Customizable Player Spawn

Spawn points are defined in a config file. A spawn can be a single shared point for every player, or a separate structure for each player. The mod can place a structure from a .nbt template, read a vanilla structure marker block to set the spawn relative to the structure center, or spawn players directly without placing anything. The target dimension and allowed biomes can be chosen for each spawn.

Before a structure goes down, the mod scans the heightmap for a usable surface and tests the footprint for hazards such as dangerous blocks, fluids, tree overlap and uneven ground, or it can place the structure at a fixed Y level. The volume is then cleared, support gaps are filled, lighting is refreshed and markers are processed. Generated spawn structures can optionally be protected against block placement, container access, explosions, fire and fluids. The mod suits modpacks and prepared worlds, where a starter ruin, house, island, lobby or intro area should be the first place a player sees.

The mod is installed on the client and the server, so both sides need it. Files are published for Fabric, Forge and NeoForge, for game versions 1.20.1 and 1.21.1. The code is released under the MIT License and is open source.
