A3D_QuaternionToEuler

Turn a quaternion, such as one from GetVehicleRotationQuat, into the rotation of an object.

native bool:A3D_QuaternionToEuler(
    Float:w,
    Float:x,
    Float:y,
    Float:z,
    &Float:rx,
    &Float:ry,
    &Float:rz
);

Parameters

Parameter	Description
Float:w	Real part of the quaternion.
Float:x	Part of the X axis.
Float:y	Part of the Y axis.
Float:z	Part of the Z axis.
&Float:rx	Rotation on the X axis.
&Float:ry	Rotation on the Y axis.
&Float:rz	Rotation on the Z axis.

Returns

• true when the rotation was written.

Remarks

The reverse of A3D_EulerToQuaternion. It turns the rotation of a vehicle into the rotation of an object, on every axis, where the facing angle of a vehicle only gives the heading.

Example

Leaves a wreck turned exactly as the vehicle was, on a slope too.

stock LeaveWreck(vehicleid) {
    new
        Float:x,
        Float:y,
        Float:z,
        Float:w,
        Float:qx,
        Float:qy,
        Float:qz,
        Float:rx,
        Float:ry,
        Float:rz
    ;

    GetVehiclePos(vehicleid, x, y, z);
    GetVehicleRotationQuat(vehicleid, w, qx, qy, qz);
    A3D_QuaternionToEuler(w, qx, qy, qz, rx, ry, rz);

    return CreateObject(3593, x, y, z, rx, ry, rz);
}
