我使用了Here
中的教程并成功制作了类似的益智游戏（使用自定义布局和成像图块）
我现在的问题是识别用户何时完成拼图..
我和Android开发人员，但这个cocos2d对我来说很新。
我已经下载了源代码，以检查教程的编写者在用户完成拼图时找到了什么，但是他的代码没有用，我需要找到一种方法来检查每一个如果用户已经完成，则移动.. 如果它是android我不会有任何问题..
这是相关代码：
public void generateTiles(){
//We create a Node element to hold all our tiles
CCNode tilesNode = CCNode.node();
tilesNode.setTag(TILE_NODE_TAG);
addChild(tilesNode);
float scalefactor ; // a value we compute to help scale our tiles
int useableheight ;
int tileIndex = 0 ;
//We attempt to calculate the right size for the tiles given the screen size and
//space left after adding the status label at the top
int nextval ;
int[] tileNumbers = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};//{12,1,10,2,7,11,4,14,5,0,9,15,8,13,6,3}; //random but solvable sequence of numbers

基本上我只需要为我修复最后一个方法，所有其他代码仅供参考和理解最后需要的部分..
答案 0 :(得分：0)
好的，既然我已经解决了，而且我知道在这个问题上得到很好的例子和答案很难，我会在这里分享解决方案：
将此行添加为全局声明：
//Array to hold the correct order of tiles so we can compare..
private ArrayList<Tile> tilesCompleted = new ArrayList<Tile>();
并更改此方法：
public void generateTiles(){
//We create a Node element to hold all our tiles
tilesNode.setTag(TILE_NODE_TAG);
addChild(tilesNode);
float scalefactor ; // a value we compute to help scale our tiles
int useableheight ;
int tileIndex = 0 ;
//We attempt to calculate the right size for the tiles given the screen size and
//space left after adding the status label at the top
int nextval ;
//{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};//
int[] tileNumbers = {12,1,10,2,7,11,4,14,5,0,9,15,8,13,6,3}; //random but solvable sequence of numbers
//TILE_SQUARE_SIZE = (int) ((screenSize.height *generalscalefactor)/NUM_ROWS) ;
int useablewidth = (int) (screenSize.width - statusLabel.getContentSize().width*generalscalefactor ) ;
useableheight = (int) (screenSize.height - 40*generalscalefactor - statusLabel.getContentSize().height * 1.3f*generalscalefactor) ;
TILE_SQUARE_SIZE = (int) Math.min((useableheight/NUM_ROWS) , (useablewidth/NUM_COLUMNS)) ;
toppoint = (int) (useableheight - (TILE_SQUARE_SIZE / 2) + 30*generalscalefactor) ;
scalefactor = TILE_SQUARE_SIZE / 125.0f ;
topleft = (int) ((TILE_SQUARE_SIZE / 2) + 15*generalscalefactor) ;
for (int j = toppoint ; j > toppoint - (TILE_SQUARE_SIZE * NUM_ROWS); j-= TILE_SQUARE_SIZE){
for (int i = topleft ; i < (topleft - 5*generalscalefactor) + (TILE_SQUARE_SIZE * NUM_COLUMNS); i+= TILE_SQUARE_SIZE){
if (tileIndex >= (NUM_ROWS * NUM_COLUMNS)) {
break ;
}
nextval = tileNumbers[tileIndex ];
//Generate tile by it's number and it's subfolder
Tile tile = new Tile();
tile.setIndex(nextval);
tile.setSprite(CCSprite.sprite(subFolder+"/"+subFolder+"_tile_"+String.valueOf(nextval+1)+".jpg"));
tiles.add(tile);
//This is the solution
if(tileIndex > 0)
{
tile.setPositionX(i);
tile.setPositionY(j);
tile.setIndex(tileIndex);
tilesCompleted.add(tile);
}
else
tilesCompleted.add(tile);
//CCSprite tile = CCSprite.sprite(subFolder+"/"+subFolder+"_tile_"+String.valueOf(nextval+1)+".jpg");
CCNodeExt eachNode = new CCNodeExt();
eachNode.setContentSize(tile.getSprite().getContentSize());
//
//Layout Node based on calculated postion
eachNode.setPosition(i, j);
eachNode.setNodeText(nextval + "");
//Add Tile number
if(showNumbers == true)
{
CCBitmapFontAtlas tileNumber = CCBitmapFontAtlas.bitmapFontAtlas ("00", "bionic.fnt");
tileNumber.setScale(1.4f);
eachNode.setScale(scalefactor);
eachNode.addChild(tile.getSprite(),1,1);
tileNumber.setString(nextval + "");
eachNode.addChild(tileNumber,2 );
}
else
{
eachNode.setScale(scalefactor);
eachNode.addChild(tile.getSprite(),1,1);
}
if( nextval != 0){
tilesNode.addChild(eachNode,1,nextval);
}else {
emptyPosition = CGPoint.ccp(i, j);
}
//Add each Node to a HashMap to note its location
tileIndex++;
}
}
}
现在改变这个：
//This method checks if the puzzle has been correctly solved.
public boolean checkCorrect(){
//CCNode tileNodes = (CCNode) getChildByTag(TILE_NODE_TAG);
int nodeindex = 0 ;
boolean result = false;
int rowindex = 0 ;
for (int j = toppoint ; j > toppoint - (TILE_SQUARE_SIZE * NUM_ROWS); j-= TILE_SQUARE_SIZE){
if(nodeindex > 0)
{
//Log.d("y", String.valueOf(tilesNode.getChildByTag(nodeindex).getPosition().y));
//Log.d("J", String.valueOf(tilesCompleted.get(nodeindex).getPositionY()));
}
for (int i = topleft ; i < (topleft - 5*generalscalefactor) + (TILE_SQUARE_SIZE * NUM_COLUMNS); i+= TILE_SQUARE_SIZE){
if(nodeindex > 0)
{
//Log.d("x", String.valueOf(tilesNode.getChildByTag(nodeindex).getPosition().x));
//Log.d("i", String.valueOf(tilesCompleted.get(nodeindex).getPositionX()));
}
if(nodeindex>0)
{
if(tilesNode.getChildByTag(nodeindex).getPosition().x == tilesCompleted.get(nodeindex).getPositionX()
&& tilesNode.getChildByTag(nodeindex).getPosition().y == tilesCompleted.get(nodeindex).getPositionY()){
//Log.d(String.valueOf(tileNode.getChildByTag(nodeindex).getPosition().x), String.valueOf(tileNode.getChildByTag(nodeindex).getPosition().y));
//Log.d(String.valueOf(i), String.valueOf(j));
result = true ;
Log.d("Game "+String.valueOf(result), "result");
}else{
//Log.d("Game "+String.valueOf(false), "result");
return false ;
}
}
nodeindex++ ;
//Log.d("nodeindex "+String.valueOf(nodeindex), "index total");
if(nodeindex == (NUM_ROWS * NUM_COLUMNS)){
Log.d("Game "+String.valueOf(result), "result");
return result ;
}
}
}
rowindex = 0 ;
Log.d("Game "+String.valueOf(result), "result");
return result ;
}
}
好运：）
