Continously stream image data to the display about gamesense-sdk

[JHunz]

I think the problem is that the code that converts JSON back to lisp is treating the image data as a list rather than specifically as a bytearray, and the GameSense API is being too strict about what it accepts. for now the following should work better as a handler:

(handler "IMAGE" (lambda (data) (on-device 'screened show-image: (list-to-bytearray (image-data: (frame: data))))))

We'll update the API in a future release to allow lists as well, so that extra conversion doesn't need to be included

[JHunz]

Can I confirm a couple things about the way you have this set up?

1. This is intended to be real-time rendering, rather than precalculated? So calculating all your frame data in advance is not an option?
2. Are you trying to do this by rebinding the handler for the rendering event with new info in the image-data key each time?

[Faleij]

1. Yes
2. Yes

[JHunz]

Okay, so the problem is that rebinding the handler is causing GameSense to be reinitialized for that game (to force current versions of all handlers), which is what is causing the stock image to be momentarily displayed. What you need to be able to do is pull image data from what you send with the event without rebinding the handler. You can't do this purely with the JSON handler setup.

Luckily for you, we recently added an endpoint for binding GoLisp handlers for developers (including ourselves) who want to do fancier things than what is possible via the JSON API. Unfortunately, we haven't gotten around to updating the documentation yet for it.

Until we do (hopefully very soon, now that someone needs it), here's the general setup:

1. When you send your event, in addition to sending a "value" key, also send a "frame" key with some subkey containing your image data.
2. Write the code for a GoLisp handler that passes the image data from the context frame directly into the GameSense calls for sending image data. Assuming your event is named "IMAGE" and your data subkey is "image-data", it will look something like this:

    (handler "IMAGE" (lambda (data) (on-device 'screened show-image-on-zone: (image-data: (frame: data)) 'one)))

3. Binding this handler once on program startup by posting to the /load_golisp_handlers endpoint with the data {"game": <gamename>, "golisp": <the code above, as a properly JSON-escaped string>}

Hopefully that's clear enough. We'll try to get the documentation updated shortly

[Faleij]

Thank you. However I can not get this to work. It seems that load_golisp_handlers is not loading the handlers - I can't see any event handler in the GUI and it is not updating the display. I have tried to load other golisp event handlers via /load_golisp_handlers but I can't get any reaction from the mouse. I am on version 3.9.0
Do I need to do anything besides registering the game, load the lisp handler and send events? Am I missing something?

// response from /load_golisp_handlers
{"load_golisp_handlers": {"game":"EXAMPLE_TEST","golisp":"(handler \"IMAGE\" (lambda (data) (on-device 'screened show-image-on-zone: (image-data: (frame: data)) 'one)))"}}

// response from /game_event
{"game_event": {"level":"","game":"EXAMPLE_TEST","event":"IMAGE","Data":"{\"frame\":{\"image-data\":[128,0,0,0, ...]},"value":0}}}

[JHunz]

in the game_event response, I notice the d in Data is capitalized. I'm pretty sure the JSON unmarshaling is case-sensitive.

[Faleij]

That's the response I get from the API, this is what I send:

{"game":"EXAMPLE_TEST","event":"IMAGE","data":{"value":0,"frame":{"image-data":[128,0,0,0, ...]}}}

I can't do anything regarding the response, it's SteelSeries Engines response. The response I get I don't process in any manner so it does not matter to me that D is capitalized. I have always been getting capitalized D in the response, it has not hindered any functionality as far as am I am aware.

[JHunz]

Are there any errors in your golisp log? Assuming you are on Windows, it should be located in %PROGRAMDATA%/SteelSeries/SteelSeries Engine 3/Logs

[Faleij]

There are tons of errors, 1,7mb of errors. Latest of them:

[ToadKing]

There is a small typo in the example posted. Try this instead:

(handler "IMAGE" (lambda (data) (on-device 'screened show-image-on-zone: (image-data: (frame: data)) one:)))

Alternatively, this should also work for the Rival 700.

(handler "IMAGE" (lambda (data) (on-device 'screened show-image: (image-data: (frame: data)))))

It looks like it's still using the old handler code. This appears to be a bug in our Engine code.

My apologies for this. This has only been used internally so far and appears to still have some bugs. Deleting the example_test.lsp file from %PROGRAMDATA%/SteelSeries/SteelSeries Engine 3/games and restarting Engine should fix it. I'll file a bug for the issue you're having and see if it can get a fix in a future release.

It seem to have loaded the new code as I am not getting any errors in the logs, there's no new entry in any of the log files, however I am still not seeing any image on the display.

[JHunz]

In the data you send with the event, can you try incrementing the value every time instead of continuously sending 0? I think the caching mechanism (to prevent constant writes) may be working against you in this case. Although I would have expected at least the first image to have been written

[Faleij]

Incrementing value does not make a difference. Still no image with neither show-image-on-zone nor show-image.

Side-note: I am able to display text using a lisp handler with show-text.

[ToadKing]

Do you have an example of the exact event data you're sending (the full JSON payload)? It's possible the image is getting rejected for being the wrong format.
