Introduction to octrees

As an addition to the previous post: some theory about octree and use cases. Octrees are often used in 3D, so if you need it in 2D, then use quadtree which is basically the two-dimensional analogue of octree.

Clean Design Documentation Principles

A good set of principles to work with design docs. A good design phase saves a lot of time, as it makes you evaluate the requirements and think about corner cases way before it is engraved in stone (implemented in code).

RecordPhysicsAsAnimations: A Unity tool that lets you bake physics movements of an object and its children into animation and possibly let you save fps.

That's how destruction is made in The Ascent for example.

Problem-Solving Techniques: The Sniper vs the General

I don't really agree with the metaphor, but the main point is valid: the probability of a successful guess drops with each attempt, so try to use both techniques when solving an issue.

Performance traps of ref locals and ref returns in C#

Be cautious with ref returns because they can break encapsulation.
Be cautious with readonly ref returns because they’re more performant only for readonly structs and could cause performance issues for regular structs.
Be cautious with readonly ref locals because they also could cause performance issues for non-readonly structs causing defensive copy each time the variable is used.
