== 2007-07-08 (Sunday) - key mapping == | |||
Now, that I've been looking through the backends implementation for a couple of days, I got a pretty good understanding of how they work. I am ready to start implementing my tasks on backends' refactoring. So, as agreed with sev, the first feature to be implemented is key mapping. Yesterday and today I was closely reviewing the current implementation of key mapping. | |||
So, key mapping is used to convert key codes to other key codes which in turn are mapped to certain game actions. Key mapping takes place in the pollEvent functions of the backend OSystem classes. The actual device specific mapping is done through the Actions classes like CEActionsSmartphone. Currently only wince supports user key mapping dialogs. | |||
In general key mapping is implemeted in wince, symbian, ds, and palm backends. Wince and symbian provide the best implementations. | |||
