Need help making code more efficient

[dhbergen]

finished getting the code to work. adjusted for the fact that having another def... in my code causes problems.
solution here:

character = 0
cur_str = []
my_string = "this is a test."
def setup():
    size(400, 400)
    
def draw():
    global character
    global cur_str
    global my_string
    frameRate(15)#again, added for exaggerated effect
    if character < len(my_string):
        cur_str.append(my_string[character])
        text(''.join(map(str, cur_str)), 10, 30)
        character = character + 1

for those wishing to keep the text on screen after the sentence has typed, add:

else:
        textSize(32)
        text(''.join(map(str, cur_str)), 10, 30)

to the end of the code
