ios - Why doesn't my SKAction run properly? -


so have problem skaction dosen't run properly. runs duration of 0.2 of times instant no animation of node moving position. 

array_dot[j].runaction(skaction.movetoy(premakni_do, duration: 0.2))

more code used. function move sphere nodes 1 place down if place free underneath them (idk if code works kinda :p). 152 on y max low can go.

what run through nodes match names move them array, reverse array , move them low can go. mentioned before moving of nodes works, of times (90%) animation doesn't run. not using of physics.

func premakni_pike() {     array_dot.removeall()     var preveri_pozicija: cgfloat = 0     self.enumeratechildnodeswithname("//*")         {             node, stop in             if(node.name == "blue" || node.name == "yellow" || node.name == "red" || node.name == "green")             {                 self.array_dot.append(node)             }          }     let velikost_array = array_dot.count     array_dot = array_dot.reverse()     var premakni_do: cgfloat = 0      j in 0...velikost_array-1     {         if(array_dot[j].position.y != 156)         {             premakni_do = array_dot[j].position.y             in 0...6             {                 preveri_pozicija = array_dot[j].position.y - 60                 if(preveri_pozicija < 156)                 {                     break                 }                 print(array_dot[j].name,i,preveri_pozicija,array_dot[j].position.y)                   let novi_node = self.nodeatpoint(cgpoint(x: array_dot[j].position.x, y: preveri_pozicija))                  if(array_dot[j].intersectsnode(novi_node))                 {                     array_dot[j].position.y = preveri_pozicija                     premakni_do = premakni_do - 60                     print("prazno")                 }                 else                 {                     break                 }              }             array_dot[j].runaction(skaction.movetoy(premakni_do, duration: 0.2))         }     } }

are sure runaction not working? may setting nodes position , telling move position. try removing lines 

            if(array_dot[j].intersectsnode(novi_node))             {                 array_dot[j].position.y = preveri_pozicija                 premakni_do = premakni_do - 60                 print("prazno")             }             else             {                 break             }

caching - How to check if a url path exists in the service worker cache -

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.
