Info and Updates
I've put together several options for round shadows that mimic Street Fighter 3's round shadows. These were all designed to be simple copy paste use, for perfect conversion you would probably want to reference a sprite table and not a universal math formula since some of the characters in SF3 don't stick to the same rules as others.
*IKEMEN users,
This version is still compatible with any version of IKEMEN since it uses classic mugen triggers and sctrls but Foobs has put together a really great version just for IKEMEN that you should checkout. (Only compatible with the nightly build as of April 1st, 2024)
https://github.com/RealFoobs/SF3-like-Shadows
* Two other versions that use M.U.G.E.N's actual shadow mechanics will be posted here soon.
Download SF3 Shadows sprites. I have each one set as their own animation starting at 8530 with time set to -1 for each in the air file. Pick the version you like and paste it in you characters. This code now uses explods so you can use fightfx.air now!
This goes in the characters Air file
*If you don't have a blank animation already
; Blank
[Begin Action 9741]
-1,0, 0,0, -1
This goes in [statedef -2] for players and in helpers for projectiles
*for projectiles, AssertSpecial noshadow will need to be in every state the projectile uses.

Version 1 | Scale based round shadows
[Not how it’s actually done in sf3, this has smoother size transitions and only uses one sprite(8.png in the shadows download). There are some options in the 'scale' parameter of angledraw. You can use it as default and the shadow's size will be calculated based on the width in the character's constant or you can adjust your base shadow size manually. ]
