ZeroGravityAnimation

Make random object fly on your screen.

The repo helps in easier development of flying random objects on random directions (or on specific directions) to give a goodUI experience for the user. Specifically made for gaming purpose, the repo will be highly useful for apps that deals with space related animations, thus named as ZeroGravityAnimation. The animation works with a class called OverTheTopLayer, that makes the object to fly on the top of the screen. A ViewGroup layout can be passed optionally that acts as a container for the animating objects.

####Sample:

The image illustrates the stars flying beneath the earth with the help of container layout while a meteor and a satellite flying on the top of screen through OverTheTopLayer.

####Usage:

int imgResource = R.drawable.star; // your animating object here
int count = 1;  // # of objects to fly
float scale = 0.2f; // scaling factor for the animating objects - value ranges from 0.0 to 1.0

// directions are optional and by default RANDOM will be picked
Direction origin = Direction.LEFT; // animation origin direction - can also use Direction.TOP, Direction.BOTTOM, Direction.LEFT or Direction.RANDOM
Direction destination = Direction.RIGHT; // same case as above for destination


ZeroGravityAnimation animation = new ZeroGravityAnimation();
animation.setCount(count);
animation.setScalingFactor(scale);
animation.setOriginationDirection(origin);
animation.setDestinationDirection(destination);
animation.setImage(resId);
animation.play(this);

#####Animation Listener: Default animation listener can used to collect events of this animation.

animation.setAnimationListener(new Animation.AnimationListener() {
                                           @Override
                                           public void onAnimationStart(Animation animation) {

                                           }

                                           @Override
                                           public void onAnimationEnd(Animation animation) {
                                          
                                           }

                                           @Override
                                           public void onAnimationRepeat(Animation animation) {

                                           }
                                       }
        );
```

#####Animation Object Container Specification:
Wanted you animation to take place beneath certain views - like the stars that fly beneath Earth in the above demo? 
Make sure you design your layouts to have a container layout (FrameLayout) that lies below than the original views and use the following code
    
```java
  
  ViewGroup container = (ViewGroup) findViewById(R.id.animation_container_layout); 
  animation.play(this,container);
```
