[2021:13610] Bug: Script TOP copyNumpyArray does not trigger cook downstream

[nettoyeur]

build: 2021.13610

copyNumpyArray in the Script TOP does not trigger a cook downstream in nodes that ask for its data.

Example attached
scriptTOP_copyNumpyArray_does_not_trigger_cook.tox (1.1 KB)

PS perhaps this is an RFE instead of a bug? not sure

Hi.
The Script methods are intended to be used only during the onCook callback.
You should include all variations inside that callback and execute accordingly.
I’ve updated the online doc.
Sorry about the confusion.

Cheers,
Rob.

hey @rob, thanks for the info.
Actually so far I have only used it by calling the copyNumpyArray method from an extension, where I use the Script TOP as a way to write incoming data from external APIs.
I don’t really see any way I could to this in the onCook callback, so I work around it by calling
op("myScriptTOP").cook(force=True)
after each call to copyNumpyArray.

FYI this is also the way others are using it, see these threads linked below. So far I answer all of them to use the forced cooking method and that seems to make everyone happy

Engine Comp doesn't show/update TOP output for TCP DAT -> Script TOP toy example?

Hello there, I have a Engine Comp which contains a tcp dat which is copying raw bytes to a script top. When I use these in a container on their own I can send the script top’s texture to an out and it contains the data as pixels that I’m sending from my server. The issue comes when I export that container to a .tox file and try to put it into an engine comp. I’ve included a couple of other OP outputs to ensure that the issue is specific to the script top. Has anyone run into this issue before? …

Dynamically changing alpha of script top won't update a subsequent reorder node to which it connects

I have a reorder node input one is a noise top input two is a script top r,g,b come from input 1 alpha comes from input 2 if I change dynamically the alpha of the script top via code, the reorder node will not update automatically and yet I need to use the script top for sure but i need to get the r,g,b from a separate node, how can I do that then? thank you

@rob @nettoyeur yes what about cases like this one: Im receiving stream data on a webClient operator on the onResponse function and I need to then update the scriptTOP so I need to do it from outside the onCook callback of the scriptTOP, and force the scriptTOP to recook

I’ve proposed a solution on the other thread:

FIXED: Updating a scriptTOP, errors when trying to dynamically update the TOP from python

@nettoyeur a very important question, I will need to update the top whenever I receive streaming data from a flask python API. I receive the data in here: def onResponse(webClientDAT, statusCode, headerDict, data): … which is code that is outside of the scriptTOP dat, will I be able to update that numpy array from there? thank you
