Detailed Description

Represents an entity's position in the world (plus its orientation).

Entity positions are determined by the following:

X, Z coordinates (giving left/right and front/back coordinates on the map)
Y offset (height; entities always snap to the ground, then are offset by this amount)
'Floating' flag (snap to surface of water instead of going underneath) As far as the simulation code is concerned, movements are instantaneous. The only exception is GetInterpolatedTransform, used for rendering, which may interpolate between the previous and current positions. (The "Jump" methods circumvent the interpolation, and should be used whenever immediate movement is needed.)

Orientations consist of the following:

Rotation around upwards 'Y' axis (the common form of rotation)
Terrain conformance mode, one of:
- Upright (upwards axis is always the world Y axis, e.g. for humans)
- Pitch (rotates backwards and forwards to match the terrain, e.g. for horses)
- Pitch-Roll (rotates in all directions to match the terrain, e.g. for carts)
- Roll (rotates sideways to match the terrain) NOTE: terrain conformance is currently only a local, visual effect; it doesn't change the network synchronized rotation or the data returned by GetRotation
Rotation around relative X (pitch), Z (roll) axes (rare; used for special effects) NOTE: if XZ rotation is non-zero, it will override the terrain conformance mode

Entities can also be 'outside the world' (e.g. hidden inside a building), in which case they have no position. Callers must check the entity is in the world, before querying its position.
