Mapping/invoking key codes in a GameCanvas's main game loop.

Question

I'm trying to bind some diagonal sprite movement methods to the keypad. I already know that I have to map out the diagonals to key codes since key states only look out for key presses in the upper half of the phone (d-pad, soft buttons, etc...). Problem is, how do I invoke them in the main game loop since a key state can be encapsulated in a method and piped through the loop? What makes this even worst is a bug that my phone maker's game API (Siemens Game API for MIDP 1.0, which is their own implementation of the MIDP 2.0 Game API) has, in which if I override the keyPressed, keyReleased, or keyRepeated methods, it will always set my key states to zero, thus I can't move the sprite at all. Also, it seems that my phone's emulator automatically maps key states to 2, 4, 6, and 8, so my only concern is how do I map the diagonal methods into 1, 3, 7, and 9, as well as invoking them in the main game loop? Enclosed is the example code that I've been working on as well as the link to a thread in the Siemens (now Benq Mobile) developer's forum about the bug's discovery:
http://agathonisi.erlm.siemens.de:8080/jive3/thread.jspa?forumID=6&threadID=15784&messageID=57992#57992
the code:
import com.siemens.mp.color_game.*;
import javax.microedition.lcdui.*;
public class ExampleGameCanvas extends GameCanvas implements Runnable {
private boolean isPlay; // Game Loop runs when isPlay is true
private long delay; // To give thread consistency
private int currentX, currentY; // To hold current position of the 'X'
private int width; // To hold screen width
private int height; // To hold screen height
// Sprites to be used
private GreenThing playerSprite;
private Sprite backgroundSprite;
// Layer Manager
private LayerManager layerManager;
// Constructor and initialization
public ExampleGameCanvas() throws Exception {
super(true);
width = getWidth();
height = getHeight();
currentX = width / 2;
currentY = height / 2;
delay = 20;
// Load Images to Sprites
Image playerImage = Image.createImage("/transparent.PNG");
playerSprite = new GreenThing (playerImage,32,32,width,height);
playerSprite.startPosition();
Image backgroundImage = Image.createImage("/background2.PNG");
backgroundSprite = new Sprite(backgroundImage);
layerManager = new LayerManager();
layerManager.append(playerSprite);
layerManager.append(backgroundSprite);
// Automatically start thread for game loop
public void start() {
isPlay = true;
Thread t = new Thread(this);
t.start();
public void stop() { isPlay = false; }
// Main Game Loop
public void run() {
Graphics g = getGraphics();
while (isPlay == true) {
input();
drawScreen(g);
try { Thread.sleep(delay); }
catch (InterruptedException ie) {}
//diagonalInput(diagonalGameAction);
// Method to Handle User Inputs
private void input() {
int keyStates = getKeyStates();
//playerSprite.setFrame(0);
// Left
if ((keyStates & LEFT_PRESSED) != 0) {
playerSprite.moveLeft();
// Right
if ((keyStates & RIGHT_PRESSED) !=0 ) {
playerSprite.moveRight();
// Up
if ((keyStates & UP_PRESSED) != 0) {
playerSprite.moveUp();
// Down
if ((keyStates & DOWN_PRESSED) !=0) {
playerSprite.moveDown();
/*private void diagonalInput(int gameAction){
//Up-left
if (gameAction==KEY_NUM1){
playerSprite.moveUpLeft();
//Up-Right
if (gameAction==KEY_NUM3){
playerSprite.moveUpRight();
//Down-Left
if (gameAction==KEY_NUM7){
playerSprite.moveDownLeft();
//Down-Right
if (gameAction==KEY_NUM9){
playerSprite.moveDownRight();
/*protected void keyPressed(int keyCode){
int diagonalGameAction = getGameAction(keyCode);
switch (diagonalGameAction)
case GameCanvas.KEY_NUM1:
if ((diagonalGameAction & KEY_NUM1) !=0)
playerSprite.moveUpLeft();
break;
case GameCanvas.KEY_NUM3:
if ((diagonalGameAction & KEY_NUM3) !=0)
playerSprite.moveUpRight();
break;
case GameCanvas.KEY_NUM7:
if ((diagonalGameAction & KEY_NUM7) !=0)
playerSprite.moveDownLeft();
break;
case GameCanvas.KEY_NUM9:
if ((diagonalGameAction & KEY_NUM9) !=0)
playerSprite.moveDownRight();
break;
repaint();
// Method to Display Graphics
private void drawScreen(Graphics g) {
//g.setColor(0x00C000);
g.setColor(0xffffff);
g.fillRect(0, 0, getWidth(), getHeight());
g.setColor(0x0000ff);
// updating player sprite position
//playerSprite.setPosition(currentX,currentY);
// display all layers
//layerManager.paint(g,0,0);
layerManager.setViewWindow(0,0,101,80);
layerManager.paint(g,0,0);
flushGraphics();
}EDIT: Also enclosed is a thread over in J2ME.org in which another user reports of the same flaw.

Answer 1

Okay...you lost me...I thought that's what I was doing?
If you mean try hitTestPoint ala this:
wally2.addEventListener(Event.ENTER_FRAME, letsSee);
function letsSee(event:Event)
          // create a for loop to test each array item hitting wally...
          for (var i:Number=0; i<iceiceArray.length; i++)
               // if you don't hit platform...
          if (wally2.hitTestPoint(iceiceArray[i].x, iceiceArray[i].y, false)) {
          wally2.y -= 5;}
                      return;
That's not working either.
