FormShift is a quest-like form system for characters, a unified volume that swaps player/AI pawns on enter/exit, supports timed forms and revert modes, and exposes clean Blueprint hooks for health/inventory transfer and effects, fully replicated for multiplayer.

Video Showcase / Quick start Guide

It makes character form swapping simple, consistent, and multiplayer-safe.

Drop a FormShift volume (or using a blueprint node) in your level, choose which pawn class to swap into, and FormShift handles:

• Server-authoritative spawn & possession

• Optional swap on enter, exit, or both

• Optional timed forms that revert after a duration

• Clean Blueprint events so you can transfer health, inventory, and other custom state however your game needs.

Key Features

🔁 One Volume, Many Behaviors

• Swap on Enter – Step into the volume and immediately transform into another character blueprint.

• Swap on Exit – Cross the boundary and switch to another class when leaving.

• Swap on Enter & Exit – Use different forms when entering and leaving a zone.

• All behaviors are optional and controlled by one FormShiftVolume, and can be also done using a blueprint node.

🌐 Multiplayer & Replication First

• All form swaps run on the server (HasAuthority guard everywhere).

• Uses standard AController::Possess and replicated pawns.

• No client-side spawning, no hacky possession, clients just see the new pawn replicated properly.

• Safe by design for co-op, PvP, or shared world games.

Typical Use Cases

• Dungeon / Arena Zones

  • Player becomes a different form (e.g. demon, mech, ghost) when entering a specific arena, and reverts afterward.

• Stealth & Disguise

  • Step into a disguise zone to become a guard character; revert to original form when the timer ends or on exit.

• Puzzle / Ability Gates

  • Certain areas require a unique movement/ability character. Enter the zone → swap to special form → revert later.

• Multiplayer Events

  • Server-triggered events that force everyone in a region into a specific form (mutations, curse zones, etc.).

Performance:

FormShift is lightweight and event-driven: it only does work when a pawn enters/exits a volume or a swap/revert happens. All logic is C++ and server-side, so even with many players and volumes the performance impact is minimal.
