Hello dear users,I have a question how can I do so that every second the mob checks if there is a player within a radius of 4 blocks from the mob, if there is no player within a radius of 4 blocks, then it checks within a radius of 12 blocks if there is, it does a certain procedure. (As you can see I tried to do it, but it works for me so that the mob shoots if the player is in 4 blocks) Thanks in advance.
