            Looping over the properties of Views (struct) in an Array is returning wrong values (init values)
            Asked 2022-Mar-31 at 21:09

            I am using an array of Label-Views to display a ScrollView with all the Labels. When those Labels are tapped, they are selected and an @State boolean property in the Label-View is toggled. So at the bottom when a "Submit" Button is clicked, the values of the selected Labels are sent to a server.

            In the "Submit" Button I am using a For-Loop to loop over the Label-Views and check for Labels that have myLabel.isSelected == true, but all of them are returning false even after being selected.

            The main View simplified:

            Views are structs in SwiftUI. So passing them into a function will create a copy of those Views. And you are itterating over the original Views that have not been modified.

            I think a ViewModel/Model would be best here.

            Phaser 3 - Particles become more the more often I emit them?
            Asked 2022-Feb-19 at 11:25

            I have particles that I emit when clicking and moving my mouse over a certain object. However I noticed that while the particles start out as little, they become more and more the more often I click and move my mouse,until the stream of particles is far too dense.

            This only seems to happen when I click down multiple times (thus triggering the pointerdown event multiple times), not when I click once and keep moving.

            How can I stop this?

            ANSWER

            Answered 2022-Feb-19 at 11:25

            The problem is, that you are adding a new scene.input.on('pointermove',...) event-handler in the pet function, on each click.

            I would only change the code abit (look below), this should prevent generating too many particles and too many event-handlers (too many event-handlers could harm performance, so be careful, when adding them).

            Here is how I would modify the Code:
            (I stripped out and added some stuff to make the demo, easier to understand and shorter. And also that the snippet can be executed, without errors/warnings)

            Go - How to link Go macOS binary in an Xcode project?
            Asked 2022-Jan-30 at 23:44

            I'm completely new to macOS development, this might sound quite basic.

            I need to distribute a Golang app for macOS. I built the Go executable for macOS, the executable works fine on macOS. I made its .app structure following this tutorial

            But before distributing it, I need to do a few things like code signing & integrating Sparkle (for updates).

            For that, I need to open this .app as a Xcode project. How do I do that ? Xcode recognizes .xcodeproj extension

            You do not need to open the app as an Xcode project - that doesn't make sense as such and cannot be done, as the app is not an Xcode project.

            I would suggest instead using the gon tool you can find here for code signing.

            I’m not clear what the circle effect you were hoping to see was but no, this isn’t at all the correct way, sorry!

            All you really did by changing sparkles to circle the first time was effectively set the number of falling sparkles to zero, which is why they stopped falling.

            There’s not much point changing variable names because they are really just labels. So for instance, if you changed every use of sparkles to circle you’re only really changing a label, not changing what the code does.

            If you’re only just learning JavaScript it’s probably going to be beyond your capabilities trying to change the effect to something specific, but you could try playing with other values and seeing what happens.

            Hope it helps! I think tinkering with other peoples scripts like this is a great way to start to understand coding.

            UPDATE

            The part of the code that animates the sparkles starts from line 140 - try tweaking some of that code.

            For example on line 143, I changed it to stary[i]+=1+Math.random()*1; to make the sparkles drift down more slowly

            The goal is this cool sparkle effect by Josh W Comeau :

            Here I'm creating two elements that represent a star each. All animations are done in SVG animations. The two symbols differ a bit in the timing. The elements refer to the two symbols and I animate the visibility attribute to make the star appear/disappear "randomly". The timing of the visibility is following the timing of the symbols.

            In the example I embed the SVG and I have made a Data URL version of the same SVG and using that as a background on the

            I fell that this is a fairly simple solution, but maybe you can do something similar using CSS animations.

            You can just update the values on the User property of the imported CSV, there is no need to create a $list = @() to save the results.

            Assuming $ImportFile.User contains valid UserPrincipalNames of Azure AD Users, the part you're struggling with would look like this (definitely no need for a function):

            So what happened is that the library in Debian providing support for live555 was removed in February of this year, this affects all downstream distros including but not limited to RPi OS and Ubuntu:

            https://askubuntu.com/a/1363113

            The 2 active versions were 2020.01.19-1 and 2018.11.26-1.1, Live555 has since added GPL license headers to the offending files, however the RFC issue remains.

            Now you may be tempted to just download the latest Live555 source code and compile it... it does not work. There have been changes to function names and structures referenced by VLC, and as such VLC will not compile against the source. You need to get an older version, I specifically used this one, which is a tweaked snapshot from 2020 prior to the modifications that prevent VLC compilation:

            https://github.com/rgaufman/live555

            The configuration you want is ./genMakefiles linux-with-shared-libraries, I do not know if it is required but since my system is x86-64-bit I added -m64 to the compiler options first

            After compilation and install, I went on to compile VLC, adding '--enable-live555' and '--with-live555-tree=extras/live555-master' after placing the root Live555 folder in the VLC extras folder, however VLC failed to compile, it turns out the Live555's make install does not copy all the header files needed to where VLC is looking. They were dropped as 4 subfolders into /usr/local/include/, and the actual libs into /usr/local/lib/. Adding the correct CXX/CPP flags will make it look where they were put, however I put them all in a single folder and used 1 flag.

            I also had to '--disable-mod' to work around a dependency version issue that I had no interest in fixing, since I do not use modplug or any mod files.

            50 minutes later... VLC successfully compiled! However it was expecting the libraries for Live555 to be in /usr/lib/ not /usr/local/lib/, since it took so long to compile I was just fine with linking or copying the libraries into the expected folder, and after that VLC works with RTSP when linked to the new file. Or you can choose to maintain the original VLC and run the new file directly if you need to load the camera feeds.

            We can remove the elements in the resulting dictionary from to_representation() by accessing the show attribute of each item in the notifications.

            Depending on how you want the notifications to show, here are 2 options:

            • Option-1: If you want to remove all notifications if at least 1 show is False
            • Option-2: If you only want to remove the notifications where show is False
