Can static classes help with performance?

Oh no i’m not having performance issues atm,

DO NOT OPTIMIZE CODE JUST BECAUSE… If you don’t have a problem, DO NOT OPTIMIZE!

If you DO have a problem, always start by using the profiler:

Window → Analysis → Profiler

Failure to use the profiler means you’re just guessing, making a mess of your code for no good reason.

Is it still worth optimizing square roots in 2021+?

It depends on the target architecture and runtime library of course, as all computer code runs on the actual CPU where your game is running, not some “theoretical magical global CPU of today” construct. But in 2021 a floating point unit (FPU) is pretty standard on most targets. All that said, don’t do needless work, especially on mobile, as that just burns down battery life. If you suspect you have a performance bottleneck, DO NOT START MAKING OPTIMIZATION CHANGES!! Instead, start with the …

How to efficiently copy transform data into an array

Just so you know, the entire UnityEngine.UI system is available in source control from the package manager (and from github) and you can look at it and probably see there isn’t going to be a lot of fat. If there are some particular specific widgets you use in there that are too slow because of the use-generalization assumptions made, you might be able to get some benefit by tweaking them, but since so much of mobile performance bumps against pixel fill bounds, it’s unlikely to get you much ben…

Just because i “reduce the total ammount of lines”.

Lines mean nothing. CPU instructions also mean nothing.
