i need some ideas for some custom blocks to add to snapexLib.
you dont have to make the block i just need some ideas.
This is sarcasm, right?
cool blocks!
i found something weird here: it give me an error...
the bug occurs when the say block tries to run
No...
You could write blocks sharing a common theme.
A yet undeveloped theme in Snap! would be: "sets". A set is like a list, but the order of its elements doesn't matter; neither do repeats of the same element. So e.g. {1; 2} = {2; 1} = {1; 2; 2}. Like with a list, anything can be an element of a set, such as characters, strings, numbers, lists, functions, other sets ...: e.g.: {"a"; "word"; -56.45; (1, 2, "many"); IF () THEN () ELSE; {1; 2}}. There is exactly one empty set: {}.
For inspiration on which blocks to create you may want to look to other programming languages or, even better: Set (abstract data type) - Wikipedia.
If I were you, I would implement a set as a Snap! list, at least to start with.
A general tip: start by defining what the block should do, make a comment of it within the definition, e.g.:
Have fun!
If you delete everything from the list, how do you get anything from the list?
I think the map needs to be replaced with keep
You're right. I just made the script on my phone, and I wasn't really paying attention to the blocks.
What's the point of deleting and replacing the elements? So that you can use IS IDENTICAL TO on the result? I would just REPORT (KEEP ...)
I would report as well, but I am modifying a block from their library. The reason I'm deleting all, then adding the items back is to preserve the watcher.
- That only works if
listis a variable, and - That sets it to a new list.
yes?it still removes all instances from that list
No, keep creates a new list; it does not modify the first list.
(What does yes?it mean?)
yes but it sets the original variable not the local one
You've really gotten into metaprogramming! It seems to be your first-choice solution to all problems.
