Is there a way to add a simulink block programmatically from within a function? The principle works by using add_block(...) via script in the basic matlab workspace. But if i try to add a block from within a function, Matlab seems to dont see the simulink model anymore. I get the error Invalid destination block specification.
Any clue what to do? Thanks.
EDIT: This add_block('built-in/Gain','Model/blk') worksin the command window, but it doesnt work inside a function.
Got it finally working, just had to change the current workspace. evalin('Base',...) does the trick.

I have a sample.png file which is being changed outside godot
and after it's modified, godot recives a signal and when that signal is received
I want that specific sample.png file to be reimported
I tried this answer but I want to reimport in my script itself not create a plugin for it
(atleast that's what I'm assuming it does)
I also tried this from the documents but I'm not sure how to use it exactly
EditorFileSystem.update_file("res://Assets/sample.png")
so how do I achieve the desired result?
The class EditorFileSystem is intended for plugins.
You would call get_editor_interface() from an EditorPlugin (which would be where you would be writing code if you were making a plugin). And that gives you an EditorInterface object, on which you can call get_resource_filesystem() which gives you an EditorFileSystem object.
So the intended use is something like this:
extends EditorPlugin
func example() -> void:
var editor_file_system := get_editor_interface().get_resource_filesystem()
editor_file_system.scan_sources()
# editor_file_system.update_file("res://icon.png")
By the way, EditorInterface also has a filesystem_changed signal. Although I don't know how reliable it is.
Usually you don't have to do that. When you restore the Godot window, it will scan for changes in the project folder. So you might minimize Godot while you are working on something else and when you bring the Godot window back it will pick on the changes.
In practice, the only situations when I had to use scan or scan_sources was when I had a tool script that write a resource file which should be imported, and I wanted it to reflect right away.
Instead of making a custom plugin, I'll remind you that form a tool script (as long as it is running in the editor) you can simply create an EditorPlugin object. For example:
var ep = EditorPlugin.new()
ep.get_editor_interface().get_resource_filesystem().scan()
ep.free()
I had also shared this example in another answer I wrote for you a while back here, it is under the title "About saving resources from tool scripts".
Repo for all code I've been using is updated here . When I run the requestor script it exits with a runtime error 2 (File not found). I am not sure how to further debug this or fix it. So far I've converted my code over to a python slim docker image to better mirror the example. It also works for me when I spin up a docker image that typing and running "/golem/work/imageclassifier.py --trainmodel" works from root. I switched all my code to use absolute paths. I also did make sure the shebang (#!) uses linux end of file characters rather than windows before which was giving me errors. Fixed a bug where my script returns error code 2 when called with no args to now pass.
clf.fit(trainDataGlobal, trainLabelsGlobal)
pkl_file = "classifier.pkl"
with open(pkl_file, 'wb') as file:
pickle.dump(clf, file)
is the only piece I could think of that causes the issue, but as far as I can tell this is the proper way to pickle something in python. Requestor script is also heavily based on the simple service example and I tried to mirror my design to that. I just need help in getting more information while debugging, or guidance on how to move forward from here
i'm trying to do some stuff in vbscript, and i have to take a screenshot of the screen. I don't want to use an external executable (Auto Screenshot using VBS).
I find a vbs which can be nice (how to take screenshot by vbscript?) but when i use this, it use an object (Sys), but i don't know how to create it.
I find some resources here, but i really don't know how to initiate the object "Sys", apparently it's like already "in" the vbscript, but it doesn't works for me.
I tried some stuff (Set Sys = CreateObject("System") or things like that, but nothing works :(
I hope you'll find something ^^
The question you've referenced looks like a low-quality question. The references to "Sys" that you see appear to be in a product called TestComplete. See How to capture a screenshot using VBScript in TestComplete? You'd need to acquire and install TestComplete to use it, or find another program to capture screenshots instead.
What I mean by this is:
I have a program. The end user is currently using it. I submit a new piece of source code and expect it to run as if it were always there?
I can't find an answer that specifically answers the point.
I'd like to be able to say, "extend" or add new features (rather than fix something that's already there on the fly) to the program without requiring a termination of the program (eg. Restart or exit).
Yes, you can definitely do that in python.
Although, it opens a security hole, so be very careful.
You can easily do this by setting up a "loader" class that can collect the source code you want it to use and then call the exec builtin function, just pass some python source code in and it will be evaluated.

Inside a GUI that I have made using GUIDE in Matlab. I run into a problem where upon using the Load() function to load a .MAT file all my handles change values. This means that if I had a button that I wanted to use on my GUI. My program will believe its handle is for example
handles.button1 =190.082
when in reality the only way I can access that button any more is through a different handle that is unknown. So if its unknown lets see what its new handle must be.
findobj('Tag','button1') = 227.0093
As you can see these numbers are completely different. Why the handles values get changed is beyond me. Since the handles change I can no longer use the set() function as I have written in previous sections of code. For example I have to change
set(handles.button1, 'Enable', 'off');
to
set(findobj('Tag','button1'),'Enable','off');
Does anyone have an explanation as to why this problem occurs when using Load()?
Is there a feasible solution instead of having to find the handle for an object every time you want to use it?
The .MAT file conveniently also had a handles variable in it which overwrote my current handles.
