The current weapon script that does not allow the player to move when shooting is very annoying and very frustrating for players who wants to enjoy the original SAMP universe, I suggest removing this script, it is useless if everyone rush uzi and run in every direction than using an eagle or others weapons.
Original weapon handling
If you mean strafing this is based on your weapon skill (/weaponskills). This is a GTA: SA feature. Giving everyone maximum weapon skill all the time defeats the purpose of the shooting range and gives players one less thing to do.
Oh yes omg,I did not pay attention, sorry for the inconvenience, everything is perfect thank you.
