[SOLVED] is it possible to invert y axis on xbox 360 joypad?

Code:
37 possible variables: 

joy_active is "0" ["0"] indicates that a joystick is active (detected and enabled)

joy_axisforward is "1" ["1"] which joystick axis to query for forward/backward movement

joy_axiskeyevents is "0" ["0"] generate uparrow/leftarrow etc. keyevents for joystick axes, use if your joystick driver is not generating them

joy_axiskeyevents_deadzone is "0.5" ["0.5"] deadzone value for axes

joy_axispitch is "3" ["3"] which joystick axis to query for looking up/down

joy_axisside is "0" ["0"] which joystick axis to query for right/left movement

joy_axisup is "-1" ["-1"] which joystick axis to query for up/down movement

joy_axisyaw is "2" ["2"] which joystick axis to query for looking right/left

joy_deadzoneforward is "0.05" ["0.05"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_deadzonepitch is "0.05" ["0.05"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_deadzoneside is "0.05" ["0.05"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_deadzoneup is "0.05" ["0.05"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_deadzoneyaw is "0.05" ["0.05"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_detected is "0" ["0"] number of joysticks detected by engine

joy_enable is "0" ["0"] enables joystick support

joy_index is "0" ["0"] selects which joystick to use if you have multiple (0 uses the first controller, 1 uses the second, ...)

joy_sensitivityforward is "-1" ["-1"] movement multiplier

joy_sensitivitypitch is "0.9" ["0.9"] movement multiplier

joy_sensitivityside is "1" ["1"] movement multiplier

joy_sensitivityup is "1" ["1"] movement multiplier

joy_sensitivityyaw is "-1.8" ["-1.8"] movement multiplier

joy_x360_axisforward is "1" ["1"] which joystick axis to query for forward/backward movement

joy_x360_axispitch is "3" ["3"] which joystick axis to query for looking up/down

joy_x360_axisside is "0" ["0"] which joystick axis to query for right/left movement

joy_x360_axisup is "-1" ["-1"] which joystick axis to query for up/down movement

joy_x360_axisyaw is "2" ["2"] which joystick axis to query for looking right/left

joy_x360_deadzoneforward is "0.266" ["0.266"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_x360_deadzonepitch is "0.266" ["0.266"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_x360_deadzoneside is "0.266" ["0.266"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_x360_deadzoneup is "0.266" ["0.266"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_x360_deadzoneyaw is "0.266" ["0.266"] deadzone tolerance, suggested values are in the range 0 to 0.01

joy_x360_sensitivityforward is "1" ["1"] movement multiplier

joy_x360_sensitivitypitch is "-1" ["-1"] movement multiplier

joy_x360_sensitivityside is "1" ["1"] movement multiplier

joy_x360_sensitivityup is "1" ["1"] movement multiplier

joy_x360_sensitivityyaw is "-1" ["-1"] movement multiplier

joy_xinputavailable is "0" ["0"] indicates which devices are being reported by the Windows XInput API (first controller = 1, second = 2, third = 4, fourth = 8, added together)
