Go to the pinned post above this called, "[How do I] Frequently Asked Questions" go to the RPG category on the list, there are 4 links in there you might want to check out named,
- "Visual Novel/Dialogues example"
- "A dialog system with answers"
- "Even more dialog systems"
- "Ingame dialog popup example"
I'd post links, but my rep isn't high enough yet.
However, Sisyphus is right, you should definitely read the manual. You'd be surprised at how many questions can be answered by a simple search through the manual.
Also, bookmark the FAQ. Anything that isn't in the manual is in there and anything that isn't there is around the forums, just gotta look.
