Arma 3: Eden Editor Event Handlers

Eden Editor event handlers. When added, they will remain until Eden Editor is closed. Playing preview will not erase them.

Editor Event Handlers

Editor handlers are added to the editor instance and will remain active for the duration of a session. Launching a preview won't erase them, but leaving to main menu will close the editor and erase all handlers with it.

Scripting

Commands:

• add3DENEventHandler
• remove3DENEventHandler

Example:

add3DENEventHandler ["onUndo",{hint "Undo";}]

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 be added automatically when Eden Editor is opened.

class Cfg3DEN
{
	class EventHandlers
	{
		class mySection
		{
			onUndo = "hint 'Undo';";
			// <handlerName> = <handlerExpression>
		};
	};
};

List

Most handlers don't receive any arguments. That is intended, because in most cases, required data can be obtained either using get3DENActionState, or by specialized 'get' commands.

Object Event Handlers

Editor specific event handlers can be also added directly to objects, using addEventHandler command.

These handlers exist only for the duration of active workspace. Running a preview or loading the same scenario again will erase all object event handlers, because objects themselves are despawned from the world and then created again.

List

Most handlers don't receive any arguments. That is intended, because in most cases, required data can be obtained either using get3DENActionState, or by specialized 'get' commands.

Class	Description	Arguments
AttributesChanged3DEN	When object's attributes are changed. Can happen when moving or rotating the object, when changing its attributes in attributes window, or when some scripts change attributes using set3DENAttributes command.	[object] object: Object - affected object
ConnectionChanged3DEN	When a connection is added or removed from an object.	[object] object: Object - affected object
RegisteredToWorld3DEN	When object is added to the scenario. That happens when you place it, but also when you paste it after copying, or when redoing placement operation after it was undone.	[object] object: Object - affected object
UnregisteredFromWorld3DEN	When object is removed from the scenario. That happens when you delete it, but also when you undo placement operation.	[object] object: Object - affected object
