I have no idea why this error is there. Using UE4.8.3 because it’s required for school.

Haven’t fixed it but I did fix some things: https://www.github.com/Greeley/TwinSticky

According to GitHub the signature of BeginOverlap should be

(AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult)

And EndOverlap should be

(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex);

I see the confusion here. The code @Greeley has is perfect but probably not for 4.8.3

I hope you managed to get it sorted.
