Cart Radar
by xdenll
Cart Radar is a client-side Fabric utility that warns players when stacked TNT minecarts come close, built for Cart PvP fights.
What it does
The mod scans the area around the player and detects overload minecarts, meaning stacked TNT carts, so that a player gets advance notice of explosive setups. Warnings appear either as a classic on-screen message list or as world-anchored 3D icons projected over the minecarts. The minimum number of stacked TNT minecarts needed to trigger an alert is set exactly in the configuration, so the threshold can be matched to a particular server's play style.
Cart Radar is built specifically for Cart PvP, where overload crossbow setups and trap carts have been used to produce unexpected explosions. Built-in distance culling and FOV projection limit which markers are drawn, which the author describes as keeping the game responsive in large battles. The mod requires Fabric API, and Cloth Config API and Mod Menu are optional, with Mod Menu offering in-game configuration. It is published for Fabric only, for 1.21.11, and the source code is released under the MIT License.
