NO PORT TO FORGE PLANNED! (but feel free to port it by yourself and link it)

Description

This mod allows you to change the way the worldspawn is set! Whether a player is joining an old server for the first time or a player died with no spawn point set, this player will roll the dice to set a new world spawn location. The random location is chosen in an area around the online players that you can customize.

For a better experience with the mod, its configuration can be changed directly in-game through new commands!

This is a short description, full description below.

FAQ

• Do I need it on my server? Yes. This mod is server side, so you don't need it on your client

• Can I include it in my modpack? Yes, you are free to include this mod into your modpack

• For any other things: Feel free to share your experience, problems, enhancement ideas in the Discord server, or directly creating issues on the GitHub

Full description

If the changing area is enabled (the main purpose of the mod), when a player joins a server for the first time or dies without a spawn point set, a new worldspawn is randomly set around alive and online players from the Overworld.
Note that if no other player is found, last worldspawn will be used.

Area Shape

The shape of the area from which a random position is chosen may not necessarily contains every player. This is only the case for the BOX shape. If the player influence is different from NONE, even the BOX may not contain every player.
If only only one other player is found, the shape is necessarily a point. So, unless an expand is set, the worldspawn will be set to the other player's position.

• BOX: A box containing every player
• CIRCLE: A circle centered on the box, with a radius equals to the longest side of the box. If players are far from each other in one direction, this shape will contain a lot more of "empty space". Note than this is not yet the smallest bounding circle.

Player Influence

To avoid the area being too big (with too much "empty space") or too far from players, a player influence can be set. This means if there are more players in one side of the shape, the world spawn will be more likely on this side.

• NONE: No player influence on the shape
• AREA OFFSET: A weighted center is computed and the shape is moved toward this new center
• AREA SHRINK: A weighted center is computed and the shape is shrink in a way that makes the shape's center match the computed one

Expand

The area, no matter the shape or the player influence, may be too small if you want to encourage a bit of running, even though this mod aims to avoid loooong runs. So, you can set an expand value that will expand the shape of this number of blocks in every direction.

Spawn Chunks

In Minecraft, worldspawn chunks are always loaded. Having a worldspawn that can change might be annoying if you plan to setup always loaded machines. Also, it could possibly create lags if your server is not very efficient and your worldspawn chunk radius (future gamerule) is too big.

To avoid this, you can set the (0,0,0) to be the position used for the worldspawn chunks with an option of the mod. You can always update this behavior with the command, but note that the change will be effective only after someone joins or dies.
