我试图将XYZ从魔兽世界中的玩家转换为屏幕上的XY。 为此,我找到了播放器XYZ,相机矩阵,相机XYZ,Fov,NearClip,FarClip和CameraAspect。
我在游戏中找到的参数:
相机矩阵
[-0.79|-0.51|-0.34]
[ 0.55|-0.84| 0.00]
[-0.28|-0.18| 0.94]
玩家(目标)
X: -9468
Y: 46
Z: 56
相机
X: -9438
Y: 75
Z: 67
Fov: 1.57
FarClip: 28
NearClip: 28
CameraAspect: 3.7
如果计算了所有内容,则在使用1920 x 1080屏幕时显示X:774 Y:433。 一位朋友给了我这段代码,但我不明白:/

using SlimDX;

internal static IntPtr BaseAddress
{

{
var ptr = WoW.hook.Memory.Read<IntPtr>(Offsets.Camera.CameraPtr, true);
return WoW.hook.Memory.Read<IntPtr>(ptr + Offsets.Camera.CameraPtrOffset);
}
}
private static Offsets.CGCamera cam => WoW.hook.Memory.Read<Offsets.CGCamera>(BaseAddress);

var m = new Matrix();
m[0, 0] = BitConverter.ToSingle(bCamera, 0);

m[2, 0] = BitConverter.ToSingle(bCamera, 24);
m[2, 1] = BitConverter.ToSingle(bCamera, 28);
m[2, 2] = BitConverter.ToSingle(bCamera, 32);
return m;
}
}
public static Vector2 WorldToScreen(float x, float y, float z)
{
var Projection = Matrix.PerspectiveFovRH(FOV * 0.5f, Aspect, NearClip, FarClip);
var eye = new Vector3(X, Y, Z);
var lookAt = new Vector3(X + Matrix[0, 0], Y + Matrix[0, 1], Z + Matrix[0, 2]);
var up = new Vector3(0f, 0f, 1f);
var View = Matrix.LookAtRH(eye, lookAt, up);
var World = Matrix.Identity;
var WorldPosition = new Vector3(x, y, z);
var ScreenPosition = Vector3.Project(WorldPosition, 0f, 0f, WindowHelper.WindowWidth, WindowHelper.WindowHeight, NearClip, FarClip, World*View*Projection);
return new Vector2(ScreenPosition.X, ScreenPosition.Y-20f);
}
}
}
有人可以帮我解决数学问题,以及如何计算这些数据?
