Specifically made for 7 | gaming purpose, the repo will be highly useful for apps that deals with space related 8 | animations, thus named as ZeroGravityAnimation. The animation works with a class called 9 | OverTheTopLayer, that makes the object to fly on the top of the screen. A ViewGroup layout 10 | can be passed optionally that acts as a container for the animating objects. 11 | 12 | ####Sample: 13 | 14 | The image illustrates the stars flying beneath the earth with the help of container layout while a meteor and 15 | a satellite flying on the top of screen through OverTheTopLayer. 16 | 17 | ![zero](https://cloud.githubusercontent.com/assets/13122232/9293135/fdfffd2a-443b-11e5-9710-bdf98e610c37.gif) 18 | 19 | ####Usage: 20 | 21 | ```java 22 | 23 | int imgResource = R.drawable.star; // your animating object here 24 | int count = 1; // # of objects to fly 25 | float scale = 0.2f; // scaling factor for the animating objects - value ranges from 0.0 to 1.0 26 | 27 | // directions are optional and by default RANDOM will be picked 28 | Direction origin = Direction.LEFT; // animation origin direction - can also use Direction.TOP, Direction.BOTTOM, Direction.LEFT or Direction.RANDOM 29 | Direction destination = Direction.RIGHT; // same case as above for destination 30 | 31 | 32 | ZeroGravityAnimation animation = new ZeroGravityAnimation(); 33 | animation.setCount(count); 34 | animation.setScalingFactor(scale); 35 | animation.setOriginationDirection(origin); 36 | animation.setDestinationDirection(destination); 37 | animation.setImage(resId); 38 | animation.play(this); 39 | ``` 40 | 41 | 42 | #####Animation Listener: 43 | Default animation listener can used to collect events of this animation. 44 | ````java 45 | animation.setAnimationListener(new Animation.AnimationListener() { 46 | @Override 47 | public void onAnimationStart(Animation animation) { 48 | 49 | } 50 | 51 | @Override 52 | public void onAnimationEnd(Animation animation) { 53 | 54 | } 55 | 56 | @Override 57 | public void onAnimationRepeat(Animation animation) { 58 | 59 | } 60 | } 61 | ); 62 | ``` 63 | 64 | #####Animation Object Container Specification: 65 | Wanted you animation to take place beneath certain views - like the stars that fly beneath Earth in the above demo? 66 | Make sure you design your layouts to have a container layout (FrameLayout) that lies below than the original views and use the following code 67 | 68 | ```java 69 | 70 | ViewGroup container = (ViewGroup) findViewById(R.id.animation_container_layout); 71 | animation.play(this,container); 72 | ``` 73 | 74 | ###Apps using ZeroGravityAnimation: 75 | [Goldhunt Game](https://play.google.com/store/apps/details?id=com.cooltechworks.goldhunt)| 76 | ------------ | 77 | ![goldhuntdemo](https://cloud.githubusercontent.com/assets/13122232/9293580/3521f486-444e-11e5-9de2-3b9cab9a13f6.gif)| 78 | 79 | 80 | 81 | 82 | Developed By 83 | ============ 84 | 85 | * Harish Sridharan - 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | -------------------------------------------------------------------------------- /app/src/main/java/com/cooltechworks/zerogravityanimation/MainActivity.java: -------------------------------------------------------------------------------- 1 | package com.cooltechworks.zerogravityanimation; 2 | 3 | import android.app.Activity; 4 | import android.os.Bundle; 5 | import android.view.ViewGroup; 6 | import android.view.animation.Animation; 7 | 8 | import com.cooltechworks.zerogravityanimation.direction.Direction; 9 | 10 | /** 11 | * Created by Harish Sridharan on July 20 2015. 12 | */ 13 | public class MainActivity extends Activity { 14 | 15 | public void onCreate(Bundle savedState) { 16 | super.onCreate(savedState); 17 | setContentView(R.layout.act_main); 18 | 19 | for(int i=0;i<5;i++) { 20 | // stars will fly behind the earth. 21 | flyStars(R.drawable.starglow); 22 | } 23 | 24 | // meteor will fly over the earth 25 | flyObject(R.drawable.meteor, 20000, Direction.RIGHT, Direction.LEFT, 1f); 26 | // satellite will fly over the earth. 27 | flyObject(R.drawable.satellite, 10000, Direction.LEFT, Direction.RIGHT, .4f); 28 | 29 | 30 | } 31 | 32 | /** 33 | * Animate the bigger objects. 34 | * @param resId image resource id of bigger object. 35 | * @param duration time duration for animation. 36 | * @param from origin direction 37 | * @param to destination direction. 38 | * @param scale scales the flier 39 | */ 40 | public void flyObject(final int resId, final int duration, final Direction from, final Direction to, final float scale) { 41 | 42 | ZeroGravityAnimation animation = new ZeroGravityAnimation(); 43 | animation.setCount(1); 44 | animation.setScalingFactor(scale); 45 | animation.setOriginationDirection(from); 46 | animation.setDestinationDirection(to); 47 | animation.setImage(resId); 48 | animation.setDuration(duration); 49 | animation.setAnimationListener(new Animation.AnimationListener() { 50 | @Override 51 | public void onAnimationStart(Animation animation) { 52 | 53 | } 54 | 55 | @Override 56 | public void onAnimationEnd(Animation animation) { 57 | 58 | flyObject(resId, duration, from, to, scale); 59 | } 60 | 61 | @Override 62 | public void onAnimationRepeat(Animation animation) { 63 | 64 | } 65 | }); 66 | 67 | ViewGroup container = (ViewGroup) findViewById(R.id.animation_bigger_objects_holder); 68 | animation.play(this,container); 69 | 70 | } 71 | 72 | /** 73 | * Animates the flying stars. 74 | * @param resId star image resource id. 75 | */ 76 | public void flyStars(final int resId) { 77 | 78 | ZeroGravityAnimation animation = new ZeroGravityAnimation(); 79 | animation.setCount(1); 80 | animation.setScalingFactor(0.2f); 81 | animation.setOriginationDirection(Direction.RANDOM); 82 | animation.setDestinationDirection(Direction.RANDOM); 83 | animation.setImage(resId); 84 | 85 | animation.setAnimationListener(new Animation.AnimationListener() { 86 | @Override 87 | public void onAnimationStart(Animation animation) { 88 | 89 | } 90 | 91 | @Override 92 | public void onAnimationEnd(Animation animation) { 93 | 94 | flyStars(resId == R.drawable.starglow ?
