The dialogue system contains two different nodes to branching your conversation.

The branch node will continue the execution flow based on the condition it receives as a boolean input (true or false).

Similar to the previous node, but instead of a boolean, it uses an integer condition. You can define pins with intervals in the inspector. You can add, remove, or reorder pins at any time.

The node grabs the integer input and selects the first interval from the list that contains this number. You can set the interval 1 number long (for example 1-1) in which case it works as a simple switch.
