Sample text

We also set the tileSize value here, based on an even spacing of the tiles, along with the extra pad space we will be using between the tiles. Because we need square tiles, there is also the additional check to force the tiles to be square if the source images are not. This will distort the images, but it won't disrupt the game mechanics. Additionally, the boardOffsetX and boardOffsetY variables simply ensure the board will be nicely centered in the available board space. The flow of the game We will need several arrays in the game to help track the tiles.

If we skipped the delay, the checkForMatch method would cause this mutation (and crash) because it can remove tiles from the tilesInPlay array. Go ahead and try it yourself. Actually seeing the error messages when you know what you did wrong will help you know where to look later, when you cause a crash without knowing what you did wrong. Checking for matches Since we have done quite a bit of preparation for the rest of the mechanics of the game, it might come as a surprise that the logic to check for matching tiles is very simple.

5]; CCCallFuncND *remove = [CCCallFuncND actionWithTarget:self selector:@selector(removeMemoryTile:) data:aTile]; // Run the actions [aTile runAction:[CCSequence actions:move, scale, delay, remove, nil]]; // Play the sound effect [[SimpleAudioEngine sharedEngine] playEffect:SND_TILE_SCORE]; // Remove the tile from the tilesInPlay array [tilesInPlay removeObject:aTile]; // Add 1 to the player's score playerScore++; // Recalculate the number of lives left [self calculateLivesRemaining]; } Here we leverage the cocos2d actions heavily, using the stock actions of CCMoveTo, CCScaleTo, CCDelayTime, and CCCallFuncND.
