The parallax scrolling technique adds depth to your game by moving different layers placed one above each other at different speed. Let's use it in our TilemapScene class and you'll see what I'm talking about. Perform the following steps:
Open the
TilemapScene.mfile and add the following instance variable:@implementation TilemapScene { //..skipped.. CCParallaxNode *_parallaxNode; }Then find the
addTilemapmethod and replace it with the following code:-(void)addTilemap { _tileMap = [CCTiledMap tiledMapWithFile:@"tilemap.tmx"]; _worldSize = _tileMap.contentSizeInPoints.width; //1 CCTiledMapLayer *bushes = [_tileMap layerNamed:@"Bushes"]; CCTiledMapLayer *trees = [_tileMap layerNamed:@"Trees"]; CCTiledMapLayer *ground = [_tileMap layerNamed:@"Ground"]; //2 _parallaxNode = [CCParallaxNode node]; //3 [bushes removeFromParentAndCleanup:NO]; [trees removeFromParentAndCleanup:NO]; [ground removeFromParentAndCleanup...
