Description

The askForInput function is a utility method that allows you to prompt a player for input in a GUI. It adds the player to a list of players waiting for input, closes their current inventory, and sends them a message requesting input. The function returns a CompletableFuture<String> that will be completed with the player's response once they have entered it.

The function uses a CompletableFuture to handle the asynchronous nature of player input. It continuously checks for the player's response in a loop until it is received, sleeping for 1 millisecond between each check. Once the response is received, the CompletableFuture is completed with the response.

How to use

You can use the askForInput function to prompt a player for input and receive the response as a CompletableFuture<String>. The function takes two parameters:

player: The Player object representing the player you want to prompt.
request: The message you want to display to the player as the input request.

Here is an example of how to use the askForInput function in Kotlin:

val inv = kGui.builder(player)
                .setTitle("Input Test")
                .setSize(3)
                .addButton(Alignment.CENTER, GuiButton().setItemStack(
                    KItemStack.builder()
                        .setName("&aClick me to input")
                        .setMaterial(Material.PAPER)
                        .build()
                ).setOnClick { builder, player ->
                    askForInput(player, "Enter your name:")
                                .thenAccept { response ->
                        player.sendMessage("You entered: $response")
                    }
                })
                .build()
                
player.openInventory(inv)

In this example, we create a GUI with a button that, when clicked, prompts the player to enter their name. The response is then displayed to the player in a chat message.

Summary

The askForInput function is a useful utility method for handling player input in a GUI. It allows you to prompt players for input and receive their responses asynchronously, making it easy to create interactive and engaging user interfaces in your Minecraft plugin or mod.
