swift - How to get an SKNode's zRotation relative to its scene? -


is there way sknode's zrotation relative scene rather parent? or relative other sknode?

right i'm doing this:

func rotationrelativetoscenefornode(node: sknode) -> cgfloat {     var noderotation = cgfloat(0)     var tempnode: sknode = node      while !(tempnode skscene) {         noderotation += tempnode.zrotation         tempnode = tempnode.parent!     }      return noderotation }

but i'm not sure best way it.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
