Why do Physics2D NonAlloc functions get deprecated?

Questions & Answers

Hello Community,

at the moment, I am refactoring a 2D project. When I wanted to change the function Physics2D.OverlapCircleAll to Physics2D.OverlapCircleAllNonAlloc I noticed, that all static 2D NonAlloc functions are marked as deprecated in the documentation, and it is recommanded, to use the
“standard” methode instead:

I researched why this will happen, and also tested, if the Non-NonAlloc functions maybe got an upgrade, but they are still producing garbage. Do you have an idea, what could the plan of removing this handy functions be?

From what I see in the documentation, the regular OverlapCircle method has an overload that takes an array where the results will be placed. So my guess is that they want to remove OverlapCircleAll and OverlapCircleAllNonAlloc and use a single method with overloads instead.

But also from my experience, Unity rarely if ever actually removes obsolete methods. There are methods and properties that are marked as obsolete since Unity 5, that are still in 2021 versions…
