当然有，我也没用screne2d.

Of course there is, I also never use screne2d.

  if(Gdx.input.isTouched())
{
  Vector3 tmp=new Vector3(Gdx.input.getX(),Gdx.input.getY();
  camera.unproject(tmp);
  Rectangle textureBounds=new Rectangle(textureX,textureY,textureWidth,textureHeight);
  // texture x is the x position of the texture
  // texture y is the y position of the texture
  // texturewidth is the width of the texture (you can get it with texture.getWidth() or textureRegion.getRegionWidth() if you have a texture region
   // textureheight is the height of the texture (you can get it with texture.getHeight() or textureRegion.getRegionhHeight() if you have a texture region
  if(textureBounds.contains(tmp.x,tmp.y))
     {
     // you are touching your texture
     }
}
