[Release] [GSC] Zombies Custom Powerup | Unlimited Ammo

Ox_

So I was playing some zombies with a friend and wanted to do something with gsc. Just to remember the good old golden days. Thought of making a custom powerup and unlimited ammo seemed like a pretty cool one.

So it'll drop on the ground randomly just like any powerup, and when someone picks it up, every player gets unlimited ammo for 30secs. Duration can be easily changed, of course.

This is not intended for Turned or Grief. I have no idea what happens if you try to use them there. Nothing good I'd assume.
Cba'd to make it work with them because who needs unlimited ammo in Turned, and who tf plays Grief.
Other than that, should be all good. Managed to even spam myself with the powerup over 2000 times in a row with no issues.

EDIT: Seems the shader I'm using for the icon wont load in all maps KMS KMS KMS KMS KMS KMS. I fucking cba trying to find one that works. Shit's fucking impossible. I can deal with a checkerboard icon in some maps.

Hope someone finds some use, or maybe figures out how to add their own custom powerups, post them down below if you do.
And if you have any ideas for improvement, or other custom powerups, or any other custom stuff, post them down below. I might make them if I find them cool.

Nice work. If you want a challenge fix origins Easter egg with 4 people plus

Never really did easter eggs with my friends, so doubt I'd want to bother.
But well, what goes wrong with it?

Ox_ crashes the server

Lol. At what point? What needs to be done to make it crash?
Keep in mind that I don't know how the easter egg is done.

Jon_Trollsten

Hmm... maybe add death machine powerup?

frosty

Ox_ Thanks for sharing, this can be really useful. I'll keep my eye out for any servers with this feature

Xerxes

Ox_ Nice share, if you change func_should_always_drop like this you should be able to control whether the perk is enabled or not from the server cfg, you probably also want to rename it at the same time.

func_should_always_drop()
{
    if(is_true(getdvarintdefault("sv_perk_unlimited_ammo",1)))
    {
	    return 1;
    }
    return 0;
}

is_true needs #include common_scripts/utility; and getdvarintdefault needs #include maps/mp/_utility;

You can do the same for the duration and replace wait 20; with wait getdvarintdefault("sv_perk_unlimited_ammo_duration",20);

Or if you don't want to do that you can also change it to maps/mp/zombies/_zm_powerups::func_should_always_drop to use the original one and make your code a bit tidier.

Mr. Android

Great thread OP Can't wait for people to make full mods for Zombies.

Mr. Android
Brings me back to Xbox 360 modding for WaW zombies.

there is something i dont like about loops with wait
just a personal thing

turn_on_unlimited_ammo()
{
	level endon("game_ended");
	self endon("disonnect");
	self endon("end_unlimited_ammo");

        self setWeaponAmmoClip(self GetCurrentWeapon(), 150); //does it one time if you pick it up

	for(;;)
	{
                self waittill ( "weapon_fired");

		//simply set the current mag to be full on a loop
		self setWeaponAmmoClip(self GetCurrentWeapon(), 150);
	}
}

I haven't ever done stuff with servers, just hosting normally games with my friends, but good info for anyone who might care.
And dunno why I didn't just use the original function, lol.

Oh yeah, that's surely better.
Not sure why I haven't been doing that. Probably just something I picked up when I was a big noob and then it became a habit.

Ox_ After some testing I've determined that in order for this mod to work you have to inject it at the lobby in Redacted. Which means as it is right now it won't work loaded as a mod on a Plutonium server. I'm guessing its both the include_powerup() and add_zombie_power() functions being ignored since the server thinks it has already loaded all powerups for the level. Is there some way to add powerups to the the level without injection at the lobby?

This is kinda weird though since adding weapons to the box works fine and its a similar methodology. Using

include_weapons()
{
	include_weapon( "beretta93r_upgraded_zm", 1 );
}
custom_add_weapons()
{
	add_zombie_weapon( "beretta93r_upgraded_zm", undefined, &"ZOMBIE_WEAPON_BERETTA93r", 1000, "", "", undefined );
}

will put the upgraded b23r into the box on any map that has the b23r in its fast file.

Uh, I have only used this via Redacted when doing testing, and then via Steam when playing with my friends.
So I can't comment on what quirks hosting it via a Plutonium server brings. Sorry.

Maybe the Plutonium devs could offer some insight?

Ox_ Excuse me, but I was wondering if there's a file as of now or in the future that contains this code for this phenomenal custom unlimited ammo power-up, and if it can or will be easily inserted into the BO2 folder. I'm not very familiar with coding, likely along with some others on this forum, so it would be of great help if you could address whether or not it will be released publicly, or if it is and I'm too stupid to understand where it is. I would very much enjoy using this power-up during games, and many others would too.

I've edited & improved it now.
It will now work on all maps (didn't work on Buried and Origins before, luckily randomly decided to test those maps and saw it doesn't work)
And also added a download to a precompiled .gcs.

Ox_ I tested your rewrite of the mod and it works on Plutonium dedicated servers now!

Don't think I really know what that means. Is there something special about that stuff? Did it not work before? Never even been on any servers.
But anyway, glad to hear it's working.

JezuzLizard

Ox_ Plutonium is a custom bo2 client that supports 8 player dedicated zombie servers on all maps. It doesn't support GSC injection and instead uses its own modloader similar to Redacted so dedicated servers can load custom GSC mods. The GSC modloader feature is relatively new so it seems to have some interesting behavior sometimes. Eg. your old code not working but your new code does for some reason that I'll look into at some point.

I recommend you try Plutonium sometime since it has a more active playerbase than steam bo2, you can actually find games for all maps usually.

Also, I used your mod as a base to add a few extra powerups in the game files as drops like, the bonus team points, perk bottle, and random weapon. So thanks for the new version again.

Last thing, is it possible for a world at war nacht der untoten style powerup display for the infinite ammo powerup? I think it would it say Infinite Ammo: 20 and tick down from 20 at the bottom of the screen.

Yeah I know what Plutonium is/does, just didn't know what quirks are related to hosting a server and loading custom gsc, thanks.
And about the old code not working, which map did you try? the old code didn't work in Buried & Origins, as described in the Original post. The delayed registering of the custom powerup pickup function fixed that.

And cool that you added some stuff, maybe post it here if you want to share. Some other people might want to use them as well. Maybe I would use it as well next time I play zombies with my friends.

And about having a countdown or whatever to indicate when the powerup ends.
It most certainly is possible, but really cba right now at least. Already spend a few hrs trying to get the native style powerup hud to work via clientfields (as is done in the original game gsc), but every time I just errored out with client field mismatch error, and I have no idea why. So I lost motivation.

The reason why I didn't at the very first go for drawing text on the screen, is because I don't remember from on top of my head how to draw 100% safe text. Been years and years since I properly did gsc (good old Xbox 360 RGH days). Would be super pissed if the game crashed due to an overflow on like round 40 or whatever.
I guess like an iprintln would be safe to use. Looks maybe quite stupid though.
If you want an iprintln solution, and don't know how to make it yourself, I can make it for you.
