A layer is like a folder that can contain multiple entities of type object, group, trigger, waypoint, system or marker. 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 and fill it with entities as shown in the previous section.
2. Select all entities in that layer and uncheck Show Model and Enable Simulation in the attributes

3. Preview the scenario
4. Open the Arma 3: Debug Console and execute the following code: (flatten getMissionLayerEntities "QRF") apply { _x enableSimulationGlobal true; _x hideObjectGlobal false; };// This will show all entities inside the layer and enable their simulation

⚠

Always be aware of what kind of entities are inside your layer. To hide markers for example, set their Alpha value to 0 inside Eden Editor and use setMarkerAlpha during the scenario.
