Touch inputs in gamma

[willi_tsb]

Hi people :)
I just need a quick update on TouchsStates in Gamma…
Is there any way by now to handle touch inputs inside Gamma without the use of Beta features?

[joreg]

as of now touch is only available via VL.Stride windows. ie you need to get the latest 2020.3 preview.

then you have an experimental Touch node:

beware that the touch ID is 0 for all touches. so if you need a consistent id for touches, for now you’ll have to use VL.TrackObjects which can follow the touchpoints and assign them an id.

Ah ok, thank you for the quick anwser @joreg :)
I’m just asking, because i try to create a ui with elementa/ skia… i imagine that a workaround for this could be a stride renderer with the ui as a texture in it. In this case the render window needs to be of the same size as the texture… or is there a better option?

[joreg]

the good news: you can render elementa directly into a stride window, without the need to go via a texture:

i am not sure though if you can use touch input with elementa yet. @dottore @sebescudie?

[dottore]

touch is not implemented in elementa yet, since we’re relying on Skia notification

If you only need single touch you can use something like Input Simulator:

Inject multitouch events

If single touch / mouse emulation is sufficient you can try Inputsimulator. I used it recently with LeapMotion and it works quite nicely. There are also: https://www.nuget.org/packages/TCD.System.TouchInjection https://www.nuget.org/packages/Nukepayload2.Diagnostics.InputInjection

Thanks everyone for the very helpful replies :)
I will try out @bjoern 's option as i only need single touch… but really looking forward to a touch implementation in Skia/ Elementa.

hey guys, also looking for a solution to get simple touch events. tried to come along with the Inputsimulator , but not being very successful so far.

@bjoern or @willi_tsb would you be up for sharing your achievements? big thanks in advance

Stride has touch input, check the help patches…

[willi_tsb]

I’ m using a workaround which combines touch from stride and skia mousestate… isn’ t probably the best solution and it can be a bit confusing if mouse and touch inputs need to be frame synced… but to get just touch events use stride ;)

@tonfilm @willi_tsb thanks guys! up and running

Upcoming preview builds will have touch support for the normal Skia renderer as well.

@Elias hurray, hope we will be able to touch VL interface also ;)
