| - | ===== Rotations ===== | ||
| - | Unity uses 3 rotation systems. | ||
| - | |||
| - | - Euler Angers - rotation about x, y, z axis | ||
| - | - Angle Axis - A normalized Vector3 representing the axis about which to rotate by float angle amount | ||
| - | - Quaternions | ||
| - | |||
| - | |||
| - | <code c#> | ||
| - | // Convert from Quaternion to Euler: | ||
| - | Vector3 inEuler = quaternionRotation.eulerAngles; | ||
| - | |||
| - | // Convert Euler to Quaternion | ||
| - | Quaternion inQuaternion = Quaternion.Euler(inEuler); | ||
| - | |||
| - | // To Angle-Axis | ||
| - | Quaternion randomQuaternion = Random.rotation; | ||
| - | float angle; | ||
| - | Vector3 axis; | ||
| - | |||
| - | randomQuaternion.ToAngleAxis(out angle, out axis); | ||
| - | |||
| - | // And back | ||
| - | Quaternion rotation = Quaternion.AngleAxis(angle, | ||
