Ru/Behind the Scenes (Portal 2)

Фабрика

Тема фабрики является Portal 2-версией "закулисья" из Portal. При создании карты на данную тему помните, что это вторая новейшая часть Aperture, поэтому стройте соответствующую обстановку. Кроме того, пробуйте смешивать уровни с темой тестовых камер в различных интересных комбинациях.

Пневматические трубы, турели и мостики являются здесь ключевыми элементами, так же как и 3D-скайбокс, бездонные ямы и туман, чтобы создать ощущение больших размеров. Здесь стены сделаны из бетона, металла или пластика, реже встречается плиточное покрытие. Звуковой ландшафт насыщенный, на промышленную тему, здесь особенно слышно, как свистят пневматические трубы.

Эта тема также используется в конце каждого тренировочного теста в кооперативе.

Переходы между уровнями происходят в узких коридорах между двумя тяжелыми автоматическими дверями.

Детальное описание

В этой теме вы всюду встретите трубы, транспортирующие различные предметы в неизвестные части огромного комплекса.

This theme serves really only for plot advancement, so the scope for puzzles is somewhat limited here. Sure, there's the old 'portal over to that wall behind me' to traverse long distances and stretch out dialogue, but making actual puzzles out of this theme without making it feel contrived is kind of difficult. You'll see it done more successfully in co-op maps usually, due to the fact that the plot isn't quite as important and Valve tried to make the theme a puzzle rather than to leave an impact on the player.
The exception to this is if you're making a full-blown mod, maybe even with a story; as aforementioned, these can make nice interludes, and the sheer multitude of destruction sequences available for the catwalks are brilliant for action scenes. Due to the nature of this theme, the huge vistas along with numerous dynamic elements it is recommended for users with advanced knowledge of hammer.

The vast proportions of Aperture Laboratories allows a lot of free space to exist between test chambers and other rooms used for various purposes. In these in-between areas a lot of 'behind the scenes' work is done, like building and testing of test elements. Because of this the theme is more to immerse the player than to be a good puzzle environment, however, using the various 'test elements in-testing-state' as functioning test elements could make it a more interactive puzzle. Most puzzles seen in this theme tend to revolve around momentum, and they do tend to work best in co-op. However, if you have an idea for a puzzle that involves moving test elements, conveyor tracks or exceptionally big momentum puzzles, try going with this theme.

Something that is important to keep in mind when building tests for this theme is that it should look as if it was not designed to be a test. There shouldn't be a solution, as this is not a test, only a way to advance. Keeping the 'tests' looking realistic is to make the player break the rules in these parts, like walking on the reverse direction of a conveyor belt, breaking tubes that deliver test elements to other parts of the facility, etc.

Наиболее заметные детали

Aperture Laboratories is known to solve their problems in the most ridiculous way possible, take the Pneumatic Diversity Vents for example, seen transporting numerous test elements and garbage from one place to another.

Humans, on the other hand, use catwalks as their form of transportation, and these should be connect to every door, button stand or anywhere maintenance might be needed, like around vents and 'quality control' stations. If you don't want the player to explore an area, placing destroyed catwalks or locked doors/gates would be a good way to do this without it looking unrealistic.
All other robotic personnel use management rails, which they cannot readily be detached from.

Пневматические трубы

The Pneumatic Diversity Vents are used extensively throughout this theme, as a mean to give further background of the facility and how it is constructed. Serving no other purpose other than decoration their use is very limited; however clever use of them had been seen in the official campaign, such as:

• Long plot advancing 'tube ride' sequences
• Transporting test elements
• Destroyed to deliver gel

The tubes are not aligned to the grid; they're bent in every direction, reaching every building in the facility; but don't be alarmed, their construction is exceedingly simple. Before making a pipe remember that you don't need it to make sense, if the tube goes behind a building where the player can't see it there is no need to attach it to anything, just finish it there. Also, when making the tubes notice there are four beams surrounding the tube, make sure they are all aligned with the ones of the next model (that means only 90° Pitch Yaw Roll values).
Now let's start, first create the basic shape you want your vent to have; for example, a long straight line that has a 'T junction' at the end. Now group all the models you used to create you basic shape and rotate them freely so they would look purposeless. That's about it; with time you'd improve upon it.

Путешествие по трубам

In the official campaign there is a part where the player and Wheatley are sucked by a vent and sent through the pipe system to GLaDOS's chamber. This was done by attaching a point_viewcontrol to a 1x1x1 model which is animated to be flying through a very specific set of pipes. When you are creating your own maps, this is not necessarily required as the point_viewcontrol can follow the path used to navigate the tubes.

Примечание:The process may be somewhat lengthy, depending on the length and complexity of the tubes you want the player to "ride" through.

Создание транспортирующей трубы

Нужно сделать: Add pictures to clarify this process and expand this section.

Примечание:You will want to make sure you have the route for your tubes planned out very carefully as it can be rather time-consuming to rearrange things if the tubes end up misaligned.

Создание пути

These instructions assume you have a room to place the tubes in and connect the tubes to.

1. Place the tubes you want the player to pass through. Use a mixture of straight tubes and turns to make it interesting.
2. Place a path_corner at roughly the height of the player's head. Name it tube_path1.
   Примечание:This makes the transition to the point_viewcontrol a smooth one.
3. Copy the path_corner and move the copy to the end of the first tube section. If the first path_corners doesn't link to the new one, enter the name of the new one into the Next stop target field in the properties of the path_corner.
   Примечание:You can actually move the copy to the first turn in the tube path if you prefer as it means fewer objects in your level. The number of path_corners you use determines how smooth the ride will be.
4. When you reach a corner in the tube path, place a copy of the path_corner near the end of the turn.
5. Make and move another copy of path_corner into place slightly further into the turn.
6. Move the next copy into the turn a few units, ensuring the path_corner is not touching the sides of the tube.
7. Make and move another copy of the path_corner into the next segment.
8. Repeat steps 2-7 above until you reach the end of your tube path.

Как заставить путь работать

This tutorial has the most comprehensive and easiest to follow steps to making the point_viewcontrol follow the path created inside the tube path: http://halfwit-2.com/?page=tutorials&id=120. I would suggest going there to get help setting up the path to follow inside the tubes.

Транспортировка тестовых элементов

In some of the maps in the official campaign these vents were used to transport bombs at the press of a button. This is a good way to interactively transport elements in the behind the scenes sections of the game, as normal cube droppers don't fit this theme.

A good puzzle introduced in the cooperative campaign had a vent that sends one cube out of it at a press of a button, one player had to press the button, while the other had to fling to catch it in time.
This map is named mp_coop_fan.

Most test elements in the vents are animated props, but since these are only good for very specific arrangement of the tubes, it is recommended to make prop_physic be transported through the tube with the help of trigger_push brushes that will be placed in the tubes, like done in the Pneumatic Diversity Vent test element.

Раздача геля

In some parts of the behind the scenes environment there are vents that transport gels from the Old Aperture parts to the newer parts of the facility. Some environments may require use of these gels, but like stated above, test elements are not supposed to be used in these parts, therefore another way must be found to retrieve the gel. Breaking the tube is one way of achieving this.

Use a particle effect and place it's first control point somewhere in the map close to the info_particle_system from which it originates from. You could still use it as a straight particle if the control point is directly in front of the particle_system.

Также имеются следующие эффекты частиц:

• blob_curve_blue - для отталкивающего геля
• blob_curve_orange - для ускоряющего геля
• blob_curve - для преобразующего геля

Опоры и перекрытия

Это основные компоненты системы труб. * означает, что они должны быть 'не сплошными', т.е. чтобы объекты могли проходить сквозь них.

• models/props_bts/vactube_128_straight.mdl
• models/props_bts/vactube_90deg_02.mdl
• models/props_bts/vactube_90deg_03.mdl

Направляющие рельсы

Направляющие рельсы используются как основной способ передвижения модулей персональности, управляющих комплексом. При подключении к своему рельсу они прикрепляются к двум динамическим опорам; одна держит модуль, а другая соединяет его с рельсом:

• models/npcs/personality_sphere/management_rail_ball.mdl
• models/npcs/personality_sphere/management_rail_stick.mdl

Рельс состоит либо из набора опор (models/props_bts/rail_horizontal...mdl), либо из набора брашей func_detail.

Различные советы

В этой теме следует использовать следующие элементы:

• Большие металлические опоры
• Длинные мостики
• Направляющие рельсы
• Пневматические трубы
• Конвейерные ленты
• Большие пространства
• Тяжелые двери
• Измельчители

There are a number of models designed for this section of the game, in the form of cables, vents and, of course, catwalks, and I recommend you use these. They don't have to be anything captivating or dynamic, but a wall with cables makes a lot more sense than one without; there are, by the way, instances for detailed cable Walls and such things. Also, it is very much recommend you use some of the behind the scenes overlays, such as numbers, 'Turret Manufacturing', etc.
