SKNode = <parent failed to evaluate: variable not available> The code: func didBegin(_ contact: SKPhysicsContact) { let body1 = contact. So give the wall a restitution of 1 and a friction of 0 for an elastic collision. We are going to use SpriteKit’s physics engine to move our spaceship and detect collisions between spaceship and missile. A node that applies physics effects to nearby nodes. 0. But no collision detection is found. I'm using this method for masks: enum CollisionTypes: UInt32 { case holder = 1 case chef = 2 case powerups = 4 case ingredients = 8 case utensils = 16 case floor = 32 case bag = 64 case table = 128. Then it determines whether collisions or contacts occurred. SpriteKit comes with a physics engine built-in, which helps simulate realistic movements and collision detection. You can found more information about this property here, chapter "Working with Collisions and Contacts". In that case, it sounds like the projectile is being removed twice but it's not there for the second time. I'm using Xcode 8 Beta 3 (because I couldn't use Xcode 7 on MacOS Sierra) so its using the new Swift 3.

When I apply a huge impulse on the bouncing ball to have it fall on ground fast, sometimes it may pass through the ground (very thin, height=2). A polygon (mine at least) would have gaps between collision detection as it's moving, hence if I toggled the BOOL at the first contact, I'd then need to untoggle it as it ends the final contact which I can't think of a way to do. spritekit physics collision not be detected. SpriteKit Collision Detection Not Working Properly. When I detect collision with a sprite, I want it (fuelSprite) to move to a new randomly generated position.
