Here are the data structures with brief descriptions:

CShCamera	Rows of the pose matrix: right, forward, up, then position
CShCameraOverride
CShComponent	Components
CShEntity
CShHit	Bullets often strike a child part, so root is resolved for you and is the one worth acting on
CShMethod	An object is [vtable, methodTable, ...]; the table is 32 byte entries of crc32(name), index and function
CShNpcArchetype
CShPlayer	Root is the top of the parent chain, and the only position that survives a direct write
CShRay	Dir is a full length vector, so origin + dir is the end of the trace rather than a unit direction
CShRayQuery	A query over the recorded rays
CShShot	A shot, reported on the projectile's first step
CShUiEvent
CShVec3	Metres
CShVehicle
