0.0.8: Qt upgrade + fixes

2025-03-31

Beta version 0.0.8 is here.

A few weeks ago we began writing a "HUD tutorial" for use inside FPS games, however we noticed a crash occurring depending on some bewildering factors, which sent us on a week-long debugging session. Turns out there was a bug in Qt's compositor, and thus we had to upgrade our Qt dependency.

For Linux, we went from Qt 6.7.3 to 6.9.0-rc1, and on Windows from Qt 6.7.3 to 6.8.2 (with some backported patches from 6.9.0-rc1).

A welcoming side effect of this change is that this reduced the minimum total install size on Windows, the addon went from 370mb to 250mb.

So, our new versions are:

Windows

  • Qt version: 6.8.2
  • Chromium version: 122.0.6261.171
  • With security patches up to: 132.0.6834.111

Linux / macOS

  • Qt version: 6.9.0-rc1
  • Chromium version: 130.0.6723.192
  • With security patches up to: 133.0.6943.141

Quick renderer

In our blog post about 0.0.3 we mentioned the QuickView node.

We did some work on this node so it renders QtQuick content, like this splash screen:

DebugMouse

You may wonder, how does this benefit me, well there is a DebugMouse component now, which helps debugging mouse positions when you find yourself projecting the webview onto weird 3D shapes.

In addition, using this QuickView node, we will introduce more components for debugging purposes, as well as introduce completely new Godot nodes based on QuickView, such as e.g VideoPlayerFFmpeg (more information below).

FFmpeg

We are now including the LGPL3 version of FFmpeg with this addon, with the goal of eventually introducing a multimedia node that is able to handle a wide range of codecs for video (and webcam) playback.

As you may be aware, Godot includes a videoplayer, but it only supports Ogg Theora (.ogv). In addition, it comes with limitations like not being able to seek, or streaming from URLs - our implementation would be able to do those things, hardware accelerated.

Unfortunately we could not quite get the videoplayer finished in time for this release. Next version is likely.

Note: this increased the size of the addon by some 120mb, however these FFmpeg libraries are optional.

Nested context objects

Release 0.0.6 introduced "context objects" - a way to expose Godot nodes to the javascript runtime.

We received some feedback regarding the inability to pass nested dicts and arrays. As this is a common use-case, we decided to support nesting, and accept the downside that this feature is now technically slower (for arrays/dicts). However, the impact is negligible during normal usage.

If you were planning on sending huge amounts of data back-and-forth using arrays/dicts, let us know, and perhaps we'll introduce types for that (FastArray/FastDict).

vsync + linux

We identified issues with vsync enabled on Linux, so we disabled the ability to run with vsync (on Linux). It will show an error if you try to do so.

We consider it low priority for now.

Documentation

We improved the documentation in various places. For example, we added some information on how to correctly include images (.png/.jpg) during exporting: exports/images, as well as improve the Context Objects documentation.

Small fixes

This blog post features some of the highlights. We fixed more things that are not mentioned in this blog post.

Community spotlight

It is always nice to see what users make with this addon. "SirReality" on Discord is making a game that uses this addon for the menu, which uses React 19, and Tailwind CSS.
