Structure spawner generator

(Download: MC 1.11+ | older versions)

Structure spawner generator is a simple MCEdit filter to convert any Minecraft structure to a single command which spawns the structure itself.

Installation

To install Structure spawner generator as a MCEdit filter, simply download structure_spawner_generator.py from here. Start up MCEdit and click on the Config Files button: MCEdit's configuration directory will be opened. Open the Filters subfolder. Inside, put the file you just downloaded.

Usage

Once you've opened the desired level inside of MCEdit, go ahead and select the structure you want to turn into a command. Click on the Filter item and from the Filter drop-down select Structure spawner generator. You should get something like this:

Tweak the settings as you wish, and when you're done, press Filter. If Save the command to a file instead of to a Command Block isn't selected, you'll see that a Command Block ready to be imported will be on the upper right of the MCEdit window. Click on it and import it wherever you wish: the Command Block will contain the command to spawn the structure!

Filter options

Structure generation

• Relative position, Forward offset, Left offset and Up offset: these options determine where the structure will be spawned relative to command execution point.
• Include air: should air blocks be explicitly placed when the structure gets spawned? For example, if the structure gets spawned on an uneven terrain, should the area be cleared first?
• Include blocks and Include entities: these two options behave in a pretty similar way. If Include blocks is enabled, you can choose if you want to spawn selected entities along with the structure using Include entities. If you want just to spawn the selected entities, select only Include entities.
• Include null block data: if a block has 0 as data value and no data tag, it will be placed by the structure spawner using setblock <x> <y> <z> <block>. Enable this setting to place the block using setblock <x> <y> <z> <block> 0 instead.
• Include "gamerule commandBlockOutput false" command and Include "gamerule logAdminCommands false" command: if enabled, gamerule commandBlockOutput false and/or gamerule logAdminCommands false command(s) will be executed before spawning the structure. It is recommended to leave Include "gamerule commandBlockOutput false" command enabled, as it disables the chat spam that would come along structure spawning. Also, if the structure uses a lot of 10Hz+ Command Block clocks, it is recommended to enable Include "gamerule logAdminCommands false" command to avoid creating giant log files and console spamming.
• Add initialization commands and Add finalization commands: these two options serve to execute certain commands before and/or after structure spawning. For example, it might me useful to set up some scoreboard objectives before the structure gets spawned. If one or both of this options is enabled, you will be prompted to select a file containing the commands you want to execute before/after spawning the structure. The selected file has to be a text file, containing one command per line.
• Blocks to enqueue: some blocks depend on other blocks to exist. For example, a torch needs to be placed on a block. To make sure everything gets spawned correctly, Blocks to enqueue contains a list of crucial blocks which have to be placed once everything else got placed. The list should already be fine, however if you see one or more blocks popping off after structure spawning, you can add their ID here.
• NBT tags to ignore: as you might know, some blocks (for example Command Blocks) require additional data through the use of so-called NBT tags (like the command contained in the Command Block, its state, …). To save on characters, some tags can safely be ignored. If you are an NBT pro, you'll find this option really useful to strip some tags you identify as useless.
• Save the command to a file instead of to a Command Block: as the name suggests, if this option is enabled, the command to spawn the structure will be saved to a text file instead of to a Command Block. This option can be extremely useful, as the command saved to file will be formatted in such a way that it will be much easier to edit manually afterwards. If this option is enabled, you will be prompted to select a text file to which to save the command.
• Ignore maximum Command Block command length: Command Blocks have a maximum command length of 32500 characters. If this limit gets exceeded, you get an error message and no command will be generated. However, if you think you have only slightly exceeded this limit, you can enable this option to take a look at the command and see what might could be done to make it less than 32501 characters long.

Box generation

• Generate surrounding box: many One Command creations are just a bunch of Command Blocks enclosed by a box with some clickable signs on the front. If you are creating one of these One Commands, you could create this box yourself. However, this and the following options provide an easy way to do so without too much hassle. If this option is enabled, the generated structure will be enclosed by a box of blocks.
• Box wall material block, Box wall material data value, Box floor material block, Box floor material data value, Box ceiling material block and Box ceiling material data value: the materials to be used to generate the surrounding box.
• Add box signs: if enabled, you will be prompted to select a text file describing the signs to be placed on the front of the box. The file has to have the following format:

  <x>, <y>
  <Text 1>
  <Text 2>
  <Text 3>
  <Text 4>
  <Command 1>
  <Command 2>
  <Command 3>
  <Command 4>
  
  [Repeat for as many times as needed]
  

  <x> and <y> determine the 2D-position of each sign on top of the front wall of the box. 0, 0 indicates the lower left of the wall.
  <Text n> is the text to be placed on the n-th line of the sign. It can be an empty string, some text or a JSON formatted string.
  When clicked, a sign can execute up to four commands. <Command n> determines the n-th command and can be empty if required.
