the script is createing a 2 or 3 machine gun's but i can't found the functoin of createing it to manipulte and mounted on a vehicle i want the machine gun to mount in the back of bobcat i think the code is flexible and my problem is esay to solve for those how has a exp in Lua thank alot

If you think anyone will help you if you just dump 959 lines of code, you're quite mistaken. The guides for this section clearly state that you're supposed to post relevant parts of the code, not the whole code. We're not here to make changes in a script you post here, we're here to help you make those changes.

The function which creates the weapons is create_client and it is the first function in the client-side code. The code appears to take in arguments (weapon, weapon2, weapon3) which are all elements (presumably dummy elements, but I cannot tell since you didn't post the part of the code that involves triggering createRealWeapon). It is invoked by an event handler for createRealWeapon, so what you need is the server to createElement 3 weapon dummies (or whatever elements they're supposed to be), attach them to the vehicle where you want them attached, and triggerClientEvent createRealWeapon  passing along those elements.
