- Now that we've looked at how…to run action sequences in a timeline…in a SpriteKit scene, let's look at how…to apply the same principle in code.…So here I have my bucket on the screen…and I've actually named it bucket,…so you can see if you look in Attributes Inspector,…I've given it that name so I can reference it…with code.…So save the file and head on over…to gamescene.swift…where I've created a variable called bucket,…and I've instantiated it on line 27,…just like we've done before.…
So let's go to the bottom of didMoveToView…and we're going to define how this is going to work.…Remember, we need to have one action moving…to the right, one action moving to the left,…those actions need to have easing,…we need to run them into sequence,…and it needs to repeat forever,…so let's look at how that works.…So we'll let a1, short for action one,…equal SKAction, and the action's going…to be moveBy, and I'm going to use moveByX.…Now you can use that or you can use moveBy…with a CGVector.…
Remember, a CGVector is just an XY coordinate…
