99. As the device rotates around, the needle will move as well, indicating the current direction. This feature might not work correctly in all simulators and an actual device may be needed. See Also jQuery Rotate Plug-In 24 | The Recipes Using the Accelerometer to Detect Motion Problem You want to detect the motion of the device as it moves. 0 and above are able to detect the device’s current x, y, and z axis movements. getCurrentAcceleration function. clearWatch function allows you to turn off receiving the updates.
First, drawImage clears the canvas’s screen; then it draws the image of the ball on screen in the new x, y coordinates that were calculated in the moveBall function. drawImage function, you can read this article I wrote when experimenting with the tag to create a walking animation using an image sprite. If there was an error detecting the acceleration, the stopBall function is called. clearWatch function. An alert dialog box appears as well to inform the user of the error. This code is an excellent start to creating a labyrinthine game using the device’s motion sensors.
