Eden Editor: Layer

A layer is like a folder that can contain multiple entities of type object, group, trigger, waypoint, system or marker. They can also contain sub-layers. Layers can be useful in various ways such as:

• Tidying up the editor view while editing by hiding the layers and their entities
• Grouping certain entities together thematically
• Preventing a group of entities from being accidentally edited by disabling transformation
• Dynamically creating the entities within a layer during the scenario

Creating a layer

There multiple ways to create layers:

1. Select entities in the 3D or map view or the entity list (left panel) and press the New Layer button in the entity list
   
2. Use the add3DENLayer scripting command
   

ⓘ

Pressing the New Layer button without having entities selected will create an empty layer

Deleting a layer

Layers can be deleted by either selecting them in the entity list and pressing the Del key or using the Delete button in the entity list.

⚠

Deleting a layer will also delete all sub-layers and entities within it!

Dynamically create layer entities

One advantage of layers is that they can be used to hide or show all entities within the layer dynamically via scripting during a scenario.

1. Create a layer, name it NewAO and add some objects and markers to it.
2. Select all objects in that layer and uncheck Show Model and Enable Simulation in the attributes. In case of markers, set the Alpha value to 0
   
   
3. Preview the scenario
4. All objects and markers will now be invisible
5. Open the Arma 3: Debug Console and execute the following code. If you use want to activate the layer via a trigger, make sure to check the Server only checkbox
   getMissionLayerEntities "NewAO" params ["_objects", "_markers"]; // The command returns an array with two arrays. First array contains all objects, second array contains all makers _markers apply { _x setMarkerAlpha 1; }; // Show all markers _objects apply { _x enableSimulationGlobal true; _x hideObjectGlobal false; }; // Show all entities and enable their simulation
