Hello everyone. Today I have prepared a guide about Flame for you. Developers who are bored of constantly developing mobile applications, who want to try something different, who have an idea and want to realize it from a familiar place, this place is for you! Let’s start by getting to know Flame first.
What is Flutter Flame?
Flutter Flame is an open source game engine for developing Flutter-based 2D games. It allows you to create games for mobile, web and desktop platforms using the Dart language. You can bring the power and flexibility of Flutter to the game world and experience a fast and easy game development experience.
Why Preferable?
First of all, as with Flutter in general, you can create games for Android, iOS and web with a single code base.
Assuming you already have Flutter knowledge, you won’t be overwhelmed by the details of a new technology for your simple game, and you will quickly grasp Flame.
It’s open source, so you can easily get support from the developer community.
Let’s look at the main features of Flame.
Game Loop
Flame allows games to run in a continuous loop. Thanks to this loop, all objects on the game screen are updated and drawn. This loop is based on two main functions:
update(dt): Updates of game objects such as position, state, etc. are done here.
render(canvas): The graphics to be drawn on the screen are defined here.
Component System
Flame offers a component-based approach to creating game objects. You can define and manage objects such as players, enemies, obstacles, etc. as components.
class Player extends PositionComponent {
@override
void render(Canvas canvas) {
// You can write the player drawing codes here
}
@override
void update(double dt) {
// You can write the player update codes here
}
}
Sprite ve Animasyon Desteği
Sprites are graphical elements within the game. Flame allows you to easily manage sprite-based animations.
final sprite = await Sprite.load('player.png');
Çarpışma Tespiti (Collision Detection)
In games, it is important to detect the collision of objects. Flame has a collision detection system that facilitates this process.
bool collision = player.toRect().overlaps(enemy.toRect());
Flame ile Yapılabilecek Basit Bir Oyun Taslağı
In this section, I have prepared an outline that you can use as a guide when you start developing a game.
First, after creating the project, we install the flame package.
flutter pub add flame
Then we can create our Main Game class.
import 'package:flame/game.dart';
class MyGame extends FlameGame {
@override
void render(Canvas canvas) {
// Draw game objects here
}
@override
void update(double dt) {
// Make game updates here
}
}
And finally we start the game.
void main() {
runApp(GameWidget(game: MyGame()));
}
This is of course a very simple and general outline. There are a lot of things to change and improve regarding the game’s features and genre. At this point, there is a repo you can review. It has a lot of resources and examples. After my outline, you can make use of this repo to move forward. And of course you should also read the official documentation. The link to both is below.
As a result, Flutter Flame allows you not only to develop games, but also to make creative projects with your Flutter knowledge. It’s a great opportunity to try yourself in the game world! I hope this was useful.
Thank you.
Selin.
