I always asked myself how do the house and business systems work.

It's one single house/business mapped objects, then there's a different virtual world for each house/business or how does it work?
I don't think a house/business map is created for each pickup
I'm talking about dynamic systems.
Thanks in advance

you can use streamer's CreateDynamicObject to create an objects in different virtual worlds.

Houses and bussinesses can have different interiors.

For a dynamic system,you need to make a cmd thats gonna connect the house exit to the house entrance coordinates,create a pickup at that place amd also a 3d text label.then,you gotta save them somewhere ( a database ) and load them when the server starts.

There are a lot of this type of systems on the forum ,from where you can learn a lot of things. Good luck
