Ground Designator Scope
by liyuu
Ground Designator Scope lets a spyglass mark a ground point under the crosshair, and the marked position is then passed to compasses bound to that scope.
What it does
Holding the scope and left-clicking designates the ground point under the crosshair. Compasses bound to the same scope are synchronized to that point, so they keep pointing at the designated spot. Binding happens by sneak-right-clicking with the scope in the main hand while the compass sits in the offhand. The binding ID is stored so the link persists between uses.
Targeting uses the real ground rather than the default raycast, which would otherwise hit cockpit glass of Sable physical structures. Vanilla spyglass zoom behavior is kept, and the server recalculates the raycast target, so clients and servers agree on the designated point. Left-click designation breaks blocks only as the vanilla action would. The mod also works with Coordinate Compass for coordinate display.
Key features
Ground designation
Left-clicking with the scope designates the ground point under the crosshair.
Compass binding
Sneak-right-clicking with the scope in the main hand binds a compass held in the offhand to the scope.
Synchronized compasses
Bound compasses are updated with the same designated point, so they point to the same location.
Real ground targeting
The raycast ignores Sable physical structures, such as cockpit glass, and targets the real ground.

Use cases
Navigation with compasses

Coordinate Compass pairing
The mod pairs with Coordinate Compass so the designated location can be read as coordinates.
Who it’s for: Players on NeoForge 1.21.1 who navigate with compasses and want to point them at a spot chosen with the spyglass. The mod needs to be installed on both the client and the server.

What the author says
Ground Designator Scope adds a ground-designation spyglass and bound compass support. Sneak-right-click with the scope in the main hand and a compass in the offhand to bind; while using the scope, left-click designates the ground point under the crosshair and syncs it to all compasses with the same binding ID.
