Build Minecraft Plugins The Easy Way



NextLib v1.0.2
NextLib 1.0.2

Short Description

NextLib 1.0.2 adds an extensible GUI action registry that allows third-party plugins to register their own click handlers via the API. The update includes thread-safe logging and improved diagnostics when loading YAML menus.

Major changes:
  • Added the thread-safe Actions.registerAction registry, which allows you to map identifiers and arguments from YAML to GuiAction factories.
  • The functional interface of the GuiActionFactory is presented, which simplifies the creation of actions to which the GUIManager and the argument string are passed.
  • GuiLoader now builds actions through the registry and logs unknown identifiers, which makes debugging configurations easier.

How to use

Code (Java):
import io.github.chi2l3s.nextlib.api.gui.Actions ;
import io.github.chi2l3s.nextlib.api.gui.GuiManager ;
import org.bukkit.Location ;
import org.bukkit.plugin.java.JavaPlugin ;

public final class CustomActionsPlugin extends JavaPlugin {
    @Override
    public void onLoad ( ) {
// Registration can take place in onLoad or OnEnable before loading the YAML menu.
    }

    @Override
    public void onEnable ( ) {
        Actions. registerAction ( "teleport", (manager, args ) -> {
            String [ ] parts = args. split ( " " ) ;
            if (parts. length < 3 ) {
                throw new IllegalArgumentException ( "Usage: teleport <x> <y> <z>" ) ;
            }

            double x = Double. parseDouble (parts [ 0 ] ) ;
            double y = Double. parseDouble (parts [ 1 ] ) ;
            double z = Double. parseDouble (parts [ 2 ] ) ;

            return player -> player. teleport ( new Location (player. getWorld ( ), x, y, z ) ) ;
        } ) ;
    }
}

After registering an action, you can call it in the YAML menu.:

Code (YAML):
items:
  tp-button
:
    material
: ENDER_PEARL
    slot
: 13
    name
: "&bTeleport"
on_left_click
:
     - "teleport 0 80 0"

If you try to use a non-existent action in the menu, a warning will be sent to the plugin's log indicating the problematic element and the type of click.
