# maxAllowedRotationAngle(forJoint:)

Returns the rotation limit, in degrees, for the specified node.

## Declaration

```swift
func maxAllowedRotationAngle(forJoint node: SCNNode) -> CGFloat
```

## Parameters

- `node`: A node affected by the constraint—either the node whose doc://com.apple.scenekit/documentation/SceneKit/SCNNode/constraints property references the constraint or one of that node’s parent or ancestor nodes, up to the node specified by the constraint’s doc://com.apple.scenekit/documentation/SceneKit/SCNIKConstraint/chainRootNode property.

## Return Value

Return Value The maximum rotation, in degrees, that SceneKit applies to the specified node when evaluating the constraint.

## Discussion

Discussion When SceneKit evaluates the IK constraint, it checks the target orientations of each node in the chain relative to their initial orientations (as of when the constraint was applied to a node). For each node in the chain, SceneKit limits the rotation (in any direction) between the initial and target orientations to the value returned by this method. The default rotation limit for each joint is 180 degrees in either direction, allowing unconstrained rotation.
