-# Contributing Guidelines
-
-This document lists conventions adopted by Progressia developers.
-
-## git
-
-### Branches
-Progressia repository contains a `master` branch and several "feature" branches.
-
-`master` is expected to contain a version of the game suitable for demonstration and forking/branching. Do not commit directly to `master` without OLEGSHA's approval.
-- `master` must always correctly build without compiler warnings (see below).
-- `master` must always pass all unit tests.
-- `master` must always be able to launch successfully.
-- `master` must always only contain working features.
-- `master` should not contain excessive debug code.
-- `master` must always have its code and filenames formatted (see below).
-
-"Feature" branches are branches dedicated to the development of a single feature. When the feature reaches completion the branch is merged into `master` and removed. Intermediate merges into `master` may occur when some fitting milestone is reached. Intermediate merges from `master` may be done as necessary. Merges between "feature" branches should generally be avoided.
-
-When beginning work on a new feature, create a new branch based on `master` (or on another "feature" branch if absolutely necessary). Use `all-small-with-dashes` to name the branch: `add-trees` or `rebalance-plastics` are good names. Do not fix unrelated bugs or work on unrelated features in a "feature" branch - create a new one, switch to an existing one or commit directly to `master` if the changes are small enough.
-
-"Feature" branches may not be formatted properly. Formatting is required before merging into `master` or other branches.
-
-### Commits
-- Commits must leave the branch in a state that builds without compiler warnings (see below).
-- Changes should be grouped in commits semantically. Avoid committing many small related changes in sequence; if necessary, wait and accumulate them. Avoid committing unrelated changes together; if necessary, split staged changes into several commits. This should normally result in about 1-2 commits for a day's work.
-- Commit bulk changes (renaming, formatting, ...) separately. Don't ever commit whitespace changes outside formatting commits.
-- Message format:
-
-```
-Short description of changes
-<empty line>
-- Enumeration of changes
-  - Nest when appropriate
-- Use dashes only
-- List not needed for small commits
-```
-
-Example:
-
-```
-Changed packages for relations, renamed Face to ShapePart
-
-- Added BlockRelation as an abstract superclass to existing relations
-  - Must be given an absolute "up" direction before use
-- Moved AbsFace, AbsRelation and BlockRelation to .world.rels
-- Renamed Face to ShapePart to reduce confusion with AbsFace
-```
-
-- Only commit changes described in the commit message. Please double-check staged files before committing.
-- Avoid merge conflicts. Pull before committing.
-- Better sign commits than not. See: [git](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work), [GitHub](https://docs.github.com/en/github/authenticating-to-github/managing-commit-signature-verification).
-
-## Code
-
-### Warnings
-Make sure that all committed code contains no compiler warnings. This specifically includes unused imports, unused private members, missing `@Override`s and warnings related to generics.
-
-Warnings about unknown tokens in `@SuppressWarnings` are temporarily ignored. Please disable them in your IDE.
-
-### Code Style
-Formatting code is important.
-
-- The format is specified within the files inside `/templates_and_presets/eclipse_ide`. Import the specifications into Eclipse or IntelliJ IDEA and use the IDEs' format feature. Alternatively format the code manually in accordance with existing files.
-- Only use tabs for indentation. Never indent with spaces even when wrapping lines. This is to ensure that indentation does not break when tab width is different.
-- Don't use `I` prefix for interfaces (not `IDoable` but `Doable`).

-# Progressia Region File
-## Description
-The `.progressia_region` file type is used for all region files in the game Progressia. Each region file contains a cube of 16x16x16 chunks.
-## Header
-The header of the file is 16 400 bytes. Every file starts with the string byte sequence `\x50\x52\x4F\x47` (UTF-8 for `PROG`), followed with the three integer values of the region position, in region coordinates. After this, there is exactly 16KiB of space in the header, which stores the offsets to the chunks' data. This space holds an integer, 4 bytes, for each chunk in the region. The integer value starts at 0 for every chunk, and is changed to the location of the chunk data once created. These are indexed in order by flattening the 3D in-chunk coordinates into a number between 0 and 4095 according to the formula `offset = 256*x+ 16*y + z` for chunk at (x, y, z). To convert from this offset value to the offset in bytes, use `byte_offset = 16400 + 64*n`.
-## Sectors
-Sectors are what is used to store chunk data, and are not linear, but are followed until they reach an ending block. Each is 64 bytes, which is used in the header section to find the byte offset. Each sector starts with a identification byte, followed by the sector data.
-
- 0. Ending - This sector is empty, and marks the end of the chunk data (This may change in the future.
- 1. Data - This sector contains chunk data for a single chunk. The second byte of this sector contains a counter byte, which is a form of "checksum" to make sure that the program is reading the proper sectors in order. This starts at 0 for the first data sector and increments by one for each new data sector.
- 2. Partition Link - This sector only contains another offset value, which is where the next sector is. This allows for infinite chunk size, avoiding "chunk dupes" as were present in Minecraft without reverting any chunks.
- 3. Bulk Data - These would be used for many chunks in the same region that contain exactly the same data, e.g. all solid chunks underground. Exists so the program knows not to overwrite them, and just make new chunk data if modified. Not yet implemented.

-## Version and metadata
-
-### Version scheme
-
-Progressia builds are identified by four parameters: version, Git commit, Git branch and build ID.
-
-Versions roughly follow [semantic versioning](https://semver.org/spec/v2.0.0.html), with each version fitting the
-`MAJOR.MINOR.PATCH[-SUFFIX]` pattern. Depending on the build environment (see below), version is either "real" with
-no metadata (e.g. `0.43.2` or `1.2.1-beta`) or a dummy fallback with build metadata (e.g. `999.0.0-2021_07_23` or
-`999.0.0-WJ3`).
-
-### Version detection
-
-Build script considers three scenarios when determining the version:
-
-1. `version` project property is set explicitly. This may be done in a variety of ways, for example with command line
-argument `-Pversion=1.2.3`
-(see [Gradle docs](https://docs.gradle.org/current/userguide/build_environment.html#sec:project_properties))
-2. Local Git repository is found, and HEAD is tagged appropriately: version is the tag name with leading `v`
-stripped. Example: `v1.2.3` is version `1.2.3`
-3. Local Git repository is found, and some ancestor of HEAD is tagged appropriately: version is the tag name with
-leading `v` stripped and PATCH incremented by one. Example: `v1.2.3` is version `1.2.4`
-
-Tags not named like `vMAJOR.MINOR.PATCH[-SUFFIX]` are ignored for cases 2 and 3.
-
-In all other cases, a fallback dummy value is used for version, appended with build ID or current date.
-
-### Git metadata
-
-Git commit is determined from `GIT_COMMIT` environment variable if it exists, or the state of the local Git
-repository, if any, or `-`.
-
-Git branch is determined from `GIT_BRANCH` environment variable if it exists, or the state of the local Git
-repository, if any, or `-`.
-
-The names of the environment variables are picked to assist Jenkins builds.
-
-### Build ID
-
-Build ID uniquely identifies artifacts produced by automated build systems. Build ID must be provided explicitly; it
-is `-` unless specified otherwise.
-
-The proposed scheme for naming build IDs is `<builder><build-system><build attempt no.>`. For example, builds
-executed by WindCorp Jenkins suite have build IDs like `WJ3` or `WJ142`.
-
-Build ID may be set with `buildId` project property. This may be done in a variety of ways, for example with command
-line argument `-PbuildId=WJ3`
-(see [Gradle docs](https://docs.gradle.org/current/userguide/build_environment.html#sec:project_properties)).
-
-## Native libraries
-
-LWJGL uses native libraries. Build script declares platform-specific dependencies based on the set of target
-platforms, `project.ext.lwjgl.targets` (aka `lwjgl.targets`). These dependencies are added to `runtimeOnly`
-configuration.
-
-When this set is empty, the script selects natives for current platform. Otherwise, all platforms in the set are
-included.
-
-`lwjgl.targets` is populated automatically by packaging tasks and by `buildCrossPlatform`. To add extra targets,
-``requestXxxDependencies` tasks may be used.
-
-Target selection mechanism may be overridden with `forceTargets` project property. This may be done in a variety of
-ways, for example with command line argument `-PforceTargets=windows-x86,local`
-(see [Gradle docs](https://docs.gradle.org/current/userguide/build_environment.html#sec:project_properties)). The
-value is a comma-separated list of target architectures. `local` target will be replaced with the automatically
-detected current architecture.
-
-### Available targets
-
-| Name            | Task                         |
-|-----------------|------------------------------|
-| `linux`         | `requestLinuxDependencies`   |
-| `linux-arm32`   | `requestLinuxDependencies`   |
-| `linux-arm64`   | `requestLinuxDependencies`   |
-| `windows`       | `requestWindowsDependencies` |
-| `windows-arm64` | `requestWindowsDependencies` |
-| `windows-x86`   | `requestWindowsDependencies` |
-| `macos`         | `requestMacOSDependencies`   |
-| `macos-arm64`   | `requestMacOSDependencies`   |

- * An event bus optionally related to a {@link Component} that delivers input

- * <p>
- * By default, events are filtered by four checks before being delivered to each
- * listener:
- * <ol>
- * <li><em>Consumption check</em>: unless {@link Option#RECEIVE_CONSUMED
- * RECEIVE_CONSUMED} is set, events that are consumed will not be
- * delivered.</li>
- * <li><em>Hover check</em>: for certain event types (for example,
- * {@link WheelEvent} or {@link KeyEvent} that {@link KeyEvent#isMouse()
- * isMouse()}), the event will only be delivered if the component is hovered.
- * This check may be bypassed with option {@link Option#IGNORE_HOVER
- * IGNORE_HOVER} or made mandatory for all events with
- * {@link Option#REQUIRE_HOVER REQUIRE_HOVER}. Hover check automatically
- * succeeds if no component is provided.</li>
- * <li><em>Focus check</em>: for certain event types (for example,
- * {@link KeyEvent} that {@code !isMouse()}), the event will only be delivered
- * if the component has focus. This check may be bypassed with option
- * {@link Option#IGNORE_FOCUS IGNORE_FOCUS} or made mandatory for all events
- * with {@link Option#REQUIRE_FOCUS REQUIRE_FOCUS}. Focus check automatically
- * succeeds if no component is provided.</li>
- * <li><em>Type check</em>: events of type {@code E} are only delivered to
- * listeners registered with event type {@code T} if objects of type {@code E}
- * can be cast to {@code T}.</li>
- * </ol>
- * Checks 1-3 are bypassed when option {@link Option#ALWAYS ALWAYS} is
- * specified.
