JInput failing to detect joypads on linux.

[kevglass]

As you know, LWJGL input is now a wrapper round JInput. Got this report recently:

http://lwjgl.org/forum/viewtopic.php?t=1237?

Is there some special setup required on a linux box to enable JInput to work? If so, is there a setup guide somewhere (wiki) ?

Any chance of getting some of the log messages that jinput under linux spews out?

I suspect it has something to do with the fact that jinput looks under /dev/input for all the files, not /dev.

Each distro seems to layout /dev differently, just to confuse the issue.

I sence a patch to try reading /dev/input, then trying /dev for js devices if none are found in /dev/input.

I'd still like the logs to check

where are the logs kepts?

Thats up to javaws, it seems that there are a bunch of files in ~/.java/deployment/log under java 1.5

They are named nothing useful.

The distro in question did indeed have the /dev/js - jinput checking both just seem to make sense.. maybe even configurable?

Not to pile on the work - but would it possible to catch the case where /dev/whatever can't be found and throw a bespoke exception (UnableToFindTheSoddingDeviceException ? ) so that users could detect it and display a sensible message "Please Move Your Devices around and break your distro"

Updates done but not yet tested for checking /dev after /dev/input

First attempt at freeing some of the memory from the init processes

No longer read the 0th element if no device files are found.

No exception yet for kev

Are these builds available somewhere?

You pointed at me via IM but they don't seem to have natives in?

Hi

With the help of kappaOne the issue is known. I'm away this weekend, but I hope to look at it whilst away and commit changes monday.

Endolf

P.S.

Endolf, in case you are reading this over the weekend and have forgotten what the issue is, you are ignoring joysticks that don't have an event device with them.

P.P.S. was that intentional due to some nastyness with joysticks???

P.P.P.S. Take your gamepad with you to test over the weekend

Hi

I think it's done, I don't have a net con from linux in the hotel, so it'll have to wait till tonight for a build to be uploaded and tested.

Webstart demo updated

new d/l here

P.S. Expect it to sigsegv, if it does, please send me the whole output.

ok still failing to get the joypad detected properly but is moving a step closer to working, heres the latest output

oh btw no need to worry about uploading natives everytime now, cos i found a easy way to get native output when using java webstart, if you just run the jnlp through a console, native output comes on the console window and java webstart output on the java console.

Hi all,

I was trying JInput on Linux and came across this thread when trying to resolve the same problem. I noticed that the joystick appears to be detected, but not until my program has exited. I've got test code and its output, which I've attached to this post.

It was run on a Slackware 10.2 system with JDK 1.5.0_04 and one joystick on /dev/input/js0. I hope it helps.

Hi

New webstart version and new build here.

ok good news just tried JInput through JWS and it works

works great and detects all the buttons, however just one thing when i run the jws two windows pop up one with the title SAITEK Tournement Pad and another blank window with title Controller Read Test, is this normal?

good work on getting it up and running!

[chrisw1229]

Yes the 2 windows are normal from my experience.  The test program creates 1 window for each device it detects and one window as the main parent window.  So if you close the blank window it closes all the other ones and shutsdown the program.

[endolf]

Hi

Kev's spot on, it does indeed open a window per device and the main one. If it detects a mouse it will open 3 for that device, one for the main mouse, one for the ball and one for the buttons.

If you feel brave enough, compile a kernel with the event interface enabled and you mouse, keyboard, joystick, and anything else plugged in will show up. If you have a USB scanner with 3 buttons for example, jinput will detect it and allow you to use the buttons in a game

Endolf

[Jeff]

Yes thats normal.

Just my quick and crappy programming on the demo

The mainf rame is there so you can end the app by closing it.

Each controlelr then gets its own frame.

The new build works perfectly for me as well. Thanks!
