<members>
<member name="angular_damp" type="float" setter="set_angular_damp" getter="get_angular_damp">
The rate at which objects stop spinning in this area. Represents the angular velocity lost per second. Values range from [code]0[/code] (no damping) to [code]1[/code] (full damping).
</member>
<member name="audio_bus_name" type="String" setter="set_audio_bus_name" getter="get_audio_bus_name">
The name of the area's audio bus.
</member>
<member name="audio_bus_override" type="bool" setter="set_audio_bus_override" getter="is_overriding_audio_bus">
If [code]true[/code] the area's audio bus overrides the default audio bus. Default value: [code]false[/code].
</member>
<member name="collision_layer" type="int" setter="set_collision_layer" getter="get_collision_layer">
The area's physics layer(s). Collidable objects can exist in any of 32 different layers. A contact is detected if object A is in any of the layers that object B scans, or object B is in any layers that object A scans. See also [code]collision_mask[/code].
</member>
<member name="collision_mask" type="int" setter="set_collision_mask" getter="get_collision_mask">
The physics layers this area scans to determine collision detection.
</member>
<member name="gravity" type="float" setter="set_gravity" getter="get_gravity">
The area's gravity intensity (ranges from -1024 to 1024). This value multiplies the gravity vector. This is useful to alter the force of gravity without altering its direction.
</member>
<member name="gravity_distance_scale" type="float" setter="set_gravity_distance_scale" getter="get_gravity_distance_scale">
The falloff factor for point gravity. The greater the value, the faster gravity decreases with distance.
</member>
<member name="gravity_point" type="bool" setter="set_gravity_is_point" getter="is_gravity_a_point">
If [code]true[/code] gravity is calculated from a point (set via [code]gravity_vec[/code]). Also see [code]space_override[/code]. Default value: [code]false[/code].
</member>
<member name="gravity_vec" type="Vector2" setter="set_gravity_vector" getter="get_gravity_vector">
The area's gravity vector (not normalized). If gravity is a point (see [method is_gravity_a_point]), this will be the point of attraction.
</member>
<member name="linear_damp" type="float" setter="set_linear_damp" getter="get_linear_damp">
The rate at which objects stop moving in this area. Represents the linear velocity lost per second. Values range from [code]0[/code] (no damping) to [code]1[/code] (full damping).
</member>
<member name="monitorable" type="bool" setter="set_monitorable" getter="is_monitorable">
If [code]true[/code] other monitoring areas can detect this area. Default value: [code]true[/code].
</member>
<member name="monitoring" type="bool" setter="set_monitoring" getter="is_monitoring">
If [code]true[/code] the area detects bodies or areas entering and exiting it. Default value: [code]true[/code].
</member>
<member name="priority" type="float" setter="set_priority" getter="get_priority">
The area's priority. Higher priority areas are processed first. Default value: 0.
</member>
<member name="space_override" type="int" setter="set_space_override_mode" getter="get_space_override_mode" enum="Area2D.SpaceOverride">
Override mode for gravity and damping calculations within this area. See the SPACE_OVERRIDE_* constants for values.
