ZONE

A zone is an area in the game used to show the text of the zone being entered, to load islands, and to create locations to spawn specific vehicles and pedestrians. It is controlled by  files, which use the IPL format.

Structure
All the  files start with a section identifier and ends with the keyword "end", both in a single line.

Example: zone ... end

Format
The basic format for a  file for GTA3 and Vice City is: Name, Type, X1, Y1, Z1, X2, Y2, Z2, Island And for San Andreas and GTA IV: Name, Type, X1, Y1, Z1, X2, Y2, Z2, Island, Text
 * Name
 * Name and text of zone used from the  file


 * Type
 * Type of zone


 * X1, Y1, Z1
 * The bottom left corner of the zone


 * X2, Y2, Z2
 * The top right corner of the zone


 * Island
 * The island number


 * Text
 * Text of the zone used from the GXT file

Note that for San Andreas, the text of the zone to be displayed is also related to by an internally hardcoded table which links that zone name to its respective audio description for the police radio. This is actually the cause of a bug in the game - the zone 'SUN' (which is correctly named 'Temple' in the GXT file) gets announced as 'Sunnyside' on the police radio. This is because the internal table has two consecutive entries called 'SUN' and only the second one gets used, meaning whenever the player is in a zone named and defined as 'SUN' in this file, the police will always announce this as 'Sunnyside' since 'SUN' points to that audio entry.
