1) I set the delegate protocol on the SKScene header:
@interface WorldScene : SKScene <SKPhysicsContactDelegate>
2) I set delegate to the physics world:
- (id) init
{
self = [super init];
if (self)
{
self.physicsWorld.gravity = CGVectorMake(0,0);
self.physicsWorld.contactDelegate = self;
self.physicsBody = [SKPhysicsBody bodyWithEdgeLoopFromRect:self.frame];
}
return self;
}
3) I set my bitmasks:
static const uint32_t playerCategory = 0x1 << 0;
static const uint32_t wallsCategory = 0x1 << 1;
static const uint32_t endCategory = 0x1 << 2;
4) I make my player:
SKSpriteNode *player = [[SKSpriteNode alloc] initWithColor:[SKColor blueColor] size:CGSizeMake(PLAYERSIZE, PLAYERSIZE)];
player.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:player.size];
player.name = @"player";
player.physicsBody.dynamic = YES;
player.physicsBody.categoryBitMask = playerCategory;
player.physicsBody.collisionBitMask = wallsCategory;
player.physicsBody.contactTestBitMask = endCategory;
5) I make my end tile:
SKSpriteNode *tile = [[SKSpriteNode alloc] initWithColor: [SKColor whiteColor] size:CGSizeMake(TILESIZE,TILESIZE)];
if ([cell isEnd]){
tile.color = [SKColor greenColor];
tile.name = @"endTile";
tile.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize: tile.size];
NSLog(@"END TILE OF SIZE %f x %f", tile.size.width, tile.size.height);
tile.physicsBody.dynamic = YES;
tile.physicsBody.affectedByGravity = NO;
tile.physicsBody.categoryBitMask = endCategory;
tile.physicsBody.collisionBitMask = 0;
tile.physicsBody.contactTestBitMask = playerCategory;
}
6) But this never gets called! :(
- (void)didBeginContact:(SKPhysicsContact *)contact
{
NSLog(@"Touched!");
[self removeAllChildren];
}
I'm making a maze game. The player currently collides with all the walls fine, but I want the game to end when it reaches the last tile. Currently, the contact event isn't being called. I don't really know what's wrong, I have my debugger output set to displaying all output (and in any case all the children should be getting removed if it reaches the event anyway).
Whyyyyyy
