'''Research''' is used to unlock [[technologies]], offering new recipes and bonuses. Research is performed by [[lab|labs]] consuming different types of [[science pack|science packs]].


== Basics ==
== Mechanics ==


* Research is performed in [[Lab]]s.
In singleplayer games, only one technology can be researched at a time, the same is true for every [[Multiplayer#PvP|force]] (team of players) in a multiplayer game. In multiplayer games with multiple forces, each force has its own technology tree and research status, so different forces can research independently in [[Multiplayer#PvP|PvP]] games.
* Every technology has a certain amount of units that are needed for it to be researched, the logistics 1 technology in the example requires 20 units.
* Every unit requires a certain combination of science packs, these have to be created and transported into the lab before it can start the research.
* When the laboratory has all the needed ingredients, it starts researching one unit, the time to research the unit varies from technology to technology.
* The more laboratories are researching at the same time, the shorter time it takes to get all the units required.


The technology to be researched is selected from the technology screen, opened by pressing {{Keybinding|T}} ({{Keybinding|ZL|-}} on [[Nintendo Switch version|Nintendo Switch]]). The currently active research can be changed at any time from the technology screen; if another research is in progress, that progress will be saved. Multiple technologies can be partially researched like this at any one time.


[[File:Techlist.png]]
Research progress for a technology is divided into ''units''. Each unit has a time and a science pack cost. When research is in progress, labs with the required amount of science packs for one unit will consume the amount and contribute towards research progress.


[[File:res.png]] Example of research
[[File:res.png|frame|The progress bar shown in the top right corner of the screen when research is in progress]]


The time ''T'' it will take to research a particular technology is given by:
*<code>T = (T[0] × P) ÷ (L × S)</code> seconds,
where:
*'''''T[0]''''' is the time cost per unit (as shown in Research screen)
*'''''P''''' is the price of the research, in units (as shown in Research screen)
*'''''L''''' is the number of labs used
*'''''S''''' is lab speed, which is given by:
**<code>(1 + B[r]) × (1 + M[r])</code>, where
**'''''B[r]''''' is the total research speed modifier from [[Lab research speed (research)|lab research speed]] research, expressed as a decimal (% value divided by 100); and
**'''''M[r]''''' is the sum of all module effects (Speed modules with <code>+</code> sign, Productivity modules with <code>-</code> sign), expressed as a decimal
''Note that ''P'' represents the research price '''in units''', not in individual science packs summed across all their types. For example, a research that costs 100 [[automation science pack]]s and 100 [[logistic science pack]]s, grouped into 100 units of 1 each of automation and logistic science packs, would have a ''P'' of 100, ''not'' 200.''
Unlike most bonus effects, the lab research speed bonus gained from research is ''multiplicative'' with module speed effects, not additive. However, different module effects (Speed vs. Productivity, beacon vs. in-lab) are additive with each other.


=== Automation ===
=== Automation ===
[[File:5_5_Labs_R_G_packs.png|400px|thumb|right|A simple lab setup using [[automation science pack]]s and [[logistic science pack]]s, [[belt transport system|belts]], and [[inserters]]]]
Crafting science packs by hand is not feasible, mainly because of the amount of resources and time needed to craft them. Some science packs also require ingredients that cannot be handcrafted, such as [[oil processing|oil products]]. Science pack production automation is the primary incentive for factory development throughout the game.
The insertion of science packs into labs may be automated using [[inserters]] and [[transport belt]]s, as shown to the right, or using [[robots]] and the [[logistic network]].
Note that inserters can take science packs from labs and hand them to other labs, making a lab chain a feasible solution. Other options include using 3 belts (before space science packs are needed), or a [[Glossary#S|sushi belt]].
=== Research queue ===
[[File:Research_Screen_Queue.png|400px|thumb|right|The technology screen with some technologies queued.]]
The research queue allows players to automatically research more technologies after a research finishes. The research queue is by default unlocked when the first rocket is launched. Alternatively it can be unlocked in the map generation settings in the 'advanced' category, or via `/enable-research-queue` console command.
Once the research queue is enabled, a technology can be added to the queue by pressing the "Start Research" button when it is selected. Double clicking (Double-pressing {{Keybinding|Y}} or {{Keybinding|A}} on [[Nintendo Switch version|Nintendo Switch]]) or using {{Keybinding|shift|lmb}} ({{Keybinding|ZR|A}} on [[Nintendo Switch version|Nintendo Switch]]) on any research in the tree or the list on the left will also add it to the queue. This is particularly useful to queue prerequisites without focusing them in the technology tree.
Technologies in the queue are displayed in the upper left corner of the interface. If a technology is added to the queue, the technologies that depend on it may become available to be added to the queue as well and those technologies are displayed in orange. For example adding the [[Logistics_(research)|logistics]] and [[Logistic_science_pack_(research)|logistic science pack]] technologies to the queue allows the technology [[Logistics_2_(research)|logistics 2]] to be queued.


For the new player, the basic red research pack will be the first bigger item they try crafting by hand only to realise how slow it is. The idea to automate production of the red science packs (and their insertion into the labs) will occur and grow to automate the green and blue too.  
To remove a technology from the queue, the technology's image must be hovered in the queue display in the upper left corner and the red button that appears must be pressed.


This process forms a good part of the early/mid game to establish a reasonable progression speed through the tech tree.

The technology screen

Research is used to unlock technologies, offering new recipes and bonuses. Research is performed by labs consuming different types of science packs.

Mechanics

In singleplayer games, only one technology can be researched at a time, the same is true for every force (team of players) in a multiplayer game. In multiplayer games with multiple forces, each force has its own technology tree and research status, so different forces can research independently in PvP games.

The technology to be researched is selected from the technology screen, opened by pressing T (ZL + - on Nintendo Switch). The currently active research can be changed at any time from the technology screen; if another research is in progress, that progress will be saved. Multiple technologies can be partially researched like this at any one time.

Research progress for a technology is divided into units. Each unit has a time and a science pack cost. When research is in progress, labs with the required amount of science packs for one unit will consume the amount and contribute towards research progress.

The progress bar shown in the top right corner of the screen when research is in progress

The time T it will take to research a particular technology is given by:

  • T = (T[0] × P) ÷ (L × S) seconds,

where:

  • T[0] is the time cost per unit (as shown in Research screen)
  • P is the price of the research, in units (as shown in Research screen)
  • L is the number of labs used
  • S is lab speed, which is given by:
    • (1 + B[r]) × (1 + M[r]), where
    • B[r] is the total research speed modifier from lab research speed research, expressed as a decimal (% value divided by 100); and
    • M[r] is the sum of all module effects (Speed modules with + sign, Productivity modules with - sign), expressed as a decimal

Note that P represents the research price in units, not in individual science packs summed across all their types. For example, a research that costs 100 automation science packs and 100 logistic science packs, grouped into 100 units of 1 each of automation and logistic science packs, would have a P of 100, not 200.

Unlike most bonus effects, the lab research speed bonus gained from research is multiplicative with module speed effects, not additive. However, different module effects (Speed vs. Productivity, beacon vs. in-lab) are additive with each other.

Automation

A simple lab setup using automation science packs and logistic science packs, belts, and inserters

Crafting science packs by hand is not feasible, mainly because of the amount of resources and time needed to craft them. Some science packs also require ingredients that cannot be handcrafted, such as oil products. Science pack production automation is the primary incentive for factory development throughout the game.

The insertion of science packs into labs may be automated using inserters and transport belts, as shown to the right, or using robots and the logistic network.

Note that inserters can take science packs from labs and hand them to other labs, making a lab chain a feasible solution. Other options include using 3 belts (before space science packs are needed), or a sushi belt.

Research queue

The technology screen with some technologies queued.

The research queue allows players to automatically research more technologies after a research finishes. The research queue is by default unlocked when the first rocket is launched. Alternatively it can be unlocked in the map generation settings in the 'advanced' category, or via `/enable-research-queue` console command.

Once the research queue is enabled, a technology can be added to the queue by pressing the "Start Research" button when it is selected. Double clicking (Double-pressing Y or A on Nintendo Switch) or using SHIFT + Left mouse button (ZR + A on Nintendo Switch) on any research in the tree or the list on the left will also add it to the queue. This is particularly useful to queue prerequisites without focusing them in the technology tree.

Technologies in the queue are displayed in the upper left corner of the interface. If a technology is added to the queue, the technologies that depend on it may become available to be added to the queue as well and those technologies are displayed in orange. For example adding the logistics and logistic science pack technologies to the queue allows the technology logistics 2 to be queued.

To remove a technology from the queue, the technology's image must be hovered in the queue display in the upper left corner and the red button that appears must be pressed.
