Speed-Adjustable Minecarts

This is a mod that allows for precise adjustment of minecarts. It only affects minecarts ridden by players, so there's no need to worry about interference with your redstone machines. The speed adjustment range is from 0.1x to 10x of the original speed (it is not recommended to set high speeds on curves, as it may cause derailment). It also includes a minecart mute option, freeing you from the rumbling noise of minecarts. It works on servers as well and only needs to be deployed on the server side. Command permissions require OP privileges.

The mod commands are as follows:

Speed Commands: /renxin speed set <multiplier> - Set speed
/renxin speed get - Check speed
/renxin speed reset - Reset speed

Mute Commands:
/renxin mute set true/false - Set mute
/renxin mute get - Check mute status
/renxin mute toggle - Toggle mute status
