sprite kit - Swift 3: class doesn't function correctly -
so i've got class named flashypaddleeffect. mention in class, gamescene, doesn't apply effect should. paddle should flashing blue , white colors, stays white. paddle should lose physics body when blue.
if need other information, don't hesitate ask.
note: there might problems code gave (because of indents, it's quite tricky make code indenting 4 spaces every line, sorry).

1) not use nstimer use skaction. can see way doing stack timer after timer, bad.
2) not have temp variable global (node in case), makes code hard read
3) not remove physics body, remove category.
func make(applyeffectto: skspritenode, ball: skspritenode) { ballnode = ball let blue = skaction.colorize(with skcolor.blue, colorblendfactor: 1.0, duration sec: 0) let white = skaction.colorize(with skcolor.white, colorblendfactor: 1.0, duration sec: 0) let wait = skaction.wait(for:0.6) let turnonphysics = skaction.run({applyeffectto.physicsbody?.categorybitmask = #######}) let turnoffphysics = skaction.run({applyeffectto.physicsbody?.categorybitmask = 0}) let seq = [blue, turnoffphysics,wait,white,turnonphysics,wait] let repeat = skaction.repeatforever(seq) applyeffectto.run(repeat, withkey:"flashing") } note: have no idea categorybitmask is, need fill in
