Joypad view simulates a Joystick for interactive applications.
Add repository to build.gradle:
repositories {
// ...
maven { url "https://jitpack.io" }
}
Add the dependency:
dependencies {
compile 'com.github.eigenein:joypad-android:5'
}
<ninja.eigenein.joypad.JoypadView
android:id="@+id/joypad"
android:layout_width="200dp"
android:layout_height="200dp"/>When user interacts with Joypad then onUp and onMove events are fired.
final JoypadView joypadView = (JoypadView)view.findViewById(R.id.joypad);
joypadView.setListener(new JoypadView.Listener() {
@Override
public void onUp() {
textView.setText(R.string.text_view_up);
}
@Override
public void onMove(final float distance, final float dx, final float dy) {
textView.setText(getString(R.string.text_view_move, distance, dx, dy));
}
});distance varies between 0f and 1f while dx and dy vary between -1f and +1f.
One can configure inner circle color, outer circle color, moveable circle color and direction triangles color:
<ninja.eigenein.joypad.JoypadView
android:layout_width="200dp"
android:layout_height="200dp"
app:outer_color="@color/grey_800"
app:moveable_color="@color/blue_500"
app:directions_color="@color/blue_900"
app:inner_color="@color/blue_800"/>One can also configure inner circle radius, outer circle width and moveable circle radius by setting inner_radius, outer_width and moveable_radius attributes.
There is the utility class WheelsPower that converts distance and offset into relative power for left and right wheels of some vehicle:
final WheelsPower wheelsPower = WheelsPower.wheelsPower(distance, dx, dy);
// wheelsPower.getLeft() and wheelsPower.getRight() vary from -1 to +1.The MIT License (MIT)
