Scratch++ | A text based Programming Language made in Scratch

Scratch++ | Introductory to text based programming

Scratch++ is a custom coded programming language/engine made in Scratch that combines the fundamental aspects of text based programming languages with the syntax of Scratch code blocks. Designed mainly for experienced Scratchers who are planning to advance into text based programming and Scratchers who have already advanced beyond Scratch. Read further to read the instructions on how to write Scratch++, I will try to explain it in as Scratch user friendly as possible.

Thank you so much!

Tiny update here:
As of v1.0.21b update, you are allowed to use “else” command written right after “if” statement. Here's a little example.

if 3 == 4 {
set test to 1
} else {
set test to 2
}

I've also updated the original thread as well.

Thanks! I always wanted the else statement!

I was messing around with the code and I decided to make an easy-to-use angled step system, but it says there is an error on line zero. Maybe this is just a bug on my end, here is the code if you want.
main.scr/ask(“Starting x”)§set x to (answer())§ask(“Starting y”)§set y to (answer())§ask(“distance to travel”)§set targetdist to (answer())§ask(“angle of travel”)§set direction to (answer())§define step(dir,dist){§change x by (cos((dir))*(dist))§change y by (sin((dir))*(dist))§}§define report(x,y,dir,dist)§print “We are at x:”(x)“, y:”(y)“.”§print “We traveled a distance of”(dist)“at an angle of”(dir)“.”§}§step(direction,targetdist)§report(x,y,direction,targetdist)§

What is does is this:

when green flag clicked
ask [Starting x position?] and wait
set [X] to (answer)
ask [Starting y position?] and wait
set [Y] to (answer)
ask [How far do you want to travel?] and wait
set [targetdist] to (answer)
ask [What angle do you want to travel at?] and wait
set [direction] to (answer)

and then functions to step and evaluate the end result.

So… 2 things.
1. I've fixed the ask() function from methods that takes no parameter that now allows you to input a string. For example ask(“How are you?”)
2. You need to assign ask() to to a variable, it's not an independent function.

In your case,

main.scr/set x to ask(“Starting x position?”)§set y to ask(“Starting y position?”)§set targetdist to ask(“how far do you want to travel?”)§set direction to ask(“what angle do you want to travel at?”)§

It's a little bit buggy importing, Scratch doesn't allow some characters.

I mean, from what I can tell. Scratch++ is text only, just like the early days of programing (Like on the Commadore PET). And back then to get anything close to graphics you had to use text characters. I'm not saying add more graphics though, I'm just pointing out the similarities.

some ASCII characters for minimal graphics would be nice though again, not pressuring you.

It's just that I have no knowledge on frontend stuff. Might be a good update once I learned something related.

please don't tell me someone is going to make a coding game, in Scratch++, which is a coding game, in Scratch, which is a coding game too.

Scratch++ doesn't have graphic capabilities, but someone might make a coding engine inside Scratch++ that was able to make computer graphics. That can only mean one thing,

Scratch inside Scratch insi…

I know a lot about it and I can summarize it.
ASCII is the standard text & text rendering scheme for all computers and keyboards, there's 3 categories that are self explanatory.

Printable: These are the characters you see and can generally use
Control: These control how it's rendered but that is unrelated to this
Extended: These are the ones I'm talking about, they aren't generally used but are easily accessible on many older computers.

Here's a table of all of them, no need to add all of them, just the ones that look like graphics (like characters 200-206)

I counted all the ones that look like graphics already, there's 22. And I think to access them it could be a simple tab somewhere that allows it. Like you've might've seen I know what it's like so once again, I'm not pressuring at all. If you need info I'll be happy to give it!

Suggestion: Add String Functions.

A great approach would be to implement methods similar to how strings are in python:

“hello!”.capitalize()

Why not add `.replace()`?

“(A)”.replace(“(A)”, “Hello.”)

This would allow for formatting and easier implementation of text generators.

In other words, this is a fantastic project! Keep going!

Great suggestions, I'm still trying to figure out a way to do it. I might just make it the first 3 parameters methods.

Added upper(“”) and lower(“”), thanks for suggestion!

Is it possible to declare a variable like this: var b = random(1, 255) as an example
