Text functions in block coding don't appear to be working
I am trying to do some work with text strings in the block programming - (I am trying to create a text array of players) and the function to split the string does not appear to work. See https://makecode.com/_hCtAJgJqMdr1
I have a string with player names separated by comma and the split function is unable to find the separator and split the text - I am hoping the function is supposed to return the 1st half and modify the search string to leave the remainder - but it doesn't seem to do anything.
I noticed there is no documentation for the split function at https://minecraft.makecode.com/reference/text
and that when switching to python it doesn't recognise the functions, javascript does - but still doesn't work!

Any comment on whether this is a bug? Some of the text functions don't appear to work and have zero documentation. How do I submit a bug report?

I think the split command takes string elements and converts them to elements in an array.
(works with commas, too!)

That's a good question! You want to go to here:

That is great! Works better than I assumed. Thank you.
Whoever is in charge of the documentation should put this in since there is no documentation for this function.

Hi, unfortunately - your code works - but when I try and use it for an array of player names - it doesn't....... can you see where I am going wrong? As you can see I can get a list of the 2 players in the game with a comma, but the split function doesn't seem to find that comma. Is it a special comma?

Aside from the comma question, you may have a different issue. I think players may be a special object in Minecraft, not just a string name.
I'm not sure. try running this to see what I mean:
them = world._all_players
say (them)0 -
Not sure what you mean. I tried converting to Python and the code switches back and forth. But the Python version doesn't seem to work in same way.
I used the "to string" function to turn the list into a proper string - and that seemed to work.
Am I going about this the wrong way though. Is there an easy way to create an array of current player names I haven't thought of?

Just all a bit strange. I think the text functions may be a bit buggy. They aren't fully documented and I guess they are not used that much - hence it has slipped under the radar. I did some more experiments and the join function is happy with that string - but the other functions just don't like it.

I think references to players and entities are not usual array elements:
It creates a string of the entities, but splitting a list of string form "Target Selectors" seems to be the problem.

Hi Tim Longman,
Thanks for reporting the issue with split not working correctly after converting from Blocks to Python. Our team has been able to verify the problem and I'm passing the feedback on to the MakeCode team.
Deborah got it exactly right - what you are seeing in your examples is that the purple block returns a "TargetSelector" type and not a simple array. Array and string manipulation functions may not work as you'd expect on the TargetSelector objects as they are designed to be used with other purple blocks. That said, many of the blocks do let you use them with other types of blocks, so trial and error and experimentation are the best ways to learn.
What is the final result you are trying to achieve? If we knew your goal we may be able to offer a few suggestions to help you get there.Thanks!

Thanks, Micah! I think Tim Longman sounds like he has something interesting up his sleeve, so I hope we can determine that workaround out.
Tim, you have intrigued me. What were you going to do with that array of players?

Thanks guys,
In your example you didn't use the "to string" function to turn the selector into a string. The substring, split, and find text functions don't work - but "join" does quite happily.
What I am trying to do is find a way to keep scores for players in a 2d array and also be able to give specific players items, or xp or whatever.
The selector only allows for random players or for yourself.
First task is to simply get all the active player names!

I like where you are going. I think the 2-d array with string versions of player names and an integer for XP amounts will be attainable. What I think will be trickier will be getting a usable player target selector to allow you to address a player when you want to give them something.
In the world._all_players (post above) you see the results of the target version. I wish you great success with parsing these selectors out. I was able to do some things with the target selectors, but not get a *working target selector variable *into an array.
I'd love it if you would share your code (above) with me, if you are willing. It is a great idea. I would enjoy also trying to make it work somehow. But in any event, let me know how it goes. I have wanted to do things like this with NPCs and such, myself. =]

I haven't got very far! Fell at this hurdle! How do you test the world._all_players method? I haven't strayed far off block programming so far.
My makecode ref is _2g6M9hUhaUCc but there isn't much code there.
