight - 64;
    width = height = 32;
    text = "Down";
    normalbitmap = mouseoverbitmap = PLAYER_NORMAL;
    pressedbitmap = PLAYER_PRESSED;
  }

  new GuiBitmapButtonCtrl("PadMovement_3") {
    x = 96;
    y = screenheight - 96;
    width = height = 32;
    text = "Right";
    normalbitmap = mouseoverbitmap = PLAYER_NORMAL;
    pressedbitmap = PLAYER_PRESSED;
  }
}

function PadMovement_0.onAction() {
  player.dir = 0;
  player.x += vecx(player.dir) * PLAYER_SPEED;
  player.y += vecy(player.dir) * PLAYER_SPEED;
}

function PadMovement_1.onAction() {
  player.dir = 1;
  player.x += vecx(player.dir) * PLAYER_SPEED;
  player.y += vecy(player.dir) * PLAYER_SPEED;
}

function PadMovement_2.onAction() {
  player.dir = 2;
  player.x += vecx(player.dir) * PLAYER_SPEED;
  player.y += vecy(player.dir) * PLAYER_SPEED;
}

function PadMovement_3.onAction() {
  player.dir = 3;
  player.x += vecx(player.dir) * PLAYER_SPEED;
  player.y += vecy(player.dir) * PLAYER_SPEED;
}
