Callback functions?

[james...@gmail.com]

Is there a way to pass a function as a parameter to use as a callback function?

function onComplete(){
// does something else
}

function doSomething(callback:Function){
// do something and when it's done...
callback();
}

doSomething(onComplete);

Function references work pretty much the same as in AS3. Only in AS3 all function values are of type Function, while in haxe a function type is defined by its arguments.

So instead of onComplete:Function, you should use onComplete:Void->Void. This means that the callback function has no arguments, and does not return anything.

As alternative, you also could use signals https://github.com/markknol/flambe-guide/wiki/Signal-Event-System

Signals look fine. Thanks!
