# CustomBorder **Custom square world borders — fully independent of the vanilla Minecraft border.** Define named, persistent borders anywhere in your world. Players are kept inside with particles, pushback, and instant enforcement. Admins get fine-grained control over bypass, visibility, and settings — all at runtime, no restart needed. --- ## ✨ Features - **Square borders** — defined by a center point and a radius (half side-length in blocks) - **Full build-height wall** — the border spans 10,000 blocks vertically, covering the entire playable range - **Red particle wall** — appears as players approach; each player can set their own visibility distance - **Pushback mechanic** — players are pushed back toward the center when too close to the wall; can be toggled and tuned at runtime - **Instant movement enforcement** — movement events are intercepted in real-time, preventing any crossing without rubberbanding - **Teleport-back safety net** — if a player ends up outside anyway, they are immediately moved back in - **Admin bypass** — admins can toggle border enforcement for themselves with `/borderop` - **Admin `/tp` support** — command-sourced teleports always cross borders freely, so admins can move players to either side - **Per-player particle toggle** — admins (even with bypass active) can hide the particle wall for themselves - **Multiple borders** — define as many named borders as needed across any world - **Persistent storage** — all borders are saved to `borders.yml` and survive server restarts - **Fully independent** — does not touch or interact with the vanilla world border in any way - **Tab completion** — all commands support full tab completion including border names and argument suggestions --- ## 🗂️ Commands ### Player Commands *(Default: OP only — configurable via permissions)* | Command | Description | |---|---| | `/border help` | Shows all commands with explanations and your current settings | | `/border list` | Lists all active borders with name, world, center, and radius | | `/border info ` | Shows detailed info about a specific border | | `/border view` | Shows your current and the server-default visibility distance | | `/border view ` | Sets how far away you see the red particle wall (1–256 blocks) | | `/border view reset` | Resets your visibility distance to the server default | ### Admin Commands *(Requires `customborder.admin`)* | Command | Description | |---|---| | `/border create ` | Creates a square border centered on your current position | | `/border remove ` | Permanently deletes a border | | `/border pushback` | Shows current pushback status (enabled, distance, strength) | | `/border pushback on` | Enables the pushback mechanic globally | | `/border pushback off` | Disables the pushback mechanic globally | | `/border pushback distance ` | Sets how close players must be before getting pushed back | | `/border pushback strength ` | Sets the velocity force of the pushback (default: `1.2`) | | `/border particles on` | Shows the particle wall for yourself again | | `/border particles off` | Hides the particle wall for yourself (bypass-independent) | | `/borderop on` | Enables border bypass — you can freely cross all borders | | `/borderop off` | Disables border bypass — borders are enforced for you again | > **Note:** `/tp` (and any command-sourced teleport) always crosses borders freely, allowing admins to move players to either side without needing bypass. --- ## 🔐 Permissions | Permission | Description | Default | |---|---|---| | `customborder.use` | Use basic commands: `help`, `list`, `info`, `view` | `op` | | `customborder.admin` | Full control: create/remove borders, pushback settings, particles, bypass | `op` | --- ## ⚙️ Configuration All settings in `plugins/CustomBorder/config.yml`: ```yaml # Distance (in blocks) at which red particles become visible (server-wide default). # Each player can override this individually with /border view. particle-visibility-distance: 10.0 # Whether the pushback mechanic is active. Toggleable at runtime with /border pushback on|off. pushback-enabled: true # Distance (in blocks) from the wall at which players start getting pushed back. pushback-distance: 3.0 # Velocity strength of the pushback toward the border center. pushback-strength: 1.2 # How often (in ticks) the proximity check runs. 20 ticks = 1 second. check-interval: 5 # Number of particle points rendered per visible wall per check. particle-count: 8 # Height of the border wall in blocks. 10000 covers the full build range. border-height: 10000 ``` All pushback settings can be changed **at runtime** via commands — no need to edit the file or restart the server. Changes are saved immediately. --- ## 📖 How It Works 1. Stand at the center of where you want the border, then run `/border create `. - `radius` is the **half side-length**: a radius of `100` creates a **200 × 200** block area. - The border is **square**, axis-aligned, and centered on your exact position at the time of creation. 2. Players who approach within their visibility distance see a **red particle wall** along the border edge. 3. Within `pushback-distance` blocks of the wall, players are continuously **pushed back** toward the center. 4. If a player somehow ends up outside (e.g. via a plugin teleport), they are **immediately teleported back** to the nearest safe location inside. 5. **Admins** can use `/borderop on` to bypass all enforcement for themselves. When done, `/borderop off` re-enables it. 6. **Admins** can freely teleport players across borders using the standard `/tp` command. 7. **Every player** can customize how far away they see the particle wall with `/border view `, between 1 and 256 blocks. --- ## 💾 Data & Persistence Borders are stored in `plugins/CustomBorder/borders.yml` and loaded automatically on startup. The number of loaded borders is logged on enable: ``` [CustomBorder] Loaded 3 border(s) from storage. ``` Per-player settings (visibility distance, particles hidden, bypass) are **session-only** and reset on restart — this is intentional, as they are considered temporary preferences. --- ## 🔧 Requirements - **Server:** [Paper](https://papermc.io/) 1.21.1 or compatible fork - **Java:** 21 or newer --- ## 🐛 Issues & Source Found a bug or want to contribute?
