Decided to write about this since there is no good documentation about these settings.
Digital
“No preference” defaults to Share.
- Share: Inputs are combined together using bitwise OR. Example: The first player jumps while the second player attacks within the same frame will result in a jump attack.
- Grapple: Inputs are combined together using bitwise XOR. Example: Two players pressing jump within the same frame will cancel each other out (no jump will be performed).
- Vote: Requires an absolute majority for the input to register. Example: Two out of three players jump within a frame, the jump will be performed, while two out of four players jump within a frame, the jump will NOT be performed.
Analog
“No preference” defaults to Max.
- Max: The player with the biggest analog motion has his input registered, while inputs from other players are ignored.
- Average: Analog motions are added together from all players and then divided by the number of players, this value is then registered as the input.
