Hello,
I am thinking about adding two buttons for draining and raining instead of using keyboard. Do I need to use a microcontroller like raspberry pi to detect the button press or I can do that by modifying the file in AR sandbox? Can you give me some ideas of coding please?
Thanks
Faye

Oliver had a post on the old forum that uses an arcade USB encoder to send standard keyboard keys when the “arcade” buttons are pressed. He includes instructions for configuring the sandbox to use the buttons.

The Wayback Machine has his post for “USB Button Solution”, but I cannot include the URL.

Also, there are USB keyboards with one, two, five, etc. buttons. This way, the only sandbox setup is to assign tools (drain/rain) in the configuration file. I do not know how the output values are assigned to the keys, but I suspect it requires Windows for the initial setup.

Another example is Liudr’s AR Sandbox controller. He gives instructions for building flood and drain buttons using an Arduino microcontroller.

I found the wayback machine post, and was wondering if anyone had a source for the specified code files: ScriptExecutorTool.h and ScriptExecutorTool.cpp

@mattdc Thank you for adding the link. That’s the post I was referring to.

It looks like the ScriptExecutorTool source files were added to Vrui
after the 4.2 release. They can be found under the directory where the Vrui 8.0 source was unzipped, in Vrui/Tools/ScriptExecutorTool.h and
Vrui/Tools/ScriptExecutorTool.cpp.

Great, thanks for the update. I went ahead and wired up an arduino and some buttons. It seems to be working perfectly fine without crashing anything.

I just wanted to add my config file that I use with a simple arcade button USB Adaptor combo.
```
section Vrui
    section Desktop
        section MouseAdapter
            mouseIdleTimeout 5.0
        endsection

       
        inputDeviceAdapterNames += (HIDAdapter)
       
        section HIDAdapter
            inputDeviceAdapterType HID
            inputDeviceNames (USBEncoder)
            
            section USBEncoder
                name USBEncoder
                deviceVendorProductId 0079:0006
                trackingDeviceName Mouse
            endsection
        endsection

        section Window
            windowFullscreen false
        endsection
        
        section Tools

        toolClassNames += (ScriptExecutorTool)  

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

            endsection
        endsection
    endsection
endsection
