A group is a composition of characters which are linked together in a command structure.

General Information


A group is created when a new character is placed. However, if the character is near another one of the same side, it will be grouped to it instead. This functionality can be disabled using the Automatic Grouping attribute in the editor preferences.


A group always has a leader who is able to issue orders to the other group members. Usually, the highest ranking character is the leader, and if he dies, the second highest ranking character takes his place. You can manually change the group leader using the grouping connection or the context menu. The character you connect others to will become the leader.


The group side dictates its relation with other groups, e.g. characters in BLUFOR groups will engage those in OPFOR groups. A character inherits the group side, even if its own side is different. For example, an OPFOR character grouped to a BLUFOR group will be BLUFOR as well.

Groups in the Eden Editor

A group is represented by an icon hovering above the leader's position. Lone units do not have the icon visible unless they are selected. Clicking on the icon will select all group members. When zoomed out, the icons of nearby group members are stacked together with the group icon.

In the entity list, a group is represented as a folder with all its members and waypoints placed inside. Only a whole group can be moved between layers, not its individual members. Dragging one member will move the rest of the group as well.

Sorting characters into logical groups can speed up designing your scenario, make sure to use them well.
