Closing Ring

[ThisIsReal]

Hey everyone, i need help to create a Script where a "Wall" will Close on a Random Position around the MTA Map, i  already got a snipped but i dont know how to implement it to work right.

 

local playzone_dummy = createElement("Object","playzone");
local playzone_timers = {};
local playzone_timers2 = {};

local startingzones = {
	{568,2021},
	{1954,1768},
	{1264,-423},
	{1296,-1159},
	{2086,-1507},
	{-752,-1089},
	{-1170,-1685},
	{-1956,-371},
	{-2193,632},
};

local warmuptime = 60*1000;

local circles = {
	--[1] = {radius,traveltime/staytime,percentdamage(0-1)};
	[1] = {2135,180*1000,0.04};
	[2] = {1240,120*1000,0.06};
	[3] = {740,60*1000,0.08};

	[5] = {175,20*1000,0.30};
	[6] = {90,10*1000,0.50};
	[7] = {50,5*1000,0.70};
	[8] = {0,60*1000,0.90};
};
