# IGameInputReading::GetControllerAxisState

> IGameInputReading::GetControllerAxisState

# IGameInputReading::GetControllerAxisState

Retrieve axis state information from a game controller.

## Syntax

```cpp theme={null}
uint32_t GetControllerAxisState(
    uint32_t stateArrayCount,
    float* stateArray
);
```

### Parameters

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

The expected number of state arrays to capture the axes on a game controller.
This number can be retrieved from [IGameInputReading::GetControllerAxisCount](/reference/input/gameinput/interfaces/igameinputreading/methods/igameinputreading_getcontrolleraxiscount)

*stateArray*   \_Out\_writes\_(stateArrayCount)
Type: float\*

Pointer to the arrays which contain the axis state data.

### Return value

Type: uint32\_t

Returns the number of valid buffer entries.

## Remarks

Most analog controls on a game controller (joysticks, triggers, sliders, dials, etc.) are surfaced as axes, which are floating-point values linearly normalized to the range \[0.0, 1.0]. Most digital inputs are surfaced as buttons, which are simple Boolean values. Hat switches are surfaced as switch values, and their position is represented by one of the [GameInputSwitchPosition](/reference/input/gameinput/enums/gameinputswitchposition) enumeration values.

## Requirements
