What is the Work of Invoke in Game Development? 

As you have just started learning about game development, it is very normal that at first the term ‘invoke’ will sound a bit confusing but once you understand it, you will understand that it is one of the most coolest functions which the professional game developers use to control how things happen inside a game.  

In game development, especially when we are using game engines like Unity, Invoke is a function which allows us to call another function after a certain amount of time. In simple terms we can say that it is like setting a timer. 

For example: 

So basically, Invoke helps in timing events inside the game without you having to keep checking the clock yourself. 

Why is Invoke Important in Game Development? 

Imagine playing a shooting game of your choice where enemies appear randomly. Now, suddenly if all the enemies popped up at once then it will be impossible for you to shoot all of them at once. And it will feel like the game is absolutely messy and unplayable. But with Invoke, the developer can make enemies appear one after another with proper timing, making the game more exciting as well as challenging. 

Here are a few real uses of Invoke:

Spawning Objects 

New obstacles, power-ups, or enemies can be set to appear after a delay. 

Creating Suspense 

In horror games such as Pacify, Kamala etc. there is a use invoke to trigger sudden sounds or jumpscares after a few seconds.  

Smooth Gameplay 

Instead of everything happening instantly, game developers use Invoke to space out events which makes the game more fun to the players.  

Now, you might ask can we write timers manually? 

What is the best way to Invoke the right way? 

To be very honest, the best way to understand invoke is by practicing it in real projects. That’s where a structured game development course will help you out! When you learn Invoke as well as other coding concepts directly from experienced mentors that will be much easier for you to learn it. From the course you will be  learning along with the fundamental concepts how professionals use invoke in actual game projects.  

This way, you are not just learning coding syntax…you will be learning how to think like a developer. And that is what makes a difference.  

To Wrap Up… 

This is one of the most important concepts in game development. And as a beginner you will need to learn it very properly. If you’re serious about becoming a game developer, understanding small functions like Invoke is very important. So, without just choosing random concepts, learn step by step concepts from fundamentals to advanced with the assistance of game development course. All the best!
