Mapping

Mapping is the process of building and creating maps, the basis of DDNet's (and other modes') gameplay. Maps can be created by anyone, given they have the will and creativity to do so.

Mapping also allows users to add their own design, sound, and aesthetic to maps, and can also be used for entities backgrounds, main menu themes, and more.

DDNet allows players to submit their own race maps on the DDNet Discord, where respective rules and guidelines can also be found.

Players can access the map editor interface by clicking on the editor in the main menu.

From any in-game screen, pressing ctrl+⇧ Shift+E will also take you directly to the map editor screen.

Overview of the Editor Interface

TODO: Update the interface section with visuals and instructions for the new editor visuals

Each labeled button in the editor interface has the following functionalities:

[1] File

File drop-down menu content

Opens a drop-down menu to create, load and save map files.

[11] Zoom

Field of view adjustment functionality.

Expanding or scaling the field of view by clicking buttons or pressing shortcut keys has no maximum and minimum scale value, and the scale value can even reach negative values. When the scale value is negative, the map as a whole is upside down.

• - (Zoom out) numpad-: expands the field of view of the operation area by 50 points of scale value each time.
  • Scrolling the mouse wheel down also expands the field of view by 20 scale points per scroll, expanding the field of view in this way up to a maximum of 2000 scale points.
• Zoom numpad*: restores the field of view to the default scale value.
• + (Zoom in) numpad+: reduces the field of view of the operation area by 50 points of scale value at a time.
  • Roll the mouse wheel upward to also reduce the field of view by 20 scale points per scroll frame, and reduce the field of view in this way up to 10 scale points.

[12] Undo/Redo

Comments can also be added at the end of a command or as a separate line using the # symbol.

[19] Envelopes

Example animation of a basic color change

Opens a resizable window that can be used to animate various things in your map.

TODO: Explain how to use the env. editor

The animation ingame

To make an envelope, click on either the Pos+, Color+ or Sound+ buttons. On any envelope, going from left to right, you have:

• Envelope selection - Click either the - or + symbols to go back and forth. The left value shows you which envelope you're on and the right value shows you how many envelopes there are in total.
  • The field is green or red, depending on if the envelope is in use or not.
• Name field - Use this to give a name to your envelope for better organization.
  • The name is optional, and can be left blank.
• Envelope values - These values change depending on the envelope type (position, color, sound)
• Sync - Optionally synchronize this envelope to the server time, instead of the client time.
• Zoom - Zooms out the envelope editor. Holding ⇧ Shift zooms out vertically.
  • You can also use the scroll wheel to zoom, or simply click the middle magnifying glass to automatically fit the entire curve in the editor.
• Envelope repositioning - Use either button to move the envelope in the list of envelopes, as seen in the envelope selection.
• X - Delete the current envelope
• Pos+ - Will create a position envelope
  • Position envelopes have 3 values: The X-axis (X), the Y-axis (Y) and the rotation (R).
  • Position envelopes can only be applied to quads, by right clicking their pivot, the green square, and selecting a Pos. Env.
• Color+ - Will create a color envelope
  • Color envelopes have 4 values: Red (R), green (G), blue (B) and opacity or alpha (A).
  • Color envelopes can be applied to tile layers and quads, but not quad layers. Either right click a tile layer in the layer section or the pivot of a quad.
  • By right clicking a point in the editor, you're able to use a color picker, instead of manually editing the individual values.
• Sound+ - Will create a sound envelope
  • Sound envelopes have only one value: Volume (V)
  • Sound envelopes can only be applied to individual sounds and not the layer, similar to quads.
• Undo/redo - Will undo or redo the last change in the envelope editor. Also see history

The Basics of Mapping

Moving around in the editor can be done with either wasd or middle click. Maps typically consist of quads and tiles, which separate into game tiles and visual tiles.

Explanations of the game tiles can be seen on this site. As their names imply, game tiles are what your tee interacts with, while visual tiles serve as decoration, or as a way to mark game tiles in design.

To place tiles, first select a tile layer from the layer section and hold down space Pick a tile to place by left clicking it and making a brush. Place tiles by releasing space and holding down left click and moving your mouse. Brushes can be cleared with right click.

Quads can be placed on the map by selecting a quad layer, then clicking on Add quad at the top. Quads can be changed in multiple ways.

• Resizing the quad is done by holding down left click on one of the red dots at the corners and dragging them around

• Recoloring the quad is done either trough color envelopes or trough right clicking the red dots at the corners and using the color picker

• Moving the quad is done by holding down left click on the green dot at the middle of the quad and dragging it around
  • Holding ⇧ Shift while doing so will move around the pivot point of the quad, which is useful for:

• Rotating the quad, which is done either trough position envelopes or by tapping r after clicking the green pivot once.

Generally, quads should only be used when using tiles isn't viable, since quads are worse on performance and the map's file size than normal tiles. For example: the map background, the logo and credits of the map or decorations that can't be made with tiles.

See LAN Server or Trashmap for info about hosting and testing your map in game.
