im not 100% sure but my guess would be to install [RELEASE]Setro-Announce: Announcements system with visuals that stand out and sound! (Fixed bug) then TriggerEvent(“announce”, -1, msg) after triggering the start of the battle royale safe zone or you could use these i believe which is taken from that script
PushScaleformMovieFunctionParameterString(“~y~Announcement”)
PushScaleformMovieFunctionParameterString(announcestring)
not 100% sure tho
