LArRE Dock (Hydroponics)

DootDoot: Adding further tested scenarios for reading Tray/Device Fertilizer slot

== Slot Variables ==

This LArRE has a special slot 255 which can sample slot variables from a structure (hydroponics tray/device or import/export chute) under the current station. While some slot variables are documented on LArRE's in-game stationpedia page, the slot variables for the adjacent device are only documented on the device's page. Not that while the [[Hydroponics Tray]] does not have a data connection, the LArRE slot 255 can sample the same Slot Variables from the tray as are documented for the [[Hydroponics Device]].

Fertilizing is dynamically handled using just <code>Activate</code> while holding [[Fertilizer]], but it is unclear how the slot variables for the Fertilizer slot on Tray/Device can be accessed:
* <code>TargetSlotIndex</code> Logic Type only allows <code>Read</code>
* [[LArRE Dock (Cargo)]] is unable to read Tray/Device slots using the proxy slot; reading <code>Occupied</code> results in <code>IncorrectLogicType</code>

== Plant growth states ==

This LArRE has a special slot 255 which can sample slot variables from a structure (hydroponics tray/device or import/export chute) under the current station. When designing a MIPS script to operate LArRE, you must understand how those slot variables change as the crops grow.

{| class="wikitable"
|-
! Slot Variable !! empty !! early !! crops grown !! seed grown !! seed harvested & crops available !! dead
|-
| Occupied|| 0 || 1|| 1|| 1|| 1|| 1

|-
| Mature || 0 || 0 || 1 || 1 || 1 || 0
|-
| Seeding || 0 || -1 || -1 || 1 || 0 || -1
|}

Most crops are consumed by harvesting and must be replanted after the last crop is picked by the LArRE. They transition from growth 6 to 0 when the last crop is harvested.

There are some crops that are "perennial", where when the last crop is harvested, a plant remains to grow a new set of fruit and seed. These crops transition from growth 6 to 3 and seeding from 1 to 0 to -1.

{| class="wikitable"
|-
! Plant !! Fully grown (fruited) !! After harvesting
|-
| [[Switch Grass]] || Growth: 7 || Growth: 5
|}

Crops that are under stress (temperature, light, or water) for long enough start gaining damage. If the environment is not fixed before the damage reaches 1.0 the crop is dead and must be cleared from the tray, and a replacement plant installed.

== Description ==
<blockquote>"The cargo LArRE can take things out of and put things into slots of devices. The dial on the front panel indicates which slot on the device to interact with. The slot variables of the item in the target slot can be read using the Proxy Slot Index (255)

Pressing the activate button while the LArRE arm is at its home dock will move the arm off the main rail. This allows other arms on the same rail to pass by."

'''- Stationpedia'''</blockquote>

== Usage ==
The dock can be connected on both sides to a network of [[Linear Rail|Linear Rails]] to enable LArRE to move horizontally and vertically.

[[Linear Rail#Station|Linear Rail Stations]] must be positioned so that LArRE can stop and interact with the device below. The network can only be linear (i.e. without intersections). Each station (including the dock) is assigned a number. Stations can be assigned a negative number unless the rail connections make a loop back to the dock.

If the network is modified (by removing or adding a rail), LARrE will be teleported to its dock. LARrE is also susceptible to collisions with players and structures. If it is blocked while moving towards its target station, LArRE will stop and flash an error until the path is cleared or the target is changed.

{{Data Network Header}}This LArRE contains an Arm Slot (0) and Target Slot (255). The Arm Slot refers to the item in the LArRE Arm, and the Target Slot refers to the object underneath the Arm when positioned at a [[Linear Rail|Linear Rail Station]].

==Description==
Harvie is designed to assist in automating your farm. Place above a [[Hydroponic Tray]] to automate the planting and harvesting of that tray. Power connects at the top of the unit and there is an import and export slot on either end of the top of the unit to allow [[chutes]] to transport the products. Setting a logistical network with [[circuits]] will be required to function properly. Note: Harvies cannot fertilize crops.

==Quirks ==

If Harvie's input slot is fed by a chute, it will not stack identical items. If there are already 4 Fern Seeds in his input, and a fifth arrives via chute, that fifth will remain in the chute until all 4 have been removed from the input (probably by planting).
