Interior

An interior is an area in the game that is not part of the outside world. This is used in Vice City, San Andreas, LCS, and VCS. The interior is not seen in the outside world and has to be loaded through the IPL file or the mission script. By default, the outside world has an interior number of 0, which doesn't act as an interior.

IPL

There is a section in the IPL that defines the interior number of an object. In the INST section, the third column denotes the interior number of the object. The object can only be viewed within this interior number. Any other objects with a different interior number will not load.

For San Andreas only, you can create an access to interiors using the ENEX section of the IPL file.

Mission Script

For Vice City, you have to use the mission script to create an access to interiors. San Andreas can also use the mission script to create an access to interiors.
