颤动火焰精灵复制品在Android上，而不是Iphone上？
颤动火焰精灵复制品在Android上，而不是Iphone上？
提问于 2020-04-06 05:54:21
使用Flutter Flame engine和AndroidStudio开发一个游戏。render函数使用canvas.save()和canvas.render()函数来确保帧之间的屏幕清晰(以防止重复的精灵绘制)。在IPhone模拟器上，应用程序按预期运行，但是在多个安卓模拟器上，会渲染重复的精灵。不知道为什么会这样。感谢任何人的帮助！

你不必自己处理渲染方法，只需将你的SpriteComponent添加到游戏中，它就会为你处理渲染。
class ThisGame extends Game {
final SharedPreferences storage;
Size screenSize;
double tileSize;
Player player;
double spriteSize = 128;
double timeElapsed = 0;
ThisGame(this.storage) {
initialize();
}
initialize() async {
resize(await Flame.util.initialDimensions());
player = Player();
player.x = 0;
player.y = 0;
add(player); // <-- Like this
}
@override
void update(double t) {
super.update(t) // Also don't forget to call super
timeElapsed += t;
if (timeElapsed > 1) {
timeElapsed = 0;
player.y += t * 300;
player.x += t * 300;
}
}
@override
void resize(Size size) {
screenSize = size;
tileSize = screenSize.width / 9;
}
}
class Player extends SpriteComponent {
Player() : super.square(128.0, 'player.png') {
this.angle = 0.0;
}
}此外，不要忘记在更新覆盖中调用super.update(t)。
