Is HxGodot still maintained?

No, HxGodot is no longer maintained. The README states it was an experimental project that didn't live up to its vision due to complexity and time constraints, so it's abandoned without future updates.

How do I set up HxGodot for Godot 4?

Install Haxe and hxcpp, use the CLI tool 'haxelib run hxgodot init' to generate a sample project, then build with SCons for your platform. Be prepared for a complex toolchain including C++ compiler and Python, as detailed in the prerequisites.

HxGodot vs C++ GDExtension: which is better?

C++ GDExtensions are the standard, supported way to extend Godot with native code, offering stability and documentation. HxGodot is an unmaintained experiment that adds Haxe syntax but introduces complexity and risk, so it's not recommended for most use cases.

How to handle GDArrays safely in HxGodot?

Avoid naive usage; explicitly cast Variants to their original type first to prevent crashes. For example, cast to cpp.Int64 before converting to Int, as shown in the 'Dangerous GDArrays' section of the README.

Can I use HxGodot with a custom Godot version?

Yes, but you must generate custom bindings by running Godot with --dump-extension-api-with-docs, then regenerate bindings in your project using the CLI tool. This adds manual steps and potential compatibility issues.

What are common crashes in HxGodot?

Crashes can occur from missing API functions, improper GDArray handling, or stack corruption due to Variant casting issues. The README warns of undefined behavior and recommends testing only in smaller projects.

What is HxGodot (Godot 4.0)?

HxGodot is a GDExtension for Godot 4 that enables developers to write game nodes in Haxe, which are then compiled to C++ via hxcpp and integrated as native nodes in Godot scenes. It provides an alternative workflow for Godot game development by leveraging Haxe's syntax and cross-platform capabilities, though it was an experimental project that is no longer maintained.

Target Audience

Godot 4 developers who are already familiar with or interested in the Haxe programming language and want to use it for writing game logic and nodes within the Godot engine.

Value Proposition

Developers might choose HxGodot to combine Haxe's expressive syntax and selective compilation (which optimizes extension size by including only used classes) with Godot's powerful engine and editor, offering a unique integration that generates automatic bindings for Godot's API.

Overview

A Haxe GDExtension for Godot 4

Use Cases

Best For

Godot developers wanting to write game nodes in Haxe instead of GDScript or C++.
Projects aiming to leverage Haxe's cross-platform compilation capabilities within the Godot engine.
Developers needing automatic generation of Haxe bindings for Godot's API, with support for custom Godot versions.
Experiments or smaller projects exploring alternative workflows for Godot 4 game development.
Scenarios where selective compilation to optimize extension size is a priority.
Generating starter projects with examples and build configuration via a CLI tool for quick setup.

Not Ideal For

Production games requiring stable, long-term support and maintenance
Developers unfamiliar with C++ build tools, SCons, or the Haxe toolchain
Projects that need full, reliable access to Godot's entire API without missing functions or crashes
Teams seeking a straightforward, out-of-the-box solution without manual binding generation and updates

Pros & Cons

Pros

Haxe Language Integration

Allows writing Godot nodes in Haxe, compiled to C++ via hxcpp, offering expressive syntax and cross-platform capabilities, as demonstrated in the sample project generation.

Automatic Binding Generation

Generates Haxe bindings for Godot's API automatically, with support for custom Godot versions using the --dump-extension-api-with-docs command.

Selective Compilation

Haxe's compiler includes only classes actually used in the code, optimizing extension size by avoiding bloat, as noted in the 'Good to know' section.

Starter Project Tooling

Includes a CLI tool to generate a complete sample project with examples and build configuration, speeding up initial setup and experimentation.

Cons

Abandoned and Unmaintained

The project is no longer maintained, with the creator admitting it was an experimental failure due to complexity, meaning no bug fixes, updates, or support.

Complex and Fragile Setup

Requires a specific build environment matching Godot's, including C++ compiler, Python, SCons, and Haxe toolchain, with manual steps for binding generation and updates that are error-prone.

Incomplete and Unstable API

Explicitly warns of potential crashes, missing API pieces, and issues like dangerous GDArrays that can cause stack corruption, making it unreliable for serious development.
