Especially because the input devices are entirely different. There should be a mapping, before queuing control events, that would convert swipes and taps into meaningful synthetic keystrokes and mouse movements and clicks that the current game code would understand. This mapping is were the "feel" of the game would be defined. > The "W_" API presumes too much about the input devices and the > underlying graphics libraries. Yes, this would be the hard part. The API should be divided into 2 modules, one for Graphics in open GL, common to all platforms and the other for the input event handling, particular to each platform. I will focus on the "W_" module. I guess that I should look at both unix and win implementations to get more insight.
