I'm looking for an algorithm solving a problem with detecting collisions between non-aligned objects in 2d (e.g. rectangles), as below:

How do I go about it? All of the articles I found online handle axis-aligned objects, which is not what I need. As for know, I handled only collisions between circles by measuring distance between their centers, but this case is way more difficult.

Just rotated rectangles or also less convenient shapes? – harold Sep 17 '17 at 19:58

You can rotate both rectangles simultaneously sothat one of them become axis aligned, and the problem becomes much easier. – Yves Daoust Sep 17 '17 at 21:12
or just test the circumference lines for intersection ... – Spektre Sep 18 '17 at 06:31
