My rotation is weird

Question

I want my object to choose random direction, rotate to it and then follow it for a while. After this repeat it all again. Here is my code for choosing direction

private void ChooseDirection() {
    // create a random angle from 0.0 to 360.0, Remap is a simple function for it
    float angle = Utils.Remap (Random.value, 0.0f, 1.0f, 0.0f, 360.0f);
    transform.Rotate (Vector3.up, angle);
    print (angle + " : " + transform.rotation.eulerAngles.y);

}

The code above produces the following output to the console

38.12973 : 38.12972

283.771 : 321.9007

295.227 : 257.1267

142.9637 : 40.09043

178.7077 : 218.7981

126.3595 : 345.1576

347.749 : 332.9065

250.1977 : 223.1042

243.5038 : 106.608

252.1878 : 358.7958

20.00817 : 18.804

As you can see the actual rotation angle is not the randomly chosen angle. As the result my object doesn't face the direction in which it's moving.

You aren't setting the rotation. You are rotating. (i.e. Adding the chosen rotation to the transform's existing rotation.) — Abion47
I changed my code, now the angles match. I am still having the problem that the object is facing wrong direction. I will try to set angle to known values such as 0, 10, 45, 90 ... and see how it moves — sasha199568
I found my problem. In Translate function I used transform.forward. I should have used Vector3.forward. My bad, you could not have solved my problem, because I didn't post my moving code — sasha199568

You are currently just rotating the object, not setting its rotation. Instead of transform.Rotate(...) you should be using:

transform.rotation = Quaternion.Euler(0, 0, angle);
