Creating a Bunker

I have found the folowing code to summon a bunker:

SCP(Location){
//Created By: TheUnkn0wn
Mod=spawn("script_model",Location);
Mod setModel("com_plasticcase_enemy");
Mod Solid();
Mod CloneBrushmodelToScriptmodel(level.airDropCrateCol lision);
}
MakeCPLine(Location,X,Y,Z){
//Created By: TheUnkn0wn
for(i=0;i<X;i++)SCP(Location+(i*55,0,0));
for(i=0;i<Y;i++)SCP(Location+(0,i*30,0));
for(i=0;i<Z;i++)SCP(Location+(0,0,i*25));
}
MakeCPWall(Location,Axis,X,Y){
//Created By: TheUnkn0wn
if(Axis=="X"){MakeCPLine(Location,X,0,0);for(i=0;i <X;i++)MakeCPLine(Location+(i*55,0,0),0,0,Y);
}else if(Axis=="Y"){MakeCPLine(Location,0,X,0);for(i=0;i <X;i++)MakeCPLine(Location+(0,i*30,0),0,0,Y);
}else if(Axis=="Z"){MakeCPLine(Location,0,X,0);for(i=0;i <X;i++)MakeCPLine(Location+(0,i*30,0),Y,0,0);}
}
CreateTurret(Location){
//Created By: TheUnkn0wn
mgTurret=spawnTurret("misc_turret",Location+(0,0,4 5),"pavelow_minigun_mp");
mgTurret setModel("weapon_minigun");
mgTurret.owner=self.owner;
mgTurret.team=self.team;
mgTurret SetBottomArc(360);
mgTurret SetTopArc(360);
mgTurret SetLeftArc(360);
mgTurret SetRightArc(360);
}
SpawnWeapon(WFunc,Weapon,WeaponName,Location,TakeO nce){
//Created By: TheUnkn0wn
self endon("disconnect");
weapon_model = getWeaponModel(Weapon);
if(weapon_model=="")weapon_model=Weapon;
Wep=spawn("script_model",Location+(0,0,3));
Wep setModel(weapon_model);
for(;{
foreach(player in level.players){
Radius=distance(Location,player.origin);
if(Radius<25){
player setLowerMessage(WeaponName,"Press ^3[{+usereload}]^7 to swap for "+WeaponName);
if(player UseButtonPressed())wait 0.2;
if(player UseButtonPressed()){
if(!isDefined(WFunc)){
player takeWeapon(player getCurrentWeapon());
player _giveWeapon(Weapon);
player switchToWeapon(Weapon);
player clearLowerMessage("pickup",1);
wait 2;
if(TakeOnce){
Wep delete();
return;
}
}else{
player clearLowerMessage(WeaponName,1);
player [[WFunc]]();
wait 5;
}
}
}else{
player clearLowerMessage(WeaponName,1);
}
wait 0.1;
}
wait 0.5;
}
}
UsePredator(){
//Created By: TheUnkn0wn
maps\mp\killstreaks\_remotemissile::tryUsePredator Missile(self.pers["killstreaks"][0].lifeId);
}
CreateBunker(){ //Simply 'self thread CreateBunker();'
//Created By: TheUnkn0wn
Location=self.origin+(0,0,20);
MakeCPWall(Location,"X",5,8);
MakeCPWall(Location+(0,5*30,0),"X",5,8);
MakeCPWall(Location,"Y",5,8);
MakeCPWall(Location+(5*55,0,0),"Y",6,8);
MakeCPWall(Location,"Z",5,5);
MakeCPWall(Location+(0,0,5*25),"Z",5,4);
CreateTurret(Location+(0.25*(5*55),18,35+(4*30)));
CreateTurret(Location+(0.25*(5*55),(5*25)+1,35+(4* 30)));
SCP(Location+((4*55),84,20+4));
SCP(Location+((4*55),74,30+6));
SCP(Location+((4*55),64,40+8));
SCP(Location+((4*55),54,50+10));
SCP(Location+((4*55),44,60+12));
SCP(Location+((4*55),34,70+14));
SCP(Location+((4*55),24,80+16));
SCP(Location+((4*55),14,90+18));
SCP(Location+(45,10,6*25));
SCP(Location+(45,(5*25)+15,(6*25)));
self thread SpawnWeapon(undefined,"javelin_mp","Javelin",Locat ion+(80,30,25),0);
self thread SpawnWeapon(undefined,"rpg_mp","RPG",Location+(80, 65,25),0);

self SetOrigin(Location+(100,100,35));
}
MakeBunker(){
self endon("death");
self thread CreateBunker();
}

But this is something like a template for summoning and i wanted to implement one on a map... what would i need to change to make it work with specific locations and not with the userlocation ? or how would i bind this function to actionslot1 (n) ?
