Joystick deadzone investigation #22

Open rdoeffinger opened 4 years ago

rdoeffinger commented 4 years ago

Some joysticks seem to have issue with e.g. drifting if the in-game deadzone handling is patched out. It is of course possible to just leave that enabled by default, but it generally seems too extreme by default and makes it hard to aim for anyone with good joysticks. So this ticket is meant for collecting data on different joysticks/gamepads to see if there is a reasonable compromise. To collect data run the JoystickStats.exe file (download from release page: https://github.com/rdoeffinger/xwa_ddraw_d3d11/releases/download/v1.5.13/JoystickStats.exe ). Move the joystick, then let it return to center position and press button/"A" button. Let it run for a bit without moving the joystick and copy-paste the output line (to copy press Ctrl+M, mark text, press enter). Example for my Logitech Extreme 3D pro: Try 1: winmm: 32511,32767 min: 32511,32767 max:32511,32767

Try 2: winmm: 32767,32767 min: 32767,32767 max:32767,32767

Try 3: winmm: 32767,32511 min: 32767,32511 max:32767,32511

As you can see, normally the position is stable once the joystick is in center (min and max are the same), however it doesn't always return to exact center but is a bit above 200 units (less than 1% as it uses the full 0 to 65535 range) off.

Thanks for your contributions, it's very helpful. It might take a while longer before I get around to do something with it though!

T16000m FCS

Try 1: winmm: 32767,32767 min: 32767,32767 max:32767,32767 Try 2: winmm: 32767,32767 min: 32767,32767 max:32767,32767 Try 3: winmm: 32767,32767 min: 32767,32767 max:32767,32767

It seems always exact.

I'd love to know if there was away to patch away the hard coded dead zone in old TieFighter 1995 CD version (steam). As much as I like the improved XWA graphics, I love to play the old original pixel art and the better midi sound of the 1995 CD version.
