UFE2 is very nice to be able to set up the details for a fistfight, but I felt it was less flexible than that for setting up the projectile.
Sorry to duplicate what I asked in my own question thread, but let me order all the requests.

・Projectiles that follow synchronously with the main body
Like the VT of SF5 Menat
・Projectiles change with branching conditions.
Bouncing trajectory when hitting the floor or wall
・Change in command input of Projectiles
It is like the dolphin ring that Mei has in Guilty Gear, or Zato's alter ego.
・Management and branching by gauges
・Self-destructive bullets that also hit themselves
Faust's head throw Attack in Guilty Gear, for example.
・Can pick up items that have fallen.
(If there is a self-destruct setting, I think that could be implemented with that, in which case this may not be necessary)
