[Release] Unlimited Ammo v2

[Deviler86]

Hi,

i thought that it may be useful to switch the unlimited-ammo on and off while playing.

Since the unlimited-ammo plugin from Nukem only enables unlimited-ammo on server startup, i decided to make a dynamic version of that plugin myself.

I hope Nukem is ok with that ^^.

UnlimitedAmmoV2

Usage:
!ammo <- simple as that. Just type !ammo to enable/disable unlimited ammo

Requirements:
- @Nukem's Server Addon v1.266+

Admin Support:
If you want only Admins to use this command (which would be better ^^) you have to use the Permission plugin from Pozzuh.
I didn't implement the usage of my own AdminPlugin, since nobody wants to use it ^^

Great to see development by others, opensource ftw.

Is this working for anyone but me?

[JariZ]

This works for all players on the server

hi, active when the ammo my server goes down
you can put this plugin but with 1.4.382 update addresses if not too much trouble, thanks in advance
sorry google translator

edit: this is the error resulting when attempting to activate the ammo. logs/data: EXCEPTION: 0xC0000096 @ 0x420E6D

The Server Addon v1.266 and of course this Plugin only works with the current Server version -> 1.5.387.
There was a big update for MW3 Server and since then almost all memory addresses changed.
That's why your server is crashing. Update your server and get the newest Server Addon if you want to use this Plugin. That goes for all updated plugins aswell.

I guess I am not the only one this does not work for!

I'll need more information about your setup (Server version, addon version, plugins which you are using etc.). Otherwise i can't help you.

but my server is cracked tecknogods MW3 and are still in the 1.4.382 update would do it if I could
edit: you could not pass the previous version or adresses to create the plugin
if not too much trouble
