Hello all,
I am running into an issue where my OnBoxOverlap(function I created) is not binding to my OnComponentBeginOverlap. The signature looks correct to me and I have UFUNCTION(). Any help or suggestions would be appreciated. I get the below error message. when attempting to play inside Unreal engine.
Output Message from visual studio:
Ensure condition failed: this->IsBound() [File:C:\Program Files\Epic Games\UE_5.1\Engine\Source\Runtime\Core\Public\Delegates\DelegateSignatureImpl.inl] [Line: 1037]
