这是我的第一个问题，我在SO中彻底搜索以找到问题的解决方案。但我得到它。 我正在使用cocos2d-android.jar（Cococs2d而不是Cocos2d-x）在Android中开发一个演示游戏。 以下是我加载TMX文件的java代码：
public class GameLayer extends CCLayer {
private CGSize _winSize;
protected ArrayList<CCSprite> _targets;
protected ArrayList<CCSprite> _projectiles;
protected int _projectilesDestroyed;
protected CCSprite _player;
protected CCSprite _nextProjectile;
protected CCTMXTiledMap _map;
protected CCTMXLayer _background;
protected CCTMXLayer _foreground;
protected CCTMXLayer _meta;
protected CCTMXObjectGroup _objects;
protected HashMap<String, String> _spawnPoint;
protected GameLayer() {
super();
_winSize = CCDirector.sharedDirector().displaySize();
_targets = new ArrayList<CCSprite>();
_projectiles = new ArrayList<CCSprite>();
_projectilesDestroyed = 0;
// Get TMX Map and associated layers/groups
_map = CCTMXTiledMap.tiledMap("MyTiledMap.tmx"); // The app is crashing at this line
_background = _map.layerNamed("Background");
_foreground = _map.layerNamed("Foreground");
_meta = _map.layerNamed("Meta");
_meta.setVisible(false);
_objects = _map.objectGroupNamed("Objects");
if(_objects == null){
Log.e("BoxAway", "Tile map has no objects..");
}
// Add my background layer
// TODO: Position layer in the correct spot.
// addChild(_background);
addChild(_map);
_spawnPoint = _objects.objectNamed("SpawnPoint");
_player = CCSprite.sprite("player.png");
setPlayerPosition(CGPoint.ccp(100.0f, 100.0f));
addChild(_player);
setViewPointCentered(_player.getPosition());
Context context = CCDirector.sharedDirector().getActivity();
/*SoundEngine.sharedEngine().preloadEffect(context, R.raw.pew_pew_lei);
SoundEngine.sharedEngine().playSound(context,
R.raw.background_music_aac, true);*/
this.setIsTouchEnabled(true);
this.schedule("update");
}
public void setViewPointCentered(CGPoint pos) {
float x = 0.0f;
float y = 0.0f;
x = Math.max(pos.x, _winSize.width / 2);
y = Math.max(pos.y, _winSize.height / 2);
x = Math.min(x, (_map.getMapSize().width * _map.getTileSize().width)
- _winSize.width / 2);
y = Math.min(y, (_map.getMapSize().height * _map.getTileSize().height)
- _winSize.height / 2);
CGPoint actualPos = CGPoint.ccp(x, y);
CGPoint centerOfView = CGPoint.ccp(_winSize.width / 2,
_winSize.height / 2);
CGPoint viewPoint = CGPoint.ccpSub(centerOfView, actualPos);
_background.setPosition(viewPoint);
}
public static CCScene scene() {
CCScene scene = CCScene.node();
CCLayer layer = new GameLayer();
scene.addChild(layer);
return scene;
}
@Override
public boolean ccTouchesBegan(MotionEvent event) {
return true;
}
void setPlayerPosition(CGPoint position) {
_player.setPosition(position);
}
@Override
public boolean ccTouchesEnded(MotionEvent event) {
// Choose one of the touches to work with
CGPoint touchLocation = CGPoint.ccp(event.getX(), event.getY());
touchLocation = CCDirector.sharedDirector().convertToGL(touchLocation);
touchLocation = this.convertToNodeSpace(touchLocation);
CGPoint playerPosition = _player.getPosition();
CGPoint diff = CGPoint.ccpSub(touchLocation, playerPosition);
if (Math.abs(diff.x) > Math.abs(diff.y)) {
if (diff.x > 0) {
playerPosition.x += _map.getTileSize().width;
} else {
playerPosition.x -= _map.getTileSize().width;
}
} else {
if (diff.y > 0) {
playerPosition.y += _map.getTileSize().height;
} else {
playerPosition.y -= _map.getTileSize().height;
}
}
if (playerPosition.x <= (_map.getMapSize().width * _map.getTileSize().width)
&& playerPosition.y <= (_map.getMapSize().height * _map
.getTileSize().height)
&& playerPosition.y >= 0
&& playerPosition.x >= 0) {
setPlayerPosition(playerPosition);
}
setViewPointCentered(_player.getPosition());
return true;
}
public void finishShoot() {
addChild(_nextProjectile);
_projectiles.add(_nextProjectile);
}
public void update(float dt) {
ArrayList<CCSprite> projectilesToDelete = new ArrayList<CCSprite>();
for (CCSprite projectile : _projectiles) {
CGRect projectileRect = CGRect.make(projectile.getPosition().x
- (projectile.getContentSize().width / 2.0f),
projectile.getPosition().y
- (projectile.getContentSize().height / 2.0f),
projectile.getContentSize().width,
projectile.getContentSize().height);
ArrayList<CCSprite> targetsToDelete = new ArrayList<CCSprite>();
for (CCSprite target : _targets) {
CGRect targetRect = CGRect.make(target.getPosition().x
- (target.getContentSize().width),
target.getPosition().y
- (target.getContentSize().height),
target.getContentSize().width,
target.getContentSize().height);
if (CGRect.intersects(projectileRect, targetRect)) {
targetsToDelete.add(target);
}
}
for (CCSprite target : targetsToDelete) {
_targets.remove(target);
removeChild(target, true);
}
if (targetsToDelete.size() > 0) {
projectilesToDelete.add(projectile);
}
}
/*for (CCSprite projectile : projectilesToDelete) {
_projectiles.remove(projectile);

有人可以指出我正确的方向吗？ 其他显示在Android中使用cocos2d加载和移动Tiled地图的源/链接也很受欢迎。

要解决此问题，请从https://github.com/ZhouWeikuan/cocos2d.git获取最新版本的库，构建它或查找已构建的jar。
这是https://code.google.com/p/cocos2d-android-1/issues/detail?id=50解决的问题 干杯! PZ
