FPSAnimator

License API Android Weekly Android Arsenal

A simple but powerful Tween / SpriteSheet / ParabolicMotion / animation library for Android TextureView and SurfaceView.

Features

  • The controls Fps possible to animation.
  • Possible for animation of Tween and SpriteSheet and ParabolicMotion in one of TextureView.
  • Possible to animate with low load on the terminal.
  • 28 types of Easing

Basic Usage

Gradle

    dependencies {
        // jCenter
        compile 'com.daasuu:FPSAnimator:0.2.3.2'
    }

Include the FPSTextureView widget in your layout. Set FPS by attribute. Default FPS is 30.
If you use SurfaceView , use FPSSurfaceVIew.

    <com.daasuu.library.FPSTextureView
        android:id="@+id/animation_texture_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:FPSAnimator_fps="24"
        />

In your onCreate method (or onCreateView for a fragment), bind the widget.

    private FPSTextureView mFPSTextureView;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_easing_sample);
        mFPSTextureView = (FPSTextureView) findViewById(R.id.animation_texture_view);
    }

Create an instance of the DisplayObject, please add it to the FPSTextureView.

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    
    DisplayObject bitmapDisplay = new DisplayObject();
    bitmapDisplay
            .with(new BitmapDrawer(bitmap))
            .tween()
            .toX(1600, windowWidth - bitmap.getWidth(), Ease.BACK_IN_OUT)
            .waitTime(1000)
            .alpha(1000, 0f)
            .alpha(1000, 1f)
            .end();
            
    mFPSTextureView
                .addChild(bitmapDisplay)
                .tickStart();

The example above will create a new tween instance that:

  • tweens the target to an x value of rightSide over 1600ms
  • waits 1000 ms
  • tweens the target's alpha from 1 to 0 over 1s
  • tweens the target's alpha from 0 to 1 over 1s

Example

This is the implementation of the sample application.

SpriteSheet

    
    SpriteSheetDrawer spriteSheetDrawer = new SpriteSheetDrawer(
        spriteBitmapB, 
        frameWidth, 
        frameHeight, 
        frameNum)
        .spriteLoop(true);
    
    DisplayObject displayObject = new DisplayObject();
    displayObject
            .with(spriteSheetDrawer)
            .tween()
            .tweenLoop(true)
            .transform(-frameWidth, windowHeight / 2)
            .toX(3000, windowWidth)
            .end();

    mFPSTextureView
                .addChild(displayObject);

SpriteSheet wiki

TweenText

    Paint paint = new Paint();
    paint.setColor(ContextCompat.getColor(this, R.color.colorAccent));
    paint.setTextSize(Util.convertDpToPixel(16, this));

    String tweenTxt = "TweenText";
    float textWidth = paint.measureText(tweenTxt);
    
    TextDrawer textDrawer = new TextDrawer(tweenTxt, paint)
            .rotateRegistration(textWidth / 2, textWidth / 2);

    DisplayObject textDisplay = new DisplayObject();
    textDisplay.with(textDrawer)
            .tween()
            .tweenLoop(true)
            .transform(0, 800)
            .waitTime(300)
            .to(1000, windowWidth - textWidth, 800, 720f, Ease.SINE_OUT)
            .waitTime(300)
            .to(1000, 0, 800, 0f, Ease.SINE_IN)
            .end();

TweenBitmap

```JAVA BitmapDrawer bitmapDrawer = new BitmapDrawer(bitmap) .dpSize(this) .scaleRegistration(bitmap.getWidth() / 2, bitmap.getHeight() / 2);
    DisplayObject bitmapDisplay = new DisplayObject();
    bitmapDisplay.with(bitmapDrawer)
            .tween()
            .tweenLoop(true)
            .transform(300, 400)
            .to(500, 300, 400, 0, 6f, 6f, 0, Ease.SINE_IN_OUT)
            .waitTime(300)
            .transform(300, 400, Util.convertAlphaFloatToInt(1f), 1f, 1f, 0)
            .waitTime(300)
            .end();

```JAVA
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        Paint paint = new Paint();
        paint.setColor(ContextCompat.getColor(context, R.color.colorPrimary));
        paint.setTextSize(Util.convertDpToPixel(20, context));

        textDisplay.with(textDrawer)
                .parabolic()

                .end();

        mFPSTextureView.addChild(textDisplay);
    }

    private void createParabolicMotionBitmap() {
        final DisplayObject bitmapDisplay = new DisplayObject();

        bitmapDisplay.with(new BitmapDrawer(mBitmap).dpSize(context))
                .parabolic()
                .transform(0, mFPSTextureView.getHeight())
                .reboundBottom(false)
                .accelerationX((float) (15 + Math.random() * 7))
                .initialVelocityY((float) (-65 + Math.random() * 15))
                .bottomHitCallback(new AnimCallBack() {
                    @Override
                    public void call() {
                        mFPSTextureView.removeChild(bitmapDisplay);
                    }
                })
                .end();

        mFPSTextureView.addChild(bitmapDisplay);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mFPSTextureView.tickStart();

        mTimer = new Timer();
        mTimer.schedule(new TimerTask() {
            @Override
            public void run() {
                for (int i = 0; i < 5; i++) {
                    createParabolicMotionBitmap();
                }
            }
        }, 0, 100);
    }

Container

A Container is a nestable display list that allows you to work with compound display elements.
For example you could group arm, leg, torso and head Bitmap instances together into a Person Container, and transform them as a group, while still being able to move the individual parts relative to each other. Children of containers have their transform and alpha properties concatenated with their parent Container.
Containers have some overhead, so you generally shouldn't create a Container to hold a single child.
