Eden Editor Event Handlers – Arma 3
Editor Event Handlers
Eden Editor Event Handlers are added to the editor instance and will remain active for the duration of a session. Launching a preview will keep the event handlers, but closing the editor will erase all of them and you will have to add them again on the next Eden instance.

Config
Alternatively, you can define event handlers directly in the config. Use your custom section (mySection in the example) to prevent overriding handlers from other sources. Handlers defined here will automatically be added when Eden Editor is opened.
class Cfg3DEN
{
class EventHandlers
{
class mySection
{
onUndo = "hint 'Undo';";
// <handlerName> = <handlerExpression>
};
};
};
Events
The following Magic Variables are available inside the event's code:
- Event Handler parameters are accessible via c_this (only if event has parameters)
- The Event Handler type is available as c_thisEvent
- The Event Handler index is available as c_thisEventHandler
Init
Is executed when Eden Editor display was created. Only happens when Eden Editor is opened for the first time during game session, only available through config modding.
init = " params ['_display3DEN']; systemChat 'First Eden launch this session'; ";
- display3DEN: Display
OnBeforeMissionPreview
Runs before the scenario preview is started. If an event handler of this type returns true, the mission preview will not be initialised.
OnConnectingStart
When Connecting operation is initiated.
- class: Config - connection config class
- from: Array of Eden Entities
OnConnectingEnd
When Connecting operation is terminated, no matter if it was confirmed or canceled.
- class: Config - connection config class
- from: Array of 3DEN entities
- to: Eden Entity (when connecting was successful) or nil (when connecting was terminated)
OnCopy
Fires when entities are copied.
Also fires when entities are cut, but unlike OnCut, OnCopy fires before the entities are deleted, meaning the entities are still accessible with get3DENSelected.
OnCut
Fires when entities are cut (after the entities have been deleted).
OnDeleteUnits
When entities are deleted.
OnEditableEntityAdded
When an entity gets added to the scenario. When compositions are added, the event triggers for every entity in the composition.
entity - Eden Entity
OnEditableEntityRemoved

entity - Eden Entity
OnEntityAttributeChanged
When an entity's attribute got changed. Fires for each changed attribute separately.

entity - Eden Entity
OnEntityMenu

- Empty array when clicked on something that doesn't have position (i.e. abstract folder in Edit list like BLUFOR, Trigger, etc.)
- entity: Eden Entity
- Nil when clicked on empty space
- listPath: Array - UI tree path when clicked on entity in the entity list.
- Nil when clicked in the scene (we cannot use empty array, because that's a path to root item)
