Node Quick Reference

This page provides a high-level overview of all available nodes in ERGS Studio, categorized by their primary function.

Logic Engine

Node Name	Short Description
AND	Logic gate: true if all inputs are true.
OR	Logic gate: true if at least one input is true.
NOT	Inverts the input signal.
IF	Basic conditional comparison between two values.
IF with values	Outputs a specific value based on a comparison result.
Case	Triggers an action based on an exact match from a list.
FlipFlop	Alternates between two actions with each trigger.
Pulse if true	Generates a temporary "on" signal or burst of signals.
Debounce	Filters noisy inputs by requiring stability over time.
Auto increment	Charges/discharges a value based on an enable signal.

Node Name	Short Description
ADD / SUB	Basic arithmetic addition and subtraction.
MUL / DIV	Multiplication and division (scaling and ratios).
MAP	Scales a value from one numerical range to another.
Lerp	Smoothly interpolates between two values based on a percentage.
SIN	Generates smooth oscillations and waveforms.
Smooth value	Transitions to a new value over a specific duration.
Eval expression	Calculates complex multi-variable mathematical formulas.
Random (int)	Generates a fixed random number on demand.

Node Name	Short Description
Concat	Merges multiple text strings into one.
Join strings	Aggregates strings conditionally with a separator.
Substring	Extracts a specific portion of a string.
Replace	Swaps occurrences of text within a string.
String by language	Retrieves localized text from the project's string table.
FuzzyWuzzy compare	Measures similarity between strings (handles typos).

Node Name	Short Description
MQTT Reader/Writer	Sends and receives data via the MQTT broker.
RGB -> DMX	Maps color objects to DMX fixture addresses.
DMX writer	Granular control over standard DMX channels.
MQTT Audio/Video	Remote control for network-based media players.
VoIP SIP phone	Bridge for interactive telephone puzzles and DTMF detection.

Node Name	Short Description
set Game State	Records a milestone or checkpoint in the game.
get Game State	Checks if a specific objective has been met.
onBeginPlay	Triggers logic initialization when the game starts.
ping	Monitors the network status of IP-based hardware.
Simon Says	Integrated engine for sequence-memorization games.
Chess board	Manages board state and validates legal chess moves.

Node Name	Short Description
behavioural root	The entry point for status-driven automated logic.
behavioural selector	Executes the first child that doesn't fail (Priorities).
behavioural sequence	Executes children in order until one fails (Checklists).
behavioural action	Bridges the tree logic to standard ERGS actions.
