Editor layers are separate “layers” you can sort objects into. When you're focused on a specific layer, you can only affect objects on that layer. This helps organize parts of your level, separating details for you to organize and edit individually.
You can go to layers by pressing the pink arrows next to the “All” text in the bottom right corner of the screen. Once you are on a different layer, an opaque blue arrow will appear; clicking it will bring you back to the “All” section.
The “All” section shows you every single layer, letting you modify every object in your level. After that, each layer is numbered and only focuses on that layer. All other layers will become see-through, and you will be unable to build, edit, or delete objects on those layers.
Placing objects while focused on a layer will automatically set their E layer to that layer. If you place objects down on the “All” section, those objects go to layer 0 by default.
If you have an object selected and press the Go To Layer button above the layer interface, you are brought to the layer that the object is in.
If you have the Show Object Info setting enabled from the editor pause menu, you can see which layers an object is on by selecting it and looking at the “EL:” category. This does not work when selecting multiple objects with different editor layers.
You can change what editor layer objects are on by selecting the objects and going to the Edit Group menu. At the top, there are two options for Editor L and Editor L2.
Here, you can assign two different editor layers for an object to be in. Pressing the blue plus button next to the labels will assign the object to the next unused layer.
0 is the default layer for Editor L2 and will be ignored as a value, meaning if Editor L is set to 5 and Editor L2 is at 0, the object will only appear on Editor Layer 5. If you want the object to be on Editor Layer 0, you must keep Editor L at 0.
If an object has more than two layers on it and you press Go To Layer, the layers will cycle between the two, starting with the value in Editor L2.
Editor locking prevents you from normally selecting or deleting objects from that layer, even from the “All” section. However, you can still place objects onto a locked layer.
You can also delete objects using the “Delete all of X Object” button in the delete tab, and you can select objects from locked layers using the “Select Filter” and the “Select All” buttons (more info in the next section).
You can “lock” editor layers if you have the Layer Locking setting enabled, found in the settings menu within the editor's pause menu. To toggle between locking and unlocking a layer, click the layer number on the layer interface. The number will be orange when locked and white when unlocked.
To unlock all layers in your level, press the Unlock Layers button at the right of the editor pause menu.
Select Filter is a setting you can enable in the editor pause menu. It lets you select objects with specific attributes, which you can set in the Delete tab. When you're there, you'll see these buttons.
The top left button is the Find GroupID button. It doesn’t have anything to do with select filter, but it selects a random object with the targeted ID for you.
Next to it, you can find two buttons with a "0" on them. The top button is for filtering out GroupIDs, and the button below is for filtering out Color Channels. The Color Filter also has options to select Special Colors by pressing the blue plus button: Obj, Lighter, 3DL, P1, and P2.
While these are enabled, you can only select objects with the specified group or color channel. The value of zero means the filter is off. The trash button in the top right of the filter menus resets the current filter, while the one next to these filters resets them both.
Out of the four right buttons, the bottom right button is the only one that works with select filter. It lets you select objects of the same object type as your currently selected object.
Choosing None will revert the selection to normal. Static deletes static objects like blocks, which have a hitbox. Details targets everything else.
Select All selects every object in the current editor layer. You can do this by pressing one of the three select all buttons in the editor pause menu.
Select All: Selects every object in the current editor layer.
Select All Left: Selects every object to the left of the center of the screen (indicated by an opaque vertical line on the screen).
Select All Right: Selects every object to the right of the center of the screen.
