Eden Editor: Introduction

Eden Editor is scenario editor introduced in Arma 3. It replaces previous 2D Editor, sharing many of its features, but add a wide range of new ones.

It's currently in beta, and you can find in in the dev-branch of the game.

Starting Eden Editor

Eden Editor can be used for designing both singleplayer and multiplayer scenarios. A singleplayer scenario can be tested directly on your computer, but previewing a multiplayer one requires server running in the background. While it's possible to host a server and start multiplayer preview of any scenario straight from the editor, you can also create a server before launching the editor.

Singleplayer Press EDITOR Select a terrain and press 3D EDITOR

Mutliplayer Press PLAY and then MULTIPLAYER to open server list Press NEW to host a server Set server parameters (or leave defaults) and confirm by OK The server is now created and you can see a list of scenarios for each terrain. To start a new scenario, pick <<New - 3D Editor>> option from the list and press PLAY or simply double-click on it.

Navigating the Scene

When the editor is opened, you'll be first greeted by a 3D Scene. The camera starts at randomized position, so you may sometimes discover completely unexpected locations.

The scene is useful for various scenario editing operations:

• Building object compositions
• Setting weather and time of day
• Tactical planning

The camera controls are based on character or vehicle controls in the game:

Control	Action
RMB Drag	Look around with the camera
Mouse wheel up / down	Move the camera towards / away from the screen center
W	Move the camera forward
S	Move the camera backward
A	Move the camera left
D	Move the camera right
Q	Move the camera up
Z	Move the camera down
Numpad8	Look up
Numpad2	Look down
Numpad4	Look left
Numpad6	Look right

Navigating the Map

You can also toggle a 2D topographic Map. Its appearance is the same as the map available when playing, including markers and entity icons.

The map is especially useful for following scenario editing operations:

• Setting scenario logic, e.g., triggers, waypoints or systems, where clear overview is more important than precise positioning
• Placing markers
• Strategic planning

The controls are shared with map controls everywhere else in the game:

Control	Action
RMB Drag	Move the map around
Mouse wheel up / down	Zoom the map in / out
W / Numpad 8	Move the camera forward
S / Numpad 2	Move the camera backward
A / Numpad 4	Move the camera left
D / Numpad 6	Move the camera right
