Hey, I'm pretty new to the community just started learning my way around OSBot.
Here's a script I made in a day just to test the API out, releasing it here so other people might learn from it.
Not a great script but it does its job. (Feedback is appreciated)

import org.osbot.rs07.api.Inventory;
import org.osbot.rs07.api.model.NPC;
import org.osbot.rs07.api.ui.RS2Widget;
import org.osbot.rs07.script.Script;
import org.osbot.rs07.script.ScriptManifest;

import javax.swing.*;
import java.awt.*;
