Sens Calc
AKA Sensitivity Calculator
Sensitivity Calculator is a simple mod that based on your misses when using a sword, attempts to calculate what you should change your Minecraft sensitivity to, which can possibly help you aim better.
The more sword rounds you give it, the more accurate it should get.
The mod is simple to use. There are a set of commands to use to enable the mod and get your results:
- /senscalc start (enables tracking)
- /senscalc results (after using /senscalc start and doing a few matches of sword will show you the results, with a balanced sensitivity which is most recommended for a mix of accuracy with speed, highest speed possible which attempts to find a high speed but somewhat good accuracy balance, and best accuracy which tries to find the highest accuracy no matter how slow it is.)
- /senscalc stop (use after /senscalc start to stop tracking and stop the calculator)
Please note that this mod is early in development, its logic for finding sensitivity suggestions may be off, and changing your sensitivity to what it suggests won’t magically fix your horrible aim, just possibly improve it or make it easier to improve.
