Hierarchy/Create
Hierarchy
This sub-panel lists entities present in the world. Entities are grouped into layers for clarity.
Red = Entity
Blue = Prefab
Create
This sub-panel is a quick access to scripted entities that can be created in the world. Such entities can be user-defined by the EntityEditorProps class attribute.
Viewport
This is the 3D world render that allows to edit terrain or preview a mission setup.
By default, pressing Esc leaves the preview; F10 is a hardcoded equivalent to Esc (within World Editor) and can be used as a counterpart.
Object Properties/Tool Properties
Object Properties
This sub-panel is divided in sections - appearing sub-panels depend on the Entity's type; only the most common are described here:
Entity information
The Entity's root type is listed on the left, and on the right is a field to name the entity to be able to refer to it by script.
Components are then listed under the class.
The scope of changes brought in this interface can be set to the entity instance, the entity definition itself, modded entities, or the parent prefab(s).
Transformation
A way to change a lot of position and orientation values:
- coordinates
- angles
- scale (in range 0..1000)
General
Flags
- Traceable: the Entity can be detected via tracing methods
- Visible: the Entity is invisible in-game (still being visible in World Editor)
- Static: the Entity is expected to remain in position and will not be moved around
- Feature: the Entity is a "feature" of the terrain and will be drawn no matter the distance
- Proxy: the Entity is a sub-element of a prefab and should be hidden when the parent prefab is
- Editor Only: the Entity is present only in the editor
- Relative Y: the Entity's altitude will be relative to the surface below it
Script
Provide script "slots" for events and/or other cases
Unsorted
The uncategorised available settings.
Tool Properties
This sub-panel changes depending on the currently selected tool.
Viewport
With the mouse wheel alone 
you can move the camera forward and backward.
With the right mouse button 
pressed:
- By moving the mouse, you can change the orientation of the camera.
- The mouse wheel changes the speed at which the camera moves - scroll up to increase the speed, scroll down to decrease it.
- Use the W and S keys to move the camera forward and backward along the camera orientation at the set speed.
- Use the A and D keys to move the camera sideways.
- Use the Q and Z keys to move the camera up and down.
Double-clicking an entity in the Hierarchy subwindow focuses the camera on that entity. Pressing the F key focuses on the currently selected entity as well.
Resource Browser/Prefab Library
Both Resource Browser and Prefab Library are content browsers, and use a color code underlight for entity (.et) types:
- blue: regular prefabs
- purple: Prefab Library entity
- orange: editable Prefab (used by in-game editor)
Resource Browser
The Resource Browser provides a view of all the data present and available in the game's data as well as the user's profile directory.
It shows the project's data structure (see Directory Structure) and displays every data type (e.g. config, textures but also prefabs, etc.).
Prefab Library
The Prefab Library offers an interface to browse Prefabs that are available in the game's data.
Unlike the Resource Browser, it does not display content from sub-directories in the Entity Tab. Prefab Library is also not available in Resource Manager, since its closely tied to world creation process.
Prefabs are sorted by categories, represented by directories present in Data\PrefabLibrary (see Directory Structure):
- Decals
- Generators
- Infrastructure
- Props
- Rocks
- Structures
- Vegetation
- Walls
Directory Tab
This shows the directory structure and allows the wanted directory to be picked.
Entity Tab
This lists the entities found in the open directory.
Details Tab
This tab is filled only when an entity is highlighted in the Entity Tab.
| Entry | Description |
|---|---|
| Place By | Two options:
|
| Random Yaw | Determine if a random yaw (Y-axis rotation, direction) should be applied on object's placement. Randomization is applied in a 0..360° range |
| Align To Normal | Set if yes or no the entity should be placed perpendicular (normal) to the surface on which it is |
| Random Scale | Define whether or not the entity should be randomly scaled, between min-max set values |
| Random Vert Offset | Random Vertical Offset - define whether or not the entity should have a random vertical offset, between min-max (possibly negative) set values |
| Random Pitch Angle | Define if and how much of a random pitch ("front/back roll") should be applied to the entity |
| Random Roll Angle | Define if and how much of a random roll ("left/right (barrel) roll") should be applied to the entity |
Log Console
The Log Console displays error, warning and informative messages. It can be cleaned by pressing the Clear Console button.
It also displays three buttons that can be combined:
- Show only error messages: only shows "Error" and "Fatal" logs
- Show only warning messages: only shows "Warning" logs
- Show only info messages: only shows "Spam", "Verbose", "Debug", "Normal" logs
If no buttons are selected, the Log Console shows all the messages.
The last button, Filter Options, allows for advanced filtering as shown on the side.
