To implement the PluginBloxel for your Minecraft-style game in Rust using Bevy, you'll need to design your WorldGrid type along with appropriate traits, components, and systems to manage the voxel grid, entities, and interactions.

Types and Components

IVec3: Already provided by Bevy for grid coordinates.
WorldGrid: Manages the entities in the voxel grid.
Block: Represents a 1-meter cube making up the terrain.
NonBlockEntity: Represents non-block entities like tables, chairs, buttons, etc.
SubGrid: Represents nested WorldGrid instances.

Bevy Bloxel Plugin Design Notes

This document is just scratch notes for a plugin for Bevy to manage a block-type world like in Minecraft.

Features

This plugin, to be useful, must provide a number of things.

Ability to create, damage, and destroy blocks in an aligned grid.

An attempt to explain step-by-step how FM synthesis calculation works.

OPL3

Using the OPL3 as an example, there are several components:

Vibrato feeds into the phase generator (PG) to modulate its frequency
Tremolo feeds into the envelope generator (EG) to modulate its amplitude
PG and EG feed into the operator
Operator outputs to the next operator

These papers cover social choice, public choice, and voting theory. See the Handbook of Social Choice and Voting by Heckelman and Miller; or Collective Decisions and Voting by Nicolaus Tideman.

Voting rules and analysis

These are analyses of voting rules or other theoretical analysis independent of political conditions. This stretches as far as analyzing how and when voters behave strategically under particular systems, although that's more blurry.

Ordered preferences X≻A → if X is not a candidate, voter votes for A

14: Alex≻Bobbie≻Chris≻Dane  \
12: Bobbie≻Alex≻Chris≻Dane   | ← 51% majority, doesn't count.
25: Chris≻Bobbie≻Alex≻Dane  /
49: Dane≻Chris≻Bobbie≻Alex  ← Most votes, wins plurality

Instant runoff voting:
