rotationEnabled

Rotationenabled, often written as rotationEnabled in source code, is a boolean flag that indicates whether a given object, component, or UI element is permitted to rotate. It is used across software development, game engines, robotics, and 3D modeling to control rotational transformations without changing position or scale.

In practice, when rotationEnabled is true, rotation transformations driven by user input, physics, or animation may apply. When it is false, the object maintains a fixed orientation regardless of other transformations. The flag is commonly part of a transform or component data structure and may be serialized to and from JSON or other data formats, enabling the state to be saved and restored.

Naming and usage conventions vary by language and framework. In languages that favor camelCase, the field is often named rotationEnabled; in those that prefer snake_case, it may appear as rotation_enabled. It is frequently used in conjunction with axis constraints, such as locking rotation on specific axes or providing alternate rotation orders. In physics-enabled environments, disabling rotation can be achieved by setting corresponding constraints, while in UI contexts, rotationEnabled determines whether a draggable control or object responds to rotation gestures.

Examples of typical behavior include a spinning compass needle controlled by rotationEnabled, or a door model that only opens or closes without rotating its base when rotationEnabled is false. Proper use of the flag helps manage performance, physics stability, and user experience, ensuring that rotation occurs only when intended and predictable.
