Description

GameX was developed by Hayes Haugen and performs same function as Gapi for earlier CE2.11 machines.
The goal of GameX game development library is to solve the problems that are encountered when trying to write performance-oriented, real-time games on Windows CE devices. It is also useful for other applications that need to use the CE device in a way that isn’t supported by the operating system.

- GameX is a single object.
- If you want to support different rotations then you need to factor that into your draw code and your button code. Duh.
- Use GetASyncKeyState() for detecting PSPC button presses in all but the simplest of cases. The OEM’s keyboard driver handles message generation for these buttons and is different from device to device. The messages oftentimes don’t make sense, there will only be a KEYUP message when the button is pressed but no other messages. Some devices delay the messages approximately 1 second, others won’t generate messages for buttons when one button is held down.
- Many devices will have 16 bit or 8 bit color but similar frame buffer memory bandwidth as a 2 bit monochrome device. (include timings). You can’t even clear the screen 30 times a second on many devices, let alone get a game to run that fast. Hopefully GameX and games in general on CE will encourage CE manufacturers to improve their hardware in this area.
- Currently to determine if a device has support for direct frame buffer access use GetFBAddress(). A NULL return value means it doesn’t.
- I want to expand BeginDraw() so that if you call it with BeginDraw(true) it will check if it’s OK to draw to the FB first (is app frontmost).
- Use the IsPSPC(), HasKeyboard(), etc. API calls. This is usually the question you need answered and GameX can evolve in how it answers it. For example: external keyboards are starting to become more common – if your code always assumes PSPCs don’t have keyboards then the user with the external keyboard is out of luck.
- Still lots more to do!
