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.

Related commands

Event Scripts

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

ⓘ
  • Most handlers do not receive any arguments; this is intended, as in most cases required data can be obtained using either get3DENActionState or specialised 'get*' Eden Editor commands.
  • Note that unlike object's or mission's event handlers, the On prefix is present in both config and command event name.

Init

Is executed when Eden Editor display was created. Only happens when Eden Editor is opened for the first time during game session.

add3DENEventHandler ["Init", { params ["_display3DEN"]; }];

OnConnectingStart

When Connecting operation is initiated.

add3DENEventHandler ["OnConnectingStart", { params ["_class", "_from"]; }];


OnConnectingEnd

When Connecting operation is terminated, no matter if it was confirmed or canceled.

add3DENEventHandler ["OnConnectingEnd", { params ["_class", "_from", "_to"]; }];

  • 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.

add3DENEventHandler ["OnCopy", { // no arguments }];


OnCut

Fires when entities are cut (after the entities have been deleted).

add3DENEventHandler ["OnCut", { // no arguments }];


OnDeleteUnits

When entities are deleted.

add3DENEventHandler ["OnDeleteUnits", { // no arguments }];


OnEntityMenu

When Entity Context Menu is opened.

add3DENEventHandler ["OnEntityMenu", { params ["_position", "_entity", "_listPath"]; }];

  • position: Array - Position where user clicked to open the menu.
    • Entity position when clicked on an entity.
    • 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)


OnGridChange

When grid changes, either using Toolbar option, ot by scripting command set3DENGrid.

add3DENEventHandler ["OnGridChange", { params ["_gridType", "_gridValue"]; }];

  • gridType: String - can be "translation", "rotation" or "scaling"
  • gridValue: Number

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.

Events

ⓘ
Most handlers do not receive any arguments. This is intended, because in most cases, required data can be obtained using either get3DENActionState or specialised 'get' commands.

AttributesChanged3DEN

Fires when object's attributes are changed. Can happen when:

  • Changing the attributes by dragging, rotating or using one of the widgets
  • Changing and saving the attributes from within the attributes window
  • When attributes get changed using scripting commands such as set3DENAttributes or set3DENAttribute

Unlike Dragged3DEN this event handler will not fire continuously but only when the attributes were changed and saved

edenObject addEventHandler ["AttributesChanged3DEN", { params ["_object"]; }];

  • object: Object - affected object


ConnectionChanged3DEN

When a connection is added or removed from an object.

edenObject addEventHandler ["ConnectionChanged3DEN", { params ["_object"]; }];

  • object: Object - affected object


RegisteredToWorld3DEN

When object is re-added to the scenario after undoing a delete operation.

edenObject addEventHandler ["RegisteredToWorld3DEN", { params ["_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.

edenObject addEventHandler ["UnregisteredFromWorld3DEN", { params ["_object"]; }];

  • object: Object - affected object


Dragged3DEN

When object is dragged and/or rotated. Also triggers when widgets are used to manipulate position and orientation. Does not trigger when the object's size is changed.

edenObject addEventHandler ["Dragged3DEN", { params ["_object"]; }];

  • object: Object - affected object
