To use a gamepad with GMod on PC, you must first connect the controller to Windows and then configure it through Steam Input so the game recognizes your button presses and analog stick movements. This two-phase process works for standard USB and Bluetooth gamepads, but mobile devices are not officially supported for Garry's Mod controller play.
Connect your gamepad to your computer
For a USB connection, plug the gamepad into any available USB port on your Windows PC. Windows will automatically install the necessary drivers for most modern controllers. If the gamepad is not recognized, use the driver disk that came with it or download the latest drivers from the manufacturer's website.
For a Bluetooth connection, put your gamepad into pairing mode according to its manufacturer instructions. Some gamepads require a specific mode or sync procedure, refer to the instruction manual. Select your controller from the list. Once paired, confirm the controller shows as connected in the same Bluetooth settings screen. Open Device Manager and verify the gamepad is listed under the relevant category without a yellow warning icon.
Configure your gamepad through Steam Input
Steam will detect your connected gamepad. Check the box for your controller type (such as Xbox, PlayStation, or Generic). In GMod's settings, enable the gamepad input option.
Click "Controller Configuration" to open the visual layout editor. This screen shows a diagram of your gamepad. Click any button or analog stick on the diagram, then press the corresponding physical button or move the stick on your actual controller to map it. You can assign keyboard keys, mouse actions, or native controller inputs to each control. Adjust analog stick sensitivity and dead zones using the sliders provided in the same layout screen.
Test and adjust your controls in GMod
Launch Garry's Mod and start a single-player game or enter sandbox mode. Press every button on your gamepad and move both analog sticks to confirm each input performs the expected action. If a button does nothing or triggers the wrong function, return to Steam's controller configuration and remap that control.
Move the sensitivity slider up for faster camera or movement response, or increase the dead zone if your analog sticks drift without being touched.
Troubleshooting common gamepad issues in GMod
If your controller is not detected, first verify it appears in Windows Settings under Bluetooth & devices. Restart Steam and GMod, then check that Steam Input is enabled in Garry's Mod's Properties. Verify GMod's game files to ensure no files are corrupted. If buttons do not respond, open the Steam controller configuration and confirm each button has an action assigned. Double-input problems occur when both Steam Input and the game's native controller support are active; disable native controller support in GMod's settings or ensure only Steam Input handles the controller.
As a fallback, third-party tools like Xpadder or JoyToKey can map gamepad buttons to keyboard and mouse inputs. These programs run outside Steam and can work when Steam Input does not recognize your controller. Create a profile in the tool, assign each gamepad button to a keyboard key GMod uses, and launch GMod normally.
For a complete gamepad setup and troubleshooting resource, follow the steps above in order. Most issues are resolved by verifying the Windows connection first, then ensuring Steam Input is properly configured for Garry's Mod.
A note on mobile gamepad use
For iPhone, Apple documents pairing a game controller through Settings > Bluetooth, turning on Bluetooth, and tapping the controller name. After pairing, open Settings > General > Game Controller to customize buttons by tapping the controls you want to change. You can use Add App to make app-specific changes or Buddy Controller to combine two compatible controllers. iPhone supports Bluetooth, Lightning, or USB-C connections depending on the model and controller, and an adapter may be required for some combinations.
For Android, Google documents pairing a wireless controller by opening Settings > Connected devices > Pair new device, putting the controller into pairing mode, and selecting its name from the Bluetooth list. Android has supported game controllers since API level 9, and controller APIs are available for Android-based game development.
However, Garry's Mod has no documented mobile controller support. The official Garry's Mod pages do not provide any iPhone or Android gamepad setup steps, button-mapping screens, supported mobile devices, or version-specific limits. If you need GMod-specific controller guidance, the official sources do not cover mobile use.
Frequently Asked Questions
Can I use any USB gamepad with GMod?
Most standard USB gamepads that Windows recognizes as a controller will work through Steam Input. Unusual or very old controllers may require third-party mapping tools like Xpadder if Steam Input does not detect them.
Will my gamepad work in multiplayer GMod servers?
Yes, once configured through Steam Input, your gamepad works in both single-player and multiplayer sessions. The controller sends keyboard and mouse inputs or native controller actions that the server accepts like any other input method.
Why does my analog stick feel too sensitive in GMod?
Open the Steam controller configuration while GMod is running and reduce the analog stick sensitivity slider. You can also increase the dead zone to prevent small stick movements from registering if the stick drifts.
Do I need to reconfigure my gamepad every time I launch GMod?
No. Steam saves your controller configuration for Garry's Mod once you apply it. The same layout loads automatically each time you start the game, unless you change it manually or reset Steam Input settings.
Can I use a PlayStation or Nintendo Switch controller with GMod?
Yes. Steam Input supports PlayStation, Switch Pro, and many third-party controllers. In Steam's General Controller Settings, check the box for your controller type, then configure it for GMod the same way as any other gamepad. Use a comfortable grip style to avoid strain during long sessions.
