Resource:Maplimits
From Multi Theft Auto: Wiki
Map Limits is a resource that allows defining points in a .map file to border a map. A player outside the border area will lose health until he dies or returns to the game area.
Usage
Syntax:
<maplimit> <point x="" y="" /> <point x="" y="" /> <point x="" y="" /> </maplimit>
When using maplimits in ones map, at least three points must be made.
Note that the sequence of points matters. Start in the bottom left corner and work counter-clockwise.
For example, this would create a square shaped border:
<point x="0" y="0" /> <point x="1" y="0" /> <point x="1" y="1" /> <point x="0" y="1" />
While this would create two triangles:
<point x="0" y="0" /> <point x="1" y="1" /> <point x="0" y="1" /> <point x="1" y="0" />
