Branch

Overview

Like a branch on a tree, the Branch Node splits a single path into two diverging paths. Which branch of logic is executed depends on a single condition, which can itself be composed of multiple conditions. At a high level it basically means "If this is true, do this; if not, do this." which sounds relatively simplistic, however, branching is a foundational concept of creating interactive logic, similar to using if statements in programming, and when combined with Relational Expression, Pulse Flow and Logical Operator Nodes, we can build incredibly complex systems.

Uses

There are infinite uses for the Branch Node, however a very basic example would be a single Input condition, which triggers one of two functions. In the example below we use a Variable to represent whether the unit of measurement for distance is set to km/h or mph, and trigger functions to display data in the corresponding format.

Basic example of the Branch node.

These conditional statements can be chained together and combined with other Nodes. Below is an example where the Logic checks:

1. If the passenger seat is occupied. If it is (true) then...

2. It checks if the passenger seat belt is fastened. If it isn't (false) then...

3. It sounds an alarm.

An intermediate example of the Branch node.

Inputs

Input	Type	Description
Pulse Input (►)	Pulse	A standard Input Pulse, to trigger the execution of the Node.

Outputs

Output	Type	Description
OnTrue	Pulse	Triggers the execution of subsequent logic if Input condition is True.
OnFalse	Pulse	Triggers the execution of subsequent logic if Input condition is False.
