The Value Selector building block is used to detect certain Number values.
A Value Selector building block has one Number input and one ON/OFF output. The output value will be ON if the input value is one of the values that the building block has been configured to accept.
To configure a Value Selector building block, select the values in the Inspector window that should cause the output to turn ON. The block can also be configured to ignore input values that do not cause the output value to change.
In the example to the right, the output of the building block will turn ON if the input is either 1, 2 or 3. If the input is any other value, then the output will turn OFF.
