# About

Wein2DAndroid is a library for handling graphics, input and sound for Android apps in Java with very similar method names and structure to Wein2D to allow for easy porting of code across libraries.

## Code Example

This is an Example for a simple App using Wein2DAndroid.

This is the main activity that's defined in the AndroidManifest.xml:

```java

import devtaube.wein2dandroid.*;

public class ExampleProgram extends Wein2DApplication

{

    // cube values (feel free to play with these!)

    static final double CUBE_SIZE = 50.0; // the width and height of the cube (in pixels)

    static final double CUBE_JUMP_VELOCITY = 800.0; // the cube's jump velocity (in pixels per second)

    static final double CUBE_GRAVITATION = 1600.0; // gravitation (how much velocity gets removed per second)

    static final double CUBE_BOUNCEBACK_MULTIPLIER = 0.4; // how much velocity the cube keeps after hitting the ground

    double cubeHeight = 0.0;

    double cubeVelocity = 0.0;

    @Override

    public void onCreate()

    {

    }

    @Override

    public void onFrame()

    {

        // update calls //////////////////////////////////////////////////

        // if screen is tapped, set the cubes velocity (let the cube jump up)

        if(getMouseL()) cubeVelocity = CUBE_JUMP_VELOCITY;

        // move the cube up and down according to it's velocity

        cubeHeight += cubeVelocity * this.deltaTime;

        // if the cube is not on the ground remove some of the cube's velocity (gravitation)

        if(cubeHeight > 0.0) cubeVelocity -= CUBE_GRAVITATION * this.deltaTime;

        // if the cube is below or on the ground, set him onto the ground, invert the cube's velocity (movement) and remove some of it's velocity

        if(cubeHeight <= 0.0) {

            cubeVelocity = -cubeVelocity * CUBE_BOUNCEBACK_MULTIPLIER;

            cubeHeight = 0.0;

        }

        // render calls //////////////////////////////////////////////////

        // fill the screen with blue

        fill(11, 138, 143);

        // draw the cube

        drawRectangle()

                .setPosition((this.width - CUBE_SIZE) / 2.0, this.height - CUBE_SIZE - cubeHeight) // draw at the center of the screen (x axis), draw at the cube's height (y axis)

                .setSize(CUBE_SIZE, CUBE_SIZE) // draw the cube with it's width and height

                .setColor(255, 255, 255, 255)

                .draw(); // draw!

    }

}

```
