Java mod listed for Minecraft 1.20. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
This is a simple, yet vanilla friendly mod, that aims to bring into minecraft the famous motion detector from the film Alien. This motion detector has a built in compass to help you recognize the direction of the ignal, because it will give an acustic and visual signal for every mob that is in a 60x10x60 box. For every entity, there are 3 distances and sounds: long distance, the sound is low, and low is evn the frequency; medium distance, the pitch gets more high and the frequecy as well; and lastly, close distance, the pitch become very high and the frequecy is also very high, to warn you that something is very close to you.
It is recommended to use it possibly in a close environment, with as litle entities as possible, because you will get a lot of beeps if you are wandering aroud in a forest, since it detects every entity.
This mod is in BETA, so if you stumble across any bugs or errors, please leave a comment, and i will try to fix it :)
