C# Invoke in Unity! - Beginner Scripting Tutorial

Watch this video in context on Unity Learn:

The Invoke functions allow you to schedule method calls to occur at a later time. In this video you will learn how to use the Invoke, InvokeRepeating, and CancelInvoke functions in your Unity scripts.

Finally finally i was looking this for so LONG

[siddheshwarmahant]

I have que that what should I use Invoke or Instantiate for creating a shoot bullet in loop???

[stashorodnyansky]

I wish there were no Invokes at all. In most cases Invoke used in game is a result of poor design and it only makes the code more difficult to debug. I prefer using coroutines - more flexibility and control. And they are also not always the best solution.

Why did you even get Dislikes?
Literally other YouTubers stretch their videos just to get more watch time.
Thank you Unity ❤

if start method is only called once, why is invokerepeating called again and again? please explain
Thanks in advance.

Heyyy!
I wrote this

void Start()
{
InvokeRepeating("rainBalls", 2, 1);
}
it rains targets as you have demonstrated.

But when I wrote this:

void Start()
{
InvokeRepeating("rainBalls", 2, 1);
CancelInvoke("rainBalls");
}

it does not rain immediately. I understand what happened. But what I'm looking for is what function such that the Invoke will stop after a certain time. Can you help me?

[brownshawarmaofficial]

what if you want to CancelInvoke at a certain time?

[welltypedwitch]

why doesn't Invoke just accept an Action (or any delegate really)? Then you wouldn't need to rely on reflections.

[kattenelvis]

Is there a way to pass in parameters with Invoke?

[bhavyakukkar]

is there a similar function which calls a method continuously for a given time despite calling the "invoking" method just once?

[rsquad]

public static Object Instantiate(Object original, Vector3 position, Quaternion rotation);

[nixoletas]

How do i use Invoke for less than a second?

[quasar]

What if you have invoked multiple methods with the same name, and you want to cancel only a single one of them ? Does CancelInvoke() stop al methods with the same name, or the first one the software kept in memory ?

[rituvats]

Sir my invoke doesn't call method

[christobanistan]

Can you guys PLEAse please please use VS dark theme? It's so freaking painful/ hard to read on a white background!

[christobanistan]

Using UniRx is a far better way of doing something like this. IT gives vastly better control with Observables.

[TheCharoplet]

This method is bad and should be removed from Unity

Please don’t teach beginners to use Invoke or InvokeRepeating, it’s very bad practice and far less efficient that using coroutines to repeat a function call or a delegate to call a variable function.
