How to get a blocks check type

[OrrinOliver]

Is there a way to get a blocks check type while using var blocks = workspacePlayground.getTopBlocks(false);

I'm trying to find if a block has the custom check type of "Board"

Hello!

Firstly let me clarify that check types are associated with individual connections, not with blocks. For example you could have one connection with a check of ['String'] and another connection with a check if ['Number'].

So to get the check of a connection you can do:

```

var block = /* get access to a block */

var check = block.getInput('MY_INPUT_NAME').connection.getCheck();

```

or the following for the non-input connections:

```

var check = block.outputConnection.getCheck();

var check = block.previousConnection.getCheck();
var check = block.nextConnection.getCheck();

```

Note that getCheck returns an *array of strings* not just a string.

I hope that helps! If you have any further questions please reply =)

Also, can I ask what this functionality is for? Sounds like part of an interesting problem!

Best wishes, I hope you have a lovely week!
