Several factors might cause a gamepad to not work in GameMaker. These include:
Drivers and Hardware Issues: The gamepad may not have the correct drivers installed, or it might be incompatible with the system.
GameMaker Settings: If the gamepad support is not correctly configured within GameMaker's settings, it may fail to recognize the device.
Incorrect GamePad Index: GameMaker identifies gamepads with an index number. If the wrong index is used in the code, it won't detect the gamepad.
Gamepad Support in the Game: The game may have been designed without gamepad support, or the devices might not be properly mapped within the game's code.
Outdated GameMaker Version: Older versions of GameMaker might not support newer gamepads or features.
Solution - Here's How To Resolve It
To resolve the "gamemaker gamepad not working" error, try the following solutions:
Update Drivers: Ensure that the latest drivers for the gamepad are installed on your system.
Check GameMaker Settings: Verify that gamepad support is enabled in GameMaker's settings under the File > Preferences > General settings menu.
Correct GamePad Index: Make sure you're using the correct index when referring to gamepads in your code. Use functions like gamepad_is_connected(index) to check if GameMaker sees the gamepad.
Implement Gamepad Controls: If your game doesn't have gamepad controls, you'll need to code them using GameMaker's input functions such as gamepad_button_check(index, button).
Test Gamepad in a New Project: Create a simple new project that uses gamepad inputs to rule out issues with your game's code.
Use GameMaker's Device Manager: Utilize the Device Manager to simulate and debug gamepad inputs within GameMaker.
Update GameMaker: Ensure that you're running the latest version of GameMaker, as updates often include bug fixes and new device support.
If after trying these solutions the gamepad still doesn't work, consider reaching out to the community forums or checking the documentation for any known issues specific to your version of GameMaker or gamepad model.
