About this Mod
Per-Minecart Max Speed Customiser
Per-Minecart Max Speed Customiser is a Fabric mod that gives you precise control over individual minecarts in your world. Instead of relying on the minecartMaxSpeed gamerule, this mod allows you to set custom maximum speeds for each minecart entity, independently.
Using the Minecart Wrench tool included in the mod, you can fine-tune the speed of minecarts one by one, enabling advanced and creative minecart-based transportation systems tailored to your needs!
⚠️ Important: Minecart Improvements Experiment must be enabled

How to use
- Equip the wrench provided by the mod.
- Crouch (sneak) and right-click on a minecart this will bring up a UI wherein you can configure the max speed.
You can also directly summon a minecart with a specific speed using the following command:
/summon minecart ~ ~ ~ {CustomMaxSpeed:100.0}
If you don't manually adjust a minecart's speed, it will default to using Minecraft's minecartMaxSpeed gamerule for determining speed.
