# Controller Commands

> Commands for gamepad configuration and controller settings

Controller commands allow you to configure gamepad behavior, including aim assist, deadzones, and analog stick movement.

## Aim Assist

### chimera\_aim\_assist

Enable Halo's fixed aim assist for analog sticks. The PC release broke aim assist, and Chimera fixes it.

<ParamField path="enabled" type="boolean">
  true to enable aim assist, false to disable
</ParamField>

```bash theme={null}
chimera_aim_assist true
```

<Info>
  Aim assist only works with analog stick input, not mouse and keyboard.
</Info>

## Analog Input Configuration

### chimera\_deadzones

Set deadzones for analog stick input to prevent drift and unwanted movement.

<ParamField path="value" type="number">
  Deadzone amount (0.0 to 1.0)
</ParamField>

```bash theme={null}
chimera_deadzones 0.15    # 15% deadzone (recommended starting point)
chimera_deadzones 0.25    # Larger deadzone for worn controllers
```

<Tip>
  Start with a value around 0.15 and adjust based on your controller's condition. Increase if you experience drift, decrease if the controller feels unresponsive.
</Tip>

### chimera\_diagonals

Set diagonal sensitivity for analog stick movement. This compensates for Halo converting analog input to digital movement (the netcode doesn't support analog movement).

<ParamField path="value" type="number">
  Diagonal sensitivity (0.0 to 1.0)
</ParamField>

```bash theme={null}
chimera_diagonals 0.75    # Recommended value
chimera_diagonals 0.85    # More sensitive diagonals
```

<Info>
  A value of 0.75 provides good diagonal movement while maintaining accuracy.
</Info>

## Auto-centering

### chimera\_block\_auto\_center

Disable automatic view centering in vehicles.

<ParamField path="enabled" type="boolean">
  true to disable auto-centering, false to enable it
</ParamField>

```bash theme={null}
chimera_block_auto_center true
```

<Note>
  Chimera fixes the frame-rate dependent auto-centering bug, so this command is primarily for user preference.
</Note>

## Mouse Settings

### chimera\_block\_mouse\_acceleration

Disable Halo's built-in mouse acceleration. Halo uses raw input but adds its own acceleration on top.

<ParamField path="enabled" type="boolean">
  true to disable acceleration, false to enable it
</ParamField>

```bash theme={null}
chimera_block_mouse_acceleration true
```

<Warning>
  This only affects Halo's internal acceleration. Your operating system's mouse settings (bypassed by raw input) are not affected unless running in Wine.
</Warning>

### chimera\_mouse\_sensitivity

Set mouse sensitivity with more granular control than Halo's built-in settings.

<ParamField path="horizontal" type="number | 'off'">
  Horizontal sensitivity multiplier, or "off" to disable
</ParamField>

<ParamField path="vertical" type="number">
  Vertical sensitivity multiplier (required if horizontal is set)
</ParamField>

```bash theme={null}
chimera_mouse_sensitivity 2 1       # Double horizontal, normal vertical
chimera_mouse_sensitivity 1.5 0.75  # Custom ratio
chimera_mouse_sensitivity off       # Use Halo's default settings
```

<Info>
  It's recommended to disable mouse acceleration when using low sensitivity values.
</Info>

#### Sensitivity Reference Table

Equivalent values for Halo's built-in sensitivity settings:

| Halo Setting | Horizontal | Vertical |
| ------------ | ---------- | -------- |
| 10           | 4.0        | 2.0      |
| 9            | 4.0        | 2.0      |
| 8            | 3.0        | 1.5      |
| 7            | 2.0        | 1.0      |
| 6            | 1.5        | 0.75     |
| 5            | 1.25       | 0.625    |
| 4            | 1.0        | 0.5      |
| 3            | 0.75       | 0.375    |
| 2            | 0.5        | 0.25     |
| 1            | 0.25       | 0.125    |

## Controller Configuration Files

For advanced controller configuration, edit the controller settings in `chimera.ini`. Chimera supports extensive gamepad customization including:

* Button remapping
* Trigger deadzones
* Stick curve adjustments
* Multiple controller profiles

See the [Controller Configuration](/configuration/chimera-ini#controller-settings) section for detailed information.

<Tip>
  Premade controller configurations are available in the [Chimera repository](https://github.com/SnowyMouse/chimera/tree/master/controller_config).
</Tip>

## Auto Uncrouching

### chimera\_auto\_uncrouch

Control whether the game automatically uncrouches when running at full speed (original Halo PC behavior).

<ParamField path="enabled" type="boolean">
  true to re-enable auto-uncrouching, false to allow crouching while running
</ParamField>

```bash theme={null}
chimera_auto_uncrouch false  # Allow crouch-running (default)
chimera_auto_uncrouch true   # Original behavior
```
