Question Vehicle rotation | help with this?

I was wondering if you need help with this, because it might help.

What I have done has been a function to obtain the euler rotation from a matrix.

In the unoccupied sync, the SA-MP client sends the right and front vectors to the server, so it is necessary to build the up vector to obtain the euler rotation, so I also made a function for that.

To test it, I converted the C ++ code to Pawn, this would be the result:

Part of the Pawn code would look like this:

Code:
forward test_timer();

public test_timer()

{

    if(test_vehicleid != INVALID_VEHICLE_ID)

    {

        new mat[MATRIX];

        new pos[VECTOR];

        new rot[VECTOR];

        mat = GetVehicleMatrix(test_vehicleid);

        rot = Matrix_GetRotation(mat, Vector(-9999.0, -9999.0, -9999.0));

        pos = Matrix_Multiply3x3(mat, Vector(0.0, 12.0, 2.0));

        pos[X] += mat[POS][X];

        pos[Y] += mat[POS][Y];

        pos[Z] += mat[POS][Z];

        SetObjectPos(test_objectid, pos[X], pos[Y], pos[Z]);

        SetObjectRot(test_objectid, rot[X], rot[Y], rot[Z]);

    }

}

I would not know who to talk to to discuss this issue, so I created this post. If you are interested in this, you can send me a private and I will send you the source code in C ++, including the Pawn code.

Note: Sorry for my English, I speak Spanish and I have translated this with google translate.
