Unity 2D animated tiles library: IsSelected variable not working or not present within RuleTileEditor.cs

I have just tried downloading a library which will allow me to add animated tiles to unity. I have been following this tutorial:http://shadowpeakstudios.com/2018/10/22/unity-tutorial-animated-tiles/

It told me to download this library in order to work the animated tiles: https://github.com/Unity-Technologies/2d-extras

After this the tutorial told me to unzip the library and place it into my assets folder. It loaded into my assets folder and then got the following error:

Assetsd-extras-masterd-extras-master\Editor\Tiles\RuleTile\RuleTileEditor.cs(277,26): error  CS1061: 'ReorderableList' does not contain a definition for 'IsSelected' and no accessible extension  method 'IsSelected' accepting a first argument of type 'ReorderableList' could be found (are you  missing a using directive or an assembly reference?) 

Does anyone perhaps know why this error is occuring.

Disabling Media Library and Bypassing it

Actually I am facing an issue and I am new to WordPress. I want to disable the Media Library for non_admin Users. I want that the Users on my site can upload images without having to upload it through WordPress window. I simply don’t want "Upload featured image" Window to show up every time a user wants to upload an image. I researched this topic a lot but couldn’t find a correct answer. enter image description here

How to prevent WordPress Media Library from removing image?

I have a custom post type that must have its feature image. Its feature image also appears in the Media Library where user can delete the image/attachment file permanently. But I want to prevent user from deleting the feature image of my custom post type. So I use the following hook to intercept the ajax request, validate if user is deleting the image of my custom post type and stop the process by using wp_die().

add_filter('pre_delete_attachment', 'check_my_custom_post_type', 0, 2); function check_my_custom_post_type($  delete, $  post) {     if (Yes it is image of my custom type) {         wp_die('My message', 'My title', ['response' => 400]);     } } 

It works fine on the server side. The image of my custom post type cannot be deleted. But Media Library, on the client side, still removes the image from its views even the image on the server side has not been deleted and an exception 400 has been thrown.

To all html & css lovers. We made this UI Library for you :)

We announced Frontendor.com HTML blocks & templates library last days after we focused on three essentials gaols:

✦ Neat code, easy to customize
✦ Separate blocks, easy to integrate
✦ Create landing pages by COPY-PASTE.

This way, we can build a new landing page every time just by copying the HTML & CSS from our library.

We would love to hear your very honest feedback and suggestion. Thank you.

What is the possible character set for the jsonwebtoken nodejs library?

I see a lot of folks using the following for a private key when using the jsonwebtoken library:

const hexStr = require('crypto').randomBytes(64).toString('hex') 

But this returns a character set of only 0-9 and a-f. Not a good practice it seems.

jwt.sign({ name: kennedy }, hexStr); 

However this approach is seeming a much better, more secure approach as now we’re using the full character set as binary data:

jwt.sign({ name: kennedy }, Buffer.from(hexStr, 'hex').toString()) 

Thoughts on this? Is the second approach a better one? I’m just looking for affirmation (or not!) that I’m doing it correctly.

Independent C library or function (on Linux) to programmatically generate a self-signed certificate [closed]

Is there a simple C library or function to programmatically generate a self-signed certificate in C on Ubuntu? Of course, one can execute a simple system("....") call to execute a CLI. I am looking for a native, small, stand-alone library just for this purpose with possibly added functionality but not with the full-weight of TLS implementations such as openssl, boringssl, mbedTls, etc.

Merge Multisites with Shared Network Media Library

So have a multisite setup which no longer needs to be a multisite but I’m left with a bit of a mess since I used Network Media Library plugin to host images for all sites on the network. I’ll try to break it down:

  • started out with WP multisite
  • created two sites on the network
  • installed Network Media Library
  • site #1 hosted the media library
  • both sites hosted posts
  • (about a year and a lot of posting goes by)
  • pulled site #1 out of multisite to be hosted independently
  • left with multisite running site #2 but still pulling it’s media from site #1

What I want to do now is combine site #2 which contains all my posts with site #1 which contains only media. My concerns are:

  • if I merge tables there will be ID conflicts (some posts will have same ID as attachments)
  • if I use import function to bring images into posts site then images will be given new IDs and post thumbnail relations will all break
  • if I use import function to bring posts into images site then post IDs would change which can’t happen because we use the ID in the post URL

The best idea I have so far is to somehow…

  • use the WordPress import function to import all the attachments into the posts site
  • log old and new IDs into a new table in the DB as the process works
  • then iterate over all the posts switching old for new IDs in the post_meta _thumbnail_id fields
  • ideally then be left with one site which contains all the posts and attachments so I can reduce the install down to regular non-multisite.

There’s tens of thousands of posts on these combined sites so performing these functions is no small feat and really not sure where to start so I wonder if anyone has any experience of a process like this or ideas for alternative solutions.

Thanks for reading.

How to show demo wordpress websites like themeforest or elementor library?

Suppose I’ve 10+ WordPress themes to sell, Now I want the user to click on the theme image to open a preview of the theme just like ThemeForest or elementor library. Should I create 10+ directories and install WordPress for each theme?

Please checkout elementor templates library https://library.elementor.com/ for a better idea

Thanks a lot for your response.
