World save not working on Redot 4.4 Alpha 3 'Could not access to filesystem'?

[WithinAmnesia]

How can the Redot 4.4 Alpha 3 version of Voxel Engine VoxelGame demo save world data?
Currently when trying to world save (via pressing the M key in the altered world game script of the linked demo) there are errors not present in the Godot 4.4.1-stable version that make it look like there is an inability of the demo to access engine files related to Redot / Godot in the files. How can this be made better so the world data can be saved successfully?

To recreate this error:

Download:
https://github.com/Redot-Engine/redot-engine/releases/tag/redot-4.4-alpha.3 (I tested upon 'Redot_v4.4-alpha.3_mono_win64.zip')

(This is a demo version of the current VoxelGame with Redot 4.4 Alpha 3 working with Voxel Extension addon also with world save added: Zylann/godot_voxel#785 + #100 (comment) )

Load the demo project of BlockyGame in Redot 4.4 Alpha 3 Mono (I tested upon Redot_v4.4-alpha.3_mono_win64)
Run the project in multiplayer and change a block and press the M key and there should be errors to see.

Please feel free to ask questions and all feedback is welcome.

The latest build of the extension (NOT the module) has a known issue that makes it unable to use Godot's file access classes properly due to an unfortunate difference in APIs. This is fixed in latest dev branch.

[WithinAmnesia]

So if I try to get the extension downloaded from the extension branch directly and bypass the release extension .zip the world saving should work with fix api access? So there is a fix with the file system access classes having a fix in the latest dev branch of the extension and this should work with Redot in theory? I'll try this out and share the findings.

Extension release is 03rd / 03 (March) / 2025

The tags only go to 1.4.1x and that is from before at 29th / 03 (March) / 2025.

Wait a second branch even is the latest dev branch of the extension for voxel engine?

Is the extension in the main master branch or?

[Zylann]

There is no "extension" branch, but building from master should have the fix.

Is there a way to do this so regular people in the creative community can have a .zip of a working extension of voxel engine for Redot 4.4 Alpha 3?

I was thinking I could prototype some test beds and then make a guide to share with the creative community on how to get voxelgame demos working with world save going around the dev community. I usually have to get clean download links and make a small guide to releases and other links so they can fully replicate the same test bed across various set ups. I could build it but then I could not share it properly and it would not scale properly.

I was thinking of trying to add some standard M.M.O.A.R.P.G. features to a VoxelGame test bed and give the polished results back to the creative community to enjoy. Also I was thinking if the publicly available Redot extension world save goes well I can do some collaborations to get a working vertical slice of multiplayer MMORPG features in a demo to give to the creative community. The ability to manually save has been very useful in the Godot side of the creative community but now I'm trying to help grow the Redot side of the creative community.

I have a few features from Godot I wish to port over to Redot testbeds but they require working world saves to share world data back and forth to collaborate successfully. I am sorry for the difficulties but I wish to help give some more features to the voxelgame demo to help onboard more MIT game devs from around the creative community. They like solutions where you download 1-4 things press unzip and use simple steps get it loaded into the engine press run and its on the same page as everyone else. It is hard to get that infrastructure pipeline set up and I commend you for doing so much as it is at this point in time.

I'm not sure what to tell the creative community with Redot. Do they have to wait for a new release version of Voxel Engine Extension that can work with world save and by extension Redot 4.4 Alpha 3 Mono .NET C# . I'd rather let you make proper release builds for the community than ro bungle it on my end plus they can be properly distributed on your end to the creative community with clean download links.

Redot has a game jam going right now and it would help to have easy to access release builds to give to the general creative community to help as many people as possible. Redot 4.4 Alpha 3 with working C# was pressed a bit forward to make the game jam. Redot's official game jam started yesterday at 08th / 08 (August) / 2025 https://itch.io/jam/redot-summer-jam-slam . Please feel fro to ask questions and all feedback is welcome. Keep being awesome:-D!

I usually make a new build every time Godot releases a new version, so the fix will be in the next build.

or Redot 4.4 Alpha 3?

I don't officially "support" Redot, even less alphas. But if Redot is compatible enough you can make your own builds, eventually do some fixes, as stated here.

So Godot is on 4.5 Beta 5 https://godotengine.org/article/dev-snapshot-godot-4-5-beta-5/ + https://godotengine.github.io/godot-interactive-changelog/#4.5-beta5

This could be the next steps are soon to be working on Release Candidates of Godot 4.5 and this might be for August, September, October for the Godot 4.5-Stable version. October seems a reasonable expectation of Godot 4.5-stable release.

With this ~'hyposition' / hypothetical realistic release date of around ~October 2025 / ~Middle Fall of 2025, would this be a practical expectation to tell people when a new release for Voxel Engine Extension could be seen / loosely plan around for the creative community?

So in the mean time it is possible / reasonable to make smaller release builds from the creative community and share those around (as .zips I suppose?) and work with that until the next Godot 4.5-stable launch?

So also it is somewhat understood that orthodoxically with the launch of Godot 4.5-stable (perhaps around October 2025) of which will set in motion your official release cadence for Voxel Engine versions and thus Voxel Engine Extension for 4.5-stable?

This offical release of Voxel Engine Extension should have included the fix for world saving that works with the voxel game demo and theoretically by ~October 2025 / Middle Fall / Autumn 2025 the official version of Voxel Engine Extension releases should work with world save and Godot 4.5-stable and I presume Redot's version of 4.5-stable also.

So one should make a local build test bed and try to get things to work in the mean time, is this what I should tell the creative community and perhaps by conservatively an estimate of ~October 2025 the official release pipeline of Voxel Engine Extension should have built in world save functionality? Does this make sense? All feedback is welcome. Keep up the good work:-D!
