高手来！Sprite的使用没有运行成功，好像是路径问题。
我把ai.png存在了WTK的res下、也用eclipse试过，直接放在目录下。但运行结果都是 "路径不对 "
我没有用过Sprite请大家帮帮忙，找找问题，帮我修改好。
完整代码如下：


import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;

public class TankGameCanvas extends GameCanvas implements Runnable {
// 控制方向：
private static int INDEX_OF_UP = 0;
private static int INDEX_OF_DOWN = 1;
private static int INDEX_OF_LEFT = 3;
private static int INDEX_OF_RIGHT = 2;

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

private Sprite spriteTank; // our sprite!

// Constructor and initialization
public TankGameCanvas() {
super(true);
width = getWidth();
height = getHeight();
currentX = width / 2;
currentY = height / 2;
delay = 20;
// init sprite:
try {
Image image = Image.createImage( "/ai.png "); // 注意路径
spriteTank = new Sprite(image, 16, 16); // 大小是16x16
}
catch(Exception e) { e.printStackTrace(); }
}

// Automatically start thread for game loop
public void start() {
isPlay = true;
new Thread(this).start();
}

public void stop() { isPlay = false; }

// Main Game Loop

public void run() {
Graphics g = getGraphics();
while (isPlay) {
input();
drawScreen(g);
try {
Thread.sleep(delay);
}
catch (InterruptedException ie) {}
}
}

// Method to Handle User Inputs
private void input() {
int keyStates = getKeyStates();
// Left
if ((keyStates & LEFT_PRESSED) != 0) {
currentX = Math.max(0, currentX - 1);
spriteTank.setFrame(INDEX_OF_LEFT);
}
// Right
if ((keyStates & RIGHT_PRESSED) !=0 ) {
if ( currentX + 5 < width)
currentX = Math.min(width, currentX + 1);
spriteTank.setFrame(INDEX_OF_RIGHT);
}
// Up
if ((keyStates & UP_PRESSED) != 0) {
currentY = Math.max(0, currentY - 1);
spriteTank.setFrame(INDEX_OF_UP);
}
// Down
if ((keyStates & DOWN_PRESSED) !=0) {
if ( currentY + 10 < height)
currentY = Math.min(height, currentY + 1);

spriteTank.setFrame(INDEX_OF_DOWN);
}
}
// Method to Display Graphics
private void drawScreen(Graphics g) {
g.setColor(0); // black
g.fillRect(0, 0, getWidth(), getHeight());

// 画一个Sprite非常简单：
spriteTank.setPosition(currentX, currentY);
spriteTank.paint(g);

flushGraphics();
}
}

[解决办法]
按你的代码,应该把ai.png放到java文件一个目录下.
