MoveByPacket Function
Hello,
I find it difficult to do the MoveByPacket function (in SendPackets) in C # :
Code:
public enum PacketMoveType { Flying = 0x61, Jumping = 0x28, Running = 0x21, Walking = 0x20, Swimming = 0xA1 };
public void moveByPackets(Coordinates Destination, PacketMoveType MoveType)
{
float Speed;
short MoveCounter;
Coordinates currentCoords = new Coordinates(InfoCharacter.CharacterCoordinates);
switch (MoveType)
{
case PacketMoveType.Flying:
Speed = InfoCharacter.CharacterSpeedFly;
break;
case PacketMoveType.Jumping:
Speed = InfoCharacter.CharacterSpeedRun;
break;
case PacketMoveType.Running:
Speed = InfoCharacter.CharacterSpeedRun;
break;
case PacketMoveType.Walking:
Speed = InfoCharacter.CharacterSpeedWalk;
break;
case PacketMoveType.Swimming:
Speed = InfoCharacter.CharacterSpeedSwim;
break;
default:
Speed = InfoCharacter.CharacterSpeedRun;
break;
}
short TimeInterval = 1000;
float TimeNeeded = Destination.Range3D(currentCoords) / Speed;
float dX = ((Destination.X - currentCoords.X) / TimeNeeded) * TimeInterval / 1000;
float dY = ((Destination.Y - currentCoords.Y) / TimeNeeded) * TimeInterval / 1000;
float dZ = ((Destination.Z - currentCoords.Z) / TimeNeeded) * TimeInterval / 1000;
if (Speed > 0)
{
while (TimeNeeded > (float)TimeInterval / 1000)
{
currentCoords.X += dX;
currentCoords.Y += dY;
currentCoords.Z += dZ;
MoveCounter = InfoCharacter.CharacterMoveCounter;
MoveTo(currentCoords.X, currentCoords.Y, currentCoords.Z, TimeInterval, Speed, 0, MoveCounter);
MoveCounter++;
InfoCharacter.CharacterMoveCounter = MoveCounter;
TimeNeeded -= (float)TimeInterval / 1000;
Thread.Sleep(TimeInterval);
}
if (TimeNeeded > 0)
{
MoveCounter = InfoCharacter.CharacterMoveCounter;
currentCoords.X += dX * TimeNeeded;
currentCoords.Y += dY * TimeNeeded;
currentCoords.Z += dZ * TimeNeeded;
MoveStop(currentCoords.X, currentCoords.Y, currentCoords.Z, (short)(TimeNeeded * 1000), Speed, (byte)MoveType, MoveCounter, 0);
MoveCounter++;
InfoCharacter.CharacterMoveCounter = MoveCounter;
}
}

SendPacket(moveStopAddressRev, packetSize);
}
BaseAddress = 12817100
CharStruct = 52
(Short) InfoCharacter.CharacterMoveCounter = ((BaseAddress + CharStruct) + 2564)
(Float) InfoCharacter.CharacterSpeedFly = ((BaseAddress + CharStruct) + 1292)
(Float) InfoCharacter.CharacterSpeedRun = ((BaseAddress + CharStruct) + 1284)
(Float) InfoCharacter.CharacterSpeedWalk = ((BaseAddress + CharStruct) + 1280)
(Float) InfoCharacter.CharacterSpeedSwim = ((BaseAddress + CharStruct) + 1288)
(Coordinates) InfoCharacter.CharacterCoordinates And Destination are used like this:
Code:
public class Coordinates
{
public float X;
public float Y;
public float Z;
public float DisplayX { get { return (float)Math.Round((X + 4000) / 10, 1); } }
public float DisplayY { get { return (float)Math.Round((Y + 5500) / 10, 1); } }
public float DisplayZ { get { return (float)Math.Round(Z / 10, 1); } }
public Coordinates()
{
X = 0;
Y = 0;
Z = 0;
}
public Coordinates(float x, float y, float z)
{
this.X = x;
this.Y = y;
this.Z = z;
}
public Coordinates(Coordinates Coords)
{
this.X = Coords.X;
this.Y = Coords.Y;
this.Z = Coords.Z;
}
public float Range3D(Coordinates Dest)
{
float dX = X - Dest.X;
float dY = Y - Dest.Y;
float dZ = Z - Dest.Z;
return (float)Math.Round(Math.Sqrt(dX * dX + dY * dY + dZ * dZ), 1);
}
public float Range2D(Coordinates Dest)
{
float dX = X - Dest.X;
float dZ = Z - Dest.Z;
return (float)Math.Sqrt(dX * dX + dZ * dZ);
}
}
The problem is that the MoveByPackets does nothing. I thought i had the wrong offset on SendPacket_Adress and SendPacket_Adress, but not since i use functions SelectTarget, RegularAttack, PickUpItem they work.
If you have an idea of the problem or if you have any questions do not hesitate to post.

Are you updating your moveCounter and player coordinates properly after every packet sent(manually changing their values in memory to the new values)?

Thank ank you for your answer Interest07 
I'm too stupid  , it's obvious, I add the update values moveCounter and player send coordinates to each request packet, like this:
Code:
public enum PacketMoveType { Flying = 0x61, Jumping = 0x28, Running = 0x21, Walking = 0x20, Swimming = 0xA1 };
public void moveByPackets(Coordinates Destination, PacketMoveType MoveType)
{
float Speed;
short MoveCounter;
Coordinates currentCoords = new Coordinates(InfoCharacter.CharacterCoordinates);
switch (MoveType)
{
case PacketMoveType.Flying:
Speed = InfoCharacter.CharacterSpeedFly;
break;
case PacketMoveType.Jumping:
Speed = InfoCharacter.CharacterSpeedRun;
break;
case PacketMoveType.Running:
Speed = InfoCharacter.CharacterSpeedRun;
break;
case PacketMoveType.Walking:
Speed = InfoCharacter.CharacterSpeedWalk;
break;
case PacketMoveType.Swimming:
Speed = InfoCharacter.CharacterSpeedSwim;
break;
default:
Speed = InfoCharacter.CharacterSpeedRun;
break;
}
short TimeInterval = 1000;
float TimeNeeded = Destination.Range3D(currentCoords) / Speed;
float dX = ((Destination.X - currentCoords.X) / TimeNeeded) * TimeInterval / 1000;
float dY = ((Destination.Y - currentCoords.Y) / TimeNeeded) * TimeInterval / 1000;
float dZ = ((Destination.Z - currentCoords.Z) / TimeNeeded) * TimeInterval / 1000;
if (Speed > 0)
{
while (TimeNeeded > (float)TimeInterval / 1000)
{
MoveCounter = InfoCharacter.CharacterMoveCounter;
currentCoords.X += dX;
currentCoords.Y += dY;
currentCoords.Z += dZ;
MoveTo(currentCoords.X, currentCoords.Y, currentCoords.Z, TimeInterval, Speed, 0, MoveCounter);
InfoCharacter.CharacterCoordinates = currentCoords;
MoveCounter++;
InfoCharacter.CharacterMoveCounter = MoveCounter;
TimeNeeded -= (float)TimeInterval / 1000;
Thread.Sleep(TimeInterval);
}
if (TimeNeeded > 0)
{
MoveCounter = InfoCharacter.CharacterMoveCounter;
currentCoords.X += dX * TimeNeeded;
currentCoords.Y += dY * TimeNeeded;
currentCoords.Z += dZ * TimeNeeded;
MoveStop(currentCoords.X, currentCoords.Y, currentCoords.Z, (short)(TimeNeeded * 1000), Speed, (byte)MoveType, MoveCounter, 0);
InfoCharacter.CharacterCoordinates = currentCoords;
MoveCounter++;
InfoCharacter.CharacterMoveCounter = MoveCounter;
}
}
}
(Coordinates) InfoCharacter.CharacterCoordinates = currentCoords;
MemoryWriteFloat(CharacterBase + 60, InfoCharacter.CharacterCoordinates.X);
MemoryWriteFloat(CharacterBase + 68, InfoCharacter.CharacterCoordinates.Y);
MemoryWriteFloat(CharacterBase + 64, InfoCharacter.CharacterCoordinates.Z);
(Short) InfoCharacter.CharacterMoveCounter = MoveCounter;
MemoryWriteShort(CharacterBase + 2564), InfoCharacter.CharacterMoveCounter);
But it does not change much, except that the camera view moves as change of displacement but not the character. 
I still make a mistake somewhere but I do not know where.

Well obviously you won't see a smooth movement, except for your camera - but others do.

I'm just looking to move the character by MoveByPacket function .... Maybe it's just a dream

Nobody has a suggestion to the problem?
I think the structure of the packets is bad
Code:
private byte[] movePkt = new byte[]
{
0x00, 0x00, //Header
0x00, 0x00, 0x00, 0x00, //x coord
0x00, 0x00, 0x00, 0x00, //y coord
0x00, 0x00, 0x00, 0x00, //z coord
0x00, 0x00, 0x00, 0x00, //x coord
0x00, 0x00, 0x00, 0x00, //y coord
0x00, 0x00, 0x00, 0x00, //z coord
0x00, 0x00, //interval
0x00, 0x00, //speed
0x00, //moveType
0x00, 0x00 //counter
};
But how can i check if the structure is good?

I cannot realy help you but i got a question to that topic aswell.
Like Interest said in an other post (  ) the structure is like this:
0000<X><Y><Z><X><Y><Z><interval><speed><moveType>< counter>
I would be interest in just performing a simple "jump". I tried to use this structure with current coordinates and 28 as movetype...but i dont know the speed and counter so i guess thats why its not working.
Does anyone know how to do a simple "jump" just by sending a packet like this?

If you mean an actual ingame jump, it's actually several movement packets and it's prolly easier to do by calling the jump function. If you just mean going 'speed' meters up into the air, you will definitely need the counter or the packet will never be processed. Speed is generally just 5 m/s when unbuffed.

I just mean an ingame jump - so u say there is a simple packet to call the jump function or do u mean something else?

I'm saying the exact opposite, there's an easy function to call, but it's tough with sending packets.

I actually hate the jump function. You need 3 static addresses, and action struct. It's a ***** to maintain, and it's not very stable when I tested it. Packets would be the way to go.

It's more a thing of maths (or rather physics) than programming.
What you need to do is calculate points on trajectory path for a projectile.
It's not the easiest thing to do, however real world examples can be greatly simplified for PW, since you can exclude air drag, wind and some other forces associated with projectiles in real world.
What you should take into account is gravity (PW uses roughly same gravitational acceleration as objects on Earth, which is about 9.8m/ss).
Points on trajectory path should be calculated for each time T where T2-T1 (or delta T) is about 500ms, since that's how often motion packets are sent.
You will also need to know initial speed of a projectile (character) and the angle at which it is thrown (jumps).
I should also point out, that my tests with packets for free falling objects indicate that while there is no terminal velocity for falling objects, server is very accurate regarding speed an object is allowed to reach in free fall as well as acceleration.
For this reason I find using gravitational acceleration of less than 9.8m/ss is beneficial for higher lags (150-250ms), for example I had good results with 9.0-9.4 m/ss, depending on lag.
This is something to be weary of when calculating second part of trajectory (free fall part).
It is entirely possible that you can further simplify trajectory and still be ok with server, but that's down to trial and error.
Check below wiki link and research form there.

Thanks for your input =)
I will try this out a bit tomorrow - i also think there is a different in gravity if u are in an instance like frost or outside in worldmap.
If i manage to get something to work i will repost it.
