It is also possible to teleport minecarts or boats , with players in them. See This Minecraft Forum article for a better explanation of this, and other useful things. By swapping gamemode it is possible to use command blocks and functions in single player outside of creative mode.
The command block only needs to be set in creative, but will still function once back in normal. It can also be used to teleport to certain areas for example a far-away stronghold, a deep mining operation, or a floating island.
If they don't have cheats enabled, open the LAN and set the cheats on , but they can still activate it in Survival mode.
Then, activate the command block with redstone including buttons, levers, and pressure plates , and they will be sent to their destination. The player can set up multiple different teleports. This can also be used when doing a big project that spans over a very large area or if they are transferring chests to from an old house to a newer house.
This section details the applications of the command block in multiplayer. Commands can also be used for flying entities or structures. Most commands based flying machines use command blocks so that when the player turns on an input, it activates certain command blocks. Unlike piston based technologies, however, these cannot be legitimately made in survival as command blocks require set up by an operator in creative mode.
With clever command usage, movement can be controlled by various means such as holding a specific item. The entity, in turn, can be controlled by some other means. This can be done by spawning instantly detonating creepers or TNT below an entity. However, there is a multitude of disadvantages, including:. The equivalent command for versions below 1. It can be applied to a range of scenarios.
That way the player doesn't have to be teleported, but the landscape around them can be animated as the clone commands copy the various animation "frames" near the player sequentially. As mentioned above one can create a lottery but that lottery is usable by the public. A simple edit can change that First create a new objective. Using the "Range" and "Minimum Range" parameters, they can have it teleport players back only when they're a certain distance away.
If player really want to kick it up a notch, poison the player use one of the previous two commands, but replace the first number with This could be a way to get creative mode people to change to Survival and is also really fun to watch.
If the command block is placed after a finish line, it will say the finishers in order. Creating a "Creative Only" zone is possible through command blocks, but it is complex and more of a case-by-case basis. The basic idea would be to create a "fence" of command block affected zones so that, once a player flies in creative through it, they would be changed to survival or adventure mode. Set both blocks to repeat and be self-powered and there should be a fairly "seamless" transition zone between normal and protected.
The gap between the two variables in the reversion block need not be exactly 10 blocks, but a buffer helps for lag concerns in guaranteeing that once left, a player will revert back to survival mode. Do note that if you have a nether portal within the protection zone, that the player will NOT be reverted to survival once they step through, so place a reversion cube of any type Impulse or Repeating in the Nether on the other side of that portal.
It is possible to create a colored, clickable message players can send to anybody. Simply place a comma and space with each addition. If you want other players to be able to click it, use clickEvent. I hunger! This means when the player clicks the text, it will give them a stack of cooked pork. Then just type the value text as a regular sentence, no slashes. If you want an easier job of it, here we have some tools:.
Using coordinate and maximum parameters, players can teleport everyone within a specific area to another specific area. If a certain player has been very nice, regular, or helpful to the server but not quite meeting the requirements to be promoted to an admin, players could have a room full of buttons connected to command blocks with helpful effects, like giving the helpful player a stack of diamonds or a bedrock block, then have it connected to another command block, sending them to the spawn point.
It is very important this room is reinforced with bedrock, hidden, and you can only get in by teleporting to its co-ordinates to avoid abuse. Assuming only admins can get to it, a weather machine can be quite useful, players can turn rain on and off at will.
One of the more helpful uses of this technique would be to use a combination of villagers they run inside when it rains and some form of redstone machinery to create and automatic rain disabler, this would allow you to shut off the rain almost immediately without needing to use the command, or to have an admin present.
By making two similar places on one map, players can have a button activate a command block to teleport them from one to another, while also changing the time of day. This can be used to look like time travel.
This section details the applications of the command block in custom maps. One map that takes advantage of a lot of the features of the command block is the Hypixel's Gladiator Arena in which the fighting system is almost only based on this.
Sometimes it's important in a map to keep the command blocks silent, may it be to keep the magic of the suddenly appearing items in the inventory, or because the channel telling that the player was teleported, it can break the mood of a map.
Using pressure plates or tripwire, make areas like a castle for instance a different difficulty in this instance peaceful.
Note that in multiplayer this will change the difficulty everywhere in the world, and thus may not be desirable. You can make the outside of the house be 8x10 m, and the inside of the house be 8x10 m. Simply connect this to a pressure plate before a parkour level over lava and you don't have to use any kind of chest minecart especially useful when the player has it's full inventory, which is bigger than a single chest.
Many times, a player will be building something, and it will start raining or start to get dark, which both can be disturbing to the player. Fortunately, you can use commands to turn off the rain, as well as make the sun go back to sunrise. Use clear if you want to clear the weather, or rain or thunder , if you would like to toggle on rain or a thunderstorm. Create a hostile mob so it disappears when switching to Peaceful that never despawns if the player is far away.
To do so, use a name tag on the mob or third party software if you are playing in a version previous to 1. Make sure it will keep it pressed infinitely, so make sure surround it with 2 high blocks or fences, so that it can't jump or walk away.
Make a redstone circuit that causes a command block to activate when input from pressure plate ceases to exist. Place a message inside the block that informs the player on chat that the map has been broken and must be redownloaded. This way, switching to Peaceful will cause the mob to vanish and activate the message. You can even make a teleportation command block so that a cheater is banished from the map to a small room without a way out as soon as they switch to Peaceful.
It may be one of the better uses of the Command Block as you don't need silly signs or long books to show the game rules. Just put a bunch of command blocks in lines with repeaters set to two or three ticks to avoid spamming players allowing you to easily remove a chest of books or a large number of signs. Imagine you enter a butchery and you want the butcher to say something. Usually, you might use signs or books, using up room in the butchery and having seemingly random objects strewn around a map.
Maybe a pig behind the counter could even beg for mercy! Let's take another example: you are in a factory and an alarm suddenly rings and says in chat it will explode. Having it in the chat, especially if the text is long, keeps the stressful mood; the same thing works for bomb timers.
The situation might feel tenser if the chat displays ' Last but not least, it makes it easier to create a Quest System. Let's say the player gets in a butchery. The player gets to the pig that is standing on a stone pressure plate, that turns off when the pig is dead. So, when the player gets back to the butchery, it activates another circuit containing yet another RS NOR Latch and two command blocks with two commands. Along with that, don't forget to use the p command so the butcher says the player's name.
You helped me a lot killing that pig. Custom villagers selling whatever you want can be created with command blocks. Custom villagers are not available through Minecraft: Bedrock Edition. The part labeled "Buy" is what the villager is accepting as payment, the part that says "sell" is what he's giving in return. You can change the maxUses to if you never want the offer to run out, or to 1 if you want to make it a one-of-a-kind item.
Note that the first item there the gold sword has an out of range enchantment sharpness 9. Yes this works, but always research what exactly the enchantment does before making an out of range one as some stuff does nothing or even does negative effects respiration's "see underwater" side effect makes everything a blinding white at high levels, as if you dove into slush-filled arctic waters.
As for that gold sword, keep in mind that gold swords wear out insanely fast there's a reason people call them butter swords after all. A level 10 Unbreaking enchantment should bring a gold sword up to a decent durability level. Also notice that the other 2 "weapons" are actually a Stick and a Blaze Rod with weapon enchantments on them. Using any non-weapon as a weapon does the same damage as an empty hand 1 damage, aka half a heart but the enchantments on these ones make them the equal of an unenchanted sword.
The advantage is that sticks, blaze rods, or other items is that you can use it infinitely. The same trick can be used with mob heads and respiration 3 to make an infinite durability scuba mask. Pig, cow, or chicken spawners can be placed in the butcher's backyard in a village to create a constant meat supply.
There doesn't seem to be a limit to how many levels of riders you can use. For example, you could create a chicken riding a pig riding a cow riding a horse riding a silverfish riding a villager "Say, that's a mighty odd hat you have on, Farmer Brown".
Keep in mind that you can use p which means closest player in player issued commands as an easy to type 2 character replacement for your own name as the closest player to you will always be you. This code will create a zombie spawner 2 blocks from you in the x direction. Note that the name given for mob spawners in this code minecraft:spawner is the long version and you can leave out the minecraft: part.
The next thing to do is to modify the spawn data. Spawn data is what tells the spawner you want a non-standard version of a monster, such as a zombie with a diamond sword and a chain helmet.
Because of the fact that none of those 6 parameters from the last example are used, they will all be defaults. Note that there are now two types of item slots, Hand and Armor. So, if you want your custom mob to have a helmet, you have to specify all 5 slots, but if it's just boots, you can leave off the other 3. Likewise, if you want them to have leg armor. Remember that creatures that burn in sunlight are safe if they have a helmet on, although it damages the helmet instead.
As for the count tag, most codes can get away with leaving it out; however, it is important. An item without a count tag is a stack of zero, better known in the community as a "Ghost Item". In Java Edition , it can execute multiple times in the same game tick if "UpdateLastExecution" is set to false. In this case, it does not check whether it has already executed in this game tick. If the chain command block has been activated when triggered, it also updates its success count : If in "Conditional" mode, if the command block behind it didn't execute successfully, it sets its success count to 0.
Command blocks execute commands with OP level 2. Its success count is 1. Command blocks cannot be pushed by pistons. They also cannot be pushed or pulled by sticky pistons. Bedrock Edition : [ needs in-game testing ]. In Bedrock Edition , a command block's block data specifies its orientation and condition mode. A command block has a block entity associated with it that holds additional data about the block. The first image released by Mojang of the command block.
The second image released by Mojang showing the block giving glass to the player. Issues relating to "Command Block" are maintained on the bug tracker. Report issues there. Minecraft Wiki Explore.

Jeb began tweeting of a new block he had created to start expanding Adventure mode. He began posting pictures, ideas and hints of what the block can do. Added command blocks. Command block success can now power a redstone comparator. Command blocks renamed with an anvil now use their name instead of in the chat.
Pressing Esc in a command block will exit its GUI. Command blocks are no longer mineable in Survival. Command blocks are no longer damaged by explosions , except by blue wither skulls. The character limit when inserting a command in a command block has been increased from to 16, Using a third-party editor allows the player to reach 32, characters.
