On a quick scan I can’t see anything that jumps out … can you share the output from running with -Vruiverbose (as Chris described in earlier post … ~/src/SARndbox-2.5$ ./bin/SARndbox -uhm -fpv -Vruiverbose)
so that we can perhaps see if there’s anything reported there.
It might also be useful if you posted your “strange readouts in terminal”.

As to linking buttons – once implemented they will effectively appear as ‘keys’ to be assigned when pressed, and you will see the Tool Selection menu – use ‘Utility/Script Executor’. Image shared here https://drive.google.com/file/d/1O9EXaHaoqSs3Tjap-xMZQ0RMBYJir9l_/view?usp=sharing

I have attached the Vruiverbose readout. Not exactly sure what is on the readout but maybe on of you can see what I am doing wrong. I have linked the file for you to review.

Well it looks like the system is running though as expected. The only thing puzzling me is the vruiverbose output is referencing two windows defined in config, whilst the SARndbox.cfg file you have ( and there seem to be a few copies in your Google Drive files) references a single window. I guess the question is are you sure that the SARndbox.cfg file is the one from your /home/warren/.config/Vrui-4.5/Applications/SARndbox.cfg location?

On the Script Executor .. not sure if you meant to attach an image … What happens when you pres an unassigned key? what menu are you offered?

I apologize but I needed to revise this post:

Ok guys and girls,

I have went over and over my code and still cannot find why my USB encoder is not working. Is there any kind soul that will review my code and see where Im going wrong? Thank you so much in advance. The kids are getting anxious and there may be a mutany if I dont get it running right soon. 😉

Thanks,
Josh

Hi Josh, since you don’t have the “Script Executor” option in a menu when pushing the button, you probably have an older VRUI installed.

Assuming you have Linux and the display driver correctly installed, start fresh from Step 3 here: http://idav.ucdavis.edu/~okreylos/ResDev/SARndbox/SoftwareInstallation.html

This will install Vrui 4.5, which has the script executor built in (old versions of Vrui didn’t have this yet).

Patrick

edit – i see you do have 4.5

One small thing – your button numbers should probably start at Button0
A second thing – the file ~/src/SARndbox-2.5/etc/SARndbox.cfg should not be the same as ~/.config/Vrui-4.5/Applications/SARndbox.cfg ; it is a place you can put options like this:
```
# Configuration file for SARndbox application
# Copyright (c) 2016 Oliver Kreylos

section SARndbox
	section Camera
		# Configuration parameters for Kinect v1
		compressDepthFrames true
		smoothDepthFrames false
	endsection

	waterTableSize (400,300)
	waterSpeed 1.0
	waterMaxSteps 30
	rainStrength 0.25
	evaporationRate 0.0

	elevationRange (-40,25)
	rainElevationRange (25,100)
	
endsection
```

Also, a few more troubleshooting things to try:

1) Script Executor. The computer freezing when trying to run a script in my experience has been due to the path of the script not being correct – it tries to run a script that isn’t there, and the machine locks up.
– Test the script executor manually: With the program running, navigate a terminal to the ~/src/SARndbox-2.5/ folder (press F11 to exit fullscreen if needed) and type ./ToggleWeather.sh – This will run the script manually. Similarly you could try running a specific script in your ~/src/SARndbox-2.5/scripts/ folder
– It’s a little strange that you don’t get the script executor as an option in the menu.

2) USB encoder. One way to test whether the USB encoder is working is to see if you can assign a function (eg. global water etc) while the program is running, by simply pressing the buttons. First you need to comment out the button assignments in ~/.config/Vrui-4.5/Applications/SARndbox.cfg like so:
```
section Vrui
    section Desktop
        #Disable the Screen Saver
        inhibitScreenSaver true

        inputDeviceAdapterNames += (HIDAdapter)
        
        section HIDAdapter
            inputDeviceAdapterType HID
            inputDeviceNames (USBEncoder)

            section USBEncoder
                name USBEncoder
                deviceVendorProductId 0079:0006
                trackingDeviceName Mouse
            endsection
        endsection

        section MouseAdapter
            mouseIdleTimeout 5.0
        endsection

        section Window
            windowFullscreen true
        endsection

        section Tools
            toolClassNames += (ScriptExecutorTool)

           # section DefaultTools
           #     section WaterTool
           #         toolClass GlobalWaterTool
           #         bindings ((USBEncoder, Button0, Button1))
           #     endsection

	   #     section ChangeWeather
	   #          toolClass ScriptExecutorTool
	   #          bindings ((USBEncoder, Button2))
	   #          executablePathName ~/src/SARndbox-2.5/ToggleWeather.sh
	   #          arguments ()
           #     endsection
           #  endsection
        endsection
    endsection
endsection        
```
If when you press a button you get a menu, the USBEncoder is working.

Agree the steps from tuchwando … though might I suggest that because ScroptExecutor isn’t there, it really would be a plan to re-install Vrui – if not bite the bullet and start afresh with a new clean version of the build
