Was wondering how I can edit Ness’s PK Fire to travel further distance (both ground and air), and where this data can be found?
Also, cant find the hitbox data for stuff like Peach’s Side-B hit, Link’s bomb + boomerang hitbox data, other projectiles.
HSDraw can view all of that data, except if won't label information such as the PK Fire spark's duration or its travel speed. Projectiles and certain held items are stored in "Article" folders which contain their models, their animations if there are any, and their commands (e.g. hitboxes.) Ness's PK Fire is of course also an article, however, its attributes are displayed as floating-point hexadecimal for which you need a converter to properly edit.
To avoid the conversion hassle, you can edit PK Fire's duration or its speed in the much more user-friendly CrazyHand v1.31 instead. They're two of Ness's character-specific attributes which you can access via the tab in the top right corner.
As for Link's projectiles, they're also articles which you can view in HSDraw. CrazyHand can also view them to some extent, but it's very limited. Peach's Side-B should be listed by its usual community-given name in CrazyHand's "Subactions (Attacks only)" tab or as "SpecialS" or "SpecialAirS" everywhere else.
