Deadeye Instinct
Your aim does not move alone.
It follows instinct, pressure, and the weak point hiding under the monster's skin.
Deadeye Instinct is a configurable aim assist overhaul for SULFUR.
It expands the game's original controller aim assist into a stronger and more flexible system for both mouse and controller. It includes three assist styles: Magnet, Natural, and HardLock.
Features
- Mouse aim assist support
- Controller aim assist support
- Three assist styles:
- Optional weakspot targeting
- Smooth target tracking
- Low / Medium / High / Custom presets for Magnet and Natural
- 360-degree HardLock target scanning
- HardLock target priority scoring
- Optional AutoFire
- Runtime weakspot debug overlay
- Edge softening to reduce snap-back jitter
- Controller escape handling for Magnet mode
- Configurable hold key to temporarily disable the aimbot
Assist Modes
Magnet
Magnet is the stronger normal assist mode.
It behaves like a magnetic pull toward the target area. When weakspot targeting is enabled, it tries to pull toward the best available weakspot instead of the enemy's center.
This mode is recommended if you want a strong but still aim-assist-like effect.
Natural
Natural is the smoother assist mode.
It is designed to feel more like aim friction or sticky aim rather than direct snapping. It helps stabilize aim near targets, reduces overshooting, and keeps player input feeling more natural.
This mode is recommended if you want aim assist without an obvious lock-on feeling.
HardLock
HardLock is the experimental strong lock mode.
It scans hostile NPCs around the player, chooses a target using priority scoring, and directly rotates the camera toward the selected target point. It is designed for extreme assist behavior, not subtle assist.
HardLock can optionally use AutoFire.
Preset System
Magnet and Natural use a simplified preset system.
[Assist Mode]
Mode = Magnet
[Preset]
MagnetPreset = High
NaturalPreset = Medium
Available preset values:
Low
Medium
High
Custom
Rules:
Mode = Magnet uses MagnetPresetMode = Natural uses NaturalPresetLow, Medium, and High use built-in runtime valuesCustom uses the advanced config values
Default setup:
MagnetPreset = High
NaturalPreset = Medium
HardLock Recommended Config
[Assist Mode]
Mode = HardLock
[Master Switch]
EnableAimbot = true
HoldDisableKey = LeftAlt
[HardLock]
HardLockMaxDistance = 90
HardLockMaxDistanceCap = 90
HardLockRequireVisibleTarget = true
HardLockRequireLineOfSight = true
HardLockPreferWeakspot = true
HardLockWeakspotBias = 1
[HardLock Target Priority]
HardLockTargetPriority = ThreatWeighted
DistanceWeight = 0.75
LowHealthWeight = 0.25
WeakspotWeight = 0.15
StickyTargetBonus = 0.20
HardLockMaxDistanceCap is a safety cap. The actual search distance is:
min(HardLockMaxDistance, HardLockMaxDistanceCap)
Set HardLockMaxDistanceCap = 0 only if you intentionally want to disable the safety cap.
AutoFire
AutoFire is optional and disabled by default in normal release usage.
[Auto Fire]
EnableAutoFire = false
AutoFireOnlyInHardLock = true
AutoFireRequireAligned = true
AutoFireMaxAngleDegrees = 1.0
AutoFirePulseSeconds = 0.04
AutoFireReleaseSeconds = 0.04
AutoFireRespectSemiAuto = true
AutoFire does not directly call:
Weapon.Shoot()
Weapon.AttemptShoot()
Weapon.DispatchProjectile()
Instead, it controls the original trigger state through the game's normal weapon pipeline. This allows the original weapon logic to handle ammo, cooldown, reload, semi-auto behavior, full-auto behavior, animations, sound, and durability.
Weakspot Targeting
Magnet and HardLock can prioritize enemy weakspots.
The weakspot system uses the game's actual hitbox data:
HitmeshHitmesh.DataHitmesh.Data.GetShapeMultiplier()HitboxColliders- runtime hitmesh / vertex data
Known base hitbox multiplier order found during development:
Eye = 1.5
Head = 1.0
Thorax = 0.75
Body = 0.5
Groin = 0.5
Arm = 0.25
Leg = 0.25
Block = 0
Important limitation:
This system currently uses the base hitbox multiplier. It does not fully evaluate final damage after weapon-specific states, buffs, elemental effects, or projectile context.
Weakspot Debug Overlay
[Weakspot Debug Overlay]
EnableWeakspotDebugOverlay = true
WeakspotDebugOnlyTrackedTarget = true
WeakspotDebugShowAllPositiveShapes = false
The overlay displays the weakspot polygons used by the game's runtime hitbox data.
Default color meaning:
Red = very high multiplier
Orange = high multiplier
Yellow = medium multiplier
White = lower positive multiplier
This is mainly for testing and tuning.
Installation
- Install BepInEx 5 for SULFUR.
- Put
DeadeyeInstinct.dll into:
BepInEx/plugins/
- Start the game once.
- Edit the generated config file:
BepInEx/config/ryuka.sulfur.deadeyeinstinct.cfg
If upgrading from prototype builds, remove the old config:
BepInEx/config/ryuka.sulfur.strongaimassist.cfg
Compatibility
Deadeye Instinct is designed around the game's existing aim assist, input, camera, and weapon trigger pipeline.
Normal Magnet / Natural path:
AimAssist
→ rotationPullDelta
→ InputReader
→ CameraController
HardLock path:
UnitManager.GetAllNpcs(false)
→ hostile target filtering
→ target priority scoring
→ ExtendedCameraController.RotateTowardPosition()
AutoFire path:
Holdable.SetTrigger(bool)
→ Weapon.HandleShootingUpdate()
→ Weapon.AttemptShoot()
→ Weapon.Shoot()
Deadeye Instinct does not directly patch projectile spawning or projectile flight behavior.
Notes
This mod is intended for SULFUR's single-player / PvE gameplay.
The default presets are intentionally strong. Use Low or Medium if you want a lighter assist feel.
HardLock and AutoFire are experimental strong-assist features and may require tuning depending on weapon, enemy type, and level layout.
