Exploring Kotlin Lists
This blog post accompanies a video from our YouTube series which you can find on our Kotlin YouTube channel, or watch here directly!
Today, we’re talking all about lists! Lists are the most popular collection type in Kotlin for a good reason, and we’ll find out why together.
Lists
What’s a list?
If you’ve written Kotlin code before, you’ve definitely seen a list – they’re collections of ordered elements, where each element is accessible via an index. As such, they’re one of the basic building blocks for a lot of Kotlin code.

Today, we are learning about advanced functions that we can use to work with and manipulate all kinds of Kotlin collections!
Checking predicates: any, none and all
Let’s warm up by having a look at a selection of functions that allow us to check conditions for our collection elements.
How I built an "Asteroids" game using Compose for Desktop (Part 1/2)
A while ago, I tweeted about a small game I had created on top of Compose for Desktop: A small clone of the classic arcade game Asteroids, in which you control a space ship with your mouse, and navigate the vastness of space, avoiding and breaking asteroids in the process.
Today, it’s time to take a look under the hood and understand how I built a basic version of this game, and how Compose for Desktop helped me achieve it in just one evening!
Tips & tricks for building a game using Compose for Desktop (Part 2/2)
In the first part of my blog post series about building a small clone of the classic arcade game Asteroids on top of Compose for Desktop, we saw how to implement the main game loop, as well as manage state and draw basic shapes. In this post, we will explore some more details of the game implementation. This includes:
- Rendering details – making sure game objects don’t escape our play area, and using a device-independent coordinate system for rendering
- Geometry and linear algebra – the secret sauce that makes the space ships fly
- Frame-independent movement – so that our game works consistently.
Let’s learn about these topics!

Kotlin Collections! You’ve heard of them, you’ve used them – so it makes sense to learn even more about them! Kotlin’s standard library provides awesome tools to manage groups of items, and we’re going to take a closer look!
