Input via socket

Questions
#1

I’m new to Defold, please excuse if the answer is obvious, but I couldn’t find anything.

How could I create input (with permanent update of action.x, action.y for a start) from data received via network? I would like to experiment with hand position detected by YOLOv7, which comes as a stream of UDP packages. I found the examples for receiving data from network, but I somehow miss how I can trigger input events of a gameobject.

Many thanks!

I don’t know the best way to communicate with UDP through a socket.
It should be possible I guess.

For the input itself, there is no way to add input events from Lua.
I suggest that you call a function with the input coordinate: handle_input(x, y)

To make sure I understand, you mean, I shall save the x,y position somwhere, and in my functionupdate(self, dt) I call handle_input(x, y) to react on the changed coordinates?

#4

Well, it depends on how you handle the data coming from the stream?
You still need to poll the data from the socket.
That might be a good place to call the handler.
But you could also save the info for later.

#5

ok, I get it, then I will try out how to do the socket handling, and after this decide how to do the rest.
Any case, it sounds easy, which is great :slight_smile:

Thank you so much.

If you need some help setting up the UDP socket in Defold you can take a look here:

(I haven’t worked with the code above in quite some time but it should be up to date and working still!)

this is where I will start from :grinning: very much look forward to dive deeper in Defold
Thank you!
