A solution for devices that don't offer the touch.getSize() function, you can have on the start screen a high resolution plot of 2d points. 对于不提供touch.getSize（）函数的设备的解决方案，您可以在开始屏幕上获得2d点的高分辨率图。 On touch, detect the ones touched and there you can have a pretty accurate area of how big the finger is. 在触摸时，检测触摸的那些，在那里你可以有一个相当精确的手指有多大的区域。
