Introduction

Hengo is a node-based visual scripting tool for the Godot editor. You build game logic on a graph canvas of connected nodes, functions, variables, signals, states and actions, instead of writing GDScript by hand.

Hengo doesn’t ship a runtime interpreter: it compiles your graph to real GDScript, so the output is plain, readable code that runs with zero overhead.

Highlights

Compiles to GDScript: the graph is the source; clean .gd files are the build.
State machines: a first-class finite-state-machine system, drawn and edited on one canvas.
Actions: Playmaker-style steps you drop on a state (see the Actions reference).
Extensible: an action is a small GDScript file, so your project can add its own.
Live debugger: watch execution flow across the graph while the game runs.
