## Resolves a screen position (or a dart's world position) to a board sector,
|
||||
## and applies modifiers there.
|
||||
##
|
||||
## THE BOARD HAS 21 MATERIAL SLOTS: sector_1 .. sector_20, plus "bulls".
|
||||
## The bull slot covers inner AND outer bull — they move together.
|
||||
##
|
||||
## Two ways to find which sector was hit:
|
||||
##
|
||||
## A) BY FACE INDEX (default, robust)
|
||||
## Raycast returns face_index. Map face -> surface. The surface's material
|
||||
## name IS the sector. No trigonometry.
|
||||
## Survives the board rotating, tilting, or having its sectors remapped,
|
||||
## because we're asking the geometry, not calculating from an angle.
|
||||
## Requires ConcavePolygonShape3D (trimesh) collision.
|
||||
##
|
||||
## B) BY ANGLE (fallback)
|
||||
## atan2 on the local hit point. Cheap, works with a box collider.
|
||||
## Survives rotation (to_local undoes the transform) but NOT sector
|
||||
## remapping — if Mjolnir makes every sector a 20, the angle still says
|
||||
## "this is the 6".
|
||||
##
|
||||
## Use A. It's the only one that supports a moving/mutating board, which is the
|
||||
## whole point of the modifier system.
