# PaperUI A Java/Kotlin library for creating user interfaces on Paper servers ## How to use Either: Add PaperUI as a plugin to your Paper server and add PaperUI to your dependencies in `plugin.yml` or `paper-plugin.yml`\ Or: Include PaperUI in your plugin ### Maven ```xml DiruptioPublic https://repo.diruptio.de/repository/maven-public ``` ```xml de.fabiexe PaperUI VERSION ``` ### Gradle ```kotlin repositories { maven("https://repo.diruptio.de/repository/maven-public") } ``` ```kotlin dependencies { compileOnly("de.fabiexe:PaperUI:VERSION") } ``` ## DialogUI A dialog user interface can have properties/inputs, buttons and action buttons. Example:\ OrderPizzaUI

### Kotlin ```kotlin enum class PizzaType { MARGHERITA, FUNGHI, PROSCIUTTO } fun create(audience: Audience) = DialogUI(audience).apply { title("Order a Pizza") val type by enumProperty("Type", PizzaType::class.java) val extraCheese by booleanProperty("Add Extra Cheese") val radius by doubleProperty("Radius (cm)", 15.0, 20.0) val amount by integerProperty("Amount", 1, 10, 1) val address by stringProperty("Address") actionButton("Order") { var pizza = "$type with radius ${radius}cm" if (extraCheese.get()) { pizza += " with extra cheese" } val message = "We will deliver $amount $pizza to $address" audience.sendMessage(Component.text(message)) } actionButton("Cancel") } ``` ```kotlin fun doSomething() { create(player).open() } ``` ### Java (short) ```java public class OrderDrugsUI { public static DialogUI create(@NotNull Audience audience) { DialogUI ui = new DialogUI<>(audience); ui.title("Order drugs"); Property type = ui.enumProperty("Type", DrugType.class); Property dosis = ui.doubleProperty("Dosis (%)", 50, 120, 100); Property amount = ui.integerProperty("Amount", 1, 10); Property address = ui.stringProperty("Address"); ui.actionButton("Order", () -> { String drug = type.get() + " with dosis " + dosis.get() + "%"; String message = "We will deliver " + amount.get() + " " + drug + " to " + address.get(); audience.sendMessage(Component.text(message)); }); ui.actionButton("Cancel"); return ui; } private enum DrugType { CANNABIS, COCAINE, HEROIN, FENTANYL } } ``` ```java public void doSomething() { OrderDrugsUI.create(player).open(); } ``` ### Java (long) ```java public class OrderCoffeeUI extends DialogUI { private final Property type; private final Property size; private final Property milk; private final Property amount; private final Property address; public OrderCoffeeUI(@NotNull Audience audience) { super(audience); title("Order a Coffee"); type = enumProperty("Type", CoffeeType.class); size = doubleProperty("Size (liters)", 0.25, 1, 0.33); milk = booleanProperty("Add milk"); amount = integerProperty("Amount", 1, 10); address = stringProperty("Address"); actionButton("Order", this::order); actionButton("Cancel"); } private void order() { String coffee = type.get() + " with size " + size.get() + "l"; if (milk.get()) { coffee += " with milk"; } String message = "We will deliver " + amount.get() + " " + coffee + " to " + address.get(); audience.sendMessage(Component.text(message)); } private enum CoffeeType { COFFEE, ESPRESSO, CHOCOLATE_COFFEE, DOUBLE_CHOCOLATE_COFFEE } } ``` ```java public void doSomething() { new OrderCoffeUI(player).open(); } ```
