Xinput Test Not Working on Tablet: Understanding Gamepad Input in Unity

When it comes to developing games for tablets or other mobile devices, understanding how gamepads work can be crucial. In this article, we'll explore the intricacies of gamepad input in Unity and provide solutions for common issues like XInput not working on a tablet.

Polling Frequency Control

One important aspect of gamepad input is polling frequency, which refers to the rate at which the device sends updates about button presses and movements. In Unity, you can control this frequency manually using the `InputSystem.pollingFrequency` property. This allows you to fine-tune your gamepad's performance and optimize it for specific devices.

Xbox and PS4 Controllers

Unity supports both Xbox and PS4 controllers, which means that developers can create games that work seamlessly with a wide range of devices. For example, the `Gamepad.current` accessor provides access to the current gamepad being used, while the `Gamepads` class allows you to retrieve information about multiple gamepads connected to the device.

Button Aliases and Enumerations

Gamepads often have both Xbox-style and PS4-style button aliases on buttons. This can make it easier for developers to create games that work with multiple devices. For example, the left and right triggers can function as buttons as well as full floating-point axes. The `GamepadButton` enumeration provides a way to access gamepad buttons using their index or name.

Face Buttons and D-Pad

The face buttons on a gamepad typically include four action buttons (X, A, B, and Y) that are usually located on the right side of the device. These buttons can be accessed using the `Gamepad` class and the `GamepadButton` enumeration. The D-pad is also an important part of many gamepads, providing up/down/left/right buttons for use like a directional pad.

Thumbsticks and Gyro

Thumbsticks are another key feature of many gamepads, allowing players to control games with precision. Some gamepads also include gyroscopes or accelerometers that can be used to track movement. These sensors can provide valuable data for developers looking to create immersive gaming experiences.

Gamepad Support in Unity

Unity provides a range of features and tools designed to make it easy to add gamepad support to your games. For example, the `InputSystem` package includes a sample demonstrating how to set up gamepad input to drive a virtual mouse cursor. This can be useful for developers looking to create games that work with multiple devices.

In this article, we've explored some of the key features and concepts related to gamepad input in Unity. Whether you're developing a game for tablets or other mobile devices, understanding how gamepads work is crucial for creating engaging and immersive gaming experiences. By using the techniques and tools described above, developers can create games that work seamlessly with a wide range of devices and provide players with a rich and rewarding experience.
