This is what I've gotten to, but I want to know how to make it move on to the rest of the text when spacebar is pressed.
This is what I used to get this effect:
var/dmifont/TahomaBold11pt/myFont = new
obj/Textbox
icon = 'Textbox.PNG'
screen_loc = "2,1"
layer = FLY_LAYER
proc/WriteText(txt)
var/icon/I = myFont.DrawText(txt, 15,10, width = 516, maxlines = 5,\
flags = DF_WRAP_ELLIPSIS)
src.overlays += I
mob/Login()
var/obj/Textbox/T = new
T.WriteText("Professor Carpe: Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in \
a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard \
McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the \
more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites \
of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from \
sections 1.10.32 and 1.10.33 of de Finibus Bonorum et Malorum (The Extremes of Good and Evil) \
by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during \
the Renaissance. The first line of Lorem Ipsum, Lorem ipsum dolor sit amet.., comes from a line in section 1.10.32.")
