Pass arguments to a delayed function with Haxe

Question

Do you know if there is an easy way to pass some arguments to a function called via

haxe.Timer.delay(func, delay);

By "easy" I mean without creating any custom timer.

Answer 1

You can use bind() for this. For example, if you want to call someFunction("abc"):

haxe.Timer.delay(someFunction.bind("abc"), 1000); // 1s

Prior to Haxe 3, you could use callback:

haxe.Timer.delay(callback(someFunction,"abc"), 1000); // 1s

Answer 2

Everything can be achieved with an extra level of indirection :-)

It seems like you need a closure whose only job is to call the other function with arguments.

Something like this (untested):

haxe.Timer.delay(function () {
    func(arg1, arg2);
}, delay);

Cameron, the only problem with that is it will treat the function as a anonymous function and remove all context. Depending on your implementation this can be a problem. – Gredel

@user: You're right, but in more recent versions of HaXe I believe the closure captures the full context (this and all). – Digged

As of today, delay in in milliseconds (eg. 1000 produces a one second delay). – Biflagellate
