This is a clientside utility mod for Cart combat that allows you to use the tnt minecarts + bows to their full potential without the hassle of rattling your brain to the core. This is intended for small scale singleplayer worlds and small scale servers.

Requires Fzzy Config & Mod Menu for configuration

If installed serverside, This mod acts as its own anti-cheat and searches for its own packet (cartcore:cartcore-rep) to remove you from the server. This packet will not be present if you compile the mod from source or get it from my patreon. Patreon
The 1.21.4 & 1.21.1 versions of this mod WILL BE exclusive to my Patreon as well.

Here is a rundown of everything included within this mod (Keep in mind that also every feature has tick variance to minimize detection):

features (entirely configurable):
Insta-carting (All you have to do is look somewhat downwards and press right click! The mod will even release your bow at the right time to ensure a proper insta-cart is possible)
Cart overloading (Extension of instacarting, Places multiple carts on the same block, allowing for a bigger detonation and sometimes carts being launched into the air)
Crossbow Carting (KEYBINDABLE if you attempt to shoot the ground with a charged crossbow (or you press your keybind), automatically place a rail, then tnt minecart, flicks your viewpoint downwards just enough to place a flint and steel, then flicks your viewpoint back upwards. Then, and only then, does your original shot register. Igniting the tnt minecart and exploding it instantly.)
Intuitive Sound Effects (custom vanilla-based sound effects when any cart tech is performed.)
Tick Variance (allows you to configure the tick randomness of most of the features, on by default and is intended to avoid macro detection )

Reccomended settings per server as of 2/22/2026 (❗meaning high risk)

If you're a modpack creator, feel free to include this in your modpack if you want to encourage lesser-skilled players to use and cart pvp, as this gives anyone access to the full potential of cart pvp in vanilla Minecraft.
