# PlayerWaypoints ### Server-side mod for adding custom waypoints to the Locator Bar using Polymer's Virtual-Entity API Allows for creation of waypoints per-world as well as per-player, and can be attached like any other virtual entity.

How to use:

### Global Waypoints: ###### _{Global waypoints will be sent to all players in the world the waypoint is in.} `PlayerWaypointManager.addGlobalWaypoint(serverWorld, pos, id) -> WaypointElement` `PlayerWaypointManager.addGlobalWaypoint(serverWorld, waypointElement) -> WaypointElement` ##### Removing a waypoint: `PlayerWaypointManager.removeGlobalWaypoint(serverWorld, waypointElement) -> void` ### Per-Player Waypoints: ###### _{Per-Player waypoints will be sent to the player if they are in the same world.

`PlayerWaypointManager.addPlayerWaypoint(player, serverWorld, pos, id) -> WaypointElement`
`PlayerWaypointManager.addPlayerWaypoint(player, serverWorld, waypointElement) -> WaypointElement`

##### Removing a waypoint:

`PlayerWaypointManager.removePlayerWaypoint(player, serverWorld, waypointElement) -> void`

## Using with Polymer
The waypoints are built upon [Polymer's Virtual Entity Element](https://polymer.pb4.eu/latest/polymer-virtual-entity/basics/), so you can add a `WaypointElement` the same way you would any other element.

## The WaypointElement Class
WaypointElements are the basic way of representing a waypoint for the Locator Bar

` WaypointElement(ServerWorld, Identifier)`

### Config
`WaypointElement::getConfig(ServerPlayerEntity)` : Gets the Waypoint's client-bound config

`WaypointElement::setColor(int)` : Sets the color - _{^{RGB

`WaypointElement::setStyle(RegistryKey)` : Sets the Waypoint's style _{^{[See: Minecraft Wiki / Waypoint Style](https://minecraft.wiki/w/Waypoint_style)}}
^{- Note for Waypoint Styles: Distance calculation isn't working, so it will always show the "furthest" sprite. This is unfortunately a bug.}
^{- However, you can override `getConfig(...)` and change the style manually depending on the distance using `getDistanceTo`.

### Positioning and transmission
`WaypointElement::setWaypointTransmitRange(double)` : Sets the range the player can see the waypoint. The waypoint will stop transmitting after this distance.

`WaypointElement::setPosition(Vec3d)` : Sets the position of the waypoint.

^{- You can also use `setOffset(...)` for the same result.

`WaypointElement::isPlayerInRange(PlayerEntity) -> boolean` : Whether the waypoint should transmit to this player or not.

`WaypointElement::getObservers() -> Set` : Gets all players which this Waypoint is currently transmitting to

`WaypointElement::getDistanceTo(PlayerEntity)`
`WaypointElement::getSquaredDistanceTo(PlayerEntity` Get distance to a given player from the Waypoint

### Waypoint Holograms (WIP)
WaypointElements can have Holograms attached, to display information to the user.

By default, holograms will display directly above the Waypoint.

This is very experimental, and may not work. I'd recommend just building holograms separately.

This can be overridden using `getHologramElementPosition`

`WaypointElement::setHologram(List)` : Sets the Hologram of the Waypoint using MarkerElements

`WaypointElement::setHologram(List)` : Sets the hologram of the Waypoint

`WaypointElement::removeHologram(HologramData)` : Removes a Hologram from the Waypoint.

`getHologramElementPosition(Vec3d origin, int line, HologramData) -> Vec3d` : Gets the position of a Hologram element

^{Defaults to `origin.offset(Direction.UP, (line * 0.25f))`

## Other utilities

`SVPlayerWaypoints.getHolderForWorld(ServerWorld)` : Gets a holder at exactly [0,0,0]}}}}}}
