how to make Appearing letters?
Hey i'm making a game and I need something. After you step on a certain brick a little message will appear saying: Hello and welcome to the world! I don't want to it to just appear though, I want it to appear letter by letter if that makes sense.
Like for example the letters will show up like this only it wont appear in rows it will happen all in 1 row. I don't want to have to add a letter every time so if you know an easy way to do this please tell me! W We Wel Welc Welco etc. i want it efficient though
message.Text=W message.Text=We message.Text=wel message.Text=welc message.Text=welco message.Text=welcom message.Text=welcome

Let's say we have a finished string message. If we want to build the version of it growing one letter at a time, there's essentially two approaches that are very similar:
- Grow the text by the
ith character - Use the substring of the first
icharacters
They look like this:
Growing:
text = ""
for i = 1, #message do
text = text .. message:sub(i,i)
print(text)
end
Substring:
for i = 1, #message do
text = message:sub(1,i)
print(text)
end
I find the second approach to be much more elegant.
