Keyboard, Mouse and Touch news

December 10, 2013 posted by: Elias

There’s been another update to the mouse and keyboard nodes before but that turned out to still cause troubles:

  • key presses could still be missed (think: typing too fast on typewriter)
  • global keyboard didn’t work properly with all applications
  • mousewheel didn’t work globally
  • no nodes to deal with touch devices (2013! hellooo!)

Now there’ve been notable contributions to work around some of those issues, like windowstouchbeta-contribution, global-keyhookbeta-contribution and directinput-(devices)beta-contribution but those being really basic things we thought we’d give it another shot.

So here is what you get:

  • Keyboard and Mouse nodes in variants: Desktop (was: Global) and Windows
  • where Keyboard and Mouse (Desktop) are spreadable (ie. understanding multiple keyboards/mice attached. quite nerdy, what you think?)
  • a new Touch (Devices Window) node
  • all those nodes come with a Queue Modepin to distinguish Enqueue (don’t miss anything) and Discard (just take the latest) modes
  • KeyStates, MouseStates and TouchStates split-nodes (for comfortable use in subpatches)
  • KeyEvents, MouseEvents and TouchEvents split-nodes (allowing for advanced … stuff)
  • join-nodes for some of them

like so:

Device typeSource nodesSink nodes
KeyboardKeyboard (Devices Window)
Keyboard (Devices Desktop)
KeyEvents (Keyboard Join)KeyEvents (Keyboard Split)
KeyStates (Keyboard Split)
MouseMouse (Devices Window)
Mouse (Devices Desktop)
MouseEvents (Mouse Join)
MouseStates (Mouse Join)MouseEvents (Mouse Split)
MouseStates (Mouse Split)
TouchTouch (Devices)TouchEvents (Touch Split)
TouchStates (Touch Split)

For the plugin-developer:

  • Plugins that are using the (now) legacy “KeyboardState” and “MouseState” datatype don’t need to be modified - vvvv is gracefully taking care of this with an auto-wrapper.
  • The new “Device” datatype merely is a wrapper around a push based sequence of Device notifications. See KeyboardNodes.cs for an example of how to use it in your new developments.

all available now for testing with the latest alpha builds
