The Sci-Fi FPS Pack weapons are project-facing examples built on ShooterCore. The weapon Blueprint owns gameplay state and delegates presentation to its matching weapon-view component. ## Weapon hierarchy | Weapon | Parent | View | Distinguishing behavior | | ------------------------- | --------------------------------- | ----------------------------- | --------------------------------------------------------------------------------------------------------------------------- | | BP\_ARX\_Mk2 | BP\_Shooter\_Weapon | AC\_ARX\_Mk2 | Holograph, charge audio, energy-charge components, and custom fire and aim behavior. | | BP\_Gepard | BP\_Shooter\_Weapon | AC\_Gepard | Standard firearm with a pack-specific view. | | BP\_M97 | BP\_Shooter\_Weapon | AC\_M97 | Grenade timing through GrenadeHandle, UnpinTime, MinUnpinTime, and custom aim rules. | | BP\_Onyx | BP\_Shooter\_Weapon | AC\_OnyxRevolver | Revolver-specific reload presentation. | | BP\_RPG90 | BP\_Shooter\_Weapon | AC\_RPG90 | Collision, scene capture, and backblast components. | | BP\_TP12 | BP\_Shooter\_Shotgun | AC\_TP12 | Shotgun view, holograph, pump action, custom fire effects, and custom aim point. | Start with [Shooter runtime](/sci-fi-fps-pack/unreal/general/shooter-runtime) for the shared initialization, firing, ammo, weapon-view, and shotgun contracts. The sections below explain the product-specific Blueprint extensions. ## ARX Mk2 BP\_ARX\_Mk2 adds a charge state around the inherited use and fire lifecycle. Its view starts charge presentation, maintains the charge loop, then stops charge effects when firing begins. BP ARX Mk2 Event Graph initializing holograph, charge audio, and energy-charge components BP ARX Mk2 Event Graph starting and maintaining the weapon charge state BP ARX Mk2 Event Graph releasing charge into the firearm fire lifecycle BP ARX Mk2 Event Graph returning the pack view component, fire rate, and authored aim point AC ARX Mk2 On Charge Start function starting the ARX charge animation, audio, and energy effects AC ARX Mk2 On Charge Loop function maintaining the ARX charge presentation AC ARX Mk2 On Fire function stopping charge effects and starting the ARX firing presentation ## M97 BP\_M97 holds the grenade through the inherited item-use path, tracks its unpin timing, and releases it through its custom fire behavior. BP M97 Event Graph starting the grenade use state and tracking unpin time BP M97 Event Graph completing grenade release timing and custom Can Aim behavior AC M97 On Equip function playing the grenade equip presentation AC M97 On Use Item function starting the grenade unpin and hold presentation AC M97 On Grenade Loop function maintaining the grenade hold animation ## Onyx BP\_Onyx inherits the standard firearm lifecycle and lets its revolver view choose a reload presentation from the current missing-round count. BP Onyx Event Graph returning the Onyx revolver view and weapon-specific data AC Onyx Revolver On Reload function selecting the appropriate reload animation for missing rounds ## TP12 BP\_TP12 uses BP\_Shooter\_Shotgun and AC\_TP12 for shell reload, pump action, custom effects, and its authored aim point. BP TP12 Event Graph returning the shotgun view and initializing TP12 presentation BP TP12 Event Graph applying the authored aim point, custom fire effects, and pump behavior AC TP12 On Fire function playing the TP12 firing and holograph presentation ## Gepard and RPG90 BP\_Gepard uses the standard ShooterCore weapon and weapon-view flow with its pack-specific assets. BP\_RPG90 adds the collision, scene-capture, and backblast components required by its projectile presentation. Keep weapon-specific behavior in the product child Blueprint or view. Keep fire rate, ammunition, supported fire modes, and aim point on the weapon; keep montages, audio, recoil, animation settings, muzzle flash, and presentation effects on the view. ## Related systems * Use [Gameplay animation](/sci-fi-fps-pack/unreal/general/gameplay-animation) for the settings and procedural graph used by character and weapon animation. * Use [Recoil](/sci-fi-fps-pack/unreal/general/recoil) for recoil data and firing-state hookup. * Use [Animation notifies](/sci-fi-fps-pack/unreal/general/animation-notifies) for frame-specific reload, sound, visibility, and casing events.
