A3D_EulerToQuaternion

Turn the rotation of an object into a quaternion, in the order of GetVehicleRotationQuat.

native bool:A3D_EulerToQuaternion(
    Float:rx,
    Float:ry,
    Float:rz,
    &Float:w,
    &Float:x,
    &Float:y,
    &Float:z
);

Parameters

Parameter	Description
Float:rx	Rotation on the X axis.
Float:ry	Rotation on the Y axis.
Float:rz	Rotation on the Z axis.
&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.

Returns

• true when the quaternion was written.

Remarks

The angles are those of SetObjectRot. The quaternion is the one GetVehicleRotationQuat would give for a vehicle turned the same way, in the same order: w first, then x, y and z. ColAndreas writes w last, so swap the order when porting.

Example

Tells whether a vehicle stands turned like an object, slopes included.

stock bool:IsTurnedLike(vehicleid, Float:rx, Float:ry, Float:rz) {
    new
        Float:w,
        Float:x,
        Float:y,
        Float:z,
        Float:vehicleW,
        Float:vehicleX,
        Float:vehicleY,
        Float:vehicleZ
    ;

    A3D_EulerToQuaternion(rx, ry, rz, w, x, y, z);
    GetVehicleRotationQuat(vehicleid, vehicleW, vehicleX, vehicleY, vehicleZ);

    return floatabs(w * vehicleW + x * vehicleX + y * vehicleY + z * vehicleZ) > 0.99;
}
