I’ve seen some declarations in header files such as such these as in GameMode.h:
UPROPERTY() uint32 bUseSeamlessTravel : 1; UPROPERTY() uint32 bPauseable : 1; UPROPERTY() uint32 bStartPlayersAsSpectators : 1;
Notice the : 1. I noticed that the : 1 is only used for boolean values so I think its related to the number of relevant bits. Does anyone know if this is used to optimize replication? Is there documentation on this? Thanks.
