Oh, mai, freaking god. Er... After all your work they have to try to add this xd. Really, thanks so much. Wish I know how to do that. Argh Want to lean coding.

U should put 'coding example included' or something, I feel like it would attract more people :p

Its fine, it was partly for myself to challenge myself and stop being bored xD. Also I wanted to show that it was more than possible :P

Cool idea (ocean current pun intended), but it would probably lag the server to the point where it's borderline unplayable.

Well, I think that the code that @Ironraptor3 made is planned to be eficient (pls correct me if I'm wrong). I can't discuss this a lot, but if there are no particles involved I think this won't make the server unplayable.

Kid holy crap, I work for an hour to show that you don't need to check points OR use the distance formula, and you still skip through and say that it would cause lag :/

Seriously tho, any lag players would experience would be from boats themselves, which suck anyway.

This is soooo.......

GENIUS!

The thing that I like about this is that the currents will be even more realistic as you regen mana slower in water, hindering your abilitiy to "Fight" the current. Though I wonder, as I am no coding expert what would happen if you will ride a boat through the current? Will it push you in weird directions? For example if the current is going forward, and you come from the side on a boat, what happens?

No, they will just be slower. Make the boat to be pushed in certain direction it's too difficult. Of course, going in the right direction will make you go faster.

Nope, already had that covered in the code. You are pushed tangent to the direction it flows (The direction at that point in the current, in vector form)

Wha...OMG!

Well, GG man!

I really hope this gets added, because it is not only possible, it would make the game feel more realistic.

it wouldn't be terrible unless an entire server was in boats (Never seen that one before)

This was a few years back, organized by yours truly.

^ old Nemract!!!

We all went for a swim in volcano island :_)

Anyway the point i'm trying to make is that the servers need to be prepared for anything. I love the idea of currents but it's no fun if it crashes the server if we try to do something like this!

Hello Wynncraftians!
In my opinion this idea can improve a lot the server
so read carefully!
:saltedhappy:

--)Ocean Currents(--

General Information:
What are they?
An Ocean current is a continuous, directed and superficial movement of sea water.

What utilities will they have?

When you have to go to the Mage Island, when you have to travel to the Dead Island, or just you have to go to Selchar adn you don't have any TP scrolls, is always a bit tedious to travel. So, what basically will they do is to make you travel faster! The mechanics will be more complicated of course.

Explaining The Mechanics:
Map Distribution:
View attachment 60771
Directions:
Every Current will have a specific direction. For example, if you want to go to Nemract to Selchar, you will have to catch the blue current. Going against the current direction will give you Slowness 4, so you will practically not move. On the other hand, going at the same direction of the current, will give you instead a huge speed bonus.
Cold and Hot Currents:
You can see that there are 2 types of Currents: Hot and Cold ones. Cold currents go slower than hot ones, but they are used for traveling, as you can see in the image (50%+ speed). Hot ones, however, are used for returning or exploring (Example: Mage Island-Half Moon Island- Durums Island), but they go FASTER (100%+).

The Code:
Yea, the code for doing this is done, so now we can perfectly tell that this is possible! Everything on this code section was written by @Ironraptor3 , he did an awesome job! ^^

Code:

public class Main extends JavaPlugin implements Listener {
    //And obviously, anyone with an interest in making plugins can always talk to me if you want help
    public static Plugin plugin;
    World w = null;
    public static final double speed = .3; //again, changeable, or able to be stored in another class and altered
    //Testing speed at 1 was pretty violent when opposing the current

    //Add a config file to save current info in between sessions, too lazy to do that for just an example

    @Override
    public void onEnable() {
        plugin = this;

                                removing.remove(b);//boats despawn within 10 seconds of being placed
                                b.remove();

}

The principal objective if this idea is to make ocean adventures funnier. With this, you will have to plan a bit your route, not only breaking your finger with the W key.
Each current will have a name, just like "Great Wynn Current" or "Dead Current".

Edit 1: Currents no longer force you to go to it's direction.
Edit 2: We have the code for doing this now :P
Edit 3: Improved Code pages. Last 3
Edit 4: WATER PUSH YOU AGAIN! No lag involved

THE GAME
Can you find the missing island? :D

Thanks for reading!
Hope you have liked my idea and

To make ocean currents FUNNIER

To make ocean currents more fun

Heck I wouldn't even mind if it were funner, but funnier, seriously?

This was a few years back, organized by yours truly.

^ old Nemract!!!

We all went for a swim in volcano island :_)

Anyway the point i'm trying to make is that the servers need to be prepared for anything. I love the idea of currents but it's no fun if it crashes the server if we try to do something like this!

Aw... Well, maybe with a bit of Improvisation we can make that boats don't make the server crash. But, anyway, this happends maybe 1 time a year or 2, I think it's quite worth it to add this feature >:D
