When the demo runs, press the left mouse button to shoot, and the gun will recoil.
The HoldGun function has a dual purpose. It holds the gun in position to the camera, and also does the recoil when fired.
Please do not link the gun to the camera, else it will not work.
You can change the gun offset to the camera by tweaking these variables.
float xOffs = 0.3; //x offset to camers (left-right)
float yOffs = -0.3; //y offset to camers (up-down)
float zOffs = 0.5; //z offset to camers (forwards - backwards)
Link your objects, as required by the script
