Number of players in this game may vary from one to four. In case of multiplayer everybody will get alternate chance to throw a ball. In this game 10 targets are kept vertically maximum of which should fall down after being hit by the ball.
Playstore Link: Bowling 3D
Difficulty level: Moderate
We find the centroid of the target, and then align the ball along the centroid, then we swipe it straight across the screen.
- Computer with MATLAB, ADB Tool and required drivers set up.
- An Android Device with the Bowling 3D game installed on it. (Turn on the Developer options for better visualization)
- USB data transfer cable.
Here's the step-wise tutorial to automate the game. The source code is avaiable here.
The following command instantaneously takes the screenshot of the connected device and stores it in the SD card following the specified path.
system(' adb shell screencap -p /sdcard/screen.png ');The following command pulls it from the SD card of the android device into the working system following the path specified
system(' adb pull /sdcard/screen.png ');The pulled image is stored in the form of a matrix of pixel values by the MATLAB.
The white colored targets are cropped and its centroid is calculated and the ball is moved horizontally using adb commands such that its centroid aligns with that of target and then it is swiped straight.
The following command moves the ball horizontally
system('adb shell input swipe x1 y1 x2 y1');where (x1,y1) is the centroid of the ball and x2 is the x coordinate of center of the target. Now when the ball is aligned, to move it straight towards the target it is swiped using the following commands.
system('adb shell input swipe x2 y1 x2 y2 ');y2 is the y coordinate of center of the target.
