# IGameInputDevice::SetForceFeedbackMotorGain

> IGameInputDevice::SetForceFeedbackMotorGain

# IGameInputDevice::SetForceFeedbackMotorGain

Applies a global attenuation factor to all loaded effects on a motor.

## Syntax

```cpp theme={null}
void SetForceFeedbackMotorGain(
    uint32_t motorIndex,
    float masterGain
);
```

### Parameters

*motorIndex*   \_In\_\
Type: uint32\_t

Index of the motor to be changed.

*masterGain*   \_In\_\
Type: float

Global attenuation factor to all loaded effects on the motor between 0.0 and 1.0.

### Return value

None.

## Remarks

This method applies a global attenuation factor to all loaded effects on the motor. The `masterGain` pointer accepts values between 0.0 and 1.0. This is used by the application's force feedback strength settings. For more information, see [Overview of GameInput](/build/core-features/common/input/overviews/input-overview).
