When to change transition priorities
All blue transitions automatically have a top priority of 1, and green transitions - have a priority of 99.
Transition priority indicators can be changed by specifying a lower priority for a transition and a higher priority for a transition.
The virtual assistant moves through the dialog by priorities. The first step is to check the blue transitions connected to the state (with priority 1) and whether the conditions of any transition meet the criteria so that the conversation can move on. If there are several blue transitions connected to the state and their priority number is the same, the bot chooses one of them randomly. If none of the blue transition conditions match what the virtual assistant is looking for, the assistant checks all green transitions in the scenario (with a priority score of 99). If the conditions and priorities for green transitions are the same, the virtual assistant chooses one of them randomly.
Each virtual assistant usually has at least one green transition with a lower priority of 100 or even higher score. There is no intent and no entity specified for this transition. It is an unconditional transition that works when none of the intents from the virtual assistant knowledge base are detected in the user text. The virtual assistant checks all green transitions in the scenario, and when cannot find the condition it’s looking for - gets to this - the last transition with an answer in which the virtual assistant says it doesn’t know and can't reply.
There are many scenarios where the above-mentioned change of priority is the only such case, but there could be more specific scenarios where the change of transition priority is used more frequently.
For example, in various test types and other such dialogues, where the sequence of checking the transitions is important for moving the conversation in the right direction. You can put the first priority on the transition you want, ensuring that the virtual assistant will check it before all other transitions, and the second priority on the remaining transitions.
