我已经显示的图像在与libgdx屏幕的中央。如果我刷卡左图像应的向左移动的，如果我向右滑动图像应的向右移动的。

随后刷卡向左应该向左移动图像。同样应该发生的权利。我用 GestureListener 。

它可以在一定程度上在这个意义上，如果我刷卡左留下第一张图像移动。但在那之后，如果我尝试刷右侧的图像还是向左移动。

让我怎么克服这libgdx ??

 类MyGestureListener实现GestureListener {

        @覆盖
        公共布尔一扔（浮点为arg0，浮动ARG1，ARG2 INT）{
            // TODO自动生成方法存根


              如果（arg0都大于0）
               IX + = 20;
              其他
             //否则，如果（为arg0 * 100＆GT;九）
                  IX-= 20;
               的System.out.println（你好...............+九）;
            返回true;
        }

   Gdx.input.setInputProcessor（新GestureDetector（0.0，0.0，0.0，5F，新MyGestureListener（）））;

   batch.draw（splashTexture，IX，IY）;
 

解决方案

我曾经在这个环节的例子。 https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/GestureDetectorTest.java.

  @覆盖
   公共布尔一扔（浮点velocityX，浮velocityY，INT按钮）{
       如果（Math.abs（velocityX）＆GT; Math.abs（velocityY））{
               如果（velocityX大于0）{
                       IX + = 20; // x cordinate
               }否则如果（velocityX℃，）{
                      IX-= 20;
               } 其他 {
                 // 没做什么。
               }
       }其他{

          //忽略的输入，因为我们不关心向上/向下刷卡。
       }
 返回true;
}
 

I have displayed a image at the center of the screen with libgdx. If i swipe left the image should move left and if i swipe right image should move right.

Subsequent swipes to the left should move the image left. The same should happen for right. I used GestureListener.

It works to some extent in the sense if i swipe left first image moves left. But after that if i try to swipe right the image still moves left.

So how do i overcome this in libgdx??

    class MyGestureListener implements GestureListener {

        @Override
        public boolean fling(float arg0, float arg1, int arg2) {
            // TODO Auto-generated method stub


              if(arg0>0)
               iX += 20;
              else
             // else if(arg0*100>iX)
                  iX-=20;
               System.out.println("Hello..............."+iX);
            return true;
        }

   Gdx.input.setInputProcessor(new GestureDetector(0.0f, 0.0f,0.0f, 5f,new MyGestureListener()));

   batch.draw(splashTexture, iX, iY);

I used the example in this link. https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/GestureDetectorTest.java.

   @Override
   public boolean fling(float velocityX, float velocityY, int button) {
       if(Math.abs(velocityX)>Math.abs(velocityY)){
               if(velocityX>0){
                       iX+=20;//x cordinate
               }else if (velocityX<0){
                      iX-=20;
               } else {
                 // Do nothing.
               }
       }else{

          // Ignore the input, because we don't care about up/down swipes.
       }
 return true; 
}
