Skill Prediction

Simulates skills client-side, eliminating ping-based delays and animation lock.

Note: If your skills become delayed, make sure Windows Defender is disabled. See settings.js for additional configuration options for non-standard setups.

Noctenium Infusion: Having regular, Friendly, or Alliance Noctenium Infusion in your inventory will cause the server to send a huge chunk of redundant data after every skill while using any type of Noctenium Infusion. You may use this mod to reduce the client lag, however the network lag will still be noticable unless you have 50Mbps or higher download speed.

The recommended solution is to delete or bank any Noctenium Infusion and use Refined Noctenium Infusion instead.

config/skills.js

This file contains skill data specific to skill-prediction. The basic structure is as follows:

• classId -> skillGroup -> skillSub -> skillData OR
• classId -> skillGroup -> '*' -> skillData OR
• classId -> '*' -> skillData

skillGroup and skillSub are derived from the skill ID for player skills, which follows a pattern for every skill BHS has implemented thus far:

• XXYYZZ where X = skillGroup, Y = skillLevel, Z = skillSub

skillData is an object containing one or more of the following properties, or a truthy value such as true to inherit defaults:

• type: Special skill type, one of the following:
• • 'retaliate': Retaliate skill that can be used while knocked down.
• • 'hold': Temporarily-held skills (Corruption Ring).
• • 'holdInfinite': Infinitely-held skills (Stand Fast, Axe Block, etc.).
• • 'dash': Fixed-speed dash using S_INSTANT_DASH.
• • 'teleport': Fixed-distance teleport using S_INSTANT_MOVE.
• • 'lockon'
• • 'lockonCast'
• • 'charging': Charging skills (Thunderstrike, Radiant Arrow, etc.).
• • 'storeCharge': Store charge level for the interrupted skill, to be granted later using grantCharge (used for ex. Evasive Smash).
• • 'grantCharge': Grant the charging level as a charged skill.
• • 'userProjectile': Client-sided projectile (not a skill).
• fixedSpeed: Fixed animation speed (always 1 or unset).
• length: The skill animation length before taking into account speed multipliers.
• distance: The distance the skill moves the player in the direction it's facing.
• noInterrupt (array): A list of skills that cannot be interrupted by this skill. Each entry can be either skillGroup or 'skillGroup-skillSub'.
• projectiles: An array of skillSub projectiles. Requires DEBUG_PROJECTILES to be enabled.
• triggerAbnormal (object): Abnormalities this skill triggers on use. Keys are abnormality IDs, values are durations.
• consumeAbnormal: An array of abnormalities consumed before this skill begins.
• consumeAbnormalEnd: An array of abnormalities consumed after this skill ends.
• movement: An array of segment objects containing the following parameters (from S_ACTION_STAGE):
• • duration: Segment duration.
• • speed: Animation speed multiplier for this segment.
• • unk: Always 1?
• • distance: Distance moved for this segment.
• glyphs (object): Keys are glyph IDs, values contain one or more properties:
• • speed: Animation speed multiplier.
• • chargeSpeed: Bonus charging speed (additive).
• • movement: Overrides movement.
• • distance: Multiplies distance.
• • stamina: Added to stamina.
• abnormals (object): Keys are abnormality IDs, values contain one or more properties:
• • speed: Multiplies speed.
• • chargeSpeed: Bonus charging speed (additive).
• • chain: Overrides skillSub (last abnormal defined takes priority).
• • skill: Overrides skillId (last abnormal defined takes priority).
• chains (object): Keys are skillGroup or 'skillGroup-skillSub', values override skillSub.
• inPlace (object): Used while casting a skill without pressing movement keys.
• • movement: Overrides movement.
• • distance: Overrides distance.
• stamina: How much Stamina (Resolve, Willpower, Chi, Ragnarok) is required to use this skill.
• instantStamina: Simulate stamina usage without waiting for server response.
• requiredBuff: Abnormality ID (or an array of possible IDs) required to use this skill.
• forceClip: Rubberbands the player to the server location in S_ACTION_STAGE.movement (if set) when the skill ends. Used to prevent iframes from clipping through gates, etc.
• interruptibleWithAbnormal (object): Keys are abnormality IDs, values are a skillGroup that can be interrupted with this skill.
• chainOnRelease: skillSub animation to play if the button is released early (only for type: 'hold' or type: 'holdInfinite').
• teleportStage: Stage at which to apply teleport (only for type: 'teleport').
• partyOnly: Lockon only applies to party members (only for type: 'lockon').
• flyingSpeed: Projectile speed (only for type: 'userProjectile').
• flyingDistance: Projectile curve endpoint (only for type: 'userProjectile').
• noRetry: Disables automatic retries for this skill.
• race (object): Keys are race+gender ID, values override skillData properties.
• level (object): Keys are skill level - 1 (to enable array usage), values override skillData properties.
