Entity Counter

This block which have the appareance of a redstone lamp with a little screen on it can be interacted with to show a mini interface constitued by 2 number field, 2 plus symbol button and 2 minus symbol button. You can increase of decrease the number of entity required to turn on the block but also detection radius. If the count is met in the radius, it emits a redstone signal. This thing allow everyone, in its survival or on a server to control the number of mobs in farm or make an alarm system noticing you if you have an intruder (mob or player). Without needing a command block that is locked behind using a give command/creative. The other use can be a cleaner, if there are two many items on the ground, it activates a water dispenser as example. The third use, it can be a cave detector! Indeed, you play solo survival, so technically, most of the time, your sphere of influence is 1 entity, you. But if you put this block to 2 entity for radius of 15 (which is maximum) and it turns on, it means there is a mob, and so, a cave if you are mining straight into only stone.
