**Deprecated:** This service has been deprecated in favor of [constraints](https://create.roblox.com/docs/physics/mechanical-constraints) which should be used for surface connections instead

A service that stores joints created by surface connections.

## Methods

### ClearJoinAfterMoveJoints

```luau
JointsService:ClearJoinAfterMoveJoints()
```

- Tags: Capabilities: Physics

Will remove any 'create joints' that were made visible via the [`JointsService:ShowPermissibleJoints()`](https://rapi.sleaze.dev/classes/JointsService.md) method.

### CreateJoinAfterMoveJoints

```luau
JointsService:CreateJoinAfterMoveJoints()
```

- Tags: Capabilities: Physics

Updates all visible joints for the parts assigned by the [`JointsService:SetJoinAfterMoveTarget()`](https://rapi.sleaze.dev/classes/JointsService.md) and [`JointsService:SetJoinAfterMoveInstance()`](https://rapi.sleaze.dev/classes/JointsService.md) methods.

### SetJoinAfterMoveInstance

```luau
JointsService:SetJoinAfterMoveInstance(joinInstance: Instance)
```

- Tags: Capabilities: Physics

Sets the PVInstance that will be connected with the target PVInstance specified by [`JointsService:SetJoinAfterMoveTarget()`](https://rapi.sleaze.dev/classes/JointsService.md).

Parameters:

- `joinInstance`: The [`PVInstance`](https://rapi.sleaze.dev/classes/PVInstance.md) to be joined to the target set by [`JointsService:SetJoinAfterMoveTarget()`](https://rapi.sleaze.dev/classes/JointsService.md).

### SetJoinAfterMoveTarget

```luau
JointsService:SetJoinAfterMoveTarget(joinTarget: Instance)
```

- Tags: Capabilities: Physics

Sets the PVInstance that will be connected with the PVInstance specified by [`JointsService:SetJoinAfterMoveInstance()`](https://rapi.sleaze.dev/classes/JointsService.md).

Parameters:

- `joinTarget`: The [`PVInstance`](https://rapi.sleaze.dev/classes/PVInstance.md) to serve as the connection target for the instance set by [`JointsService:SetJoinAfterMoveInstance()`](https://rapi.sleaze.dev/classes/JointsService.md).

### ShowPermissibleJoints

```luau
JointsService:ShowPermissibleJoints()
```

- Tags: Capabilities: Physics

When used it will visibly display a potential surface connection between the two [`BasePart`](https://rapi.sleaze.dev/classes/BasePart.md), which were set with [`JointsService:SetJoinAfterMoveTarget()`](https://rapi.sleaze.dev/classes/JointsService.md) and [`JointsService:SetJoinAfterMoveInstance()`](https://rapi.sleaze.dev/classes/JointsService.md).
