Usage FlamePluginComponent
A simple usage example:
import 'package:composition_rendering/scene.dart'; import 'package:flame/flame.dart'; import 'package:flame/game.dart'; import 'package:flame_composition_rendering/flame_plugin.dart'; import 'package:flutter/widgets.dart'; void main() { WidgetsFlutterBinding.ensureInitialized(); runApp( GameWidget( game: ExampleLauncher(), ), ); } class ExampleLauncher extends BaseGame { final FlamePluginComponent plugin = FlamePluginComponent(); ExampleLauncher() { plugin.scene = GameScene(); } @override Future<void> onLoad() async { await Flame.images.loadAll([ 'bg.jpg', ]); await add(plugin); } } class GameScene extends Scene { @override void init() { // your play scene } }
Usage SpriteBatchComponent
Alternative SpriteBatch for Flame. Rendering three sprites in one call Canvas.drawRawAtlas
import 'package:flame/components.dart'; import 'package:flame/flame.dart'; import 'package:flame/game.dart'; import 'package:flame_composition_rendering/flame_composition_rendering.dart'; import 'package:flutter/material.dart'; void main() { WidgetsFlutterBinding.ensureInitialized(); Flame.device.fullScreen(); Flame.device.setLandscape(); runApp( GameWidget( game: ExampleLauncher(), ), ); } class ExampleLauncher extends BaseGame { @override Future<void> onLoad() async { await Flame.images.loadAll(['crab.png']); await add(SpriteBatchComponent()); } @override Color backgroundColor() => const Color(0xFFFFFFFF); } class SpriteBatchComponent extends FlameBatchComponent { late final image; late final sprite; @override Future<void>? onLoad() { image = Flame.images.fromCache('crab.png'); sprite = Sprite(image); } @override void beginBatch() { drawSprite(sprite, x: 100, y: 200); drawSprite(sprite, x: 200, y: 200); drawSprite(sprite, x: 300, y: 200); drawSpriteFromComponents(sprite, x: 400, y: 100, rotation: 0.4, scale: 0.6); } }
