what is wrong with that?

[significantfrank]

it is my first time to use Jinput, and i can compile ControllerReadTest.java,but when i  run it.
it comes exception :
java.lang.UnsupportedClassVersionError: net/java/games/util/plugins/Plugins (Unsupported major.minor version 49.0)
so what is problem?
thx in advance.

Hi

This means that you used jdk 1.5 to compile the code, but are trying to run it on jdk 1.4 or less.

Check which jdk javac is from, and check your path variable to check which jre it's in.

All the binaries on the jinput.dev.java.net should be 1.4 now after Kevglass pointed out that I had built them with 1.5

endolf  could you tell me what is the problem?
thx

Hi

Thats an easy one, and common. The native library can't be found, make sure you add -Djava.library.path=<folder containing the jinput-dxplugin.dll> to your start script/command

HTH

[significantfrank]

i use the jre of 1.50,and get your recently release of Jinput.
and it works now,since i felt depressed and exhausting these days,now i feel better.
endolf,thanks for you help and your work on Jinput

[significantfrank]

endolf
sorry to bother you again.
is there some Jinput  API Specification? which tells what the classes mean and how the methods work. 
if there is some,could you post it?
thanx a lot

[Jeff]

There are Javadocs  in the code.

Thats about it outside of the brief readmes.

There are also some examples  around if you look through the threads here.

[endolf]

Hi

Sorry for the delay in replying, was busy getting married

Basic rundown

Get the ControllerEnvironment by calling getDefaultEnvironment(), this gives you the plugin for the environment. From that you can get your controllers

A controller in jinput is not just a device like a joystick/mouse/keyboard/gamepad, but may also be some *part* of a device. For example, there maybe a controller instance to represent a mouse, but this may have no components, it may be that it has instead 2 sub controllers, one for the ball, and one for the buttons.

A Component is an axis, a button, or a key. From the components you can get information about the component, like the value, whether it's absoulte or relative, if it's boolean or analog etc etc.

You must remember to poll the controllers, I recommend polling at least 50 times a second. If you don't poll frequently enough, you will fill up the underlying buffers and start losing input events.

HTH a little

Hey hey!  Congrats!  Gonan post pictures?

You must remember to poll the controllers, I recommend polling at least 50 times a second. If you don't poll frequently enough, you will fill up the underlying buffers and start losing input events.

Really?  Thats ugly.  Is that in the general Java code as opposed to to the plug-ins? If so do we want to thin kabout replacing them with ring-buffers?

[significantfrank]

wow~~~congratulations for your marry!
so i can guess you will be abscent here for some days,and have a nice honey-moon

and jeff, i cant see the javadoc in my downloading files.could you give some  valid link? thx

[endolf]

Hi

Pictures will no doubt appear at some point yes

The honey moon is in november, so you have me till then i'm afraid

The buffer problem is a directx issue, we can increase the buffer size as it's creation is controlled by the plugin, but the implementation isn't controllable, just it's size.

The javadoc can be got from the jinput site in the files section.

Endolf

 

[significantfrank]

so, why  your honey moon is postponed to november
another question.
my OS is a chinese system.when i used the controller.getName( ) and component.getName( ),i just can get some disorder code.
how can i resolve this problem? 

[endolf]

Hi

The honeymoon is in november because we have other things going on this month

The jinput package has in it some tests. Could you run net.java.games.input.test.ControllerTextTest for me? (it's in the jinput.jar)

Please either post the whole output, or put it on a website and link to it. I have an idea, but I'd like to check

Thanks

Endolf
