Coping data between scenes and loading new level (U2017/2018)

If would like to have the same lighting between scenes, I would need to copy the settings.

Also if player would pick up coins in one level, amount of coin-data and scripts would need to transfer to another level/scene.

I'm following Roll a ball tutorial https://unity3d.com/learn/tutorials/s/roll-ball-tutorial)
and I would like to know what is the most efficient way to do this for U2017.3/2018 ?

I've found tutorial from 2016
but people in comments said that this crashed in newer version of Unity and inventory keeps resetting.

Is there some official way explained how to do that in some efficient way ?

 

just look up the features that are outdated on the Unity Api learn page thing.

here watch this guy, he wil show you how to look up functions

also, avoid tutorials that are over a year old, for that reason, that they are outdated.. (actually the best way to learn, I think, is these outdated tutorials.. look up the function on Unity Learn, usualy there is the perfect code snippet (that works) right there on the page.

try this tutorial series, one of the best that I have found, and it is current
