[Question] Vehicle rotation | help with this?

[Leonardo]

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:

00:00 incar testing

00:20 unoccupied testing

00:00 airplane testing



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.
