Signs Bot [signs_bot]

A robot controlled by signs.

The bot can only be controlled by signs that are placed in its path. The bot starts running after starting until it encounters a sign. There, the commands are then processed on the sign. The bot can also put himself signs in the way, which he then works off. There is also a sign that can be programmed by the player, which then are processed by the bot.

There are also the following blocks:

Sensors: These can send a signal to an actuator if they are connected to the actuator.
Actuators: These perform an action when they receive a signal from a sensor.

Sensors must be connected (paired) with actuators. This is what the Connection Tool does. Click on both blocks one after the other. A successful pairing is indicated by a ping / pong noise. When pairing, the state of the actuator is important. In the case of the bot box, for example, the states "on" and "off", in the case of the control unit 1,2,3,4, etc. The state of the actuator is saved with the pairing and restored by the signal. For example, the robot can be switched on via a node sensor.

An actuator can receive signals from many sensors. A sensor can only be connected to an actuator. However, if several actuators are to be controlled by one sensor, a signal extender block must be used. This connects to a sensor when it is placed next to the sensor. This extender can then be paired with another actuator.

Sensors are:

Bot Sensor: Sends a signal when the robot passes by
Node Sensor: Sends a signal when it detects a change (tree, cactus, flower, etc.) in front of the sensor (over 3 positions)
Crop Sensor: Sends a signal when, for example, the wheat is fully grown
Bot Chest: Sends a signal depending on the chest state. Possible states are "empty", "not empty", "almost full". The state to be sent is defined while pairing.

Actuators are:

Control Unit: Can place up to 4 signs and steer the bot e.g. in different directions.
Signs Bot Box: Can be turned off and on

In addition, there are currently the following blocks:

The duplicator is used to copy Command Signs, i.e. the signs with their own commands.
Bot Flap: The "cat flap" is a door for the bot, which he opens automatically and closes behind him.
Sensor Extender for controlling additional actuators from one sensor signal
A Timer can be used to start the Bot cyclically
A Delayer can be used to delay and queue signals

More information:

Using the signs "take" and "add", the bot can pick items from Chests and put them in. The signs must be placed on the box. So far, only a few blocks are supported with Inventory.
The Control Unit can be charged with up to 4 labels. To do this, place a label next to the Control Unit and click on the Control Unit. The sign is only stored under this number.
The inventory of the Signs Bot Box is intended to represent the inventory of the Robot. As long as the robot is on the road, of course you have no access.

The copy function can be used to clone node cubes up to 5x3x3 nodes. There is the pattern shield for the template position and the copy shield for the "3x3x3" copy. Since the bot also copies air blocks, the function can also be used for mining or tunnels. The items to be placed must be in the inventory. Items that the bot degrades are in Inventory afterwards. If there are missing items in the inventory during copying, he will set "missing items" blocks, which dissolve into air when degrading.

In-game help: The mod has an in-game help to all blocks and signs. Therefore, it is highly recommended that you have installed the mods 'doc' and 'unified_inventory'.

Commands:

The commands are also all described as help in the "Sign command" node. All blocks or signs that are set are taken from the bot inventory. Any blocks or signs removed will be added back to the Bot Inventory. <slot> is always the bot internal inventory stack (1..8). For all Inventory commands applies: If the bot inventory stack specified by <slot> is full, so that nothing more can be done, or just empty, so that nothing more can be removed, the next slot will automatically be used.

Flow control commands

jump <label>    -- jump command, <label> is a word from the characters a-z or A-Z
<label>:        -- jump label / start of a function
return          -- return from a function
repeat <num>    -- start of a loop block, <num> is a number 1..999
end             -- end of a loop block
call <label>    -- call of a function (with return via the command 'return')

Further jump commands

jump_check_item <num> <slot> <label>  - Check if there are <num> items in the chest like node.
		                                If not, jump to <label>.
                                        <slot> is the bot inventory slot (1..8) to specify the item,
		                                or 0 for any item.
jump_low_batt <percent> <label>       - See "Techage specific commands"

Example with a function at the beginning:

jump main       -- jump to the label 'main'

foo:            -- starting point of the function with the name 'foo'
  cmnd ...
  cmnd ...
return          -- end of 'foo'. Jump back

main:           -- main program
  cmnd ...
  repeat 10     -- repeat all commands up to 'end' 10 times
    cmnd ...
    call foo    -- call the subfunction 'foo'
    cmnd ...
  end           -- end of the 'repeat' loop
exit            -- end of the program

Or alternatively with the function at the end:

cmnd ...
repeat 10       -- repeat all commands up to 'end' 10 times
  cmnd ...
  call foo      -- call the subfunction 'foo'
  cmnd ...
end             -- end of the 'repeat' loop
exit            -- end of the program

foo:            -- starting point of the function with the name 'foo'
  cmnd ...
  cmnd ...
return          -- end of 'foo'. Jump back
