A layer is like a folder that can contain multiple entities of type [[#Object|object]], [[#Group|group]], [[#Trigger|trigger]], [[#Waypoint|waypoint]], [[#System|system]] or [[#Marker|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:<br/>
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<br/>
2. Use the [[add3DENLayer]] scripting command<br/>
{{Feature|informative|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 {{KeyboardShortcut|Del}} key or using the ''Delete'' button in the entity list.
{{Feature|Important|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 [[:Category: Scripting Topics|scripting]] during a scenario.<br/><br/>
1. Create a layer, name it ''NewAO'' and add some objects and markers to it.<br/>
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 <tt>0</tt><br/>

3. Preview the scenario<br/>
4. All objects and markers will now be invisible<br/>
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
<code>[[getMissionLayerEntities]] "NewAO" [[params]] ["_objects", "_markers"]; {{cc|The command returns an array with two arrays. First array contains all objects, second array contains all makers}}
_markers [[apply]] { _x [[setMarkerAlpha]] 1; }; {{cc|Show all markers}}
_objects [[apply]] { _x [[enableSimulationGlobal]] [[true]]; _x [[hideObjectGlobal]] [[false]]; } {{cc|Show all entities and enable their simulation}}</code>
