Simple Tsunamis
by RemyEliot
Simple Tsunamis, a NeoForge mod for 1.21.5, adds several kinds of tsunami that sweep across the terrain, each carrying a different fluid, block or entity.
What it does
Each tsunami type is a wave of its own material. The catalog lists a Water Tsunami, a Lava Tsunami, a Void Fluid Tsunami, a TNT Tsunami, a Mob Tsunami and a Glitch Tsunami. Players set one off in the world, and the wave moves outward carrying its contents with it, so the effect spreads over an area rather than a single block.
The mod is marked as an alpha release, and its author notes describe the tsunamis as experimental. One fact is stated plainly in the notes: players cannot craft the tsunamis, so they are not obtained through recipes. The author also mentions a planned sequel named Simple Tsunami's 2, which is not part of this release.
Only the NeoForge loader is supported, and the build is published for 1.21.5 alone. Both the server and each player need the mod, since it runs on the client and the server together. It is distributed under a custom license and is not open source, and the source code and issue tracker are publicly available.
Key features
Water tsunami
A wave of water that floods the area it passes over, the most basic of the tsunami types.
Lava and void fluid waves
Tsunamis that carry lava or a void fluid instead of water, changing what the wave leaves behind.
TNT and mob waves
A TNT tsunami spreads explosive blocks across an area, and a mob tsunami carries entities along with the wave.
Glitch tsunami
A tsunami variant listed among the mod's types, with its own contents from the glitch theme.
