防弹衣掉落插件无效果，请有经验的帮忙帮忙，谢谢。

版本是AMXX1.76C，加载防弹衣掉落插件之后还是没有任何效果，请问是不是缺少什么MDL或SPR才这样，可这段代码里面好像没有特别的MDL和SPR之处啊，谢谢了。源码：

                             AMX Pick Ammo
         
  Version: 0.1
  Author: KRoTaL
   
  0.1     Release
  
If you are out of ammo, instead of having to pick up another gun off the ground, pick up its ammo
just by walking over it.

  Cvar:
pickammo_limit 1    -     0: each time you walk over a weapon you'll get ammo
         1: only the first player who walks over the weapon gets ammo
      
  Setup (AMXX 1.1):
Install the amxx file.
Enable engine (in amxx's modules.ini)
Enable fun (in amxx's modules.ini
