C++ state machine, Blueprint interactions and a native courtyard map.

SKILL TREE

From rules
to player feel.

I focus on C++ gameplay systems that work with Blueprint. Clear state, predictable behavior and useful designer controls guide these projects.

  1. CORE

    Make the rules explicit.

    State machines, fixed-step simulation and validated transitions keep gameplay behavior understandable.

  2. GAMEPLAY

    Put the player in control.

    Input, movement, interactions and feedback connect those rules to a playable experience.

  3. BLUEPRINT

    Leave room to create.

    Native functions and Blueprint events give presentation and content their own place to evolve.

PLAYTEST LOG

Verified, not just shipped.

  • ALPINE FLIGHT

    The flight model gives bit-identical results for identical inputs, which is what makes client-side replay work. A test covers it, and a network harness reports prediction corrections under latency, jitter, loss and reordering.

  • VECTOR

    Builds as a plugin inside Lyra 5.4 with 0 errors and 0 warnings. The movement rules pass standalone tests, including a strafe-jumping simulation.

  • LANTERNFALL

    48 assertions cover both story branches, cell requirements, unique pickups and save snapshots. A native UE5 run completed the relay branch, and the clinic branch completed a native viewport run.
