This camera smoothes out rotation around the y-axis and height.
|
|
Horizontal Distance to the target is always fixed.
|
|
|
|
There are many different ways to smooth the rotation but doing it this way gives you a lot of control over how the camera behaves.
|
|
|
|
For every of those smoothed values we calculate the wanted value and the current value.
|
|
Then we smooth it using the Lerp function.
|
|
Then we apply the smoothed values to the transform's position.
