The Zombie Summoner in the game "Minecraft" can be used to summon zombies. Players need to use command blocks to make it. So let's take a look at the specific methods for making the Zombie Summoner in Minecraft. For those who are interested, Don't miss it.
One square in front of your friend's base, dig down three squares, place two command blocks, and determine the coordinates of this square as x1y1z1
In the command box below, enter the command /execute @a[x=x1,y=y1,z=z1,r=0.4] ~ ~ ~ summon zombie ~ ~3 ~, set the condition to loop, unconditional, keep it open
Of course, it is still too difficult for the "zombie" security guards who are already "old" to catch up with the naughty kids entering the base, so enter the command /execute @p ~ ~ ~ tp @e[type=zombie in the second command block ] ^ ^ ^-0.5 The condition is set to loop, unconditional, and stays on. In this way, the "security guard" can be directly teleported behind the naughty kid~
In this way, your friend's base will be protected by a bodyguard who is always available and dedicated~
