# Asteroid Editor

Opens via Editors › Asteroid Editor.

Configures the single asteroid field that can exist in a mission. The field is defined by a rectangular outer bounding box.

## Field type

Option | Description
--- | ---
Active | The field actively throws asteroids at ships. New asteroids are aimed directly at the ships listed in the Targets section of this editor.
Passive | Asteroids drift freely and do not target ships.

## Object type

Option | Description
--- | ---
Asteroid | Spawns large asteroids that split into medium and small pieces when destroyed.
Debris | Spawns specific debris pieces chosen from a weighted list. Debris does not split when destroyed.

## Key fields

Field | Description
--- | ---
Enabled | Adds the field to the mission. Uncheck to disable it.
Number | The number of asteroid or debris objects present in the field at any one time.
Avg speed | Base speed of objects in the field. Each individual object's speed is randomized around this value; the actual range depends on the current skill level and the object's maximum speed as defined in the table.

## Outer box

The bounding box of the field. Set the Min and Max coordinates on each axis to size and position the box.

## Inner box

When enabled, defines an exclusion zone inside the outer box where objects will not spawn. Any object that would appear inside the inner box is repositioned just outside it.

## Use Enhanced

Changes how the engine decides whether to spawn a new asteroid or wrap an existing asteroid when it leaves the outer box. By default, the engine checks both the player's view cone and a maximum distance range. When Enhanced is enabled, the distance range check is skipped and only the view cone is used.
