ios - Can't remove tapped spriteNode using removeFromParent : Swift -


i have for-loop instantiates 5 sprites such 

for enemy in 1...5 {     negativeoncoming = skspritenode(imagenamed: "enemy3")     negativeoncoming.physicsbody = skphysicsbody(circleofradius: negativeoncoming.frame.size.width/2)     negativeoncoming.physicsbody?.dynamic = true     negativeoncoming.physicsbody?.categorybitmask = physicscategory.negativeoncoming     negativeoncoming.physicsbody?.fieldbitmask = physicscategory.negativeoncoming     negativeoncoming.physicsbody?.contacttestbitmask = physicscategory.maincenternode | physicscategory.positiveoncoming     negativeoncoming.physicsbody?.node?.name = "negativeoncoming" self.addchild(negativeoncoming)

} declared variable globally 

var negativeoncoming : skspritenode!

now want able remove sprite thats been tapped on once tapped. attempt did 

 func removenegativeoncoming(negativeoncomingr:skspritenode){     println("tapped")     childnodewithname("negativeoncoming")?.removefromparent()        }   override func touchesbegan(touches: nsset, withevent event: uievent){     var touch = touches.anyobject() uitouch     var touchposition = touch.locationinnode(self)     var enemynodeposition = negativeoncoming.childnodewithname("negativeoncoming")?.position     var enemynodeframe = negativeoncoming.frame    func removeenemynode (uitouch) -> skspritenode {         if (enemynodeframe.contains(touchposition) ) {             removenegativeoncoming(negativeoncoming)         }         return negativeoncoming     }     mainspritemovement(touch)  }

now function in fact remove sprite , not remove sprite tapped on 1 of 5 sprites @ random. question how can have sprite tapped on me removed , not , random 1 of 5. question asked , understandable. thank all

you creating 5 enemies, setting negativeoncoming each time, variable end holding reference last node created.

this isn't cause of problem, however. using childnodewithname find node remove - of enemy nodes have same name, 1 @ random.

you can use nodeatpoint determine node tapped - 

override func touchesbegan(touches: nsset, withevent event: uievent){     var touch = touches.anyobject() uitouch     var touchposition = touch.locationinnode(self)     var touchednode = self.nodeatpoint(touchposition)     if (touchednode.name == "negativeoncoming") {         touchednode.removefromparent()     }     mainspritemovement(touch)  }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
