The "Randomizer" block allows you to set up a randomizer inside your script.

How to set up

The block has several distribution groups, at least two, but no more than ten. Each one has a percentage probability. The percentage value shows with what probability the user will get to the given branch of the scenario.
The sum of all percentages can be more than a hundred. Although the bot will write that this needs to be corrected, it will work with the set percentage.

Basic tuning

The "Randomizer" block has a basic setting - the bot remembers which scenario the user went through and directs him along the same path when he hits that step again. To randomly select a scenario triggered each time the user enters this block, you need to put a checkmark in the settings "Random selection each time you enter".
