/// Even with a pomander of sight, the BattleChara's position for the trap remains at {0, 0, 0} until it is activated.
/// Upon exploding, the trap's position is moved to the exact location that the pomander of sight would have revealed.
///
/// That exact position appears to be used for VFX playing when you walk into it - even if you barely walk into the
/// outer ring of an otter/luring/impeding/landmine trap, the VFX plays at the exact center and not at your character's
/// location.
///
/// Especially at higher floors, you're more likely to walk into an undiscovered trap compared to e.g. 51-60,
/// and you probably don't want to/can't use sight on every floor - yet the trap location is still useful information.
///
/// Some (but not all) chests also count as BattleChara named 'Trap', however the effect upon opening isn't played via
/// ActorVfxCreate even if they explode (but probably as a Vfx with static location, doesn't matter for here).
///
/// Landmines and luring traps also don't play a VFX attached to their BattleChara.
///
