[Help] Calc ptich and yaw for aimbot

[Zacherl]

Hey,

im trying to aim at the head of another player in crossfire, but I failed to calculate the correct values for pitch and yaw. This is my current try:

function GetCameraVectorFromViewMatrix(Device: IDirect3DDevice9): TD3DXVECTOR3;
var
  View: TD3DXMATRIX;
begin
  FillChar(Result, SizeOf(TD3DXVECTOR3), #0);
  if (Device.GetTransform(D3DTS_VIEW, View) = D3D_OK) then
  begin
    Result.x := - View._41;
      Result.y := - View._42;
      Result.z := - View._43;
  end;
end;

function GetDirectionVector(StartVector, EndVector: TD3DXVECTOR3): TD3DXVECTOR3;
var
  Diff: TD3DXVECTOR3;
begin
    D3DXVec3Subtract(Diff, EndVector, StartVector);
    D3DXVec3Normalize(Result, Diff);
end;

procedure MoveCroshairToPlayer(Device: IDirect3DDevice9;
  PlayerObject: PClientObject; Bone: LongInt);
var
  CameraVector,
  BoneVector,
  Direction: TD3DXVECTOR3;
begin
  CameraVector := GetCameraVectorFromViewMatrix(Device);
  if (not TransformBone(
    Device, PlayerObject, Bone, BoneVector, false)) then Exit;
  Direction := GetDirectionVector(BoneVector, CameraVector);

  LTClientShell^.PlayerClient^.Pitch := Direction.y;
  LTClientShell^.PlayerClient^.Yaw := Direction.x;
end;

TransformBone give me a world vector. Whats wrong with my code?

Best regards

Good Morning,

Firstable I have to say that Delphi sucks. Secondly this Code assumes that "LTClientShell^.PlayerClient^.Pitch" expects a cosine value of the vertical Angle, if it actually does, I don't see why it shouldn't be working. Yaw value seems to be a bit more complicated in terms of y AND z values.

I painted a picture to understand what you are doing and I cant spot a mistake.

In some games calling GetTransform don't always work as expected and may or may not work depending on when it is called. In CA for example I used to have to call it from begin scene and store it but after later updates I ended up simply grabbing local player view matrix from their class.

I suspect your running into something similar in CF.

But my bone ESP for example works fine using GetTransform()

2 problems

GetCameraVectorFromViewMatrix// not accurate cameracoords

LTClientShell^.PlayerClient^.Pitch := Direction.y;//both lines need more math or you will not aim properly
LTClientShell^.PlayerClient^.Yaw := Direction.x;

now that you know what the problem is, Im not gonna fix it cuz you never contribute and only ask for hand outs(every post).

Thats simply not true ..

#1: Easy way to get own index in player list:
Crossfire Information
#2: New pitch and yaw offsets:
Crossfire Information
#3: Struct for "no fall damage" and some other things (i never saw this before):
Crossfire Information

Im just learning. I dont know all the things. Thats the reason I ask. I spent one whole day for the aimbot but it still not works.

I tried this for example. But still crappy values:

DirectionVector := GetDirectionVector(CameraVector, BoneVector);
  Pitch := ArcTan(sqrt(DirectionVector.x * DirectionVector.x +
    DirectionVector.y * DirectionVector.y) / DirectionVector.z);
  Yaw := ArcTan(DirectionVector.x / (- DirectionVector.y));

FIrst problem is GetCameraVectorFromViewMatrix

its close to but not accurate, some values are off the range is to high and will severly mess up calculation.


@offtopic stuff sometimes learning is figuring it out on your own. :L

i spent 1 week for my first aimbot that i have ever done xD each day some hours
