Wind areas define a location within which objects experience wind. If no direction is set, wind moves omnidirectionally from the center of the wind area.

To create a wind area

  1. In the Rollup Bar, under Objects, click Entity.

  2. Under Browser, expand Physics and double-click WindArea.

  3. Drag to place the entity in your level. A bounding box with direction areas appears.

  4. Under Entity Properties, adjust values of the following parameters:

    • Active – Enables or disables wind inside the area.

    • AirDensity – If greater than 0, causes objects moving through the air to slow down.

    • AirResistance – If greater than 0, causes lightweight objects to experience buoyancy.

    • Ellipsoidal – Specifies an ellipsoidal drop off in air speed.

    • FalloffInner – Sets the distance at which distance-based air speed begins to drop off.

    • Speed – Sets the wind speed.

    • Dir – Sets the wind direction.

    • Size – Sets the size of the wind area.
