F key on the ship: teleports the player character to just above the
ship's location and possesses it. F key on the character: possesses
the ship back. Same controller, so possessing one pawn automatically
unpossesses the other.
Notable implementation detail: GameplayStatics::GetActorOfClass
looked like the obvious way to find "the other pawn" at runtime, but
this MCP plugin's pin_defaults mechanism can't correctly set a Class-
type pin (it accepts the string silently but the compiler later
rejects it as an invalid default) -- there's no supported node type
for a class-literal either. Worked around it by adding real object-
reference variables (PlayerCharacterRef / ShipPawnRef) via
unreal.BlueprintEditorLibrary.get_object_reference_type() directly
through the Python escape hatch, marking them instance-editable, and
wiring the actual actor references between the two placed level
instances. Avoids needing any runtime class lookup at all.
BP_PlayerCharacter (Character-based): first-person camera, WASD
movement + A/D turning (same input scheme as the ship), SuitOxygen
stat that depletes each tick, clamped at 0. Not auto-possessed yet --
that's the ship exit/enter transition (next task). Placed one
instance in L_TestFlight near the ship spawn.
Also reverted level gravity to default (-980): FloatingPawnMovement
(ship) never reads world gravity regardless of its value, but
CharacterMovementComponent (this character) needs real gravity to
walk normally. Zero gravity was an unnecessary leftover from Phase 0
that would have broken on-foot movement.
