swift - Resetting and changing speed on SKActions -

-

is there way change velocity/speed of skaction , reset skaction?

let wait = skaction.waitforduration(5.0)  let moveright = skaction.movebyx(300, y:0, duration: 1.0)  let sequence = skaction.sequence([wait, moveright])  let endlessaction = skaction.repeatactionforever(sequence)  node.runaction(endlessaction)

this code works things change how fast skspritenode moves right @ moment it quite slow , make skspritenode return orignal position rather keep on moving right forever?

thank you

since velocity = distance / time, decreasing duration increase speed the sprite move across screen.

regarding second point, considering how skaction.movebyx(300, y:0, duration: 1.0) moves node right; skaction.movebyx(-300, y:0, duration: 1.0) must therefore move node left, original position.

hope helps.
