In the Minecraft game, if the player wants to collect the made portal and use it at any time, then he or she needs special game instructions to complete it. The player needs to build a nether portal first.
Answer: /setblock~~-2~air0destroy .
1. First, players need to obtain the block code and pass the password /give@pcommand_block to build the nether gate. This is also a special operation in the game.
2. Then the player orders the block to be placed in a suitable position, and then enters some special commands, /setblock~~-2~air0destroy.
3. After completing the above operations, players can drop the made portal and pick it up again for easy use next time.
