Getting the Result of an Iterator

Tags: , , ,

Iterators (functions that yield) are great for representing asynchronous processes such as web calls, updating state over time, and multi-step operations. One unfortunate downside is that it’s tough to return a result from them. Today’s article explores several workarounds to this problem before ultimately arriving at a clean, easy-to-use solution to the problem. Read on to learn how to make iterators more useful!

Unity Coroutine Performance

Tags: , ,

Unity’s coroutine support allows you to easily create pseudo-threads and write synchronous-looking code that doesn’t block the rest of the app. They can be very handy for a variety of tasks. Before using them, we should understand the performance cost. Today’s article takes a look at the cost of starting a coroutine as well as the cost of running it. Just how expensive are they? Read on to find out!
