|
||||
|
||||
Used to control non-component blocks, such as vanilla blocks or blocks from other mods.
|
||||
|
||||
This block allows interfacing with all kinds of blocks, as long as a driver is made available to OpenComputers. For example, OpenComputers comes with such drivers for the vanilla [[Command Block|Component/CommandBlock]] and [[Note Block|Component/NoteBlock]], as well as one for [[Redstone in Motion Carriage Controllers|Component/Carriage]].
|
||||
|
||||
If you're a modder it's pretty easy to write a driver, you just have to implement the corresponding interface from the API and register it with OpenComputers in the init phase. Have a look at the implementation of the built-in drivers for in-depth reference, if you find the documentation is insufficient.
|
||||
|
||||
The Adapter block also serves as a ComputerCraft peripheral, providing an interface imitating that of ComputerCraft's (wired) modems. It will forward network messages sent from ComputerCraft to the OpenComputers side, which can be received if a [[Network Card|Items#network-card]] is installed. It will also OpenComputers' network messages and push a corresponding signal in CC computers attached to the adapter. Note that network messages in OpenComputers do not require a "response port" like ComputerCraft does. If the first argument for the network message is a number, it will be interpreted as the response port to tell ComputerCraft receivers, otherwise the response port will be set to `-1`.

A cheap way of connecting blocks. As described [[on the start page|Home#connectivity]], most blocks in OpenComputers will serve as "connectors", i.e. components will automatically be available to any computers the are indirectly connected to. A few exceptions are the keyboard, which only connects to its screen, the [[Router|Blocks#router]] and the [[Power Distributor|Blocks#power-distributor]] blocks, which explicitly should not connect different networks they are adjacent to. Cables are the least expensive way of building such connections over longer distances. For example, if you wish to have your actual computer in a safe place, and the screen somewhere more visible, you may wish to connect the screen to your computer using cables. Instead of... capacitors. Or more screens.

Stores energy for later use. Can be filled and emptied very quickly. Note that some blocks have a small, internal storage capacity, to allow getting started quickly with a small setup (currently: [[computer cases|Blocks#basic-case]] and [[Power Converters|Blocks#power-converter]]). This means you will have to keep supplying power almost non-stop, to avoid computers shutting down due to power loss. To increase the time a network can continue to function without new power being injected into it you can build capacitors to increase the networks' energy storage capacity.
|
||||
|
||||
You'll also want to have some capacitors ready to allow charging robots at a reasonable pace without bringing down all other components in your network, once you get some. Otherwise they'll just suck your network dry.

The Computer Case is the basic building block for computers and houses the computer's extension cards, RAM and hard disks.

|
||||

||||
From left to right: Card slots/RAM slots/HDD slots.
|

For most use cases a basic case will be quite adequate. When you want to run more complex applications or control multiple screens you may need to upgrade to a higher tier case, though.

@ -46,46 +58,54 @@ Charger

|

Transfers energy from capacitors into adjacent robots. The transfer rate depends on the incoming redstone signal, where no signal means don't charge robots, and maximum strength means charge at full speed.
|
||||
|
||||
You'll need one of these to get your robots running. There is the [[generator upgrade|Items#generator-upgrade]], but you can only put fuel into the generator via the API, meaning you have to get *some* energy into your robot some other way, first. And that way is the Charger block.

Disk Drive

Allows reading and writing [[floppies|Items#floppy-disk]]. ComputerCraft floppies are also supported.
|
||||
|
||||
The main use of Floppies - except being cheaper than hard drives - is to get data onto robots, since they cannot connect to external components, and only have a component slot for floppies, but not for hard drives. If you have the materials, you can build a tier three case, which has a built-in disk drive. Until then, this block is your new best friend.
|

Keyboard

Can be attached to [[screens|Blocks#basic-screen]] to allow typing on them. Note that keyboards can *only* be attached screens. If the screen they are attached to is broken, they will fall off.
|
||||
|
||||
Note that a screen block for itself is just that. A screen. Displaying stuff. Once you attach a keyboard to it, a GUI will open when you right-click/activate it, allowing text input. Note that tier two and three screens allow "clicking" them in the world directly (by right-clicking/activating them), i.e. a "click" signal will be generated. They're touch-screens, so to speak. *This only works if they have no keyboard*.
|
||||
|
||||
Power Converter
|
||||
-----------------
|
||||
|
||||
|
||||
Converts power from other mods to the internal energy type.
|
||||
Default conversion rates:
|
||||
- BuildCraft MJ: 1:5.
|
||||
- IndustrialCraft² EU: 1:2.
|
||||
- Universal Electricity Joules: 1:5.
|
||||
The default conversion rates are:
|
||||
- BuildCraft MJ: 1:1.
|
||||
- IndustrialCraft² EU: 4:1.
|
||||
- Thermal Expansion RF: 10:1
|
||||
- Universal Electricity Joules: 1:1.
|
||||
|
||||
Since there is no way to generate the mods internal energy directly at this point you'll definitely need one of these. Well, the exception is the generator upgrade for robots, but that energy can only be used by the robot with the upgrade.
|
||||
|
||||
Power Distributor
|
||||
-----------------
|
||||
|
||||
|
||||
Distributes energy inside the network. You will need one of these per network. Adding more than one has no effect.
|
||||
Distributes energy between different networks. This can be useful for powering multiple sub-networks that should not connect to each other. For example, you'll usually want to try and keep different computers in different networks - unless you have a startup script on each computer that manually assigns the primary components. Otherwise you'll frequently end up with the computers binding the wrong screen and/or keyboard on startup, for example, or even multiple computer binding to the same screen.

Unlike computers, robots can move around and interact with the world much like a player can. They can **not** interact with external components, however! If you need to communicate with a computer or other robots, use a [[Wireless Network Card|Items#wireless-network-card]] or create some low-level protocol using redstone signals via a [[Redstone Card|Items#redstone-card]].

Allows connecting different networks to each other. Only network messages will be passed along, components will not be visible through this. Use this to separate networks while still allowing communication using Network Cards. The reasoning is the same as for the [[Power Distributor|Blocks#power-distributor]] not connecting its adjacent networks: you may often wish to keep your sub-networks separate. This allows computers in different sub-networks to communicate without having to go all out and use wireless networks.

Screens allow computers to display text, by binding them on a graphics card and then changing their text buffer. Think of these screens more like... chalk boards. You don't have to send the data to display each "frame", instead you set something to display, and the screen will continue displaying it until it's told to display something else. There are a few scenarios where a screen's buffer will be cleared, though: when they are merged into a multi-block screen, and when they are bound by a graphics card.
|
||||
|
||||
Note that screens of all tiers can be controlled by graphics cards of all tiers. However, the minimum capabilities of each combination apply. For example, when using an advanced screen via a basic graphics card, the maximum resolution and color depth will be limited by that of the graphics card.
