RE: the "message received?" block
About a month ago I showed you a picture of code and asked you whether you wanted to achieve something like this (here's the post: Scratch 3 block help). I was hoping you'd notice yourself that this idea cannot possibly work the way you think it would, because the predicate is only evaluated once per loop iteration, and lots of other messages can be broadcast during that time. In order for your idea to work you need to ask at exactly the right time, otherwise you can't be sure.
I'm a little disappointed that you didn't realize this problem in your thinking, even though Joan (in this post here: Scratch 3 block help) and before him Brian (in this brilliant post here: Scratch 3 block help) showed you exactly what the issue was and how to address this, even explaining it all here: https://forum.snap.berkeley.edu/t/scratch-3-blocks/361/39?u=jens. It boils down to needing two scripts for this, one event listener that records the messages, and the predicate that checks the previously recorded message cache.
The fact that you're disappointed with this solution is good! Your disappointment is proof that you know that there should be a better way to control the flow of a program than events. Events are great to initiate scripts but ugly for anything else, as these examples and this discussion shows. What other ways can you think of to control parallel programs?
I am very disappointed now. But I need only a block https://en.scratch-wiki.info/wiki/List_of_Block_Workarounds#Non-Existent_Blocks there are some scratch mods that contains this block. I found this one day but I forgot to book mark it. So that I can't find it. Sorry for inconvenience.
Wait! I gave you an open question: What other ways can you think of to control parallel programs? I'm trying to engage you in a discussion from which you'll learn. So... ?
Thanks for help but I would like to know more about snap!
Thank you for engaging me in a discussion to know about this!
How to do a js script to add Tamil and Hindi to text to speech library?
What is happening to my ideas? Is there any work on this?
Hi,
As you can see in #2387 Tamil was been added to Speech lib (also with all the other "Snap! languages").
Aside from this, I beg you to close this topic (asking for scratch 3 blocks) and open a new one for each question to allow some organization and logic to the conversations.
Thanks,
Joan
As you asked this thread is closed. Don't delete this thread.
Can we use this thread to general doubts of scratch 3 blocks?
If so we need not to create more and more threads instead of one.
So this thread will not contain solution.
If we do change this thread into a general Scratch 3 block thread, we would probably need to split the topic and move the new topic into a new category.
Wouldn't that go in the Scratch forum?
Not if it's talking about moving the blocks to Snap.
Oh. I thought we were done with that topic. If someone needs a particular block, they can start a thread about that block in the Feature Requests category. But if it's just because Scratch has it, that won't be very convincing.
Yknow we could also make a forum topic where people give workarounds to Scratch 3 blocks.
Sure, knock yourself out.
Or use a join block "-" + (n)
Where would I put the topic though? On Scratch, you'd put it in the suggestions category so people suggesting Scratch 3 blocks would see it, but I don't know about here.
I think this is the 99th post
