is there a tutorial on buy-able mg42 toretts? i carn't find 1 anywhere

Do you mean auto-turrets? Or just a turret you have to pay for to use?

For auto-turrets, I think I used this tut: Adding Auto Turrets

pay for

• You have a working turret in your map now that doesn't cost anything
• You want to buy any specific turret only once
• You want at least one turret per trigger

    thread init_turrets();

        /*--------------------
	 FUNCTION CALLS - PRE _Load
	----------------------*/
	thread init_turrets();

init_turrets(){
	//Set the cost for the trigger
	cost = 250;
	turret_trigs = getentarray("turrets", "targetname");
	for(trig=0;trig < turret_trigs.size; trig++){
		turret_trigs[trig] setCursorHint("HINT_NOICON");
		turret_trigs[trig] UseTriggerRequireLookAt();
		turret_trigs[trig] SetHintString("Press &&1 to buy turret [Cost: " + cost + "]");
		turret_trigs[trig] thread Buy_Turret(cost);
	}
}
Buy_Turret(cost){
	turrets = getentarray(self.target, "targetname");
	//if you have multiple turrets activated from one trigger
	for(turret=0;turret < turrets.size; turret++){
		turrets[turret] MakeTurretUnusable(); //disable all of them
	}
	//Wait for the trigger
	self waittill("trigger", player);
	while(player.score<cost){
		player playsound("no_cha_ching");
		self waittill("trigger", player);
	}
	player playsound("cha_ching");
	player maps\_zombiemode_score::minus_to_player_score( cost );
	for (turret=0;turret < turrets.size; turret++){
		turrets[turret] MakeTurretUsable(); //enable all of them
	}
	self delete();
}

I haven't seen a tut, but with the following assumptions:

• You have a working turret in your map now that doesn't cost anything
• You want to buy any specific turret only once
• You want at least one turret per trigger

Then this should work for you:

Radiant:

Make a trigger_use and set these kvps:
targetname: turrets
target: turret1
Select the trigger and then the turret (or turrets) you want to activate and press W. Or you can just set the turret (or turrets) kvp targetname to turret1. Same difference.

For each set of triggers and turrets, if you have more than one, name the target something else, but make sure you match the target of the trigger with the targetname of the turret that the trigger activates. Always name the targetname of the trigger turrets. Unless you change the script below.

Script:

Find FUNCTION CALLS - PRE _Load in your nazi_zombie_MAPNAME.gsc and paste this under it:

    thread init_turrets();

to look something like this:

        /*--------------------
	 FUNCTION CALLS - PRE _Load
	----------------------*/
	thread init_turrets();

Go to the end of your nazi_zombie__MAPNAME.gsc and paste this code:

init_turrets(){
	//Set the cost for the trigger
	cost = 250;
	turret_trigs = getentarray("turrets", "targetname");
	for(trig=0;trig < turret_trigs.size; trig++){
		turret_trigs[trig] setCursorHint("HINT_NOICON");
		turret_trigs[trig] UseTriggerRequireLookAt();
		turret_trigs[trig] SetHintString("Press &&1 to buy turret [Cost: " + cost + "]");
		turret_trigs[trig] thread Buy_Turret(cost);
	}
}
Buy_Turret(cost){
	turrets = getentarray(self.target, "targetname");
	//if you have multiple turrets activated from one trigger
	for(turret=0;turret < turrets.size; turret++){
		turrets[turret] MakeTurretUnusable(); //disable all of them
	}
	//Wait for the trigger
	self waittill("trigger", player);
	while(player.score<cost){
		player playsound("no_cha_ching");
		self waittill("trigger", player);
	}
	player playsound("cha_ching");
	player maps\_zombiemode_score::minus_to_player_score( cost );
	for (turret=0;turret < turrets.size; turret++){
		turrets[turret] MakeTurretUsable(); //enable all of them
	}
	self delete();
}

This script is designed to handle sets that consist of one trigger and at least one turret but not limited to one turret. The cost is set to 250 by default. Change it in the init_turrets() function if you would like, or set up a zombie_cost kvp in each trigger if you want.
