Spoiler for click here fella:

NOTE: the reason u see 0 coins displayed in the interface, is because when u send a negative amount to the client it displays it as 0, and the reason its negative is because of overflow - feel free to read more about it here: [Only registered and activated users can see links. ]
However this is easily fixable, and theres several ways to go about it.

Also, the interface is nothing special, i just used some sprites for it that i had in my cache.

Code:

Client:

Code:

	private static void dropSimulator(TextDrawingArea[] tda) {
		
		RSInterface main = addInterface(57392);
		
		addSpriteLoader(57393, 1079);
		addSpriteLoader(57394, 1098);
		
		addHoverButtonWSpriteLoader(57650, 1095, 147, 32, "Set simulation amount", -1, 57651, 1);
		addHoveredImageWSpriteLoader(57651, 1096, 147, 32, 57652);
		
		addHoverButtonWSpriteLoader(57653, 1095, 147, 32, "Simulate drops", -1, 57654, 1);
		addHoveredImageWSpriteLoader(57654, 1096, 147, 32, 57655);
		
		addText(57656, "Set simulation amount", tda, 1, ColorConstants.WHITE);
		addText(57657, "Simulate drops", tda, 1, ColorConstants.WHITE);
		addText(57658, "Drop Simulator", tda, 2, ColorConstants.SKY_BLUE);
		
		addCloseButtonSmall(57659, 57660, 57661);
		
		main.totalChildren(13);
		main.child(0, 57393, 10, 10);
		main.child(1, 57394, 140, 105);
		main.child(2, 57399, 140, 110);
		main.child(3, 57410, 20, 50);
		
		main.child(4, 57650, 162, 65);
		main.child(5, 57651, 162, 65);
		
		main.child(6, 57653, 322, 65);
		main.child(7, 57654, 322, 65);
		
		main.child(8, 57656, 175, 72);
		main.child(9, 57657, 350, 72);
		
		main.child(10, 57658, 220, 20);
		
		main.child(11, 57659, 475, 19);
		main.child(12, 57660, 475, 19);
		
		RSInterface loot = addTabInterface(57399);
		
		loot.width = 330;
		loot.height = 190;
		loot.scrollMax = 400;
		
		addToItemGroup(57400, 8, 60, 9, 8, true, new String[] {null, null, null, null, null});
		
		loot.totalChildren(1);
		loot.child(0, 57400, 9, 7);
		
		RSInterface npcs = addTabInterface(57410);
		
		npcs.width = 100;
		npcs.height = 255;
		npcs.scrollMax = 2500;
		
		npcs.totalChildren(150);
		
		int id = 57420;
		int childStart = 0;
		int yPos = 7;
		
		for(int i = 0; i < 150; i++) {
			addHoverableText(id, "", "Select", tda, 0, false, true, 100, ColorConstants.ORANGE, ColorConstants.WHITE);
			npcs.child(childStart, id, 0, yPos);
			id++;
			childStart++;
			yPos += 13;
		}

Button stuff:

Code:

			return true;
		}

/**
		 * Drop simulator
		 */

		case -7886:
			if (!player.getClickDelay().elapsed(3000)) {
				player.sendMessage("@[email protected] wait atleast 3 seconds between each simulation");
				return;
			} else {
				player.getPacketSender().sendEnterInputPrompt("How many would you like to simulate drops for?");
				player.setInputHandling(new SetDropSimulationAmount());
				player.getClickDelay().reset();
			}
			break;

		case -7883:
			player.getDropSimulator().simulateDrops();
			break;

this also accounts for drop rate(since i had it on my server) so feel free to delete it if u don't want it

Credit to: [Only registered and activated users can see links. ] as i used a part of his method that he wrote for picking the drops.

can u give me your addToItemGroup method?

okay nice thank you

and which drop System are u using? im too stupid to rewrite it to mine xd

Ruses but half of it is rewritten

still Need your addToItemGroup method, would be nice

Algorithm kinda slow, it'd probably cause lag on other players who were also running simulators. Cool non the less nice release
