[help] about the mount/movement
this is the video
this is my char/entity.cs
Code:
public bool Move(Enums.ConquerAngle Direction)
{
ushort _X = X, _Y = Y;
Facing = Direction;
sbyte xi = 0, yi = 0;
switch (Direction)
{
case Enums.ConquerAngle.North: xi = -1; yi = -1; break;
case Enums.ConquerAngle.South: xi = 1; yi = 1; break;
case Enums.ConquerAngle.East: xi = 1; yi = -1; break;
case Enums.ConquerAngle.West: xi = -1; yi = 1; break;
case Enums.ConquerAngle.NorthWest: xi = -1; break;
case Enums.ConquerAngle.SouthWest: yi = 1; break;
case Enums.ConquerAngle.NorthEast: yi = -1; break;
case Enums.ConquerAngle.SouthEast: xi = 1; break;
}
_X = (ushort)(X + xi);
_Y = (ushort)(Y + yi);
Game.Map Map = null;
if (ServerBase.Kernel.Maps.TryGetValue(MapID, out Map))
{
if (Map.Floor[_X, _Y, MapObjType, this])
{
if (MapObjType == MapObjectType.Monster)
{
Map.Floor[_X, _Y, MapObjType, this] = false;
Map.Floor[X, Y, MapObjType, this] = true;
}
X = _X;
Y = _Y;
return true;
}
else
{
if (Mode == Enums.Mode.None)
{
if (EntityFlag != EntityFlag.Monster)
Teleport(MapID, X, Y);
else
return false;
}
}
}
else
{
if (EntityFlag != EntityFlag.Monster)
Teleport(MapID, X, Y);
else
return false;
}
return true;
}
This is my Packet
Code:
static void PlayerGroundMovment(GroundMovement groundMovement, Client.GameState client)
if (client.Entity.ContainsFlag(Update.Flags.Ride))
client.Entity.Vigor -= 1;
// client.Entity.PX = client.Entity.X;
//client.Entity.PY = client.Entity.Y;*/
if (groundMovement.Direction > Enums.ConquerAngle.South)
{
groundMovement.Direction = (JudeProject.Game.Enums.ConquerAngle)((byte)groundMovement.Direction % 8);
}
client.Entity.Move(groundMovement.Direction);
if (groundMovement.GroundMovementType == 9)
{
client.Entity.Move(groundMovement.Direction);
}
client.SendScreen(groundMovement, true);
client.Screen.Reload(groundMovement);
My Groundmovement
Code:
namespace JudeProject.Network.GamePackets
{
using JudeProject;
using JudeProject.Client;
using JudeProject.Game;
using JudeProject.Interfaces;
using JudeProject.Network;
using System;
public class GroundMovement : Writer, IPacket
{
private byte[] Buffer;
public const uint Run = 1;
public const uint TwoCoordonates = 9;
public const uint Walk = 0;
public GroundMovement(bool CreateInstance)
{
if (CreateInstance)
{
this.Buffer = new byte[32];
Writer.WriteUInt32(24, 0, this.Buffer);
Writer.WriteUInt32(10005, 2, this.Buffer);
}
}
public void Deserialize(byte[] buffer)
{
this.Buffer = buffer;
}
public void Send(GameState client)
{
client.Send(this.Buffer);
}
public byte[] ToArray()
{
return this.Buffer;
}
public Enums.ConquerAngle Direction
{
get
{
return (Enums.ConquerAngle)((byte)(this.Buffer[4] % 8));
}
set
{
this.Buffer[4] = (byte)value;
}
}
public uint GroundMovementType
{
get
{
return JudeProject.BitConverter.ToUInt32(this.Buffer, 12);
}
set
{
Writer.WriteUInt32(value, 12, this.Buffer);
}
}
public uint MapID
{
get
{
return JudeProject.BitConverter.ToUInt32(this.Buffer, 20);
}
set
{
Writer.WriteUInt32(value, 20, this.Buffer);
}
}
public uint TimeStamp
{
get
{
return JudeProject.BitConverter.ToUInt32(this.Buffer, 0x10);
}
set
{
Writer.WriteUInt32(value, 0x10, this.Buffer);
}
}
public uint UID
{
get
{
return JudeProject.BitConverter.ToUInt32(this.Buffer, 8);
}
set
{
Writer.WriteUInt32(value, 8, this.Buffer);
}
}
}
}
my movement angle
Code:
public enum ConquerAngle : byte
{
East = 5,
North = 3,
NorthEast = 4,
NorthWest = 2,
South = 7,
SouthEast = 6,
SouthWest = 0,
West = 1
}
how do i fix my walking problem? does anyone know how? thanks
my bad for duplicating threads.

Your walk code is incorrect for steed mode.
Code:
dir = (int) receive.Direction % 24;
newX = user.X + Common.DeltaMountX[dir];
newY = user.Y + Common.DeltaMountY[dir];
Where delta mount x/y are
Code:
DeltaMountX = new sbyte[] { 0, -2, -2, -2, 0, 2, 2, 2, 1, 0, -2, 0, 1, 0, 2, 0, 0, -2, 0, -1, 0, 2, 0, 1, 0 };
DeltaMountY = new sbyte[] { 2, 2, 0, -2, -2, -2, 0, 2, 2, 0, -1, 0, -2, 0, 1, 0, 0, 1, 0, -2, 0, -1, 0, 2, 0 };

I explained one way to handle walking. You need to re-write your walking handler to behave in a similar fashion.

It might not help with your case, but it might help the majority of members wondering where Chris's logic comes from. Below was the diagram I created to figure it out (back in the day). It might also help the next person who wants to help you locate where the code is in your source to change. Cheers.

it still doesnt work..

Dalaran Sewer Mount arena (Aq 40 opening mount)

Well, you cant use any mounts in dalaran arena, except Black Qiraji Resonating Crystal. I know not much people have it, but still it is not intended to be able to mount in this arena, so i posted it there) Btw, you still can get the Scarab Lord title and mount, there are several servers, where gates are not open yet, all new servers where transfer is closed for first 3 months have their gates closed, so you can make the scepter on your server and then transfer to another server with closed...
