Need Help with fps movement

K.I am creating a practice fps so that i can get the basic funcions of an fps down. so im having problems with my code...when i move my gun offsets itself by a small ammount in the opposite direction that i move. here is my code.

// it contains the basic code for a GDK application

// whenever using Dark GDK you must ensure you include the header file

i need help to get any further. Also the gunflash does the exact same thing. but in opposite of the gun.
