renpy define character
#Simple defining:
define shorthandName = Character("Name", <Optional: Parameters>)
#Call character:
shorthandName "Text goes here"
#######################################
#Character with image Attribute
define shorthandName = Character("Name", image="fileName")
show shorthandName mad
shorthandName "I'm a little upset."
shorthandName happy "But it's just a passing thing."
#without the image in the definition, you'd have to type in
#show shorthandName happy
#Putting an @ in between the image specifier ("happy") between the
#character's shorthand name ("shorthandName @ happy") will make
#that only apply to one line.
