Overview

The area objects are used to create three dimensional zones in the level that can be used to trigger events. Access the Area Objects via the Create Object tool.

Box

This entity lets you create a box to which you can link triggers and other entities that should be enabled when the player enters or leaves the box.

Params

Descriptions

AreaId

Sets up the ID of the area, so areas with another ID can overlap.

FadeInZone

Specifies in meters how big the zone around the box is that is used to fade in the effect attached to the box.
Only when the player is inside the box the effect is rendered at 100%, at the beginning of the FadeInZone its rendered at 0%.

Width

Specifies how wide the box is.

Length

Defines how long the box is.

Height

Specifies how high the shape area should be (0 means infinite height).

GroupId

Sets up the Group ID of the area, so areas with another group ID can overlap.

Priority

Defines the Priority so areas with a higher priority will be processed first.

ObstructRoof

DEPRECATED - This enables if the roof should be obstructed.

ObstructFloor

DEPRECATED - This enables if the floor should be obstructed.

Filled

Just for visibility in the editor this option defines if the area should be rendered as filled or not.

DisplaySoundInfo

Enable to expand Sound Obstruction options.

Solid

Please see the AreaSolid documentation for more information.

Sphere

To the AreaSphere you can link triggers and other entities that should be enabled when the player enters or leaves the sphere.

Params

Descriptions

AreaId

Sets up the ID of the area, so areas with another ID can overlap.

FadeInZone

Specifies in meters how big the zone around the box is that is used to fade in the effect attached to the box. Only when the player is inside the box the effect is rendered at 100%, at the beginning of the fadeinzone its rendered at 0%.

Radius

Specifies how big the sphere should be.

GroupId

Sets up the Group ID of the area, so areas with another group ID can overlap.

Priority

Defines the Priority so areas with a higher priority will be processed first.

Filled

Just for visibility in the editor this option defines if the area should be rendered as filled or not.

OccluderArea

An Occluder Area allows you to create an occlusion plane out of a custom shape with multiple edges, unlike an Occluder Plane object which can only be a square shape.

The purpose of this object is to stop the engine from rendering everything that is behind it. It is used for performance optimization in areas where automatic occlusion from brushes and terrain don't work very well.

Params

Descriptions

DisplayFilled

Just for visibility in the editor this option defines if the area should be rendered as filled or not.

CullDistRatio

Specifies at what distance the culling effect should stop occurring.

UseIndoors

Specifies if the occluder area should be working inside an indoor visarea.

OccluderPlane

An Occluder Plane can be used to occlude objects behind the plane. Like Occluder Area's, this typically isn't required because occlusion is done automatically through the assets, these can be used as a fallback method.

Params

Descriptions

Height

Specifies how high the occluder plane is.

DisplayFilled

Just for visibility in the editor this option defines if the plane should be rendered as filled or not.

CullDistRatio

Specifies at what distance the culling effect should stop occurring.

UseIndoors

Specifies if the occluder plane should work inside a visarea.

DoubleSide

Specifies if the occluder plane should work from both sides.

Portal

Please see the Vis Area and Portal documentation pages for more information.

Shape

This object lets you create a shape to which you can link triggers and other entities that should be enabled when the player enters or leaves the area shape.

Params

Descriptions

Width

Specifies how wide the entity is.

Height

Specifies how high the shape area should be (0 means infinite height).

AreaId

Sets up the ID of the area, so areas with another ID can overlap.

GroupId

Sets up the Group ID of the area, so areas with another group ID can overlap.

Priority

Defines the Priority so areas with a higher priority will be processed first.

Closed

Sets if the area should be closed or if it should be just a line.

ObstructRoof

DEPRECATED - This enables if the roof should be obstructed.

ObstructFloor

DEPRECATED - This enables if the floor should be obstructed.

DisplayFilled

Just for visibility in the editor this option defines if the area should be rendered as filled or not.

DisplaySoundInfo

Enable to expand Sound Obstruction options.

Agent_height

When Render_voxel_grid is enabled this determines the height - along the y axis - of the grid cells rendered.

Agent_width

When Render_voxel_grid is enabled this determines the height - along the x axis - of the grid cells rendered.

Render_voxel_grid

If true, voxel grid will be rendered when helpers are enabled.

voxel_offset_x

Offset voxel grid on the X axis.

voxel_offset_y

Offset voxel grid on the Y axis.

WaterVolume
