Thread: [508] NPC Drops

Great job I will add you to credits

This isn't npcdrops.cfg/xml, this is just a very simple way of adding drops, but takes up a lot more space, isn't as efficient and such. Not the best way of doing it, here's how to implement the npcdrops.cfg file, from my older source, (xml is actually better), if you can find a tutorial for that. But here's what you need to do for npcdrops.cfg:


Go to Engine.java and find "getPlayerCount()" or "rebuildNPCs()", underneath add the following (may need some converting for your source), this works on any codeusa source.

Spoiler for Engine.java npcdrops:

Code:

	public static NPCDrops NpcDrops[] = new NPCDrops[10000];
	public static double[][] drops = new double[9000][150]; // 45 drops per NPC
	public static int[] dropCount = new int[9000];

	public static void dropNPCItems(int NPCID, NPC npc, Player killer) {
		try {
			int totalDrops = dropCount[NPCID] / 3;
			if (totalDrops > 0) {
				// Random roller = new Random();
				for (int i = 0; i < dropCount[NPCID]; i += 3) {
					double roll = Math.random() * 100;
					if (roll <= drops[NPCID][i + 2]) {
						if ((drops[NPCID] != null) && (npc != null))
							items.createGroundItem((int) drops[NPCID][i], (int) drops[NPCID][i + 1], npc.absX,
									npc.absY, npc.heightLevel, killer.username);
					}
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

	}
	public static int GetNPCDropArrayID(int NPCID, int DropType) {
		for (int i = 0; i < 10000; i++) {
			if (NpcDrops[i] != null) {
				if ((NpcDrops[i].npcId == NPCID)
						&& (NpcDrops[i].DropType == DropType)) {
					return i;
				}
			}
		}
		return -1;
	}
	public void loadNPCDrops() {
		String line = "";
		String token = "";
		String token2 = "";
		String token2_2 = "";
		String[] token3 = new String[10];
		boolean EndOfFile = false;
		BufferedReader characterfile = null;
		try {
			characterfile = new BufferedReader(new FileReader("./data/npcs/npcdrops.cfg"));
		} catch (FileNotFoundException fileex) {
			System.out.println("[LOAD NPC DROPS] File not found.");
			return;
		}
		try {
			line = characterfile.readLine();
		} catch (IOException ioexception) {
			System.out.println("[LOAD NPC DROPS] Error loading file.");
			return;
		}
		while ((EndOfFile == false) && (line != null)) {
			line = line.trim();
			int spot = line.indexOf("=");
			if (spot > -1) {
				token = line.substring(0, spot);
				token = token.trim();
				token2 = line.substring(spot + 1);
				token2 = token2.trim();
				token2_2 = token2.replaceAll("\t\t", "\t");
				token2_2 = token2_2.replaceAll("\t\t", "\t");
				token2_2 = token2_2.replaceAll("\t\t", "\t");
				token2_2 = token2_2.replaceAll("\t\t", "\t");
				token2_2 = token2_2.replaceAll("\t\t", "\t");
				token3 = token2_2.split("\t");
				if (token.equals("npcdrop")) {
					if (Integer.parseInt(token3[0]) <= -1)
						continue;
					drops[Integer.parseInt(token3[0])][dropCount[Integer.parseInt(token3[0])]] = Integer
							.parseInt(token3[1]);
					drops[Integer.parseInt(token3[0])][dropCount[Integer
					                                             .parseInt(token3[0])] + 1] = Integer
					                                             .parseInt(token3[2]);
					drops[Integer.parseInt(token3[0])][dropCount[Integer
					                                             .parseInt(token3[0])] + 2] = Integer
					                                             .parseInt(token3[3]);
					dropCount[Integer.parseInt(token3[0])] += 3;
				}
			}
			try {
				line = characterfile.readLine();
			} catch (IOException ioexception1) {
				EndOfFile = true;
			}
		}
		try {
			characterfile.close();
		} catch (IOException ioexception) { }
	}

EDIT: in NPC.java, find your appendNpcDrops() method, add at the bottom of the method:

Engine.dropNPCItems(npcType, this, p); // Drops items from the npcdrops.cfg file

Next add this file in build->data->npcs
npcdrops.cfg

That is your npcdrops.cfg file, add all your drops in there, i've added a line at the top of the file on how to format. DONT USE ANY SPACES, ONLY TABS

If you run into any problems, let me know, i might have left out some things not sure, just threw this together in a few mins.

Goodluck.

Great Job
