I've already seen this being talked about. I'm very very new to all this and was wondering how I'd go about making this script open a door if anyone can help me this would mean a lot to me and others.   

function init()
{
	level.shootablesNeeded = 3;
	level.shootablesCollected = 0;

	level thread shootable_1();
	level thread shootable_2();
        level thread shootable_3();
}


function shootable_1()
{
    trig_1 = GetEnt("shootable_trig_1", "targetname");
	model_1 = GetEnt("shootable_model_1", "targetname");

	trig_1 SetHintString("");
	trig_1 SetCursorHint("HINT_NOICON");

	while(1)
	{
		trig_1 waittill("trigger");

		level.shootablesCollected++;

		IPrintLn("Trigger 1 Shot"); // Not Needed

		thread shootables_done();

		break;
	}

	trig_1 Delete();
	model_1 Delete();
}

function shootable_2()
{
	trig_2 = GetEnt("shootable_trig_2", "targetname");
	model_2 = GetEnt("shootable_model_2", "targetname");

	trig_2 SetHintString("");
	trig_2 SetCursorHint("HINT_NOICON");

	while(1)
	{
		trig_2 waittill("trigger");

		level.shootablesCollected++;

		IPrintLn("Trigger 2 Shot"); // Not Needed

		thread shootables_done();

		break;
	}

	trig_2 Delete();
	model_2 Delete();
}
function shootable_3()
{
    trig_3 = GetEnt("shootable_trig_3", "targetname");
	model_3 = GetEnt("shootable_model_3", "targetname");

	trig_3 SetHintString("");
	trig_3 SetCursorHint("HINT_NOICON");

	while(1)
	{
		trig_3 waittill("trigger");

		level.shootablesCollected++;

		IPrintLn("Trigger 1 Shot"); // Not Needed

		thread shootables_done();

		break;
	}

	trig_3 Delete();
	model_3 Delete();
}



function shootables_done()
{
door_power = GetEnt("door_power", "targetname");
	while(1)
	{
self waittill(level.shootablesCollected >= level.shootablesNeeded);

if(level.shootablesCollected == level.shootablesNeeded)
{
             door_power MoveZ(-100, 5);

             wait 5;

             door_power Delete();

		        break;
		}
	}
}

Well you can store their current weapon(s) in a variable then give them a new one.

Once its over you can give them the weapons from the stored variable.

I'm not going to write a script for you but since you are making your own shooting range I would expect you at least know how to script.

This moves the "door"

door1 = GetEnt("door1", "targetname");
door1 MoveTo((-16, 80, 9), 0.5, 0.05, 0.05);

or this rotates the door.

door1 = GetEnt("door1", "targetname");
door1 RotatePitch( -5, 0.26, 0.15, 0.1 );



use a script origin to get coordinates
**MoveTo((coordinate, coordinate, coordinate), 0.5, 0.05, 0.05);
0.5=The time to move the entity in seconds
0.05=The time spent accelerating
0.05=The time spent decelerating

RotatePitch( -5, 0.26, 0.15, 0.1 );
-5=The new pitch angle in degrees
0.26=The time to rotate in seconds
0.15=The time spent accelerating in seconds
0.1=The time spent decelerating in seconds

What I mean't was if it wasn't possible with a single function just do the give_perk function for every perk at once.

Ill look right now and see if they made a function for giving them all at once.

EDIT:
It doesn't look like tryarch made a function for giving all perks.

You can just give the player every perk at the same time and it will essentially be the exact same.

If you are still having trouble with giving perks, make sure this is included in the script:

#insert scripts\zm\_zm_perks.gsh;

and for the perkname just look inside _zm_perks.gsh for all the names.(root/share/raw/scripts/zm/_zm_perks.gsh)

I think this was a mistake when HitmanVere edited it, ill fix it since function wasn't supposed to be there in the first place.

Re do the part where the script is made, at the top where the functions are threaded they are supposed to be

thread shootable_1();
thread shootable_2();

Just updated OP.

Thanks for fixing all the problems, should have tested it sooner since I wrote this from memory cause I couldn't get on steam at the time.
