Sign creation no longer scans the block it's mounted on. Instead,
placing a "[Stargate]" sign starts a pending link (shown as "Punch the
gate" on the sign) and the next block the owner left-clicks within
gate.link-timeout-seconds and gate.max-link-distance becomes the scan
seed. This lets the sign act like a DHD console standing apart from
the gate instead of being physically attached to the frame.
- Gate now stores the punched link block's coordinates (link_x/y/z)
so restarts re-scan from there instead of deriving a seed from the
sign's attachment, which no longer applies.
- New GateLinkListener handles the punch and reports scan failures
via the existing diagnostic messages; also clears pending state on
disconnect.
- Exit-location facing is now derived from the punched frame block's
position relative to the iris, since a WallSign facing is no longer
guaranteed to exist or be relevant.
Chevrons no longer need to be built out of a special block - the plugin
picks gate.chevron-count frame blocks evenly spaced around the scanned
ring and remembers their resting material, so a chevron can rest as
plain obsidian (matching the rest of the frame) and only reveal itself
by swapping to gate.chevron-lit-material while dialing/open. Restoring
on close now puts back the original block instead of a fixed material,
so alternating decorative frames (e.g. obsidian/gilded blackstone) are
preserved exactly.
