This is for the Underwall Tunnel at the Grand Exchange.

In your ObjectHandler, you will want to place these two methods (preferably under HandleOption5, somewhere):

	public static void climbTunnel(final Player player, final boolean goingIn) {
		if (player.getBoneDelay() > Utils.currentTimeMillis())
			return;
		player.addBoneDelay(150);
		if (!goingIn) {
			player.addWalkSteps(3144, 3514, 0, false);
			player.setNextWorldTile(new WorldTile(3143, 3514, 0));
			player.setNextAnimation(new Animation(2589));
		} else {
			player.addWalkSteps(3138, 3516, 0, false);
			player.setNextWorldTile(new WorldTile(3139, 3516, 0));
			player.setNextAnimation(new Animation(2589));
		}
		player.getPackets().sendGameMessage("Climb into the tunnel...");
		WorldTasksManager.schedule(new WorldTask() {
			@Override
			public void run() {
				if (!goingIn) {
					player.addBoneDelay(3000); //5sec-2sec=3sec
					walkTunnel(player, false);
				} else {
					player.addBoneDelay(3000); //5sec-2sec=3sec
					walkTunnel(player, true);
				}
				stop();
			}
		}, 2);
	}

	public static void walkTunnel(final Player player, final boolean goingIn) {
		if (!goingIn) {
			player.setNextAnimation(new Animation(2591));
			player.setNextWorldTile(new WorldTile(3139, 3516, 0));
		} else {
			player.setNextAnimation(new Animation(2591));
			player.setNextWorldTile(new WorldTile(3143, 3514, 0));
		}
		player.getPackets().sendGameMessage((goingIn) ? "...and end up inside the Grand Exchange" : "...and end up outside the Grand Exchange.");
		WorldTasksManager.schedule(new WorldTask() {
			@Override
			public void run() {
				if (!goingIn) {
					player.addWalkSteps(3138, 3516, 0, false);
				} else {
					player.addWalkSteps(3144, 3514, 0, false);
				}
				stop();
			}
		});
	}

Then, in your HandleOption1 method, inside ObjectHandler, add this:

				} else if (id == 9311 && object.getX() == 3139 && object.getY() == 3516) {
					climbTunnel(player, true); // GE Tunnel outside to inside
				} else if (id == 9312 && object.getX() == 3143 && object.getY() == 3514) {
					climbTunnel(player, false); // GE Tunnel inside to outside

simple implementation but appreciate the contribution

thanks man, will use this on my server!

Really good implementation!

thanks!

thanks
