enum SpaceOverride:
- SPACE_OVERRIDE_DISABLED = 0 — This area does not affect gravity/damping.
- SPACE_OVERRIDE_COMBINE = 1 — This area adds its gravity/damping values to whatever has been calculated so far (in order).
- SPACE_OVERRIDE_COMBINE_REPLACE = 2 — This area adds its gravity/damping values to whatever has been calculated so far (in priority order), ignoring any lower priority areas.
- SPACE_OVERRIDE_REPLACE = 3 — This area replaces any gravity/damping, even the defaults, ignoring any lower priority areas.
- SPACE_OVERRIDE_REPLACE_COMBINE = 4 — This area replaces any gravity/damping calculated so far (in order), but keeps calculating the rest of the areas.
Description
3D area that detects CollisionObject nodes overlapping, entering, or exiting. Can also alter or override local physics parameters (gravity, damping).
- angular_damp
Setter | set_angular_damp(value) |
Getter | get_angular_damp() |
- String audio_bus_name
Setter | set_audio_bus(value) |
Getter | get_audio_bus() |
The name of the area’s audio bus.
- audio_bus_override
Setter | set_audio_bus_override(value) |
Getter | is_overriding_audio_bus() |
If true
, the area’s audio bus overrides the default audio bus. Default value: false
.
- int collision_layer
Setter | set_collision_layer(value) |
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 .
- int collision_mask
The physics layers this area scans to determine collision detection.
- gravity
Setter | set_gravity(value) |
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.
- float gravity_distance_scale
Setter | set_gravity_distance_scale(value) |
Getter | get_gravity_distance_scale() |
The falloff factor for point gravity. The greater the value, the faster gravity decreases with distance.
- gravity_point
Setter | set_gravity_is_point(value) |
Getter | is_gravity_a_point() |
If true
, gravity is calculated from a point (set via gravity_vec). Also see . Default value: false
.
- Vector3 gravity_vec
Setter | set_gravity_vector(value) |
Getter | get_gravity_vector() |
The area’s gravity vector (not normalized). If gravity is a point (see ), this will be the point of attraction.
- float linear_damp
Setter | set_linear_damp(value) |
Getter | get_linear_damp() |
The rate at which objects stop moving in this area. Represents the linear velocity lost per second. Values range from 0
(no damping) to 1
(full damping).
If , other monitoring areas can detect this area. Default value: true
.
- monitoring
Setter | set_monitoring(value) |
Getter | is_monitoring() |
If true
, the area detects bodies or areas entering and exiting it. Default value: true
.
- float priority
Setter | set_priority(value) |
Getter | get_priority() |
The area’s priority. Higher priority areas are processed first. Default value: 0.
- reverb_bus_amount
Setter | set_reverb_amount(value) |
Getter | get_reverb_amount() |
- bool reverb_bus_enable
Setter | set_use_reverb_bus(value) |
Getter | is_using_reverb_bus() |
If true
, the area applies reverb to its associated audio.
- reverb_bus_name
Setter | set_reverb_bus(value) |
Getter | get_reverb_bus() |
The reverb bus name to use for this area’s associated audio.
- float reverb_bus_uniformity
The degree to which this area’s reverb is a uniform effect. Ranges from to 1
with 0.1
precision.
- space_override
Setter | set_space_override_mode(value) |
Getter | get_space_override_mode() |
Override mode for gravity and damping calculations within this area. See SpaceOverride for possible values.
Method Descriptions
- get_collision_layer_bit ( int bit ) const
Returns an individual bit on the layer mask.
- get_collision_mask_bit ( int bit ) const
Returns an individual bit on the collision mask.
- get_overlapping_areas ( ) const
Returns a list of intersecting Area
s. For performance reasons (collisions are all processed at the same time) this list is modified once during the physics step, not immediately after objects are moved. Consider using signals instead.
- Array get_overlapping_bodies ( ) const
Returns a list of intersecting s. For performance reasons (collisions are all processed at the same time) this list is modified once during the physics step, not immediately after objects are moved. Consider using signals instead.
- bool overlaps_area ( area ) const
If true
, the given area overlaps the Area. Note that the result of this test is not immediate after moving objects. For performance, list of overlaps is updated once per frame and before the physics step. Consider using signals instead.
- bool overlaps_body ( body ) const
If true
, the given body overlaps the Area. Note that the result of this test is not immediate after moving objects. For performance, list of overlaps is updated once per frame and before the physics step. Consider using signals instead.
- void set_collision_layer_bit ( int bit, value )
Set/clear individual bits on the layer mask. This simplifies editing this Area
’s layers.
- void set_collision_mask_bit ( int bit, value )
Set/clear individual bits on the collision mask. This simplifies editing which Area
layers this scans.
