void UEngine::AddOnScreenDebugMessage
(
uint64 Key,
float TimeToDisplay,
FColor DisplayColor,
const FString & DebugMessage,
bool bNewerOnTop,
const FVector2D & TextScale
)
The signature did not changed from 4.18 but the behavior did. Now it won’t work for us with key set to anything other than -1. Any FString passed with key other than -1 won’t apper on screen.
