I found it best to search the forums for ".xpp" or".xpf" or "brickftp" and look for project examples people have posted.
My two favorite scripts are Family Feud and OnSetText.
Family Feud triggers a scene director based on a key press. Very helpful for a lot of projects. OnSetText basically does the same thing, but when text is entered into a text box (or via User Input Controls) Also very helpful
