Items
This page lists all items OpenComputers adds to the game. Please check the recipes via NEI, since they're still subject to change, and there may even be context-specific recipes at some point in the future (i.e. recipes using BuildCraft, IndustrialCraft² or GregTech specific parts, based on which of these mods are installed).
Component items are items that when installed in a computer case or robot can be interacted with from Lua. See the page on this topic for more information.
Enables robots to use the top left area of their inventory for crafting objects. Items have to be aligned as they would be in a crafting table.
See the component API on how to use it.
Can be used to generate energy from fuel on the go. Burns items to generate energy over time, based on their fuel value.
Note that fuel can only be inserted into the generator via its API, so you'll have to charge your robot up to a certain level using a charger block first.
Per default the generator's efficiency is at 80% of a BuildCraft Stirling Engine, i.e. it consumes the fuel at the same pace a Stirling Engine would, but only outputs 80% of the energy a Stirling Engine would.
Used to change what's displayed on screens. Computers can control the buffer of a bound screen via the GPU's API.
- Maximum resolution: 50x16.
- Maximum color depth: 1.
- Operations/tick: 1/1/4/2/2.
The operations refer to, from left to right: copy, fill, set, setBackground and setForeground. The number indicates the number direct calls that can be made to each of these functions on the graphics card per tick before an indirect call has to be made. See the page on component interaction for more information on direct calls.
Used to change what's displayed on screens. See Basic Graphics Card.
- Maximum resolution: 80x25.
- Maximum color depth: 4.
- Operations/tick: 2/4/8/4/4.
Used to change what's displayed on screens. See Basic Graphics Card.
- Maximum resolution: 160x50.
- Maximum color depth: 8.
- Operations/tick: 4/8/16/8/8.
Allows distant computers connected by other blocks (such as cable) to communicate by sending messages to each other.
See the network card component's API to see how to send and receive messages.
Allows reading and emitting redstone signals around the computer or robot. This uses the same API as the Redstone I/O block.
If the respective mods are also installed, this supports simple and bundled redstone signals for RedLogic and/or MineFactory Reloaded's RedNet.
This is an upgrade to normal network cards that allows wireless sending of network messages in addition to normal ones.
Make sure to set the signal strength or no wireless packet will be sent, but keep in mind that sending wireless messages requires energy (configurable).
Another important feature of the wireless network card is that it allows sending HTTP requests (if enabled in the configuration).
While technically also components, you'll usually interact with components using the filesystem API or a couple of built-in programs (such as ls and mkdir) instead of using their component API directly.
Per default, storage devices get auto-mounted in the /mnt directory, under a directory representing the first couple of letters of their component address. You can mount any storage device at multiple locations using the filesystem API or the mount program.
Small and cheap storage device that can be inserted into disk drives, tier three computer cases and robots.
Hard disk drives (HDDs) come in three tiers, with increasing storage capacity (each tier's capacity is configurable). They can store more data than a simple floppy, but are also more expensive to craft. They can also only be installed in computer cases. They can not be installed in robots.
Used to display information about blocks, such as their address and component name. Also displays the error that caused a computer to crash if it did not shut down normally.
Note that if you hold Ctrl while analyzing a block, that block's address will be copied to your clipboard (if the block has an address, that is).
Memory (RAM) comes in three tiers, with increasing sizes (each tier's size is configurable). Memory isn't really a component, since it does not provide any Lua callbacks, but it can be installed into computer cases to increase the available RAM of the computer, which allows running more complex programs.
There are also a number of items that are exclusively used for crafting. As mentioned above, please consult your local NEI installation for recipes.
