Join Todd Perkins for an in-depth discussion in this video Detect collisions, part of iOS Game Development: Swift 2.0 and SpriteKit.
- So now that we've looked at how physics work…when you're building a SpriteKit scene,…let's look at how we can handle physics in our code.…Now, I mentioned briefly that you can handle…physics properties through a Sprite's physicsBody property.…So that property enables you to access…the various physics properties once you've defined…a physics definition.…For example, if we look at our Ball file,…and we select a ball, we see that it's dynamic,…allows rotation, and these are true or false,…as we can see with the check boxes,…"Friction," "Restitution," et cetera.…
These properties can all be modified in code…using the ball's property called physicsBody.…So now let's say our next goal…is to start actually detecting collisions.…So we want to shoot balls out of the cannon,…and just respond when it's bumping into other objects…because when you make a game and you build a physics engine,…you want to make sure that you know…what object is touching what other object,…and when that contact occurs.…So I'm going to save Ball, save GameScene,…
