This provides a helper block for getting the max of a list (given some mapping function): 0_1582317408775_max-using-fn.zip

I think you may have already figured this out (since you reached out via email :) ) but I figured I would post some links in case they can be helpful (to you and others with similar questions)!

There should be some resources available at https://netsblox.org/cybersecurity. (Detailed instructions about setting up the robot are linked to from that page.)

If you have any remaining questions, don't hesitate to post here or send us an email!

It might be worth checking out the NetsBlox Player - it lets you access and play your games on iPhone. Are you hoping for something on desktop/laptops?

Unfortunately, we don't support importing Scratch projects into NetsBlox. However, projects created in Snap! (v4.x) should be able to be imported directly into NetsBlox without issue.

That said, I have seen some other projects, such as Snapin8r2 which might be able to convert the Scratch project into a Snap! project. If it is able to convert the Scratch project into a Snap! project (without any of the OOP blocks), we should be able to import it into NetsBlox!

Hello diamondblock123456,

Can you double-check that the second role has code to have the sprite say hi when it receives a message? I suspect the issue is that roles do not share code, sprites, costumes, etc. If you are familiar with Snap! and/or Scratch, a role is like an independent project in either of those languages.

In other words, it sounds like the first role contains all the code but the second role is an empty project (so the sprite won't say hi when it receives a message).

The easiest way to fix this problem would be to add a message handler in the second role which has the sprite say hi upon receiving the message. (You could also use the "Duplicate" option from the room tab when creating the role which will create the role from a copy of the first role.)

Hopefully this helps!

Communication between different applications (either NetsBlox projects or roles) is possible by sending messages over the network (using the blocks under the "Network" tab in the palette). These messages could be used for many different things in a project such as sending chat messages in a chat application or notifying other players of game events (scoring points, player movement, etc).

Rooms in NetsBlox can help with messaging by detecting if other clients ("roles") are online and to facilitate debugging by recording messages sent over the network. The roles in a room are also used to populate the dropdown in the "send msg __ to __" block.

What type of communication are you thinking about? Does this help answer your question?

Here are a couple basic blocks for printing text to the screen!

[0_1563630859187_sha256.zip](Uploading 0%) Sounds like a cool project! Java code cannot be used directly in NetsBlox but JavaScript can (using the "Javascript function" block under the "Operators" tab). This could be used to either implement sha-256 in JS yourself or to load a JS library providing this functionality.

I have attached an example which uses the implementation provided at https://geraintluff.github.io/sha256/ to provide a custom block for computing the SHA-256 hash. sha256.xml

Would you mind posting it here? I would be happy to take a look at it and see if I can figure something out!

Hello,

Sorry for the trouble. If you could email me the usernames and project names of the students with missing work, I would be happy to look into it! My email is brian.broll@gmail.com.

We also make frequent backups so even if there was a bug in the system (although I don't know of any current saving issues), we would be happy to retrieve the latest backup of the student's project.

Brian
