''Space Engineers'' is a voxel-based sandbox game set in space and on planets. It is being developed and published by Czech Republic developer Keen Software House. Since 2013, it has been available on Steam as an early access game. While still in active development, ''Space Engineers'' has already sold one million units.〔(【引用サイトリンク】title=Indie of The Year 2013 feature )〕〔 In May 2015, the game's source code was made available to the community for easier modding.〔〔 ==Gameplay== Gameplay of ''Space Engineers'' begins with the player selecting or joining a world with specific settings, such as the number of asteroids and the available starting equipment. When creating or editing a world, several advanced options are available to change how the player will interact with the world, and how the worlds will appear. This includes changing the speed with which several tools and machines will work, and the size of the player's inventory. While loading a world, a screen is visible for a while where one of many quotations concerning space, science, and engineering is visible in the center of the screen. There is a collection of quotes from scientists such as Isaac Newton, Galileo Galilei, Albert Einstein, as well as from Arthur C. Clarke's three laws. Once in-game, the player is given control of a single astronaut, which is referred to as a Space Engineer. The player can then build a station, large ship, or small ship. Construction begins by choosing one of the three options and placing a landing gear, or in the case of a station, a light armor block, which is used as the starting point for the rest of the structure. Blocks may be structural, functional, interactive, or aesthetic, and may fall into more than one category. Blocks also take up varying amounts of space. In addition to placing blocks, the player can also use tools and weapons. Most blocks can be damaged and deformed through collisions or by weapon impacts.〔(【引用サイトリンク】title=Space Engineers is a physics sandbox about creation and destruction )〕〔(【引用サイトリンク】title=Hands On With Space Engineers - Rock, Paper, Shotgun )〕 Some blocks have attached keypads, which can be used to view and manipulate the status of other specific blocks attached to the structure. To be functionally connected however, and to transport materials, conveyors must be used to connect the desired machines. Functional blocks require power, which can be provided by solar panels or nuclear reactors attached to the same structure. While reactors must be supplied with uranium, and produce large amounts of power while active, solar panels will continually produce a low output of power when there is line-of-sight to the sun. Once being produced, power is automatically distributed throughout the entire structure. Three types of structures are available: small ships, large ships, and stations. The size, resource requirements, and availability of blocks depends on the type of structure they are attached to. Small ships do not allow assemblers or refineries, whereas large ships cannot use gatling guns, instead using the AI-controlled gatling or missile turret variations. Blocks attached to a small ship are considerably smaller and require fewer resources than those attached to large ships or stations (for example, light armor requires 25 steel plates on a station, but only 1 on a small ship). Stations use the same blocks as large ships and can be converted into large ships using a control terminal; however, they are immobile and can instead be physically anchored to an asteroid. Ships can be deliberately moved and rotated by a player as long as they are powered and have at least one gyroscope, thruster, and cockpit. To be able to move in any direction and then be able to stop effectively via inertia dampeners, thrusters must be placed on the structure facing up, down, forward, backward, left, and right. More gyroscopes on a ship will increase the ships ability to rotate in space, but in order for the inertial dampeners to be more effective, more thrusters must be added in each direction in which dampening is required. Astronauts floating in space are able to move forward, backward, upwards, downwards, left, or right without restriction by using a jetpack. They are also able to rotate clockwise or counterclockwise. Astronauts and structures can also enable or disable inertial dampeners, which automatically attempt to reduce speed to zero when force is not being applied, and the required thrusters are installed. While on a structure or asteroid within range of a gravity generator, if the player's jetpack is disabled, movement is restricted to a plane perpendicular to the direction of the net gravity field(s). Vertical viewing angle is also restricted between -90 and 90 degrees, as in most first person shooters. If the player falls off a structure while within a gravity field, the player will fall into space until out of range of the gravity generator, at which point the player's jetpack will automatically enable itself. However, ships and structures are unaffected by gravity generators unless equipped with the Artificial Mass block. Players and the Artificial Mass block can accelerate past the maximum thruster speed of 154.7 meters/second using multiple gravity generators. Several types of cargo ships can spawn randomly and fly through the world, which can be hijacked by the player or harvested for components. Some of these cargo ships are booby trapped to explode when the player attempts to commandeer them, and are sometimes armed with hostile gatling turrets. To prevent booby-trap explosion, players must either avoid thrusting backwards, or find and disable any forward-facing thrusters in the ship aimed directly at warheads. Some cargo ships can also be defended by gatling or missile turrets, which can either be directly destroyed or disabled by slowly approaching the ship from a distance to avoid detection and disabling the turrets through a control panel. All place-able objects can also be colored prior to placement using a slider-based GUI. The player can manipulate the hue, saturation, and value of the color to produce a very large spectrum of colors. There are 14 slots where new colors can be saved for later use within the same world. Colors can be changed after blocks have been placed, using the middle mouse button while hovering over a block on the "Color Picker" GUI. Asteroids are currently fixed in space and do not move, however, rock that has been mined is subject to gravity from gravity generators and will travel in space similarly to players or ships. Asteroids currently do not have gravity associated with them, and they come in several basic forms including spherical, torus, and rod-shaped, and other variations or combinations of these shapes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Space Engineers」の詳細全文を読む スポンサード リンク
