Quaternion Converter
Convert GetVehicleRotationQuat angles to XYZ!

What is it?
Quaternion Converter is a simple include which provides functions to convert a quaternion set (most commonly used in GetVehicleRotationQuat) to XYZ. (yaw, pitch and roll)

How do I use it?
Copy the include to your includes directory.
Include the "quaternion.inc" file in any scripts which you would like to use these functions in. (with "#include <quaternion>")

What am I allowed to do with it?

Function list

Код:

stock QuaternionToYawPitchRoll(Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z,&Float:x,&Float:y,&Float:z)

Takes the quaternion values specified by quat_w, quat_x, quat_y and quat_z, then converts them into roll, pitch and yaw (respectively) and saves them into the variables specified by x, y and z.

Код:

stock QuaternionGetRoll(Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z,&Float:roll)

Takes the quaternion values specified by quat_w, quat_x, quat_y and quat_z, then converts them into roll (respectively) and saves them into the variables specified by roll.

Код:

stock QuaternionGetPitch(Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z,&Float:pitch)

Takes the quaternion values specified by quat_w, quat_x, quat_y and quat_z, then converts them into pitch and saves them into the variables specified by pitch.

Код:

stock QuaternionGetYaw(Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z,&Float:yaw)

Takes the quaternion values specified by quat_w, quat_x, quat_y and quat_z, then converts them into yaw and saves them into the variable specified by yaw.

must live simply!!!

PHP код:

stock GetVehicleRotation(vehicleid,&Float:x,&Float:y,&Float:z) {
    new Float:quat_w,Float:quat_x,Float:quat_y,Float:quat_z;
    GetVehicleRotationQuat(vehicleid,quat_w,quat_x,quat_y,quat_z);
    x = atan2(2*((quat_x*quat_y)+(quat_w+quat_z)),(quat_w*quat_w)+(quat_x*quat_x)-(quat_y*quat_y)-(quat_z*quat_z));
    y = atan2(2*((quat_y*quat_z)+(quat_w*quat_x)),(quat_w*quat_w)-(quat_x*quat_x)-(quat_y*quat_y)+(quat_z*quat_z));
    z = asin(-2*((quat_x*quat_z)+(quat_w*quat_y)));
    return 1;
}

Good Job!

[gesior7]

Your code, DANGER1979 works really nice with SA-MP objects. = )

[Babul]

i believe, heres a multiplication needed instead of addidion: (quat_w+quat_z)

Код:

x = atan2(2*((quat_x*quat_y)+(quat_w*quat_z)),(quat_w*quat_w)+(quat_x*quat_x)-(quat_y*quat_y)-(quat_z*quat_z));

[Falco-Ger]

can u add something for this?
https://sampforum.blast.hk/showthread.php?tid=292795

anyway, megaupload is down

edit: requesting answer

[[Vector]]

Sorry for my ignorance, but what can I do with this?

[MP2]

Find out the angles (X+Y) of a vehicle.

[Falco-Ger]

can anyone post the code here since megaupload is down?

what's the matter?
does anyone have that or a similar code then post it here please.
should just contain the functions from the original include and be working

thank you very much
