`gamepad.isRumblePaused`	boolean	boolean	This field will return `true` if the current haptic effect on the gamepad is paused, and `false` if it isn't. It can be set to pause the effect.
`gamepad.largeMotorFrequency`	fixed point value	fixed point value	The frequency of the large motor. This is usually physically located on the left side of a gamepad.
`gamepad.smallMotorFrequency`	fixed point value	fixed point value	The frequency of the small motor. This is usually physically located on the right side of a gamepad.

Function	Parameters	Description	Returns
`gamepad:isButtonDown`	`string button`	Checks if a gamepad button is down.	boolean
`gamepad:getAxis`	`string axis, [fixed_t applyDeadzone]`	Returns the value of an axis, from `-FRACUNIT` to `FRACUNIT`. For triggers, this always returns a value from `0` to `FRACUNIT`. `applyDeadzone` is `true` by default.	fixed point value
`gamepad:getStick`	`"left" or "right", [fixed_t applyDeadzone]`	Returns the X and Y values of a stick, from `-FRACUNIT` to `FRACUNIT`. `applyDeadzone` is `true` by default.	two fixed point values
`gamepad:getTrigger`	`"left" or "right", [fixed_t applyDeadzone]`	Returns the value of a stick, from `0` to `FRACUNIT`. `applyDeadzone` is `true` by default.	fixed point value
`gamepad:getButtonName`	`string button`	Returns the name of a button. This may vary depending on the gamepad type. This is useful for displaying in e.g. menus.	string
`gamepad:getAxisName`	`string axis`	Returns the name of an axis. This may vary depending on the gamepad type. This is useful for displaying in e.g. menus.	string
`gamepad:getTriggerName`	`"left"` or `"right"`	Returns the name of a trigger. This may vary depending on the gamepad type. This is useful for displaying in e.g. menus.	string
`gamepad:rumble`	`fixed_t large_motor_frequency, [fixed_t small_motor_frequency, [tic_t duration]]`	Changes the frequency of the gamepad's motors. If the small motor's frequency is `nil`, it'll be set to the large motor's frequency. If duration is `nil` or `0`, the motors rotate forever, until they're stopped or their frequency changes.	`true` is succeeded, `false` if not
`gamepad:stopRumble`		Stops the motors on the gamepad from rotating.	string
