Too Many Coroutines: A Queue Solution

Tags: , , ,

Unity’s coroutine support is great. So great that it’s easy to go overboard and end up with too many of them. That could be for any number of reasons. Perhaps the coroutines are using too much memory or have too many files open at once. In any case, you’ll need to find a way to limit how many are running at a single time. Today’s article introduces a solution to the problem that queues coroutines so you never have too many running. Read on to learn about the solution and for the class that implements it.

Working Around Iterator Function Limitations

Tags: , , , ,

As you use iterator functions (and yield) more and more, you’ll start to run into some limitations in the C# language. For instance, you can’t yield inside a try block that has a catch block. And the foreach loop doesn’t provide a very good way to catch exceptions when looping over an iterator function, either. Today’s article goes into detail to find solutions to these issues and make iterator functions usable in even the trickiest scenarios!

From AS3 to C#, Part 17: Conditionals, Exceptions, and Iterators

Tags: , , , , , , , , ,

Continuing the series on C# syntax, today we’ll look at the differences an AS3 programmer can expect to encounter when using conditionals (if/else, switch/case/break/goto) and exceptions (try/catch/finally/throw). We’ll also look at iterators, an all-new category for AS3 programmers that empowers us to both iterate however we want and to write coroutines, a kind of lightweight pseudo-thread.
