[Mod] Signs Bot [signs_bot]

[joe7575]

A robot controlled by signs.



The bot can only be controlled by signs that are placed in its path.
After starting, the bot runs in the default direction until it encounters a sign. There, the commands on the sign are processed.
Signs are available for many standard tasks.
There is also a sign that can be programmed by the player, which then is processed by the bot.
But there are not programming skills needed, Bot commands are similar to chat commands.

Further 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, by means of the Connection Tool. Click on both blocks one after the other. A successful pairing is indicated by a ping / pong noise.

When pairing, the current state of the actuator is important.
The state of the actuator is saved with the pairing and restored by the received signal. For example, the robot can be switched on or off 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 can 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 block (tree, cactus, flower, etc.)
• Crop Sendor: Sends a signal when, for example, the wheat is fully grown

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
• 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.

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

More information:

+ Spoiler

• 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.
