To confirm that it’s gone, check out the IL now: The first goal is accomplished: passing instance methods no longer creates garbage. You can see that the garbage is created when setting up the cached Action fields but never when actually using them later. TestAnonymousMethod ( ) } void TestSecond ( ) If (Vector3.Distance(transform.position, System using UnityEngine public class TestScript : MonoBehaviour Unity calls the Update method several times per second, so if you don’t need a task to be repeated quite so often, you can put it in a coroutine to get a regular update but not every single frame.įor example, you can might have an alarm in your application that warns the player if an enemy is nearby with the following code: bool Proximit圜heck() You can use WaitForSeconds to spread an effect over a period of time, and you can use it as an alternative to including the tasks in the Update method. If you want to introduce a time delay, use WaitForSeconds: IEnumerator Fade() Coroutine time delayīy default, Unity resumes a coroutine on the frame after a yield statement. ![]() This will wait 10 secs between 'doing something', not 'execute every 10 secs'. If there is no GUI, it will run on a thread pool thread. The loop counter in the Fade function maintains its correct value over the lifetime of the coroutine, and any variable or parameter is preserved between yield statements. In an application with a GUI, this will execute DoSomething on the UI thread via the message loop, like any other event (like a button click handler). To set a coroutine running, you need to use the StartCoroutine function: void Update() The yield return nullline is the point where execution pauses and resumes in the following frame. In C#, you declare a coroutine like this: IEnumerator Fade()Ī coroutine is a method that you declare with an IEnumerator return type and with a yield return statement included somewhere in the body. However, it can be more convenient to use a coroutine for this kind of task. To work around this situation, you could add code to the Update function that executes the fade on a frame-by-frame basis. The intermediate values are never displayed, and the object disappears instantly. However, this example method executes in its entirety within a single frame update. To make the fading visible, you must reduce the alpha of the fade over a sequence of frames to display the intermediate values that Unity renders. In this example, the Fade method doesn’t have the effect you might expect. Damage per second: 120 while firing (85.71 overall w/recharge - 80 w/reload). ![]() Coroutine exampleĪs an example, consider the task of gradually reducing an object’s alpha (opacity) value until it becomes invisible: void Fade()įor (float alpha = 1f alpha >= 0 alpha -= 0.1f) It’s best to use coroutines if you need to deal with long asynchronous operations, such as waiting for HTTP transfers, asset loads, or file I/O to complete. If you want to use multi-threaded code within Unity, consider the C# Job System. ![]() If you want to reduce the amount of CPU time spent on the main thread, it’s just as important to avoid blocking operations in coroutines as in any other script code. Synchronous operations that run within a coroutine still execute on the main thread. However, it’s important to remember that coroutines aren’t threads. In situations where you would like to use a method call to contain a procedural animation or a sequence of events over time, you can use a coroutine. This means that any action that takes place within a method must happen within a single frame update. In most situations, when you call a method, it runs to completion and then returns control to the calling method, plus any optional return values. In Unity, a coroutine is a method that can pause execution and return control to Unity but then continue where it left off on the following frame. A coroutine allows you to spread tasks across several frames.
