White Ties? I dunno. Either a game, or an artist.
Knight Blade is a demo game that came with the Japanese version of XP.
It can be downloaded on the Enterbrain website.
HK = Half Kaiser (a character sprite based on the template created by ShowKaiser)
Autorun & Parallel will both start executing automatically when they come into scope. (when you enter the map)
Autorun will execute explicitly until finished, preventing any other code from executing until it's done. (character can't move)
Parallel will execute, but allow the other classes update methods to continue running. (character can move, other events can process...)
Autorun is pretty much used for cutscenes, or initializing something (variable, picture, etc..) at the beginning of a map scene,
and should almost always be terminated by setting a self-switch, and using that self-switch as the condition for another event page.
Parallel is commonly used to 'track' something (timer, player position, event positions, etc...), or to execute something in tandem to the game action (NPC movement, random events, time related events like day/night, etc..)
Hope that helps
