If you've skipped ahead to Chapter 8, Tips, Tools, and Ports, you'll see a recipe showing how to use the Tiled application with the TMX tilemap toolset. In this recipe, we create a 2.5D adventure game. To see our grid based pathfinding technique in action, we overload the Chapter 8, Tips, Tools, and Ports recipe entitled Creating levels using Tiled.
Execute the following code:
@interface Ch7_TileMapPathfinding : Ch8_TMXTilemap
{
NSMutableArray *grid;
float actorRadius;
}
@end
@implementation Ch7_TileMapPathfinding
-(CCLayer*) runRecipe {
//Shorter variable names
float mw = tileMap.mapSize.width;
float mh = tileMap.mapSize.height;
float tw = tileMap.tileSize.width;
float th = tileMap.tileSize.height;
/* CODE OMITTED */
//Create active and inactive nodes determined by the "Collidable" TMX layer
CCTMXLayer *collidableLayer = [tileMap...
