*It's a script i got from Nova i believe his name was.*
*So my problem here is, the gun auto reloads, i want to make it only reload when i press "R".*
*I tried adding if(Input.GetKeyDown("r")) Both in the IEunmerator reload AND Machine gun fire under the Bulletsleft >= 0; Either, it just doesn't reload, or gives me unlimited ammo for some reason :/*
*I really don't know what to do :| Maybe it's an obvious/easy solution, but i don't know. I barely know anything about scripting. I know a little of the basics but yeah, other than that, nope :/*
*Any help would be appreciated :smile:*
*BTW I'm really sorry about the long script, but it's easier if you have a whole view of the script i suppose :)*
