Mobile gaming is a big trend recently. Adobe has been working on putting full feature Flash player into mobile devices. Smartphone that runs android can use the Flash player 10.1. This makes it possible to extend our virtual world into any android mobile device. However, usually we cannot give users a good experience by directly playing the Flash games in mobile phone without any optimization. There are several limitations that we need to consider for running Flash in mobile devices.
The screen size of the mobile devices is usually very small compared to the desktop. It may range from 480x320 to 800x600. We cannot simply scale down everything to fit the screen size. All elements should be of a reasonable size so that they are recognizeable and can be touched. If the buttons are so small that the players can't touch them correctly, it will be useless.
RAM in mobile devices is often very low. We need to make sure we do not allocate a large block of RAM because it may make the system unstable or even crash.
The CPU in mobile is designed to run in low speed and consume less power for longer battery usage. We should avoid heavy loading of the CPU when designing the mobile version.
Flash virtual world establishes a connection with the socket server. The network bandwidth of the mobile network is an issue if the players does not have the unlimited data plan. We should at least warn the players of the high usage of the data plan network bandwidth on mobile phones.
Smart phone is becoming a new gaming platform. Porting the virtual world into mobile devices can encourage players to interact with friends inside the virtual world while they are on bus or sitting in café. The seamless integration of both mobile and desktop versions can help keeping players return to the virtual world.
