Displaying text letter by letter
- by Evi
I am planing to Write a Text adventure and I don't know how to make the text draw letter by letter in any other way than changing the variable from
h to he to hel to hell to hello
That would be a terrible amount of work since there are tons of dialogue.
Here is the source code so far
