Tutorial by Examples: collisions



Libraries other than jQuery may also use $ as an alias. This can cause interference between those libraries and jQuery. To release $ for use with other libraries: jQuery.noConflict(); After calling this function, $ is no longer an alias for jQuery. However, you can still use the variable jQuery...
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. // ...
In Sprite-Kit, there is the concept of collisions which refers to the SK physics engine handling how physics objects interact when they collide i.e. which ones bounce off which other ones. It also has the concept of contacts, which is the mechanism by which your program gets informed when 2 physics...
For this example, we will used 4 bodies and will show only the last 8 bits of the bit masks for simplicity. The 4 bodies are 3 SKSpriteNodes, each with a physics body and a boundary: let edge = frame.insetBy(dx: 0, dy: 0) physicsBody = SKPhysicsBody(edgeLoopFrom: edge) Note that the 'ed...
