A level being edited in the level builder.

The Level Builder is one of the main features of Mega Man Maker. Using the Level Builder, a user can create their own levels, save them as .MMLV level files, and share them with others. Players are also able to collaborate together over the internet in real time to build levels together using the Build Online feature of the Level Builder. Levels can be shared either by sending .MMLV files to others or by using the Online features to upload a level to Mega Man Maker's online server (after a play test to verify it is possible to complete) and shared with others.

Editor Toolbars

The Level Builder contains three different toolbars, each with different sets of tools and features.

Top Toolbar

This toolbar is focused on assets that can be placed within a created level.

Icon	Tool	Description
	Weapons	Button brings user to menu where they can select the usable weapons within the created level.
	Music	Button brings user to menu where they can select the music that will play within the created level, and listen to previews of each level music.

	Pickups	Button brings user to menu where they can select pickups and pickup spawners to place within the created level.
	Bosses	Button brings user to menu where they can select bosses, boss associated assets, and level ending assets to place within the created level.

These both appear in each of the assets menus associated to the Top Toolbar.

• Recents: Shows a listing of the last ten assets selected by the user.
• Favorites: Shows a listing of the ten or less favorite assets selected by the user. They can be added, removed, or re-arranged as the user desires.

Bottom Toolbar

This toolbar contains other useful tools unrelated to placing assets.

	Quick Tools	Button allows the user to choose between four drawing and selection methods: either draw freely, select a group of assets, fill in a group of solid tiles or fill in an outline with tiles. Holding right click with the fill in tools deletes assets instead.

	Map Toggle	Button toggles the ability or inability to see a map of all 1000 screens in the Level Builder.
	User Interface Toggle	Button toggles the ability or inability to see the various buttons and toolbars associated to the Level Builder. When the feature is disabled, moving the mouse to the far top or far bottom of the screen will cause the associated toolbars to re-appear until the mouse is moved away.

Layering

This article contains content that was added in a recent version. The contents of this article may change as more information is added.

This article is a stub. The content is too short and incomplete to warrant its own page. You can expand on it by adding content to this page. Reason: Unknown

Layering is a feature added in version 1.9.0 that allows assets to be placed and appear on different layers in the Level Builder.

Backgrounds

Backgrounds can be placed on one of two possible layers: a Back Layer and a Front Layer. Backgrounds featuring transparency are marked with a small T in the background selector and are now referred to as "T Backgrounds".

T Backgrounds can be placed on both the Back and the Front Layers, while non-T Backgrounds, i.e. fullscreen backgrounds that do not feature any transparency whatsoever, can only be placed on the Back Layer.

When a background is chosen, it will automatically be placed on the Back Layer. To place a T Background on the Back Layer instead, the icon for the Front Layer, shown on the right side of the screen, must be right-clicked, preventing backgrounds from being placed on it.

Assets

Shadows and water each have their own layer that appear in front of backgrounds. Certain assets such as lava and Chemical Solution also appear on the water layer. All other assets are assigned to one of five layers: far back, close back, main elements, close front, far front.

.MMLV File Format

Glitchy side-effects of improperly text editing a .MMLV file such as having a wide playable character.

.MMLV is the file format used to store data about a Mega Man Maker level.

These files can be edited with text editing programs such as Notepad. Editing the text in these files can change various aspects of the level, including removing limitations on what text characters can and cannot be used in a level's name, how long level names can be, and even how various assets in the level function.

Playing text edited level files may in some instances cause crashing, glitches, or other oddities to occur that otherwise would not. This could be caused by the player text editing certain values assigned to assets in ways they are not normally intended to be used.

To access .MMLV files saved in-game, they are located in %localappdata%/MegaMaker/Levels on a computer with a Windows operating system. The files may be in another location for computers running Windows through software such as Wine on other operating systems.

Trivia

This article contains information from an unknown source. While this information may be true, its validity needs to be confirmed. You can help by locating the origin of this info and linking the source next to the relevant text as a reference. Reason: "Luigi has stated that menus have a bit of empty space around them so users can click out of them."

• Luigi has stated that menus have a bit of empty space around them so users can click out of them.^{[source needed]}
• When a level has been named and saved at least once, the Level Builder will periodically attempt to autosave the level in case something goes wrong, such as crashes, softlocks, or the game suddenly closing. This may cause the game to lag while editing large levels.
• Placing the cursor over an icon in the Quick Tools menu will change the color of the icon, cycling through all of the UI colors except white.
