Trajectory prediction in Unity

Predict trajectory with Physics.Simulate. Not sure about performance if there is a lot of stuff going on, but should be absolutely fine for small simulations. Anyway in case you use Physics.Simulate a lot dont forget to always profile before optimizing. Or if you are still in a preproduction phase, make a small proof of concept with expected amount (and more for greater confidence) of operations to simulate, so you can be sure that this approach is suitable for your case.

Talking to your unmanaged code efficiently from Unity using P/Invoke

How to use P/Invoke with blittable types. A type is blittable if it has the same memory representation in C# as in the target language.

Polygon Clipping (Part 1 & 2)

Polygon clipping is an interesting problem: how do you intersect, union, or diff two polygons?
The Greiner-Hormann clipping algorithm is quite beautiful and intuitive. However the Greiner-Hormann clipping algorithm cannot deal with coincident lines. This turns out to be a huge pain – so there is part 2 that works for all polygons.

Improve C# code performance with Span<T>

Obviously fast Span<T> is not available in Unity yet, but the post has an interesting point about how applying domain knowledge could result in better performance than just using new fancy stuff

Immediate Window – Interact with your Code while Debugging in Rider

In case you missed this feature like I did: the Immediate Window in Rider debugger. A valuable part of the debugging experience is experimentation, modifying variables and determining whether the outcomes were what we expected. The post has a simple example, would be glad to hear your ideas how it could be helpful in the comments.

Ruben Gonzalez | Dependency Injection on Unity

Make sure to read the second part. Far from ideal DI implementation, but worth to read if you'd like to understand how DI containers might work under the hood.
