Signal Radar

Signal Radar

A handheld radar with the screen on the device itself. NeoForge 1.21.1. Only NeoForge is required; KubeJS, Manhole Travel, Lootr, FTB Teams and JEI are optional.

Hold the radar and read its little CRT: a sweep turns around you, blips light up as it passes, far targets sit on the rim with an arrow. Hold right-click to raise it to your face and read the name, distance and compass direction of the blip you are looking at. It runs on Forge Energy, so keep it charged, or it shows NO SIGNAL.

Features

• Five tiers: upgrade modules raise range (256 to 4096 blocks), precision (less position fuzz) and addon slots (1 to 5). Upgrading keeps the energy and the installed addons.
• Addons (sneak + right-click opens the addon menu) choose what shows up:
  • Container: chests, barrels and other storage.
  • Ore: ore veins, coloured by ore type.
  • Biosign: animals and villagers.
  • Structure: the nearest known structures.
  • Motion tracker: moving hostile mobs only (still ones stay hidden), with a beep that speeds up as they close in.
  • Manhole (with Manhole Travel): manholes your network has not opened yet.
  • Lootr (with Lootr): Lootr containers you have not opened yet.
  • Team (with FTB Teams): online teammates in your dimension.
  • Battery: detects nothing; up to 8 stack in one slot and each adds 10000 FE of capacity (configurable). Removing batteries loses the energy above the new capacity.
• Last death marker built into every radar.
• Energy: every scan costs FE, and every addon adds to it. Any charger that supports Forge Energy items works, at its full speed (no charging limit by default).
• Server-authoritative: the server decides what you see. Distant blips wobble by a tier-dependent fuzz and show ??? until you get close.
• Cheap: structures are searched one per tick and cached, block scans have a budget, nothing runs unless a radar is held.
• JEI info pages for the radar, the modules and every addon.

For modpack makers

• Targets are datapack JSON: data/<namespace>/signalradar/target/<name>.json, reloaded with /reload. Four locators: pos, structure (id or tag), entity (type and/or scoreboard tag) and block (id or tag). Each target has a minimum tier, colour, reveal distance, optional stage or unlock requirement, found radius and a "hide when found" switch.
• Found flow: a player who gets close with a radar marks the target as found. That sets the stage signalradar_found_<target name>, fires an event and shows "Signal acquired". Wire it to quests.
• KubeJS: server events scan, targetFound, upgraded, addonChanged; a SignalRadar binding (tier, energy, addons, unlock, lock, found, target position); and a startup event to register your own addons bound to a block tag, entity tag, structure tag or container detector, with tier, radius, refresh, colour, FE cost and category. Bad input never crashes a script, it is logged and ignored.
• Commands (op): /signalradar settier, charge, addon, unlock, lock, resetfound, targets, clearcache.
• Config: capacity and charge speed, scan cost and period, range, fuzz and slots per tier, and for each addon: enabled, minimum tier, radius, refresh, colour and FE cost. Ore blip colours can be overridden per material.
• Tags: signalradar:ore_targets (default #c:ores), container_targets, biosign, trackable and the worldgen tag scannable_structures (the structures the Structure addon looks for; empty by default = all structures of the dimension).
• Mods can hook in: Forge Energy, NeoForge events (RadarScanEvent, RadarTargetFoundEvent, RadarUpgradedEvent, RadarAddonChangedEvent) and a small API class.
• The display rectangle is read from assets/signalradar/radar_screen.json, so resource packs can restyle the model.
• Client options: motion beep, display brightness, height arrows.
