XInputSetState

XInputSetState is a function within Microsoft's XInput API, a set of functions used to control game controllers on Windows. Specifically, XInputSetState allows an application to set the vibration and force feedback state of a connected gamepad. The function takes two arguments: a device identifier representing the controller, and a pointer to an XINPUT_VIBRATION structure. This structure contains two members, `leftMotorSpeed` and `rightMotorSpeed`, which are values between 0 and 65535. Setting these values controls the intensity of the vibration in the corresponding motors of the gamepad, allowing developers to create immersive gameplay experiences through tactile feedback. For instance, a rumble effect during an in-game explosion could be achieved by calling XInputSetState with appropriate motor speed values. The function is a key component for developers aiming to integrate advanced controller features into their Windows games and applications.
