B)You can either directly send a keyboard, mouse, or other message to the game process by determining that obstacles, monsters, and other things on the map have crossed the map. Of course, killing monsters is done by simulating buttons.
However, with the destructive impact of plug-ins on the game, anti-plug-ins and plug-ins have been entangled in the kernel layer, such:

The wince application was started two years ago. However, due to division of labor, there has never been a chance to gain a deep understanding of the development of the wince Driver (including Pb-related system customization ). If it weren't for the fakegps development work that was scheduled by Ma Ning some time ago, I really don't know when to understand the wince driver development.
Fakegps is a disguise
