There are two problems here: SKShapeNode has only one designated initializer: init(). This means that we cannot get out of our initializer without calling init(). SKShapeNode has a property path declared as CGPath!. This means that we don’t want to get out of our initializer without somehow initializing the path. The combination of those two … Read more
It seems to be working now if you are using a new way to create atlas. Important thing is that Deployment target should be >= 9.0 … Select Assets.xcassets and click to + sign to create a new sprite atlas: Choose “New Sprite Atlas” option and add @2x and @3x assets : Then in a … Read more
OK – it would appear that a simple: if bomb == nil {return} is all that’s required. This should be added as follows: let bomb = contact.bodyA.categoryBitMask == category.bomb.rawValue ? contact.bodyA.node : contact.bodyB.node if bomb == nil {return} This works to prevent multiple collisions for a node that you removeFromParent in didBeginContact. If you don;t … Read more
I get the same exception on occasion. It’s been around for a while and I’ve been trying to pinpoint it for weeks. My suspicion is that it may occur due to preloading textures, either manually or triggered automatically by Sprite Kit while at the same time some other code causes textures to be loaded or … Read more
Several problems here. You’re defining categories in a way that keeps them from being easily tested. You’re testing categories in a way that doesn’t get you the unique answers you want. You’ve confused your code by trying to track up to four bodies in one contact. Any contact will always have exactly two bodies. Let’s … Read more
I also had this issue and the cause is setting the physics body before setting the sprites position. carNode.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:carNode.size]; carNode.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)); Change the above to carNode.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)); carNode.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:carNode.size]; It should work.

Yep, use enumerateChildNodesWithName:usingBlock: and pass //* as the node name. You should be able to call that on any node. It’s actually one of the examples in Apple’s docs: //* This search string matches every node in the node tree.
Using either an SKAction or the Update loop, you can create a new SKPhysicsBody with the proper scale and apply it to the object. However, by doing so, you will lose the velocity. To fix this, you can do the following: SKPhysicsBody *newBody = [SKPhysicsBody bodyWithRectangleOfSize:boxObject.size]; newBody.velocity = boxObject.physicsBody.velocity; boxObject.physicsBody = newBody;

The second answer as promised, I just figured out the issue. I recommend to always get the latest version of this code from my gitHub project incase I made changes since this answer, link is at the bottom. Step 1: Create a new swift file and paste in this code import SpriteKit /// Scroll direction … Read more
