code/Cursor
The pointer's position over the viewport, as a uv from 0 to 1 with its origin at the bottom-left.
Geometry
A reading of one pointer, taken once per frame before any actor event fires, so every actor in a frame agrees on where the cursor is. The value is a flat viewport coordinate, not a position in the scene: to put something under the cursor in 3D you want code/CursorRay and code/RayPlaneIntersect instead. Available inside a geo/Actor only, which is the only network whose runtime binds a cursor.
