Thread: Need help with increasing arrays? :)

So ive packed 116 data and everything is okay anims, gfx and npc's! but when i add obj.dat/idx and repack index items, i can login into the game although i get this error

Code:

Exception in thread "Thread-1" java.lang.ArrayIndexOutOfBoundsException: 41058
	at ItemDef.forID(ItemDef.java:397)
	at ItemDef.getSprite(ItemDef.java:914)
	at Client.drawInterface(Client.java:11762)
	at Client.drawInterface(Client.java:11680)
	at Client.draw3dScreen(Client.java:12849)
	at Client.method146(Client.java:16701)
	at Client.drawGameScreen(Client.java:11455)
	at Client.processDrawing(Client.java:12750)
	at RSApplet.run(RSApplet.java:189)

Now i know its it saying that its sending some more than it holds right?

Line 397 Itemdef.forID

Code:

		stream.currentOffset = streamIndices[i];

So i got to this

Code:

public static void unpackConfig(StreamLoader archive) {
		ItemDef.stream = new Stream(archive.getDataForName("obj.dat"));
		Stream stream = new Stream(archive.getDataForName("obj.idx"));
		totalItems = stream.readUnsignedWord() + 21;
		streamIndices = new int[totalItems + 5687];
		int i = 2;

		int i1;
		for (i1 = 0; i1 < totalItems - 21; ++i1) {
			streamIndices[i1] = i;
			i += stream.readUnsignedWord();
		}

		cache = new ItemDef[10];

		for (i1 = 0; i1 < 10; ++i1) {
			cache[i1] = new ItemDef();
		}

Then noticed this

Code:

streamIndices = new int[totalItems + 5687];

Is this what is causing the problem? If so what do i change it to? and if not can someone please point me in the right direction.
Thanks


EDIT- 20 views and not one person can point in the right direction? i am looking at java tutorials on index out of bounds but its not helping
