Note that joystick motion events may batch multiple movement samples together within a single object. The MotionEvent object contains the current position for each joystick axis as well as multiple historical positions for each axis.
The historical values for an axis consists of the set of distinct values older than the current axis value, and more recent than values reported in any previous motion events. See the MotionEvent reference for details. You can use the historical information to more accurately render a game object's movement based on the joystick input. You can also find the number of historical points in the joystick event by calling getHistorySize.
The following snippet shows how you might override the onGenericMotionEvent callback to process joystick input. You should first process the historical values for an axis, then process its current position. Before using joystick input, you need to determine if the joystick is centered, then calculate its axis movements accordingly. Joysticks typically have a flat area, that is, a range of values near the 0,0 coordinate at which the axis is considered to be centered.
If the axis value reported by Android falls within the flat area, you should treat the controller to be at rest that is, motionless along both axes. The snippet below shows a helper method that calculates the movement along each axis.
You invoke this helper in the processJoystickInput method described further below. To support game controllers that have more sophisticated features beyond a single joystick, follow these best practices:.

This app is for those who has two types of bluetooth module and dont want to download each app specifically for that BT module. This app makes you control your Arduino projects like RC car or any IOT applications using your mobile phone thru bluetooth. This app is under beta test.
Any bugs or error can be reported or send to my email. Check the provided Schematic Fritzing for connections. Up to 18 channels D2-A5 Relay can be used.
Using relay you can control your lights i. Using this controller you can control your RC car forward, Turnleft, turnright, backward etc. Keysticks runs on Windows. A suggested minimum specification of computer is as follows:. You can use any gamepad or joystick that supports either XInput or DirectInput which most do and is correctly installed i.
If you already use your controller with your computer, you can probably use Keysticks with it. If you have a wireless controller, you may well need a Wireless Gaming Receiver plugged into a USB port, as shown in the picture below. Using Keysticks with a wireless controller. In any case, with the help of the Android standard information strategy, we have effectively ready to make our PDA as Joystick.
Presently, utilizing your Android-based mobile phone, with the help of Wi-Fi or Bluetooth, it will go about as a gamepad and play your game from the particular distance utilizing your mobile phone.
Your Android mobile phone will go about as a gamepad and the controlling capacities will be transmitted through the wireless technology. On the off chance that we need to play PC enabled game, at that point we need to buy USB based gamepad or Bluetooth enabled gamepad.
Again in a Bluetooth enabled gamepad, if there is the issue with Bluetooth, your gamepad goes in vein. We need to do different manual settings and another software installation to utilize this wireless system over our system.
