```

## v1.1.0 BREAKING CHANGE!

* Made changes to JoyStickListener
  * Added Direction to onMove
  * Added Event calls for onTap and onDoubleTap

## Defaults:

1. Background = White
2. Button = Red
3. Button Radius = 25%
4. StayPut = false
5. Directional-Axis = 8

## Setup:

```xml
<com.erz.joysticklibrary.JoyStick
  android:id="@+id/joy1"
  android:layout_width="200dp"
  android:layout_height="200dp"
  android:layout_gravity="bottom"/>

<!-- default 25: radius percentage of full size of the view between 25% and 50% -->
<com.erz.joysticklibrary.JoyStick
    android:id="@+id/joy2"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:layout_gravity="bottom|right"
    app:padColor="#55ffffff"
    app:buttonColor="#55ff0000"
    app:stayPut="true"
    app:percentage="25"
    app:backgroundDrawable="R.drawable.background"
    app:buttonDrawable="R.drawable.button"/>
```

```java
JoyStick joyStick = findViewById(R.id.joyStick);

//or 

JoyStick joyStick = new JoyStick(context);
```

## JoyStickListener:

```java
//JoyStickListener Interface
public interface JoyStickListener {
        void onMove(JoyStick joyStick, double angle, double power, int direction);
        void onTap();
        void onDoubleTap();
}

//Set JoyStickListener
joyStick.setListener(this);
```
1. onMove: gets called everytime theres a touch interaction
2. onTap: gets called onSingleTapConfirmed
3. onDoubleTap: gets called onDoubleTap

## Directions:
1. DIRECTION_CENTER = -1
2. DIRECTION_LEFT = 0
3. DIRECTION_LEFT_UP = 1
4. DIRECTION_UP = 2
5. DIRECTION_UP_RIGHT = 3 
6. DIRECTION_RIGHT = 4
7. DIRECTION_RIGHT_DOWN = 5 
8. DIRECTION_DOWN = 6
9. DIRECTION_DOWN_LEFT = 7

To get JoyStick direction you can use

```java
joyStick.getDirection();
```
or get it from the JoyStickListener

## Axis Types:
1. TYPE_8_AXIS 
2. TYPE_4_AXIS 
3. TYPE_2_AXIS_LEFT_RIGHT 
4. TYPE_2_AXIS_UP_DOWN

To set Axis Type:

```java
joyStick.setType(JoyStick.TYPE_4_AXIS);
```

## Getters/Setters

```java
//Set GamePad Color
joyStick.setPadColor(Color.BLACK);

//Set Button Color
joyStick.setButtonColor(Color.RED);

//Set Background Image
joyStick.setPadBackground(resId);

//Set Button Image
joyStick.setButtonDrawable(resId);

//Set Button Scale
joyStick.setButtonRadiusScale(scale);

//Enable Button to Stay Put
joyStick.enableStayPut(enable);

//Get Power

```
