Notes

It's the start of a new release cycle and we have a huge update for you this week! It's hard to summarise all the changes (see the full list below), but a key highlight is you can now use Progressive web app (PWA) installation with the Browser object. While all web exports from Construct are already PWAs, this allows you to use the same 'Install as app' feature that Construct itself provides, prompting the user to create an icon on their desktop/home screen. It's currently only supported in Chrome and Edge. There's also a new ability to add screenshots in the Project Bar, which is intended for PWA installation: if you add at least one screenshot in both the wide and narrow form factors, you'll get the richer install UI for your PWA.

We've also done a lot of work on the WebGPU renderer. By now we think it is close to complete in terms of having similar features and reliability to WebGL, and soon we may start enabling it by default. While we were working in the rendering engine, we also added a new option for effects to opt-in to direct rendering with 3D objects, which potentially provides new capabilities for 3D shaders. The GPU profiler in the debugger now also includes both the self and total time for layers, which is useful when using sub-layers.

There's loads more, including new additions based on feature requests in all sorts of places, including Find All References, the Timer behavior, and the Touch plugin. We've also added autocomplete for animation frame tags to help make it easier to type them in event sheets. There's an absolute boatload of bug fixes and other changes and improvements, notably including that worker mode is now disabled by default again in Safari due to Safari bugs that cause problems with it. Happy testing!

  • I love the huge amount of bug fixes and am very intrigued by the direct 3D rendering option!

    • So we have to define it in the addon.json and then should handle the depth writing ourselves (i.e. discard pixels) I guess? Sounds very useful!

      (I always wish there was some temporary documentation for some beta features so it's easier to test)

        Add "supports-3d-direct-rendering": true to addon.json and the effect compositor will not force a pre-draw. There could be other cases where it forces a pre-draw though, it depends on the effect.

  • Wonderful news on opt-in to direct rendering with 3D objects! This will allow us some interesting effects with 3D shapes and objects.

    We need one more thing for 3d shape fragment lighting.

    Can you please add a varying output to the default vertex shadet, just passing through aPos, so we know the world position of the fragment.

    So please add in webgl2 vertex shader: out highp vec3 pos; and in main(): pos = aPos. Also, please do the equivalent for webgl and webgpu. This will get the frag shader the world coordinates needed for world based frag lighting.

    If the following shader does not use pos, it will allow the shader compiler too compile it away. Even if it does not compile it away, it would seem to have small impact.

    I will also add this to the c3 2024 suggestion platform.

    Thank you for the consideration and great beta release.

  • Thanks a lot for litteraly double-release :)). I appreciate the endless passion and persistence in development.

  • Nice "touch" option.

  • Wohoo \o/ very excited about my PWA install suggestion already getting implemented.
