Hey ! Is it possible to use a function as a parameter for methods or functions? Example: Function Test(a:Function) a.Call(); End It's possible in js and as3. Thanks so far! |

No |

So hopefully mark will implement it. I think it's an important thing |

So hopefully mark will implement it I doubt it, Mark wrote about function pointers awhile back: ...and some stuff removed, such as pointers. Yes, POINTERS! Function pointers too! http://marksibly.blogspot.com/2010/07/update.html |

That was not a good idea to remove them.... What's the reason for removing that feature? |

The reason is simple. It doesn't work on all targets. Java has no pointers at all. You have to use interfaces to use some kind of function pointers. Something like: Class ICallBack Abstract Method call:Void() Abstract End Class Then you have your other class where you want to use this call method: 'Implementation of the interface Class MyCallBack Extends ICallBack Method call:Void() 'Do something fancy here! End Method End Class 'Your function using the "function pointer" Function Test( a:ICallBack ) a.call(); End Function |

Hey Xaron, not as good as function pointers but a good alternative ;) Thanks for this hint |
