A quantum inspired gameplay toolkit for reality bending physics and puzzles.

Designed for observation puzzles, shifting environments, linked objects, probability-driven interactions, and experimental game mechanics.

Add a QRT Component or Preset → Configure Behavior → Connect Gameplay

Quantum Reality Toolkit (QRT) gives Unreal Engine developers reusable components, placeable actors, volumes, and ready-made Blueprints for building unusual gameplay. Create a bridge that moves when nobody is watching. Link distant objects so an impulse affects both. Phase a barrier out of the way, switch between room layouts, or build a puzzle around superposition and measurement. Start with the included presets, then connect QRT’s Blueprint functions and events to your own interaction system.

Calculation

Use individual systems or combine them to build connected physics and puzzle interactions.

• Weighted probability for object state selection.

• Observation checks to hold or release state changes.

• Linked impulses for paired physics objects.

• Gravity acceleration and ballistic trajectory prediction.

• Qubit amplitudes and phase for measurement probabilities.

• Probability and collision checks for tunneling.

Usage

(1) Place a preset or add a component to your actor.

(2) Configure its settings in the Details panel.

(3) Assign targets and links where required.
(4) Call its Blueprint functions from a button, switch, trigger, or your existing interaction system.

(5) Respond to its events with your own doors, lights, sounds, objectives, or UI.

Example Uses

(1) A statue that changes position whenever the player looks away.

(2) A bridge held in place by an observation camera.

(3) A temporary doorway that stays open until the player moves clear.
(4) Two remote physics objects responding to a shared impulse.
(5) A chamber that switches between alternate layouts.
(6) A qubit puzzle where phase changes affect the measured outcome.
(7) A barrier-crossing challenge with probability and blocked-landing checks.

Note: Most issues arise from incorrect collision settings, missing target references, or observation locks preventing state changes. Ensure physics simulation is enabled for physics-based interactions, and keep destination spaces clear for phase returns and tunneling.
