try this
beforehand in a device placed in the game eg game_manager do this
var MyVariable:weak_map(session,creative_device_base)= map{}
game_manager := class(creative_device):
@editable YourIslandSettings : experience_settings_device = experience_settings_device{}
OnBegin():void=
if(set MyVariable[GetSession()]=YourIslandSettings){Print("DEVICE HAS BEEN SET")}
then in whatever other script
if(ADevice:=MyVariable[GetSession()]?):
AllCreativeObjects:=ADevice.FindCreativeObjectsWithTag(helper{})
Edited to replace device mentions to the islandsettings device
