如何在触摸移动时从 CCLabelTTF 精灵获取唯一字母 cocos2d

Question

我有一个 8x8 字母矩阵游戏，当我触摸到标签时，标签值重复，如何解决这个问题，字母在 8x8 矩阵中的随机位置。

-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
   UITouch *touch=[touches anyObject];
   CGPoint newlocation=[touch locationInView:[touch view]];

   newlocation=[[CCDirector sharedDirector] convertToGL:newlocation];
   for (int i=0; i<GRID_WIDTH; i++) {
      for (int j=0; j<GRID_HEIGHT; j++) {
         if (CGRectContainsPoint([grid[i][j].letter boundingBox],newlocation)) {
            CCLOG(@"letters %@",[grid[i][j].letter string]);
            [letterarray addObject:[grid[i][j].letter string]];
         }
      }
   }
}

啊...单个网格元素中的 touchMoved 更新太多了！试试这个

     if (CGRectContainsPoint([grid[i][j].letter boundingBox],newlocation)) {
        CCLOG(@"letters %@",[grid[i][j].letter string]);
        NSString *thisLetter = [grid[i][j].letter string];
        if (![letterArray containsObject:thisLetter]) {
            [letterarray addObject:thisLetter];
        } else {
            NSLog(@"*** Skipping letter, [%@] already in the array",thisLetter);
        }
     }
