Should you use Quaternions or Euler Angles in Unity? The Euler Angles property is a convenient way to set and read an object’s rotation in a format that’s easier to read and work with than Quaternions. Like this: transform.rotation = Quaternion.Euler(new Vector3(0,10,0)) Or, instead of working in Quaternions, you can convert a Vector 3 Euler Angle rotation into a Quaternion. Like this: // Copies another object's rotation This means that if you want to set the rotation property directly, you’ll need to use a Quaternion value instead. So, when using lerAngles, you’re essentially setting and reading a converted value. The rotation value you see in the Inspector is the real Quaternion rotation converted to a Vector 3 value, an Euler Angle, which is rotation expressed as an XYZ value for pitch, yaw and roll. ![]() Instead, I set a different property, Euler Angles.īehind the scenes, Unity calculates rotation using Quaternions, meaning that the rotation property of an object is not actually a Vector 3, it’s a Quaternion. Notice, however, that I didn’t set the rotation property directly like I might do when setting an object’s position, for example. Rotational vector 3 values describe a degree of rotation around each of the 3 axes, X Y and Z. In this example, I’ve set the rotation of the object to 10 degrees around the Y Axis. Like this: Vector3 newRotation = new Vector3(0, 10, 0) Like this: Vector3 newPosition = new Vector3(0, 10, 0) Īn object’s rotation can also be set directly via its Transform, In the same way that a game object’s position in the world can be set using its Transform component… ![]() In the Inspector, you’ll see an object’s rotation as a Vector 3 value: Rotation in Unity typically works by specifying an amount of rotation in degrees around the X, Y or Z axis of an object. Which means that once you’re used to the basics of rotating an object in Unity, you’ll find it easier to use some of the more advanced rotation features that Unity offers. While there are a lot of different options available to you, many of them work in similar ways. While others work best for certain tasks. Some methods are simple, some are more complex. There are a lot of different ways to rotate an object in Unity. How to Rotate a Rigidbody with the mouse.How to rotate an object over time (Lerp & Slerp).How to rotate an object towards another.How to rotate the camera around an object in Unity.How to rotate an object around a point in Unity. ![]() Which means that knowing the right method to use, in order to get the effect that you want, can be a little confusing at first.īut don’t worry, because in this in-depth guide I’ll show you all of the different methods for rotating an object in Unity, and the best time to use each of them, step by step. Just as there are many different ways to move an object, there are many different ways to rotate one too. Rotating an object in Unity can be very straightforward.
