Catching exceptions in Kotlin looks very similar to Java try { doSomething() } catch(e: MyException) { handle(e) } finally { cleanup() } You can also catch multiple exceptions try { doSomething() } catch(e: FileSystemException) { handle(e) } catch(e: Network...

IF you are using simple categories, with each physics body belonging to only one category, then this alternative form of didBeginContact may be more readable: func didBeginContact(contact: SKPhysicsContact) { let contactMask = contact.bodyA.categoryBitMask | contact.bodyB.categoryBitMask ...

Here is a simple Sprite-Kit GameScene.swift. Create a new, empty SpriteKit project and replace the GameScene.swift with this. Then build and run. Click on any of the objects on screen to give make them move. Check the logs and the comments to see which ones collide and which ones make contact. // ...

If the tables use InnoDB, MySQL automatically uses row level locking so that multiple transactions can use same table simultaneously for read and write, without making each other wait. If two transactions trying to modify the same row and both uses row level locking, one of the transactions waits f...

Cycle Sort is sorting algorithm which uses comparison sort that is theoretically optimal in terms of the total number of writes to original array, unlike any other in-place sorting algorithm. Cycle sort is unstable sorting algorithm. It is based on idea of permutation in which permutations are facto...
