Understanding the Need for SOCD Cleaning in Fighting Games

It is crucial to prevent unfair gameplay situations. SOCD cleaning refers to handling the simultaneous input of opposite directions. This wasn’t as much of an issue in the past because traditional Arcade Joysticks or directional pads made it physically impossible to input opposite directions simultaneously.

However, with the popularity of gaming peripherals like Fight Sticks from brands such as HitBox Arcade, Mixbox, or Junk Food Custom Arcades, players have increasingly started incorporating SOCD to perform impressive and powerful moves.

Impact of SOCD on Gameplay in Fighting Games

SOCD significantly influences fighting games, especially in competitive play. Players with advanced controllers like the HitBox can perform complex moves more easily than traditional controllers, leading to a higher skill ceiling.

This capability also brings challenges. In some cases, like in “Marvel vs. Capcom 3,” SOCD has led to unintended game mechanics that potentially unbalanced gameplay. Game developers and tournament organizers have implemented SOCD cleaning rules to address this.

These rules are essential for maintaining fairness, ensuring no player has an undue advantage due to their controller type.

SOCD Resolution Basics

1) Use both directions (recognized as a diagonal direction): The first way is to use both directions, which means that the system will recognize the input as a diagonal direction.

2) Choose neither direction (ignore the input altogether): The second way is to choose neither direction, which means the system will ignore the input completely.

Neutral Resolution: When both left and right or up and down are pressed, the system resolves this input by cleaning it to neutral, ignoring it altogether.

3) Select only one of the directions (prioritize one input and ignore the other): The third way is to select only one, meaning the system will prioritize and ignore the other.

Absolute Priority Resolution: When both are pressed, the system prioritizes one direction.
Last Priority Resolution: Similar in that it prioritizes one direction over the other, but the criteria for selection might differ.
Last Input Controlled Priority: Prioritizes the most recent input over the conflicting input.
First-Input Priority Resolution: Prioritizes the first inputted direction.
First-Input Controlled Priority: Similar to the above, prioritizing the first input.

The Natural or No Resolution method doesn’t fit into any of these three basic types as it implies an absence of any SOCD cleaning or specific resolution handling by the system.

SOCD Resolutions are crucial for ensuring fair gameplay, as they prevent players from gaining an unfair advantage by inputting multiple commands simultaneously. Game developers and controller manufacturers must consider SOCD Resolution when designing their products to ensure a level playing field for all players.

SOCD Resolutions Overview

Specific Resolution	Basic Type	Details
Neutral Resolution	Choose neither direction (ignore the input altogether)	Ignores both inputs when opposite directions are pressed (e.g., left and right or up and down).
Natural or No Resolution	Does not fit any basic type (implies absence of SOCD cleaning)	Lack of SOCD cleaning may allow for unpredictable or unfair gameplay.
Absolute Priority Resolution	Select only one of the directions (prioritize one input and ignore the other)	Prioritizes one of the conflicting directions over the other.
Last Priority Resolution	Select only one of the directions (prioritize one input and ignore the other)	Prioritizes one direction, but criteria for selection may differ from Absolute Priority.
Last Input Controlled Priority	Select only one of the directions (prioritize one input and ignore the other)	Gives priority to the direction of the most recent input.
First-Input Priority Resolution	Select only one of the directions (prioritize one input and ignore the other)	Gives priority to the direction of the first input.
First-Input Controlled Priority	Select only one of the directions (prioritize one input and ignore the other)	Similar to First-Input Priority but may have specific implementation differences.

SOCD Cleaning, Resolutions, and Focus

SOCD (Simultaneous Opposite Cardinal Direction) occurs when a game or controller detects opposing directional inputs simultaneously. The system must resolve these conflicting inputs with a specific solution or resolution.

Neutral Resolution: Common in most controllers and games, the impartial resolution ignores both inputs when opposite directions are pressed, ensuring fair gameplay by avoiding unfair advantage.
Natural or No Resolution: Less common in modern gaming, this method was inherent in older arcade joysticks where physically inputting opposite directions was impossible. Today’s advanced controllers, like HitBox Arcade or Mixbox, necessitate formal SOCD resolutions to maintain gameplay balance.
Absolute Priority Resolution: This resolution prioritizes one direction over the other, ensuring no player gains an unfair advantage with simultaneous opposing inputs.
Last Priority Resolution: Similar to absolute priority, this method selects one of the conflicting directions, maintaining game fairness.
Last Input Controlled Priority: Here, the system favors the most recent input, a vital measure to prevent the exploitation of simultaneous inputs.
First-Input Priority Resolution: Opposite to the last input priority, this resolution precedes the first inputted direction, promoting balanced gameplay.
