Clip.

Clip.

FullClip, more specificly. Theres also playerclip which is invisible but only bullets can go through, good for patching up crannys that ppl may get stuck in. Theres also metalclip, which does the same but makes a clank sound when walking on. The other clips, ignore those.

I used ful clip but it doesnt prevent bullets. They still pass through it. Ill use ammoclip-fullclip-ammoclip
I think that will work.

There is no ammoclip. I still need something...
EDIT:Solved. Used weapon clip.
