OSBuddyHealthBar.java:

Code:

package org.nova.kshan.content.interfaces;

import org.nova.Constants;
import org.nova.cache.loaders.WidgetDef;
import org.nova.game.entity.Entity;
import org.nova.game.npc.NPC;
import org.nova.game.player.Player;

/**
 * Handles the overlay of the OSBuddy Health Bar.
 * 
 * @author K-Shan

 */
public class OSBuddyHealthBar {

	/**
	 * Represents the widget ID which contains the OSBuddy health bar.
	 */
	public static final int WIDGET = 1156;

	/**
	 * 
	 * @param player
	 * @param entity
	 * @param hp
	 */
	public static void showBar(Player player, Entity entity, int hp, int damage) {
		if(entity != null && entity instanceof Player)
			showPlayerHealth(player, ((Player) entity),damage);
		else
			showNPCHealth(player, ((NPC) entity), damage);	
		if(hp < 1) {
			player.doAfterDelay(1.5, () -> { closeBar(player); });
			player.getData().getRuntimeData().remove("osbuddy_health");
			player.getData().getRuntimeData().remove("osbuddy_last_hp");
			return;
		}
	}

	/**
	 * 
	 * @param p
	 * @param npc
	 * @param hp
	 */
	public static void showNPCHealth(Player p, NPC npc, int damage) {
		if (!p.interfaces().containsInterface(WIDGET))
			p.interfaces().sendTab(2, WIDGET);
		p.packets().sendString(npc.getName(), WIDGET, 3);
		p.packets().sendString(npc.getHitpoints()+"/"+npc.getMaxHitpoints(), WIDGET, 7);
		double calculated = 161.0 * ((double) npc.getHitpoints() / npc.getMaxHitpoints());
		int total = (int) Math.floor(calculated);
		if(Constants.DEVELOPER_MODE && p.getRights() > 1)
			p.sm("Percentage of health bar: "+calculated+": To display: "+total);
		int green = 6;
		int yellow = 5;
		WidgetDef greenBar = WidgetDef.getComponent(WIDGET, green);
		WidgetDef yellowBar = WidgetDef.getComponent(WIDGET, yellow);
		p.packets().changeWCSize(WIDGET, green, npc.getHitpoints() < 1 ? 0 : total, greenBar.baseHeight);
                // add animation here
		p.doAfterDelay(0.600, () -> { 
			p.packets().changeWCSize(WIDGET, yellow, npc.getHitpoints() < 1 ? 0 : total, yellowBar.baseHeight);
		});
	}

	/**
	 * 
	 * @param p
	 * @param other
	 * @param hp
	 */
	private static void showPlayerHealth(Player p, Player other, int damage) {
		if (!p.interfaces().containsInterface(WIDGET))
			p.interfaces().sendTab(2, WIDGET);
		p.packets().sendString(other.getDisplayName(), WIDGET, 3);
		p.packets().sendString(other.getHitpoints()+"/"+other.getMaxHitpoints(), WIDGET, 7);
		double calculated = 161.0 * ((double) other.getHitpoints() / other.getMaxHitpoints());
		int total = (int) Math.floor(calculated);
		if(Constants.DEVELOPER_MODE && p.getRights() > 1)
			p.sm("Percentage of health bar: "+calculated+": To display: "+total);
		int green = 6;
		int yellow = 5;
		WidgetDef greenBar = WidgetDef.getComponent(WIDGET, green);
		WidgetDef yellowBar = WidgetDef.getComponent(WIDGET, yellow);
		p.packets().changeWCSize(WIDGET, green, other.getHitpoints() < 1 ? 0 : total, greenBar.baseHeight);
                // add animation here
		p.doAfterDelay(0.600, () -> { 
			p.packets().changeWCSize(WIDGET, yellow, other.getHitpoints() < 1 ? 0 : total, yellowBar.baseHeight);
		});
	}

	/**
	 * 
	 * @param player
	 */
	private static void closeBar(Player player) {
		player.packets().closeInterface(2);

	}


}

... where:
"changeWCSize" is a method which adjusts the size of a widget component,
"doAfterDelay" executes whatever is inside of the curly braces after the specified delay, in seconds.

If you have any questions, feel free to ask.
