Delegates Where to "pick up" signature?

Development Programming & Scripting

I have a qustion be may a “dumb” qustion but goes, delegats are functions / events i can hook into.?

AActor you have the

/** Called when the actor is damaged in any way. */ 
UPROPERTY(BlueprintAssignable, Category="Game|Damage") FTakeAnyDamageSignature OnTakeAnyDamage;

Concept is somewhat new to me .
Are they for hooking functions so i can “Pick up” a event on one actor from the second?
The documentation is somewhat confusing regarding this and the wiki is a bit over simplefied.

You declare them as so.

DECLARE_DYNAMIC_MULTICAST_DELEGATE_FourParams( FTakeAnyDamageSignature, float, Damage, const class UDamageType*, DamageType, class AController*, InstigatedBy, class AActor*, DamageCauser );

And add them as so OnActorBeginOverlap.AddDynamic(objectPtr, &Class::FuFunc);
And now when ever the FuFunc is called the event will trigger?
But I dont understand what happens where do i pick up the signature?

For refrence am using

Delegates and Lamba Functions in Unreal Engine | Unreal Engine 5.1 Documentation UFunctions in Unreal Engine | Unreal Engine 5.1 Documentation

Am sure its not that hard once you manage to understand whats happening under the hood.
Thanks in advanced.

Yes, though they’re not limited to actors.

And add them as so OnActorBeginOverlap.AddDynamic(objectPtr, &Class::FuFunc); And now when ever the FuFunc is called the event will trigger?

You’ve got that backwards, whenever OnActorBeginOverlap is executed objectPtr->FuFunc() will be called with the parameters you passed to OnActorBeginOverlap.Execute() or OnActorBeginOverlap.ExecuteIfBound(). If you call objectPtr->FuFunc() directly it will have no effect whatsoever on the delegate.

But I dont understand what happens where do i pick up the signature?

I don’t understand what you mean, the signature of the delegate must match the signature of the function you hook up to the delegate.
