Radar screen can be configured per dimension.

 

Radar Area is the radius from you that it will check for mobs.

Mob Strength is a value that you can use to be alerted only if a mob have strength higher than this value (keep this value to 0 if you don't want to use it)

Radar will emit sound when a mob is detected. You can ajust the volume level.

​

Show Mob Name will show at your screen the detectedc mob name and mob health / max health.

​

Mob 1 to 10: here you can write mob name that you want to detect. You don't need to write full mob name, just a part of its name is enought to detect.
