Constraint which applies force to move two attachments together, or to move one attachment to a goal position.

## Properties

### Mode

```luau
AlignPosition.Mode: Enum.PositionAlignmentMode = Enum.PositionAlignmentMode.TwoAttachment
```

- Tags: Read capabilities: Physics, Simulation access

Whether the constraint uses one or two attachments in calculating its goal.

### ApplyAtCenterOfMass

```luau
AlignPosition.ApplyAtCenterOfMass: boolean = false
```

- Tags: Read capabilities: Physics, Simulation access

Whether force is applied to the parent of [`Attachment0`](https://rapi.sleaze.dev/classes/Constraint.md) at that attachment's location, or at the parents' center of mass.

### Position

```luau
AlignPosition.Position: Vector3 = Vector3.zero
```

- Tags: Read capabilities: Physics, Simulation access

The position to which the constraint should move its [`Attachment0`](https://rapi.sleaze.dev/classes/Constraint.md).

### ReactionForceEnabled

```luau
AlignPosition.ReactionForceEnabled: boolean = false
```

- Tags: Read capabilities: Physics, Simulation access

Whether the constraint applies force only to [`Attachment0`](https://rapi.sleaze.dev/classes/Constraint.md), or to both attachments in equal and opposite directions.

### RigidityEnabled

```luau
AlignPosition.RigidityEnabled: boolean = false
```

- Tags: Read capabilities: Physics, Simulation access

Whether force is dependent on other properties, or if the physics solver reacts as quickly as possible to complete the alignment.

### ForceLimitMode

```luau
AlignPosition.ForceLimitMode: Enum.ForceLimitMode = Enum.ForceLimitMode.Magnitude
```

- Tags: Read capabilities: Physics, Simulation access

Determines how the constraint force will be limited. Only used if [`RigidityEnabled`](https://rapi.sleaze.dev/classes/AlignPosition.md) is `false`.

### ForceRelativeTo

```luau
AlignPosition.ForceRelativeTo: Enum.ActuatorRelativeTo = Enum.ActuatorRelativeTo.World
```

- Tags: Read capabilities: Physics, Simulation access

Determines the axes that the constraint uses to limit the force. Only applies when [`RigidityEnabled`](https://rapi.sleaze.dev/classes/AlignPosition.md) is `false` and [`AlignPosition.ForceLimitMode`](https://rapi.sleaze.dev/classes/AlignPosition.md) is `PerAxis`. .

### MaxAxesForce

```luau
AlignPosition.MaxAxesForce: Vector3 = Vector3.new(10000, 10000, 10000)
```

- Tags: Read capabilities: Physics, Simulation access

Maximum force along each axis that the constraint can apply to achieve its goal.

### MaxForce

```luau
AlignPosition.MaxForce: number = 10000
```

- Tags: Read capabilities: Physics, Simulation access

Maximum force magnitude the constraint can apply to achieve its goal.

### MaxVelocity

```luau
AlignPosition.MaxVelocity: number = INF
```

- Tags: Read capabilities: Physics, Simulation access

Maximum speed the attachments can move when converging.

### Responsiveness

```luau
AlignPosition.Responsiveness: number = 10
```

- Tags: Read capabilities: Physics, Simulation access

Controls how quickly the constraint reaches its goal. Higher values cause the attachment(s) to align more rapidly.
