This tutorial walks through the Multiversal Consciousness engine's actual solution: a type-erased Component Registry backed by contiguous arrays, with O(1) entity-to-component lookup, cache-friendly iteration, and a swap-and-pop deletion strategy that maintains array density. All without external ECS libraries.
A deep dive into the design and implementation of a robust input handling system with action-state tracking and a layered tile map renderer with frustum culling, all built from scratch in C++23 on top of SDL3.
Imagine a game where a door unlocked in Reality A must also appear unlocked in Reality B — but the key that opened it only exists in Reality A's inventory, and the agent who picked it up is standing in a completely different position in Reality B. Some state is shared. Some state is independent. And when the player presses one button to switch realities, the entire world must pivot atomically — no system should ever observe a half-switched state during a frame.
What if a game world could exist in two places at once? Multiversal Consciousness is a custom-built 2D puzzle-platformer engine that lets designers create puzzles around parallel realities with shared and divergent state.
