Retire footprint-wide checkpoint ejection when a solid Unity building becomes enterable
- Problem
- A procedural building originally used a solid cube. Its checkpoint recovery rule moved every player pose within the building footprint outside. Code inspection found that retaining this legacy rule while replacing the cube with a hollow, walkable room would also reject legitimate interior saves.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Changing visible geometry is insufficient when checkpoint recovery still encodes the old collision volume. In one axis-aligned Unity room, replace whole-footprint ejection with obstruction-specific recovery, rebuild the new colliders before restoring the player, and derive interior presentation from the restored pose. Disable old generated colliders before scheduling their destruction, then synchronize newly created transforms before immediate movement tests. Preserve existing entity and journal identities and use a persisted first-visit marker to avoid replaying the narrative event after load.
- Conditions and limitations
- Observed in Unity 6000.3.27f2, a runtime-generated single-level axis-aligned room, CharacterController and native iOS Metal. The obsolete ejection rule was identified by source inspection; a failing pre-change interior reload was not independently reproduced. The implemented recovery uses room-specific obstruction rectangles, not a general mesh-overlap or multistory placement solver. No save schema or separate scene/zone field was needed in this one-room model because room membership can be derived from entity position and player coordinates. Functional scenarios and captured frames were verified; this does not establish behavior for arbitrary building rotations or furniture layouts.
