Server setup (please complete the following information):

• Minecraft Version (run /version ingame): This server is running Purpur version git-Purpur-1053 (MC: 1.16.5) (Implementing API version 1.16.5-R0.1-SNAPSHOT)
  You are running the latest version
  Previous version: git-Purpur-1011 (MC: 1.16.5)
• VarLight Version (run /version VarLight ingame): 1.12.8
• Java Version (run java -version in the terminal): Java 14

Is your feature request related to a problem? Please describe.
Ye sort of when you do the command to update the light you get an message to all the users [Username: [Varlight] Updated Light levet at [x, y, z] in world "world" from x to x] thats irritating

Describe the solution you'd like
I like to get an option in the config to disable the message that says someone updates the light level

Describe alternatives you've considered (optional)
None because i found nothing to disable the message or i looked over it

Additional context
Nope nothing to add.

Spigot 1.15.2 (Jenkins 2622)
LightAPI 3.4.2 (bottomdumber fork)
VarLight 1.8.2-MC-1.15.1 (there is not 1.15.2 version)

We are seeing quite a few of these as we move around. There is only one VarLight configured, in a different world.

Not sure if it's a bug or something that's purposely implemented, but it's currently not possible to use the plugin on stairs, slabs, walls/fences or glass (or glass panes) on 1.15.

We're currently needing a light plugin that will work on glass, the way addlight used to. If it's not purposely done due to issues, would it be possible to implement this for us?

Thank you

Is your feature request related to a problem? Please describe.
I needed to relocate huge buildings about 50 blocks downwards, now I need to relocate light sources made using VarLight as well.

Rewriting the files directly won't work, because VarLight does not reapply light data on server load. Better wording: I rewrote NLS files successfully, but since server won't reapply light on load, then it's not useful out of the box

Describe the solution you'd like
A way to reapply all light sources to the world.

Describe alternatives you've considered (optional)
Current alternative is to read NLS myself and call out API - haven't tried that yet. get all loaded NLS files, grab all light source positions and call updateBlocks in NMS adapter - works fine.

Additional context
None

https://paste.gg/p/anonymous/456a2b1b2c864c2389fd04e3086f445c

Would be nice to API into and use for updating block light levels

Please consider adding a permission to view a (specific) light source. Use case: VIP (for example) can see the light, other (lower) ranks cannot.

Is this possible?

Cause

If the buffer is [0x00, 0x00, 0x80], the result will be -128 instead of 128
or
If the buffer is [0x00, 0x00, 0xFF] the result will be -1 instead of 255

Solution: Wrap each read byte using Byte.toUnsignedInt()

You can see that a lot of ram it's used by VarLight.
I can give you access to the memory dumb if needed

Describe the bug
When running a Redstone clock, and having it push pistons, it causes lots of lag.

To Reproduce
Use world edit to varlight fill a large area, then create a piston that gets rapidly pushed up and down with a Redstone clock. You will see that it slows the server down immensely. It appears to be more effective to first fill the area with light, then remove varlight. The area stays lit, and Redstone functions without lag.

Expected behavior
The piston goes up and down at a normal speed

Server setup (please complete the following information):

• Minecraft Version (run /version ingame): 1.16.4
• VarLight Version (run /version VarLight ingame): 1.12.8
• Java Version (run java -version in the terminal): 14

Additional context
Add any other context about the problem here.

In the SpigotMC resource page, it looks like DonkeyServer is experiencing the exact same issue in his review.

Stacktrace

I do not want to be the bearer of bad news but I have discovered a pretty big bug with the plugin. I don't know if this was the case with previous versions of minecraft and the plugin but I it happens with the current version in 1.16.1.

The plugin stops news end cities from generating in unexplored chunks which is a pretty major thing. It will not affect end cities that has already been discovered ans saved to your region files prior to installing the plugin but it stops the generation for any still out there. If you find it hard to believe, teleport yourself to an existing end city in your world, and look at it. Log out, stop the server, and delete the region files for the end dimension (in order to force the game to regenerate structures). Start the server back up, log in, and the end city that was previously there is now gone. If you do the /locate endcity command, it will still tell you that you are literally standing at the end city but it won't be there anymore, and with all region files being reset, the whole dimension will be void of end cities. I discovered this yesterday after I couldn't find a new end city after travelling for hours which then forced me to do the /locate command in order to have exact coords to go to, only to get there and there being no end city at all. I then had to do the painstaking task of removing all my plugins one by one, deleting my end region files and rebooting the server until I finally discovered that varlight was the culprit which was sadly one of the last plugins I tried to remove in my quest haha.

Spigot 1.14.4 (Jenkins 2468) git-Spigot-065a373-03b145b (MC: 1.14.4) (Implementing API version 1.14.4-R0.1-SNAPSHOT)
LightAPI 3.3.2
VarLight 1.4.5-LightAPI-1.14

This error occurs occasionally, and randomly. There are no players on this test server. The stack trace does not identify any plugins, but it appears to be related to lighting. I do not recall seeing this error prior to VarLIght. So I'm wondering if the stack points to something useful. Any help appreciated.

When creating a new light source directly next to another existing light source, the existing light source gets reset to 0.

Potential fix: update the existing light source similar to other block update events

When x2 - x1, y2 - y1, or z2 - z1 evaluate to 0, the iterator gets stuck in an infinite loop

Cause

Version-independent

I did the following in a frozen_tundra biome

• Construct a large pond
• Watch the pond ice over
• Add barriers above the pond
• Add VarLight light sources to the barriers, level 15
• Watch the pond ice melt, and not replenish
• Remove the barriers with WE //cut

Since the blocks weren't technically broken, the light sources were not removed, and the pond remains unfrozen. I count this as a desirable feature, but want to confirm that is the intent. If it is not, and you intend to "fix" it, please make it a configurable option if possible.

I tried to run the plugin at https://github.com/YatopiaMC/Yatopia but it doesn't load and doesn't work, so I guess it's not supported, but I want to ask if it would add support ..?

The problem has to do with Varlight not updating block light levels. I used varlight fill on a large area (433x757) and not all the blocks were emitting light, despite when using varlight debug the blocks being listed as emitting light level 15.

To Reproduce

1. Set chunks to load to 5
2. World edit in a 433x757 size map (using FAWE)
3. Run varlight fill with a ∆Y of 100 on the entire map.
4. Stand in one place of the map.
5. Use --forceUpgrade and --eraseCache on next launch of server.
6. There will be no light.

Expected behavior
None of the varlight-ed blocks will emit light. However, when placing a block they will.

Screenshots

Server setup (please complete the following information):

• Minecraft Version (run /version ingame):

• VarLight Version (run /version VarLight ingame):

• Java Version (run java -version in the terminal):
  OpenJDK versin "1.8.0_252-b09"
  OpenJDK Runtime Enviornment (build 1.8.0_252-b09)
  OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

Additional context
The Varlight Command seemed to stall at 100% completed overnight when I was running it.

Is your feature request related to a problem? Please describe.
With nothing else to do this weekend, I decided to experiment with Purpur. VarLight is unhappy, no doubt due to the StarLight reimplementation of lighting. (So probably incompatible with Tuinity also.)

Describe the solution you'd like
Whatever is required.

Describe alternatives you've considered (optional)
Initial inquiry.

Feature requests and questions:

• Update check should be configurable option. I have an automagical update checker, so do not need VL to check.
• How is latest version being checked? My network interceptor does not allow outbound network connections, but I don't see that any have been attempted.
• Configuration save options seem to have disappeared. What are the save options now? I do not see a save being logged, and the file timestamp has not changed.
• Please provide configuration option to remove color formatting from console/log and in-game messages. Or better, a localization file for all messages.
