    posted a message on How to Use the /execute Replacement Commands for 1.13+

    The replacment for /testfor is something like this:

    /execute if @p

    It's not that hard. Put that in a repeating command block with a comparator on it you will get redstone signal out based on the number of qualifying entities found.

    To be honest that's a relatively complex mechanic. It would involve scoreboards and many commands. MCStacker could generate some of the commands but it couldn't make the complete solution.

    Thanks. Lots of things to address there. I'll try to rectify these things soon.

    As you may know by now, MCStacker is getting a rewrite. Internally the old site at mcstacker.bimbimma.com was getting too hard to maintain. So I decided to start from scratch with a better plan. It's well on it's way to including the functionality of the original and now has some features that the original site does not have. The way MCStacker has been designed is to focus first on the commands and then make the form dynamically show you options relevant to your previous selections. So depending on what entities, blocks or items you've chosen, will determine what other options become available. The trade-off here is that a lot of the cool functionality is buried in the system and many people may not fully know what can be achieved with this generator. So here's a short summary of the specific options available for some items and blocks.


    Player Skulls

    Written Book (JSON)

    Writable Book

    Sign (JSON)

    Fireworks / Firework Charge

    Spawn Eggs (All specific Mob NBT)

    Armor Stand

    Potion (Splash, Lingering & Tipped Arrow)

    Chests, Trapped Chests & Shulker Box

    Banners and Shields

    Knowledge book


    Wall and Standing Banners

    Enchanting Table



    Brewing Stand

    Chests, Trapped Chests & Shulker Box





    Command Blocks

    End Gateway

    Flower Potion


    Mob Spawner (all entites and specific NBT)

    Wall and Standing Signs

    Note Block


    Structure Block


    All of them and most of their respective NBT

    Some Background

    I just though I'd take the opportunity to give some more justifications to what this rewrite is all about and bit about what might come next.....

    There one big problem with the original site was that it is it was never really designed properly from the start. It just started as a basic tool to stack entities with very little other options. It just began to evolve. The problem with this is that often when a new version of Minecraft came out or I decided to add in more functionality, I would have to code in changes which would then introduce bugs elsewhere in the code. The code then became messy, bloated and hard to maintain. IE: technical debt. MCStacker was my first major JavaScript project. Now that I've learned the language better, the new MCStacker will be more responsive and light-weight which will result in quicker load times.

    Another thing that was missing was an /entitydata command. When coding a tool like MCStacker. You're supposed to try and reuse code throughout the whole system. Due to a lack of foresight, using check boxes to control NBT flags with a 0b or 1b was not a good idea. It made sense for a summon command generator. But this code could not be reused in the context of an entitydata command where you might want to turn a tag off. In the new MCStacker you will find 'select' controls which default to 'unset' but then can be used to set something to either True or False. Many people had been asking me to do an entitydata command, but I delayed making one for the above reason. The good news is that /entitydata now done.

    The layout is very different. I've opted for a very simplistic top-to-bottom layout. This was to help things run faster internally but the logical grouping of related controls have been sacrificed here. Sorry about that. One thing that's cool about the new layout is that way the complex stacks can be created. You simply add one or more passengers to an entity. Entities which are passengers can also have their own passengers. And so on. For now the ability to move entities around in the stack is not available. I'll try to rectify that at some stage. Other little usability features included are a tick/seconds toggle on fields which are for ticks. When seconds are chosen. The value will get multiplied by 20. The command output window is drag-able. The new site has more color so that it's easier to see where sections start or end or where forms are nested inside of other forms.

    For now the ability to save commands like on the original site is not available. I have technically ambitious goal to eventually build a command parser into MCStacker which will import a command so that it can be edited. This would also be used for the loading of saved commands. It's going to be extremely difficult and might not happen at all. I might just try to support more commands instead. Stay tuned for a poll on this. You can have you say and help me prioritize.

    You might be wondering by now about the original MCStacker. It's going to stay where it is but I will not be updating for future versions of Minecraft unless they are really simple things. MCStacker.net will be kept current.

    Lastly I would just like to thank everyone who ever contacted me with feature requests bug reports or just to say thanks. All of you in some way motivated me to improve MCStacker. All you awesome creative map-making type people are just the best. Respect!!!

    posted a message on 1.8 to 1.9 Summon Converter

    If you have an adventure map or server which has command blocks with summon commands in them, they are probably going to fail when played with 1.9. I don't think the 1.9 version of Minecraft is going to convert these automatically. To solve this I created a summon command converter which looks for Tags: Riding, Equipment, DropChances, HealF and converts them to Passengers, ArmorItems, HandItems, ArmorDropChances, HandDropChances and Health.

    It's still a manual process. But you shouldn't need to recreate all of the summon commands.

    You can find it at : http://bimbimma.com/summonconverter/

    posted a message on 1.9 - NBT Changes and Additions

    I'm having some problems getting SpawnPotentials to work. I can get the first Spider to spawn. But after that a pig will appear in the Spawner.

    /setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:"CaveSpider",CustomName:"Jack",CustomNameVisible:1},SpawnPotentials:[{Type:CaveSpider,Weight:1,Properties:{CustomName:"Jack",CustomNameVisible:1}},{Type:CaveSpider,Weight:1,Properties:{CustomName:"Jill",CustomNameVisible:1}}]}

    posted a message on Giant Mural Generator - Import png, jpg, gif - no mods, no schematics, no downloads

    Importing images into Minecraft is not a new idea, but as far as I know it could only be done with mods or with MCEdit with schematics. It is now easy to create giant mosiacs/murals with this online generator and a little bit of redstone/command block voodoo.

    The generator is available here http://bimbimma.com/minecraftmurals/

    Here's a few screenshots of images I've generated:Frank Zappa

    Mushroom Cloud

    I would like to see some of your creations. Post yours as a reply.

    posted a message on Summon command says it works but nothing appears
    The sub type goes after the Damage tag (even though it has nothing to do with damage)

    If it has a zero, then you can just leave it off. Like this:
    For 1.8.1 /summon Item ~ ~1 ~ {Item:{id:stonebrick,Count:1}}
    For 1.7.9 /summon Item ~ ~1 ~ {Item:{id:98,Count:1}}

    But if it does have a number that is not zero then it would look something like this:

    For 1.8.1 /summon Item ~ ~1 ~ {Item:{id:stonebrick,Damage:3,Count:1}}
    For 1.7.9 /summon Item ~ ~1 ~ {Item:{id:98,Damage:3,Count:1}}

    Oh, ok. I never actually tested it. I assumed it would work ok with a Horse but it may not.

    I've made a Summon command for you on MCStacker to demonstrate the setting of the yaw. You do need to enter the pitch also though.

    posted a message on CustomNameVisible in /summon won't work!
    I generated this on http://bimbimma.com/mcstacker

    It works fine.

    /summon Villager ~ ~1 ~ {CustomName:"Bob the smelter",CustomNameVisible:1,Profession:0,Invulnerable:1}

    Initially it looks like you were trying to format/color the text for the name but that does not work via commands(I wish it did) . But anyway the Villager's name needs to be surrounded with double quotes.

    posted a message on Trying to figure how to summon an item with the summon command but nothing is working right
    Just remove the pickupdelay part and it will work fine:

    /summon Item ~ ~ ~ {Item:{id:grass}}

    But maybe it does not work because you did not specify the count. So this should work:

    /summon Item ~ ~ ~ {Item:{id:grass,Count:1}}

    posted a message on QR Code generator for your maps or server
    I just finished work on my QR Code generator. To use it you head over to my webpage at http://bimbimma.com/qrcode/ and enter a URL into the field. A QR Code is then generated along with a very complex summon command that produces the QR Code. A little bit or basic redstone magic is required also. Instructions are on the page. It's not that hard to use. Attached is a picture of a QR Code that the generator made.

    posted a message on Command block summon help!
    This summon command should work but I havn't tested it:

    /summon EntityHorse ~ ~1 ~ {CustomName:"Invisible Horse",CustomNameVisible:1,Type:0,SaddleItem:{id:329},Variant:0,Attributes:[{Name:generic.movementSpeed,Base:0}],ActiveEffects:[{Id:14,Amplifier:0,Duration:72000}]}

    The 1.8 version of the command is:

    /summon EntityHorse ~ ~1 ~ {CustomName:"Invisible Horse",CustomNameVisible:1,Type:0,SaddleItem:{id:saddle},Variant:0,Attributes:[{Name:generic.movementSpeed,Base:0}],ActiveEffects:[{Id:14,Amplifier:0,Duration:72000}]}

    This command was generated with my MCStacker summon command generator: http://bimbimma.com/mcstacker/

    You can summon many different kinds of entities with it with lots of different options.
