E31C: Build Entity Spawn Record
Used by the routine at Process_Tracked_Enemy_Entity.
Reads the direction byte from (IX+02), indexes the direction animation offset table at Direction_Animation_Offset_Table by direction × 4, and writes five bytes to the entity spawn buffer at C511: the animation type byte (28 + direction), the direction-adjusted Y coordinate, the direction-adjusted X coordinate, and two further table bytes via two LDI instructions. Called from Process_Tracked_Enemy_Entity.
