// -----------------------------------------------------------------------------
// Example Filterscript for the LS Prison Walls and Gate Objects
// -------------------------------------------------------------
// By Matite in February 2015
//
//
// This script creates the new LS Prison Walls object, removes the existing
// GTASA object and creates 2 sets of opening gates.
//
// Warning...
// This script uses a total of:
// * 5 objects = 1 for the replacement walls and 4 for the replacement gates
// * 2 3D Text Labels = 1 on each set of gates
// * Enables the /lsp command to teleport the player to the eastern prison gates
