50 Tips for Working with Unity (Best Practices)
About these tips
These tips are not all applicable to every project.
They are based on my experience with projects with small teams from 3 to 20 people.
There’s is a price for structure, re-usability, clarity, and so on — team size and project size determine whether that price should be paid.
Many tips are a matter of taste (there may be rivalling but equally good techniques for any tip listed here).
Some tips may fly in the face of conventional Unity development. For instance, using prefabs for specialisation instead of instances is very non-Unity-like, and the price is quite high (many times more prefabs than without it). Yet I have seen these tips pay off, even if they seem crazy.
