The Puzzle Creator (also known as Puzzle Maker or Editor) is a part of the Perpetual Testing Initiative in Portal 2, a DLC released on May 8th, 2012[1] allowing the creation of single-player and Co-op test chambers within a simple in-game editor.[1]

In order to create a Co-operative puzzle, the chamber must be marked as a "Co-operative puzzle" in the "File" menu of the Puzzle Creator.

Overview

The editor was first mentioned within The Final Hours of Portal 2, "[An in-game level browser won't be of much use unless] Valve figures out how to make designing Portal 2 maps an easier process. It has a plan there too, it comes in the form of a simplified level editor [...] a Photoshop for test chambers".[2]

The "Puzzle Creator" does not appear to have a single official name; Valve published a blog post on the October 27, 2011 referring to the editor as the "Puzzle Creator"[3], later referred to it on the blog post of April 27, 2012 as "Puzzle Maker"[4] and simply calling it "Editor" in-game.

Interface

The Puzzle Creator features a stylised representation of the test chamber being worked on; featuring a simplified, bright, and flat color palette, and models and textures lack the level of detail that they would have in-game.

  • Drag the boundary edge of a selection to move the highlighted surfaces.
  • Press and drag the background to rotate your camera view.

Early intermediate

  • Use the adjustment gizmo that appears when you click an item to reposition it on its surface.
  • Double click a surface to automatically expand the selection around all adjacent coplanar surfaces.
  • Block-select surfaces on different planes to select a volume.
  • Look for hotkey shortcuts along the right side of menus.

  • Use Arrow keys to nudge the selection.
  • Shift+arrow keys moves the carat in floor space.

Puzzlecraft tips (unused)

  • Keep goals clear: The puzzle exit should always be visible upon entry.
  • Keep puzzles simple. Players should be able to keep the solution in their head.
  • Keep puzzles transparent. Players should always see the effect of pressing buttons. Avoid putting things in separate rooms.
  • Keep puzzles about the cerebral challenge, not the execution: Puzzles should be easy to solve once players know the solution.
  • If you want your puzzle to be broadly played and enjoyed, don't make players rely on precise timing or 'ninja' FPS skills.
  • Twitchy puzzles that require precise timing are less fun for most players. Expect a smaller audience.
  • Maintain a sense of progression: Split up large puzzles into a series of smaller experiences.
  • Maintain a sense of progression: Avoid puzzles that force the player to revisit the same area again and again.
  • Puzzles are a contest between author and player where the player is ALWAYS expected to win in the end.
  • Good puzzles are not so tricky to be frustrating, but just tricky enough to make players feel smart when they solve it.
  • Keep it simple: Fewer puzzle elements arranged in a clear, strong way are better than many elements organized in a tangled knot.
  • Playtest early and often to know what parts your audience finds too easy or too hard.
  • Keep t-beams away from buttons where they can accidentally lift placed buttons or players.
  • Avoid lasers that are always in the players movement path: they can get annoying really fast.
  • It's okay to have more than one way to solve a puzzle, just be aware that the alternatives exist and that they don't ruin the puzzle.
  • When you add another mechanic to your puzzle, you're increasing complexity -- make sure each added mechanic justifies its existence by contributing something interesting to the puzzle.
  • Find a fun central concept for the puzzle and design back from there.
  • Be careful not to put critical elements on the ceiling. Players rarely look up (or down) unless guided to.
  • There should be a twist in every map. Players get more enjoyment when they figure the twist than when they actually solve the puzzle. The ideal case builds a lot of suspense. 'Whoa! I think this might work' ... [tries crazy idea] ... 'That's awesome! I can't believe I did that!'
  • Avoid straightforward puzzles. They are boring.
  • Players can't judge how far they will fling - try to avoid making a puzzle with multiple options for a fling where players need to choose the same one.
  • Don't make a space that allows for an infini-fling unless it is part of the puzzle. When players are stumped they will frequently try this mechanic. It's also a complicated maneuver so it's possible to fail for a long time before you realize that it's not how to solve the puzzle.
  • Avoid creating linear puzzles in linear spaces.
  • Stick to using puzzle mechanics already defined in Portal 2. Most players don't appreciate idiosyncratic behavior.
  • Play along with users' expectations of how puzzle items function. Defying their expectations loses their trust in how anything will function.
  • Buttons should only have a single output. Multiple outputs can be confusing.
  • Never, ever let the player get into an un-winnable state.
  • Don't allow cubes to get into places where the player cannot retrieve them.
  • Avoid using floor-portal orientations as a puzzle mechanic, as most players are unaware portals even have an orientation.
  • People's eyes are drawn towards brighter areas. Use lighting to direct player attention.
  • Use strip light array, lasers, and other linear features to direct player view along a line.
  • Avoid "chambers within chambers" where players can't see the consequences of their actions on the puzzle state.
  • Testers want to help you improve your map. Listen to their feedback carefullly and always remember to thank them for their time.

Limitations

As the puzzle creator is designed for ease of use, certain limitations apply. These limitations can be overcome by exporting the map to Hammer (see Related Commands).

  • There is a limit of 1750 entities in a single chamber, as opposed to 2048 in Hammer maps. Items consist of multiple entities, meaning the actual number of placeable items is much lower than this.
  • The editor is block based, meaning that angles and smaller geometry cannot be achieved without the use of custom items such as the BEE2's partial blocks.
  • Chambers are isolated, so sequences of chambers cannot be published as one map using the Puzzle Creator alone.
  • Some item placements are disallowed, such as items placed in midair or inside of other items. While somewhat standard for in-game level editors, no such placement rules exist in Hammer.

Unused content

The following have been found in the game files:

  • Puzzle Creator faithplate 128.png Large Aerial Faith Plate
  • 'Push out' panel
  • A radial menu with voting criteria for a map, including "confused" and "stuck".
  • Various "upgrade" badge textures.
  • Puzzle Creator crusher.png Crusher
  • Fixed portal door.png Autoportal
  • Puzzle Creator panel door.png A Glass panel
  • 4x1 observation room
  • Shadows, enabled with the puzzlemaker_shadows command. They are somewhat buggy, and don't accurately represent the actual lighting in the chamber.
  • A "budget bar", enabled with the puzzlemaker_enable_budget_bar command. This bar will fill up as objects are added to the chamber. When exceeded, the editor will not allow the chamber to be built, using the "build failed" message normally only seen when there are placement errors in the map. The final editor simply relies on the compiler to throw an error when over engine limits, instead of implementing an arbitrary system.

Modifications

Modifications are addons that add custom content to the Puzzle Maker.

BEEmod

BEEmod is a well-known Puzzlemaker mod which adds additional content to the editor. The latest version of the mod is version 2.4, which uses a standalone app to configure the item palette and other options not available within the Puzzle Creator itself. Some of BEE2.4's features include additional items such as High Energy Pellets and Autoportals, styles such as Portal 1 and Overgrown, and a large selection of music from various Portal games and mods. BEE2.4 can be downloaded from its GitHub page.
