swift - How do I call a function from another scene? -

-

my game unlocks level every-time beat level. problem im having when user beats level 1 want show button of level 2 thats in gamescene. when call function unlockleveltwo() in level1.swift file doesn't show in gamescene.swift file. doing wrong?

//gamescene.swift  func unlockleveltwo() {      let fadein = skaction.fadeinwithduration(0.5)      leveltwo.position = cgpointmake(self.size.width / 2.0, self.size.height / 2.2)     leveltwo.zposition = 20     leveltwo.setscale(0.8)     leveltwo.alpha = 0     leveltwo.runaction(fadein)     leveltwo.name = "leveltwo"     addchild(leveltwo) }   //level1.swift      if firstbody.categorybitmask == herocategory && sixthbody.categorybitmask == goldkeycategory{         //calling function gamescene unlock leveltwo button.          var gamescene = gamescene()         gamescene.unlockleveltwo()      }

this function:

if firstbody.categorybitmask == herocategory && sixthbody.categorybitmask == goldkeycategory{         //calling function gamescene unlock leveltwo button.          var gamescene = gamescene()         gamescene.unlockleveltwo()      }

is creating new gamescene object , adding childnode "leveltwo" gamescene. instead, need call unlockleveltwo() on actual gamescene presented user.

i imagine somewhere in level1.swift there reference current gamescene (the 1 user interacting with)? call function on one.

edit:

in essence, must keep reference original gamescene object somewhere in code, henceforth refer myscene. way, when in level1.swift, can reference myscene , add buttons, levels, whatever without creating new 1 did here:

var gamescene = gamescene() gamescene.unlockleveltwo()

instead, call

myscene.unlockleveltwo().

if level1 view of sort, or object gets created, in init function pass in gamescene object , set so

class level1 : (type) {     var myscene: gamescene!      init(myscene: gamescene) {         self.myscene = myscene)     } }

something that, hope helps!
