Advanced Shooter System | GC2 Shooter Extensions

GC2 Shooter Extensions is an advanced extension module for Game Creator Shooter that adds body-part aware combat systems, advanced weapon mechanics, suppression logic, overheating, durability, and event-driven shooter gameplay workflows for your projects.

Built specifically for Game Creator 2 Core and Shooter, this package extends the default shooter system with hitbox-based combat detection and a large collection of new Triggers, Conditions, Instructions, and runtime gameplay systems.

The extension introduces custom hitbox shot types that allow accurate body-part detection for headshots, armor hits, limb damage, suppression effects, penetration systems, overheating, weapon condition simulation, and more.

Unlike the standard Shooter workflow, this package routes combat through dedicated extension shot types, enabling advanced combat logic while preserving compatibility with the root Character combat system.

Important Setup Information

Most hitbox-related systems only work with the included extension shot types.

Standard vendor Shooter shot types do not emit body-part hitbox events, suppression events, or advanced hitbox combat callbacks.

Weapons that should use advanced combat functionality must use one of the included extension shot types:

• Raycast Hitboxes
• Kinematic Projectile Hitboxes
• Rigidbody Projectile Hitboxes
• Tracer Projectile Hitboxes

Reload and dry-fire events can still observe the default Shooter runtime state.

The Cover System requires ShooterCover components on cover objects and a ShooterCoverController on the player or character.

Cover animation states and offsets are configured per weapon through the included `Cover States` asset.

Blind Fire from cover is edge-based and should be triggered through the provided cover conditions and instructions before calling the regular Shooter fire instruction.
