is the print thing helpfull? Like does it do some thing? example: print("Hello")

It creates a message to the output and the developer console, which you can read from either of those. The developer console is accessed with F9.

E.G. if you do

print("Hello world!") -- this is the code that you always see when you create a script

you will get in the developer console what is shown in the following link:

This is helpful for when you need to debug a script that's not working properly and need help pointing yourself in the right direction.

don't you dare not accept this if it's helpful

The print function is extremely helpful. It's like your flashlight in a dark room. Without it you'll bump into things, stub your toes, walk into a wall, etc...

In short, programming is painful without a print. You can do things like

print("Script ran through here. All good.")
print("Script ran through here. Not good.")
print("What is this? " .. part)

for _,child in pairs(object:GetChildren()) do
    print("What is child? " .. child)
end

It's basically like the things that see if one function goes about and is able to do it's thing. For example:

if workspace.Baseplate then
print'there is a baseplate'
end

That kind of thing, it's easy once you understand it :)

Anyways, hmu on Roblox if you want to learn code, my ign is trycode.
