Sometimes you'll want to clone a node. This tutorial shows how to spawn clones in SpriteKit so that you can avoid writing more code than necessary.
- [Instructor] Let's say you're making a space shooter game,…and you want to be able to shoot lasers.…So you're going to need to spawn lasers every so often.…Now, there's not an easy way…built into SpriteKit to do that.…Let me show you what I'm talking about.…First, I want to point out in my scene that I have no gravity,…so it's set to zero x and zero y,…which is appropriate for this kind of game.…If I select my laser object,…you'll see that I have it set to a color,…it's just a color sprite,…and then I have it set for a bounding rectangle,…and then I have some settings set up.…
Now, I've set linear damping to zero,…and I want to point out what that is.…Damping is slowing down an object,…so linear damping slows down the movement over time.…So think of throwing a baseball,…and it doesn't always go at the same speed…when you throw it,…it slows down over time,…that's what linear damping aims to create.…I've turned it to zero here for a space shooter,…because the laser doesn't need to slow down over time.…
You want it to go at a constant speed.…
