Jump/Walk/Run

[TheFadedOne]

So im currently working on a AutoHunting Function for 5165.
Im currently trying to work on the part that deals with auto movement

private void MoveTowards(Mob mob)
{
    // Check if the character is already in range of the target mob
    if (IsInRange(mob))
    {
        // The character is in range, so you can choose to attack the mob here
        AttackMob(mob);
        return; // Exit the method
    }
 

}

I was going to see if i can use
GC.MyChar.Loc.Jump(NX, NY);
GC.AddSend(Data);
And have the cords set to the mobs location but i dont fully understand the data structure

-		Data	{byte[40]}	byte[]
		[0]	32	byte
		[1]	0	byte
		[2]	26	byte
		[3]	39	byte
		[4]	235	byte
		[5]	70	byte
		[6]	15	byte
		[7]	0	byte
		[8]	211	byte
		[9]	1	byte
		[10]	216	byte
		[11]	1	byte
		[12]	64	byte
		[13]	134	byte
		[14]	105	byte
		[15]	91	byte
		[16]	137	byte
		[17]	0	byte
		[18]	0	byte
		[19]	0	byte
		[20]	219	byte
		[21]	1	byte
		[22]	219	byte
		[23]	1	byte
		[24]	0	byte
		[25]	0	byte
		[26]	0	byte
		[27]	0	byte
		[28]	255	byte
		[29]	255	byte
		[30]	255	byte
		[31]	255	byte
		[32]	84	byte
		[33]	81	byte
		[34]	67	byte
		[35]	108	byte
		[36]	105	byte
		[37]	101	byte
		[38]	110	byte
		[39]	116	byte

So i have manage to learn that
It's an array of bytes with a length of 40 bytes.
Each line represents one byte of data.
The numbers in square brackets represent the index or position of each byte in the array (0 to 39).
The hexadecimal values (e.g., 32, 0, 26) are the actual data stored in each byte.
The decimal values (e.g., 50, 0, 38) are the equivalent decimal representations of the hexadecimal values. but i have no idea how to make it think its sending the data to jump lol any help would be massively appreciated thank you

as far as i know the only way to change the position of your character from the server is to use teleportation of some kind - MsgAction Kickback, Set Location or by using that ninja skill (shadow step or smth?) You can probably abuse the two player emotes or whatever they are called, like holding hands, to actually do a jump initiated by the server too.

[TheFadedOne]

that shadow step method i eventually stumbled on
Currently im trying to make a function to move towards the mobs

private void MoveTowards(Mob mob)
{
    // Check if the character is already in range of the target mob
    if (IsInRange(mob, 10.0f))
    {
        // The character is in range, so you can choose to attack the mob here
        AttackMob(mob);
        return; // Exit the method
    }

    // Calculate the direction towards the target mob
    float angleTowardsMob = (float)MyMath.GetAngle(Loc.X, Loc.Y, mob.Loc.X, mob.Loc.Y);

    // Define movement offsets based on the calculated direction
    int offsetX = (int)(Math.Cos(angleTowardsMob) * 5); // Adjust the magnitude as needed
    int offsetY = (int)(Math.Sin(angleTowardsMob) * 5); // Adjust the magnitude as needed

    // Move the character using the calculated offsets based on its current location
    MoveCharacter(Loc.X + offsetX, Loc.Y + offsetY);
}

I recommend to debug your offsets and target positions, you spawn effects on the map to get visual feedback.

For walking in the right direction, towards a target, I use the following code

PHP Code:

ref readonly var pos = ref ntt.Get<PositionComponent>();
ref readonly var brn = ref ntt.Get<BrainComponent>();

var targetPos = NttWorld.GetEntity(brn.Target).Get<PositionComponent>().Position;
var dir = CoMath.GetRawDirection(targetPos, pos.Position);
var wlk = new WalkComponent(dir, false);
ntt.Set(ref wlk); 


GetRawDirection: (idk where I stole this from, i got frustrated after a while and just copy pasted this into my Math class..)

PHP Code:

public static byte GetRawDirection(Vector2 end, Vector2 start)
        {
            var dir = 0;

            var tan = new[] { -241, -41, 41, 241 };
            var deltaX = end.X - start.X;
            var deltaY = end.Y - start.Y;

            if (deltaX == 0)
                dir = deltaY > 0 ? 0 : 4;
            else if (deltaY == 0)
                dir = deltaX > 0 ? 6 : 2;
            else
            {
                var flag = Math.Abs(deltaX) / deltaX;

                deltaY *= 100 * flag;
                int i;
                for (i = 0; i < 4; i++)
                    tan[i] *= (int)Math.Abs(deltaX);

                for (i = 0; i < 3; i++)
                    if (deltaY >= tan[i] && deltaY < tan[i + 1])
                        break;

                deltaX = end.X - start.X;
                deltaY = end.Y - start.Y;

                if (deltaX > 0)
                {
                    switch (i)
                    {
                        case 0:
                            dir = 5;
                            break;
                        case 1:
                            dir = 6;
                            break;
                        case 2:
                            dir = 7;
                            break;
                        case 3:
                            dir = deltaY > 0 ? 0 : 4;
                            break;
                        default:
                            break;
                    }
                }
                else
                {
                    switch (i)
                    {
                        case 0:
                            dir = 1;
                            break;
                        case 1:
                            dir = 2;
                            break;
                        case 2:
                            dir = 3;
                            break;
                        case 3:
                            dir = deltaY > 0 ? 0 : 4;
                            break;
                        default:
                            break;
                    }
                }
            }

            dir += 8;
            return (byte)dir;
        } 


This method returns the direction byte you put into MsgWalk

EDIT:
You probably dont use vectors, so here's a conversion function

PHP Code:

internal static Vector2 DirectionToVector(Direction direction)
        {
            return direction switch
            {
                Direction.North => new Vector2(0, 1),
                Direction.NorthEast => new Vector2(1, 1),
                Direction.East => new Vector2(1, 0),
                Direction.SouthEast => new Vector2(1, -1),
                Direction.South => new Vector2(0, -1),
                Direction.SouthWest => new Vector2(-1, -1),
                Direction.West => new Vector2(-1, 0),
                Direction.NorthWest => new Vector2(-1, 1),
                _ => throw new ArgumentException($"Invalid direction: {direction}"),
            };
        } 


sorry, i gotta go to work now, but if you want to find points to *jump* to, instead of multiplying the magnitude, you might want to look into the scent-sword/fast-blade DDA Line algo to get the points on the line and chose one to jump to instead.

Oh come on dude, stop using the 5165 source, I'm telling you, that has a lot's of bugs and the main bug on that source is duplicate which is a non-stop bug. If I were you continue to use the 5517 you get. If you want I can give you a 5517 source that has autohunt.

What's the method for duping?

I'm not sure, however there are numerous techniques to get this duplicate item to work. As far as I know, most Filipino players are attempting to re-create the dupe in a different manner. You know American/Europeans are easily to scam in p-server because they are lazy.



But here are some list that dupe work:
1. Warehouse Withdraw/Deposit
2. ItemDropping
3. Pick Item at the same time with other character.
4. Vending (Don't know how it works but this is the latest I gather).
5. GoldDrop (Not sure how it's done but saw some players dropping golds).
6. Trade (not sure about this) but it something like a connection about gold and gambling npc.

So i have patched all of the methods that I'm aware of, and always seek people to test exploits on my private development server. so your welcome to test. but everything you listed there can easily be fixed, im not lazy i know enough myself. but if i need more complex methods i have people to help me learn. im not going to abandon 5165 as i know with alot of patience it will be a real nice server.

[Soulfly25]

We'll that would be great everything can be fixed anyway. I just noticed that most of 5165 server using impulse based source is running only a few months due to this exploit. Oh, if you want some client modification to your 5165 server, I have a friend that goods at client modification, and he is in China.

[32212019]

I have a ncos with autohunt but its 5095 version. We dont use it. We used different source now. He is right though ncos has alot of dup we have figured it out. You can have it if you want. But its still ncos though.

[TheFadedOne]

Surely if you dupe an item it would have the same UID? just make a check for them uids and destroy the items if found with same IDS?

We aren't sure but I bet they already did that and yet it's still exist. The last time I heard with the fixed on the vending dupe was it involve the Mac Address on each PC.

[TheFadedOne]

Interesting, Well if you know someone who knows how to do the exploit, I'm willing to work with you to create the patch and we can share it.

I would love too but it's a never ending exploit. Also it's rare nowadays to get a loyalty player who will tell you when they found exploit/bug most of it they abused to ruin the server.

[TheFadedOne]

I just cant agree with a never ending exploit, Anything can be patched
