DNDLN's Automobility Hitboxes Fix
Few things are as frustrating in Minecraft as building a beautiful car with the Automobility mod, only to discover that you cannot open the door, climb inside, or even break the vehicle. This usually happens on multiplayer servers, where optimization mods and the vehicle hitbox system clash and leave your rides in a broken, unusable state. DNDLN's Automobility Hitboxes Fix is a small utility add-on built specifically to solve that exact problem.
What This Add-On Actually Does
Automobility gives players functional cars, but each vehicle relies on a separate hitbox entity to handle collisions and interactions. When performance mods interfere with how those hitboxes are tracked, the game loses the connection between the car and its hitbox. The result is a vehicle that looks fine but refuses to respond to any interaction.
DNDLN's Automobility Hitboxes Fix takes a refreshingly simple approach. It runs a single scheduled function that removes every active vehicle hitbox and then respawns them on a repeating cycle of roughly 45 seconds. Because the hitboxes are recreated from scratch, their state is refreshed and all normal interactions return: entering, exiting, and destroying vehicles work again.
Why the Refresh Approach Works
- Broken hitboxes are cleared instead of patched, so stale data cannot linger.
- The cycle repeats automatically, so new vehicles are covered without extra setup.
- No configuration screens or commands are required from the player.
- The fix targets only Automobility hitbox entities, leaving other mobs and entities untouched.
Supported Versions and Loaders
DNDLN's Automobility Hitboxes Fix is distributed as both a mod and a datapack, which makes it flexible across setups. The mod build is aimed at modern Minecraft releases running on the Fabric loader, while the datapack variant works on any world or server that supports datapacks, including vanilla-based multiplayer environments. If you are running a Fabric server with Automobility installed, the mod version is the cleaner choice because it loads automatically with the game.
If you prefer to keep your mods folder tidy, the foxygame.net launcher is worth a look: it lists DNDLN's Automobility Hitboxes Fix in its add-on catalog alongside the Automobility dependency, so you can add both to a compatible profile without hunting down matching files yourself.
How to Install DNDLN's Automobility Hitboxes Fix
Installation is quick whether you choose the mod or the datapack. Follow the path that matches your setup.
Installing the Mod Version
- Make sure the Automobility mod is already installed for your Minecraft version.
- Download DNDLN's Automobility Hitboxes Fix and place the jar file in your mods folder.
- Launch the game through your Fabric profile and confirm the add-on appears in the mod list.
- Join a world and test a vehicle that was previously unresponsive.
Installing the Datapack Version
- Open your world folder and locate the datapacks directory.
- Drop the datapack file inside, then run the reload command in-game.
- Verify the pack is active with the datapack list command.
- Wait for the first refresh cycle and try interacting with a car.
The same steps apply on a server, though you will need operator permissions to reload datapacks and access to the server files for the mod route.
Important Notes Before You Install
The author describes this project as a personal test utility rather than a polished release. It is not affiliated with the creator of Automobility, and it is not recommended for players who are not experiencing hitbox problems. If your vehicles work perfectly, adding this fix offers no benefit and simply introduces an extra repeating function to your world.
It is also worth remembering that the fix refreshes hitboxes on a timer rather than instantly. In the moment a hitbox is cleared, a vehicle may briefly behave oddly, but the next cycle restores normal function. On busy servers with many vehicles, this periodic cleanup is usually invisible in practice.
Final Thoughts
DNDLN's Automobility Hitboxes Fix is a narrow tool with a narrow purpose, and that is exactly its strength. If optimization mods have turned your Automobility cars into unusable props on a multiplayer server, this add-on gives you back the ability to drive, enter, and dismantle them without abandoning your modpack. Download DNDLN's Automobility Hitboxes Fix for Minecraft, confirm your loader and version match, and keep it in reserve for the moments when vehicle hitboxes break.
