NPC Code:
showmsg index,message,x,y; //Show's a message as if there was an NPC with the message command on x,y;
changemsgsize index,size; //Changes font size
changemsgfont index,font; //Changes message font
changemsgcolor index,r,g,b; //Changes message color
Just a few ideas, it's already scriptable by combining #K with a for loop and some other things but this would be easier.
