{{Function
|name=turtle.suck
|args=
|returns=[[boolean_(type)|boolean]] true if at least one item was moved into the turtle's inventory; false otherwise.
|api=turtle
|addon=ComputerCraft
|desc=
Moves one or more items from either the ground in front of the turtle, or, from an inventory-enabled block (such as a chest) in front of the turtle.
* If an item is in the square directly in front of the turtle, it picks up one of those items.
* If a chest is in the square directly in front of the turtle, it picks up the items from the first non-empty chest slot, moving from top left to bottom right. The items are moved into the currently selected turtle slot if there is room.
* If the currently selected turtle slot is filled up before all of the items are picked up, the remaining picked up items are put in the next available turtle slot.
* If the currently selected turtle slot is 16 and the next slot is required, it will loop around and try turtle slot 1, and so on.
* As of Minecraft 1.5/ComputerCraft 1.51, turtle.suckUp can be used to pick items out of the output slot of a furnace.

Turtle.drop

Foone: Minecraft 1.5 changed how furnaces work, so some clarification on changes

{{lowercase}}
{{Function
|name=turtle.drop
|args=[<nowiki></nowiki>{{type|int}} count]
|returns={{type|boolean}} true if an item was dropped; false otherwise.
|api=turtle
|addon=ComputerCraft
|desc=Drops all items in the selected slot, or if ''count'' is specified, drops that many items.
If the space in front of the turtle does not contain a chest, the items are dropped into that space.
If the space in front of the turtle contains a chest, the items are dropped into that chest.
The items will be placed in the first available slot, starting at the top left, moving right and then down.

turtle.dropUp and turtle.dropDown are also available, and useful for loading furnaces; dropDown when above the furnace will load the top slot for smelting.

Before Minecraft 1.5/ComputerCraft 1.51, dropUp would load the bottom (fuel) slot for furnaces, since the hopper-related changes, fuel is loaded into the sides, and the output slot is available on the bottom (using [[Turtle.suck|turtle.suckUp]])

Foone: Fixing sonic sensor recipe for 1.5.2.0

[http://www.computercraft.info/forums2/index.php?/topic/5996-144-cc-147-openccsensors/ OpenCCSensors] is a new, open-source, up to date replacement for [[CcSensors|CcSensors (outdated)]], allowing monitoring and gathering information from the Minecraft environment - including players, entities, proximity, world info, IndustrialCraft 2, BuildCraft 2, liquids, inventories - and more!

OpenCCSensors comes with its own API, and automatically installs a new program for you at /ocs/programs/sensorview. sensorview is a handy program for very quickly looking at the information gathered from your sensors.

Foone: Fixing recipe for inventory sensor

[http://www.computercraft.info/forums2/index.php?/topic/5996-144-cc-147-openccsensors/ OpenCCSensors] is a new, open-source, up to date replacement for [[CcSensors|CcSensors (outdated)]], allowing monitoring and gathering information from the Minecraft environment - including players, entities, proximity, world info, IndustrialCraft 2, BuildCraft 2, liquids, inventories - and more!

OpenCCSensors comes with its own API, and automatically installs a new program for you at /ocs/programs/sensorview. sensorview is a handy program for very quickly looking at the information gathered from your sensors.

Foone: Applying card redesigns from 0.1.5

[http://www.computercraft.info/forums2/index.php?/topic/5996-144-cc-147-openccsensors/ OpenCCSensors] is a new, open-source, up to date replacement for [[CcSensors|CcSensors (outdated)]], allowing monitoring and gathering information from the Minecraft environment - including players, entities, proximity, world info, IndustrialCraft 2, BuildCraft 2, liquids, inventories - and more!

OpenCCSensors comes with its own API, and automatically installs a new program for you at /ocs/programs/sensorview. sensorview is a handy program for very quickly looking at the information gathered from your sensors.

* Peripherals can now be controlled remotely over wired networks
* New peripheral API function: getNames()
* New event: “monitor_resize” when the size of a monitor changes
* Except for labelled computers and turtles, ComputerCraft blocks no longer drop items in creative mode
* The pick block function works in creative mode now works for all ComputerCraft blocks
* All blocks and items now use the IDs numbers assigned by FTB by default
* Fixed turtles sometimes placing blocks with incorrect orientations
* Fixed Wireless modems being able to send messages to themselves
* Fixed [[turtle.attack]]() having a very short range
* Various bugfixes
|align=center|1.5

*Redesigned Wireless Modems; they can now send and receive on multiple channels, independent of the computer ID. To use these features, interface with modem peripherals directly. The rednet API still functions as before.
*[[Floppy Disk|Floppy Disks]] can now be dyed with multiple dyes, just like armour.
*The “excavate” program now retains fuel in it’s inventory, so can run unattended.
*[[turtle.place]]() now tries all possible block orientations before failing.

Foone: Quick fix of crafting recipe

{{NeedsWork|The behaviour of Rednet has changed as of 1.5 - please consider updating this page with information. (Please don't add prerelease info!)}}
{{Block
|name=Modem
|image=
|id=???
|damage-value=???
|is-peripheral=Yes
|peripheral-api=Rednet (API)
}}
Modems are blocks which can be used to wirelessly transfer data between [[Computer|computers]] and [[Turtle|turtles]], using the [[Rednet_(API)|Rednet API]].
To place a modem on a side of a computer, right-click to place the modem while sneaking.

It is also possible to turn the modem on and off by typing "rednet.open ( side )" to open and "rednet.close ( side )" to close.

Modems can send messages to other modems located up to 64 meters away, or 16 meters during a thunderstorm.
As of 1.4 Modem range is increased with higher altitudes. If there is no thunderstorm, the range will always be higher than 64, and at max altitude you would have a range of 384 meters.

In 1.4 and 1.41 there is a miscalculation that causes the range to only be 381 meters at max altitude.

|A1=stone |B1=stone |C1=stone
|A2=stone |B2=ender_pearl |C2=stone
|A3=stone |B3=stone |C3=stone
|Output=Modem
}}
== Example ==
* Place 2 computers and add modems to them by clicking the right mouse button while sneaking.
* Access them, and start Lua.
* Once Lua has started, type "[[rednet_(API)|rednet]].[[rednet.open|open]] ("<relative location to modem, e.g. left, right>")" on both computers.
* Check if there exists a connection: a dim, red light should be found on the modem.
* Type on one computer "[[rednet_(API)|rednet]].[[rednet.receive|receive]] (60)". This will make the computer freeze for 60 seconds, or until it has received a signal from the other computers.
* Now, type "[[rednet_(API)|rednet]].[[rednet.broadcast|broadcast]] ('<your message>')" on the other computer. This should send your message to all computers connected.
* Opening the first computer should show the message written on the second computer.

==Modem as a Peripheral==
To use a Modem as a peripheral, you need to either call a method directly using [[peripheral.call]](), or, wrap the modem using the [[Peripheral_(API)|Peripheral API]]. Wrapped modems provide all functions listed in the [[Rednet_(API)|Rednet API]].

For this example, we have a Modem connected to the top of our [[Computer]]:

-- Immediately invoke a method without wrapping
peripheral.call("top", "open")

-- You can also "wrap" the peripheral side to a variable:
local modem = peripheral.wrap("top")
modem.open("top")

[http://www.computercraft.info/forums2/index.php?/topic/5996-144-cc-147-openccsensors/ OpenCCSensors] is a new, open-source, up to date replacement for [[CcSensors|CcSensors (outdated)]], allowing monitoring and gathering information from the Minecraft environment - including players, entities, proximity, world info, IndustrialCraft 2, BuildCraft 2, liquids, inventories - and more!

OpenCCSensors comes with its own API, and automatically installs a new program for you at /ocs/programs/sensorview. sensorview is a handy program for very quickly looking at the information gathered from your sensors.
