Branch node pin reference — Condition True False

Internal pin names: True path is 'then', False path is 'else'. Display names show True/False.

Branch — conditional if/else flow control

Branch

Splits execution into True / False paths based on a Boolean condition. The most common decision node.

Switch

Routes execution based on the value of an integer, name, or enum. Cleaner than chained Branches for >2 outcomes.

string

string

Cast To

Safely converts an Object Reference to a more specific class. Branch on the Failed output — casting to the wrong class returns null.

IsValid macro — check validity with exec branch outputs

K2Node_MacroInstance from StandardMacros. Has exec pins unlike the pure IsValid function.

BooleanAND — logical AND

OR=BooleanOR, NOT=Not_PreBool, XOR=BooleanXOR

Macro

An inline-expanded subgraph. Like a function but each use creates a fresh copy at compile time (faster, but more bytecode).

OR Boolean — logical OR of two booleans
