Hello Guys

this is me agin this time i have on Xwad MG Machine Gun Problem the problem is i can't mount the machine gun on a vehicle the code

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
