我正在尝试更改Libgdx屏幕之间的动画。我想写自定义动画(淡入淡出,淡出等)。有人能给我一个线索吗? 我似乎无法在Libgdx代码中找到转换的实现。

这就是我的所作所为:
FadeIn非常简单,只需将其添加到你的fadein Screens show():
stage.getRoot().getColor().a = 0;
stage.getRoot().addAction(fadeIn(0.5f));
FadeOut有点棘手。您不想立即切换屏幕,因此不要调用game.setScreen(newScreen)在您的淡出屏幕中创建一个方法,如下所示:
public void switchScreen(final Game game, final Screen newScreen){
stage.getRoot().getColor().a = 1;
SequenceAction sequenceAction = new SequenceAction();
sequenceAction.addAction(fadeOut(0.5f));
sequenceAction.addAction(run(new Runnable() {
@Override
public void run() {
game.setScreen(newScreen);
}
}));
stage.getRoot().addAction(sequenceAction);
}
像这样,你会在淡出过程中延迟屏幕切换。

我使用Scene2D和通用补间引擎实现了一些滑动过渡。你可以在这里找到示例代码。

更新:本文说明了我实现滑动过渡的方法。底部有一个链接,可以带您到这里进行一组演示https://github.com/alistairrutherford/libgdx-demos
有关如何构建演示的明确说明,但您至少需要掌握maven以及如何设置它。

我实施了类似的方法。感谢Gustavo Steigert,我从他的博客中学到了很多东西 在这里你可以找到他的fadeIn和fadeOut序列的例子。

你可以完整地浏览他的博客,以更好地了解事物的流程,并在帖子的源代码中找到每个帖子的标签。

这是我的游戏在屏幕之间的过渡动画中的示例代码:

课程中:
MainGame
我的所有屏幕都延伸为@Override public void setScreen(final Screen screen) {
if (getScreen() == null)
{
createScreenInAction(screen);
return;
}
createScreenOutAction(getScreen(), new Runnable() {
@Override public void run() {
createScreenInAction(screen);
}
});
}
private void createScreenOutAction(final Screen screen , Runnable runnable) {
Actor actor = ((BaseScreenAdapter) screen).getStage().getRoot();
actor.setOrigin(WIDTH_HALF,HEIGHT_HALF);
actor.getColor().a = 1;
SequenceAction sequenceAction = new SequenceAction();
sequenceAction.addAction(Actions.parallel(Actions.alpha(0,SCREEN_SWITCH_DURATION) , Actions.scaleTo(1.5f,1.5f , SCREEN_SWITCH_DURATION, Interpolation.exp5)));
sequenceAction.addAction(Actions.run(runnable));
actor.addAction(sequenceAction);
}
private void createScreenInAction(final Screen screen) {
StarsGame.super.setScreen(screen);
Actor actor = ((BaseScreenAdapter) screen).getStage().getRoot();
actor.setOrigin(WIDTH_HALF,HEIGHT_HALF);
actor.getColor().a = 0;
SequenceAction sequenceAction = new SequenceAction();
sequenceAction.addAction(Actions.scaleTo(1.5f,1.5f , 0));
sequenceAction.addAction(Actions.parallel(Actions.alpha(1,SCREEN_SWITCH_DURATION) , Actions.scaleTo(1.0f,1.0f , SCREEN_SWITCH_DURATION , Interpolation.exp5)));
actor.addAction(sequenceAction);
}
