Now let's take a look at each of the methods mentioned in the previous article, first, the Updatestatelabel method:

#pragma mark Mainscene game-related helper methods//Update lead status label in the format: fast and invincible burst through the wall through the bomb remote control-(void) updatestatelabel{NSString*state = [NSStringstringwithformat:@"%@%@%@%@%@%@", _isplayerspeedup? @"Speedy":@"    ", _player. Isinvincible? @"Unbeatable":@"    ",!_isfearbomb? @"Burst":@"    ", _player. Canacrossbrick? @"Through the wall.":@"    ", _player. Canacrossbomb? @"bullet-piercing":@"    ", _ismanualexplode? @"Remote Control":@"    "]; [_hudlayer updatestatelabel:state];}

The code is good to understand, is to create a status string based on the status of the current protagonist and then display in the label, of course, the preferred method is to use the icon to display, this can be left for later expansion.

Next look at the Initnowalltiles method, the function of this method is to traverse all non-wall tile coordinates, for the subsequent method calls to prepare, play a cache data for speed purposes:

//initialization is not all tile coordinates of the wall, but also excludes (0,0), (0,1), (1,0) three tile.-(void) initnowalltiles{CgpointBADTILEPOS1 = CCP (0,0);CgpointBadTilePos2 = CCP (0,1);CgpointBADTILEPOS3 = CCP (1,0); for(intx =0; X < _tilemap. Mapsize. Width; X + +) { for(inty =0; Y < _tilemap. Mapsize. Height; y++) {CgpointTilepos = CCP (x, y);if(Cgpointequaltopoint (Tilepos, badTilePos1) | |                Cgpointequaltopoint (Tilepos, badTilePos2) | | Cgpointequaltopoint (Tilepos, BADTILEPOS3)) {Continue; }Else if(! [ SelfIswallattilecoord:tilepos]) {[_notwalltiles addobject:[nsvalue Valuewithcgpoint:tilepos]]; }}} Nsassert (_notwalltiles. Count==249, @"_notwalltiles must equ 249");}

The code iterates through all the tile in turn, adding the coordinates of the non-wall tile to the _notwalltiles array, so that we can easily use the data in the subsequent randomly generated map method. Note that 3 coordinates are removed, respectively:

(0,0), (0,1) and (1,0)

Because the game lead bomber needs to produce in (0,0), so (0,1) and (1,0) naturally can not place bricks, otherwise the protagonist itself will be "dead end", and finally with an assertion to check the number of non-wall tile is 249, this is manually calculated in advance, a total of 30x10=300 tile, Minus the 6*8=48 wall, minus 3 of the above coordinates, and finally the remaining 249 tile can be manipulated.
