I am working on a simple game using Flame and Flutter. I am following this tutorial: Create a Mobile Game with Flutter and Flame – Beginner Tutorial
But after I added some code following tutorial line:
flameUtil.addGestureRecognizer(tapper);
appears underlined and onTap function is not working.
API of flutter-flame library is constantly evolving and the solution from tutorial above might not work anymore.
I had some hard times to re-implement example from this presentation: https://www.youtube.com/watch?v=sFpjEH-ok2s, so you're not alone :-)
Newer versions of flutter-flame like 0.23.0, requires to make it work to add TapDetector mixin to your BaseGame class like below:
class MyBaseGame extends BaseGame with TapDetector, DoubleTapDetector {
@override
void onTapDown(_) {
add(RenderedTimeComponent(Timer(1)..start()));
}
@override
void onDoubleTap() {
add(RenderedTimeComponent(Timer(5)..start()));
}
}
Thanks to this your code of BoxGame initialization is just:
BoxGame game = BoxGame();
runApp(game.widget);
without declarations of Util and TapGestureRecognizer.
You can use TapDetector mixin:
class WarriorGirlGame extends FlameGame with TapDetector { @override void onTapDown(TapDownInfo info) { ... } }
