Add support for convex selections visualization, if at all possible.

Spigot server stopping responding after region select. Also this happens always if i try to select sphere region with for exapmle barrier particles.

If I have the world edit wand in my selected hotbar slot and create a selection it shows the partials. If I then clear my inventory either with commands, creative inventory or another plugin the partials stay visible. This is fixed when giving myself the world edit wand and changing the slot on and off it.

This is a feature request to add the ability to represent the selection points, such as by replacing the blocks at the points.

The purpose of this is to make it easier to move one (or both) of the points if you don't remember where it was placed. For example if you've got a cuboid, and you don't know which corner has point 1, you just have to set point 1 and see what happens. This is even more problematic when you're restoring a selection (such as from clipboard, or a WorldGuard region), as then it's even more difficult to remember which corner is which.

It would be nice if this functionality were also available without a complete selection defined. Meaning if you select point 1, but there is no point 2 yet. But I wouldn't consider it an absolute requirement.

Instead of showing all the big bad stack traces to users, use Sentry to log them and react to them before users can even report those :)

Latest worldedit beta is not compatible with WorldEditSelectionVisualizer, please update the hook for the Vector class

I am using FastAsyncWorldedit for my worldedit plugin

WorldEditSelectionVisualizer v2.0.7
Papermc 1.16.5
Java 11
Debian 10

Server is 1.19.2 with Bukkit/Spigot. When wesv is enabled and toggled on it only marks one block with particles.

Its only the happy villager particle that works and its as I said only one block. No matter what I try to create its only the origin block that is visualised, nothing else.

How can I prohibit the use of the /wesv lock command?

This will be the first class to write Unit Tests for. We'll test the methodology on it and apply a satisfactory result to other classes when unit testing.

Also, Code Coverage should not be omitted.

Some nice JavaDoc should be generated at least from the Metrics class by now, so it's time to put that claim to test :)

in the config, primary and secondary particles are set to 'FLAME" and 'REDSTONE' respectively. what other materials are supported?

Getting a ClassNotFoundException error with Spigot 1.13.1,

Implement a timeout that would hide particles after a configured amount of time (default = 0, i.e. disabled, >0 = amount of time in seconds to wait before the fade).

NOTE: Since WESV is dependent on WorldEdit's current selection, fading particles would mean I would need to cancel that selection after the timeout, which is probably not what most people would want. Anyone wanting to work on this should take this information into consideration.

Add an option in the config to disable it by default.
-only enable when players toggle it.

Right now its on by default and players complain. For me it's useful so I'd want it but don't want to bother the others.

Thanks

Since Hidendra's MCStats are down for a prolonged period of time (just check its issues - https://github.com/Hidendra/mcstats.org/issues), I'm opting-in to exchange them for the shiny new BStats (https://bstats.org)

It seems that WESV doesn't check whether the player is online.

I've noticed that this plugin is not compatible with FAWE, and throws an error saying it didn't find worldedit on server start.
Would it be possible to support it?

Currently running paper 1.12.2
plugin version is 2.0.3

might be due to me running an older version but just wanted to send you this either way

When a selection is copied to the clipboard, then the clipboard is rotated (//rotate 90 for instance) the clipboard visualizer stays in the same position instead of rotating with the clipboard.
WorldEditSelectionVisualizer 2.0.1
paper 1.14.3 build 134

Right now, only side particles are being displayed, for performance reasons. Top + bottom display should be possible but needs a good implementation + optimizations to not cause client-side lags.

Can you make a reload command for configuration file in your plugin?

As I saw clipboard marking is currently not implemented. As this would be an essential feature for me, I'm gonna work on that tomorrow. Shouldn't be too difficult.

For this I'll make a fork and implement it there. If it works I'll open up a pull request.

I'll provide an additional option in the Config for an additional particle as well as a new command to enable clipboard marking.
I have studied the API of worldedit thoroughly and am confident in accomplishing this task. There is only a minor issue. Although I have over 11 years of expertise in programming and Java I have never written a bukkit plug in before. Could you possibly guide me through the build process of a plug in? That would be awesome so I don't waste a lot of time in trying to figure this out too.

Thanks in advance and for your great work.

If I select more than about 100 blocks, my FPS drops to 0 FPS. I used to use a similar plugin, and it didn't cause such lag, even when selecting thousands of blocks. Is there some setting I can tweak to improve this?

I can consistently cause a full server freeze with FAWE and WESV by changing to a "fuzzy" selection and then to a cuboid selection. Both have their default configs. I think it might have something to do with fuzzy to cuboid causing a huge selection as changing from fuzzy to ellipsoid shows the message for having a selection above 50k blocks, without crashing. I tried reducing the visualizer limit to 1000 but it made no difference.

FAWE commands:
//sel fuzzy
//sel cuboid
