Try searching "hackingwithswift collision detection", that should get you started with dealing with the physics engine and collisions. You should use: // You should set collision bit mask to avoid collisioning. SpriteKit provides a dedicated delegate for collision detection, SKPhysicsContactDelegate, which allows to respond whenever two physics entities are in contact. It will return a BOOL indicating if the tip of the spike rests inside the ball. let playerCategory: UInt32 = 0x1 << 0 let coinCategory: UInt32 = 0x1 << 1. Detecting Collision SpriteKit Swift. For instance, if we have the following categories set up:. user4233369 user4233369. If this can be done directly in the collision detection function, that would be even better as there would be no extra frame dedicated to calculating the touch direction. I've been trying to figure this out for quite a while now -- I have a game with simple platformer physics where a player falls onto a block, which stops him from falling. 25, target: self, selector: #selector (CreateNewBullet) , userInfo: nil,.

In both cases (new game and continue from save game) the physics bodies are the same - dynamic, same size body, same contactTestBitMask, same categoryBitMask. Note that this is incorrect if you want to detect the collision between two bodies, as per the original question. By detecting collision between the invisible "sticks" I can tell wherether the object is close to the wall or not. You might want to make sure you reset your players position to be above the ground when contact with the ground is detected. I'm hoping I missed something simple.

In the didBeginContact method I have a collision between a bullet and an alien. When the player collides with the projectiles, the score changes and the projectile disappears. In order for the game to detect collisions between objects, we need to set the scene's physics world's contactDelegate property. This works, however there is a noticeable gap between where the player stops, and where the actual object/spritenode is. Modified 9 years, 7 months ago. Otherwise the player could still be in contact with the ground when [self jumping]; is called which can sometimes result in the player being "stuck".
