In Apex Legends (Source engine modified fork), entity class names (CPlayer, CWeaponX, PropSurvival) are indexed in the global String Table:

1. Find NameList base pointer (0x140000000 + offset_namelist).
2. For entity index $i$:
   $$pNameEntry = (uint64_t)(NameList + (i \times 0x10))$$
3. String at pNameEntry returns "player", "prop_survival", or "npc_prowler".

Instantly identifies whether an entity index represents a player, deathbox, or loot item!

NameList string table indexing is so fast. Zero string comparisons inside the main entity render loop.

Clean explanation of Source engine modified name table.
