Binding events in C++

Development Programming & Scripting C++

Heya!

I’m trying to turn this thingy into c++:

Basically, bind events in c++…
https://docs.unrealengine.com/latest/INT/Engine/Blueprints/UserGuide/EventDispatcher/BindingAndUnbinding/index.html

I’ve been finding stuff on delegates, but I’m not sure how they work, and if they can be unbound/bound during runtime.

Thanks!

EDIT: Found the answer, look at post below

Alright, I got it working!!

First, I create a TScriptDelegate object:


TScriptDelegate <FWeakObjectPtr> EquipFinished;

I then bind the function that I want to run:


EquipFinished.BindUFunction(this, "EquipAnimationComplete");

And then add it to the event!


MyPawn->GetMesh()->GetAnimInstance()->OnMontageBlendingOut.Add(EquipFinished);

And whenever I want to remove it, I just do this:


MyPawn->GetMesh()->GetAnimInstance()->OnMontageBlendingOut.Remove(EquipFinished);

It’s GLORIOUS! xD

Hey,

glad you figured it out.

There are also some resources in the Wiki on event handling:

Event handling
Simple Global Event System

and of course the documentation page about binding delegates:
Binding delegates

Not sure what the TScriptDelegate is exactly, it’s not in the examples. I guess it’s a wrapper type for the callback function required by dynamic delegates. (I only used normal delegates until now)

How do you give value inside


  
 TScriptDelegate <FWeakObjectPtr> EquipFinished; 


?
