Clock, a Unity C# Tutorial. In this tutorial we'll write a small C# script to animate the arms of a very simple clock.
You'll learn to create an object hierarchy;create a script and attach it to an object;access namespaces;use the Update method;rotate stuff based on time. You're assumed to already have a basic understanding of Unity's editor. If you've played with it for a few minutes you're good to go. Creating the clock We start by creating a new Unity project without any packages. We need an object structure to represent the clock. We'll use simple boxes to visualize the arms of the clock. Android Help - How to suspend the game during a phone call. Coroutines with IEnumerable and yield return. There was a brief flurry of excitement about the fancy yield return syntax when the C# 2.0 specification was first published some years ago, and the idea of it being used for creating coroutines.
This quickly died down, as far as I can see anyway. Either people forgot the idea, or it became such boringly standard practice that no one ever thinks to discuss it anymore. How to restart coroutine on event. Okay, I got this working now with a mixture of the two: a coroutine carrying a timestamp of its own invocation and the parent class carrying a timestamp of the last invocation of its coroutine.
When the function gets invoked, it will set both the class timestamp and its own timestamp to be the same. Before each action, it will check whether the two are identical, i.e. if in the meantime another one was invoked. For robustness, the timestamp doesn't store the actual time but the order of invocation.The stamp is big enough for 1000 invocations every second for about 1.5 months... Note that this specific example is bound to a parent class. Stop Current Coroutine, Then Restart It. Trying to trigger a coroutine loop at random intervals, but before it starts, it needs to interrupt and exit the previous instance of it, so only one instance of the loop is running at a time: while (x == true){ Do_Action_Over_A_Number_Of_Frames(); yield;} Tried a bunch of different methods with no luck.
Can't use StopCoroutine() since I have multiple instances of it running on other game objects. I can turn off the previous loop by making x=false but then the new loop won't start. I could have x=false followed by x=true but then the first loop will never exit and the second loop will stack. I could disable and enable the script that contains the above coroutine but that seems like overkill. I feel like I'm missing something really simple but scoured the Forums and Answers with no luck. Advanced Coroutines (inner workings) Motivation You should read this article if you really want to know what is going on behind the scenes in coroutines.
It will be very useful if you are following the FSM tutorial and you want to get the grimy details on how we can create interruptable coroutines that can be later resumed. This is an advanced subject and you don't really need to know this if you just want to use coroutines. If you are building systems and frameworks, or you are just curious then read on!

In 1980 (you do the math) Matt started computer programming (on a ZX80) and has been programming ever since. In 1985, Matt wrote the lyrics, and was a member of the band that played (and sang, sorry about that by the way) the music on the B-side of the audio cassette carrying the computer game Confuzion (wikipedia.org/wiki/Confuzion). Matt holds a bachelor's degree in Business Computing (Huddersfield University, UK), and as that was a bit boring, he went on to get a masters in Artificial Intelligence (Aberdeen University, Scotland), and a PhD in Computational Musicology (Open University, UK). Having run out of money after 10 years as a full-time student, he began his career as a lecturer and academic. Chico Queiroz Chico Queiroz is a multimedia designer from Rio de Janeiro, Brazil.
