If you want to rotate a vector you should construct what is known as a rotation matrix. Rotation in 2D Say you want to rotate a vector or a point by θ, then trigonometry states that the new coordinates are To demo this, let’s take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, … Read more
You can use transform.rotation like this: OR You can use transform.Rotate like this: Documentation for Quaternion Documentation for transform.rotation Example for Rotating screen with accelerometer input: If you want to rotate the object to a specific angle use: This will rotate 90 degrees around the x axis.
