Companion to L.3a (a1c27b3) which ported the velocity-reflection bounce.
Previously the CreateObject parser did `pos += 4` for both Friction and
Elasticity floats — silently dropping the wire data so every entity got
the PhysicsBody constructor default (0.05 elasticity, 0.5 friction).
Server-set bouncier surfaces or stickier objects therefore felt
identical to inert walls on collision. Inelastic projectiles via
PhysicsState bit 0x20000 (already plumbed in Commit A) had no per-
object elasticity to override.
Now the parser captures the floats, surfaces them on Parsed +
EntitySpawn, leaving the values at default (null) when their
PhysicsDescriptionFlag bits aren't set. Subscribers (e.g., the
remote-entity dead-reckoning path, future spell-projectile rendering)
can apply them when they wire elasticity to PhysicsBody.Elasticity.
The local player's PhysicsBody is constructed at controller init,
not from a CreateObject — so this commit alone produces no
user-visible local-player change. Effect lands when remote/projectile
physics consume EntitySpawn.Elasticity.
Files:
- CreateObject.cs:284-294: declare friction + elasticity accumulators.
- CreateObject.cs:467-487: parse floats instead of skipping.
- CreateObject.cs:543-555: propagate to Parsed via both return paths.
- WorldSession.cs:67-71: extend EntitySpawn record.
- WorldSession.cs:665-668: pipe through to subscribers.
Tests: 1491 still pass.
