Astronomic Expansion Addon (1.2 Only)

This is the first addon to implement customized behaviors for eight new items in-game. Most of the items enable some kind of extra ability. For example, the Panic Necklace will give you an incredible speed boost and the Elytra Starter will boost you up into the sky towards the stars. A great thing is that neither of the new items replace any vanilla items!

How to obtain the new items?

The Astronomic Items can be obtained by trading with an Astronomer or the Magician. They are new villager types which can be found spawning in villages. They are dressed the same way as a Cleric.

You can also use the following text chat command to obtain the items: /give @p yellow_flower 1 [1-8]

List of New Items & Behaviors

All of the following items are sold by the Astronomer. Most of the new items provide the player a new ability while holding it.

  • Astronomic Items (Astronomer Villager)
    • Star Powder – The Astronomer can craft multiple of them into a Fallen Star. It can be used on zombies to turn them into Galactic Zombie bosses.
    • Fallen Star – Base ingredient for all other items.
    • Star Sword – Deals 10 attack damage and boosts your health and speed.
    • Shield – You can’t die while holding this item. However, you’re speed is drastically decreased.
    • Umbrella – Reduces your gravity while holding it. This means you won’t die from fall damage.
    • Fire Amulet – Immune to fire damage while holding it.
    • Elytra Starter – Launcher you into the air if you jump while holding it. Switch to another item to stop the boost.
    • Panic Necklace – Speed boost while holding it.
  • Magic Items (Magician Villager)
    • Vampire Potion – Hold the item in your hand when it’s night to turn into a vampire! (+3 hearts, +2 damage, increased speed)
    • Werewolf Potion – Hold the item in your hand during the night to turn into a werewolf! (Night: +5 hearts, +4 attack damage, increased speed & saturation. Day: -2 hearts)

There is no way to undo your transformations (e.g. werewolf or vampire) at the moment.

Here I first used the Elytra Starter to boost myself up into the air. I then switched to the Umbrella item to fall safely down to the ground.

The Panic Necklace is extremely useful if you need a quick escape as it will greatly increase your speed while holding it.

The Shield will make you invincible to all damage. Actually, I died after 10-15 seconds of them attacking me. But it did help keep me alive longer than otherwise possible.

The Magician sells Empty Extract Bottles. Use them on bats or wolves to extract their life essence. Then kill a bat or a wolf to obtain a Vampire Tooth or a Wolf Fell. You can then trade these items with a Magician to obtain a Vampire Potion or a Werewolf Potion.

Hold the Vampire Potion or the Werewolf Potion when it’s night to turn into either creatures (or rather gain powers/abilities which relate to them).

  • Vampire Potion – Hold the item in your hand when it’s night to turn into a vampire! (+3 hearts, +2 damage, increased speed)
  • Werewolf Potion – Hold the item in your hand during the night to turn into a werewolf! (Night: +5 hearts, +4 attack damage, increased speed & saturation. Day: -2 hearts)

Other Useful Info

  • Use an Empty Extract Bottle to capture the Life Essence of wolves and bats
  • Give a villager a Star Flower to turn him into an Astronomer
  • Give a villager Star Powder to turn him into a Magician
  • Polar Bears drop Polar Bear Fell
  • Ocelots drop Ocelot Fell
  • Vindicators drop Corrupted Souls
  • Baby Zombies drop Corrupted Flesh
  • Endermen drop Corrupted Hearts
  • Fiery Potion – Trade this item in combination of Corrupted Souls, Corrupted Flesh OR Corrupted Hearts to craft a Sword Effect Pigmen (available: damage, health, speed)
  • A weaponsmith sells bonus items which you can get by trading a lot with him:
    • Steel Ingots (random number of iron ingots and Fiery Potion)
    • Diamond Hammer (2 sticks & 4 diamonds)
    • Steel Hammer (2 sticks & 4 Steel Ingots)
    • Star Hammer (2 sticks & 4 Fallen Stars)
    • Steel Sword (1 stick & 2 Steel Ingots)
    • Emerald Sword (1 stick & 2 emeralds)
  • Important:
    • Please note: All Villager transformations should be done before you open his trading inventory for the first time, otherwise you won’t have access to his first trades
    • Mob drops might be broken in the 1.2 beta which leads to this feature not fully working

Notes from the creator (solvedDev):

I am tricking the game in order to add these new items. You might experience bugs or unexpected behavior. I will try my best to fix them but some stuff won’t be possible to fix.

This addon isn’t ready yet: It’s still in development. I’ve planned the addition of more mobs & blocks through this addon in the future.

How this works:

All items are retextured & renamed flowers. This means you can place them down in flower pots, on grass or dirt. The very difficult thing to do was the custom item behavior. You might think: “How were you able to add new behaviors to items?” but you have to think the other way around: I haven’t added item behavior, I am changing how the player entity works! 🙂



  • Tweaked various items
  • Polar bears now drop Polar Bear Fell
  • Ocelots now drop Ocelot Fell
  • Vindicators now drop Corrupted Souls, Baby Zombies drop Corrupted Flesh and Endermen drop Corrupted Hearts
  • Added Fiery Potion – trade this item in combination with one of the above listed three items to craft a Sword Effect Pigment (available: damage, health, speed)
  • Combine the Sword Effect Pigment with your Star Sword to upgrade it
  • The weaponsmith now sells some bonus items to which you get access through trading a lot with him:
  • Steel Ingots! (random number of iron ingots & Fiery Potion)
  • Diamond Hammer! (2 sticks & 4 diamonds)
  • Steel Hammer! (2 sticks & 4 Steel Ingots)
  • Star Hammer! (2 sticks & 4  Fallen Stars)
  • Steel Sword! (1 stick & 2 Steel Ingots)
  • Emerald Sword!  (1 stick & 2 emeralds)
  • All of these items (except the steel ingot) are weapons!
  • Updated the tutorial world: New “Wall of Items”-section and a guide to all these new items…


Recommendation: Install the resource pack as a Global Resource Pack in your game settings. This will enable the possibility for custom loading messages and splashes.

  1. Download Resource, Behavior & World .McAddon
  2. Activate the packs for a world in-game

    dude hope im first comment btw can you make a counter strike addon?

    • solvedDev says:

      That’s not what I am interested in… In addition custom range weapons aren’t possible. I tried to add some for this addon.

      • Counter Strike official says:

        thats cool just a thought if you are empty wity no ideas


      • Jetmaster231 says:

        0_0 who are u Counter strike offical?

      • Jetmaster231 says:

        OHHH i get it now you cant change the custom items i see now, i was just asking you to replace the snow ball and egg to be like different weapons aw yes this addon needs weapons

      • KILLERd7r says:

        What he might mean is add weapons like counter strike to the game of Minecraft my friend made a map and he said a counter strike addon would be so useful in many ways as well helping him with it.

  2. Pdtheyoutuber says:

    Does that mean Mojang will stop this feature from working?

  3. Xbow003 says:

    This is about as close as iOS will get to real mods great job

    • solvedDev says:

      No, the plugin API is on its way… It should enable full support for new items, mobs, blocks,…

      • Sefferdoodle says:

        If custom Crafting Recipes come out would you upgrade this addon to have custom crafting recipes for the addon? Also I had a thought while I did a Mod-Review for this, if steak has data values, you could make like new food items, not sure if this would work, just a thought

  4. cookiebuild3r says:

    Cool, but when I try to download it I am spammed with malware and viruses.

  5. Radoric says:

    Sir, you are a genius! Here is a challenge for you. See if you can make some of these items equipable. It would make this addon much better. Also, here is a suggestion. Try using items that are not placeable, and use textures that cannot be found in minecraft. One way to get these items is a command like this. /give @p dirt 1 10. This normally would give you the regular dirt, but this dirt does not stack with other dirt’s, because it has a different number, in this case, 10. You can retexture these other items.

    It crashes my game when I add this add on and play the world. Can you fix that please?

    Nice 😉

    Hey editor, why wasn’t I credited for my builds on pixel playground? I asked Fizzman, and he said he would, then I wasn’t there.

    Awesome job! I’m on IOS so it’ll be a while before I download it, but this definitely revolutionizes the way addons work and can be used! Amazing work though… I look forward to seeing the future updates for this addon! 🙂

    • solvedDev says:

      Yeah, I have an iOS device as well and I really wanted to get it working for MCPE 1.1. I tried multiple times but I would probably need to completely rewrite it. That would be far too much work.

  11. SuperiorZod says:

    This guy is a genius. WOW.

  12. MinecraftGirl_374 says:

    How do you get it on creative mode?? Please help (I’m on MCPE Beta

    • max1024 says:

      Addons cannot add items to creative inventory, so you can use only /give command.

    • sanik says:

      These items are using unused block Ids,so solved dev replaced their textures with custom behaviors and textures. In simpler terms, they can’t be found in the creative menu.if you want the villagers, try using /summon villager multiple times.

  13. pro redstoner999 says:

    i made a less glitchy version using command blocks but I do not have textures

    • solvedDev says:

      Doing it with command blocks is relatively easy but has a few huge downside:
      >Command Blocks are placed in the world, so a lot of them would cause lag.
      >You cannot work with the player entity with commands like you can with commands. (e.g.
      increasing damage without using an effect)
      >Setting up the command blocks in your world is not as easy as installing an addon.
      >It is very hard to keep track of which command block does what: Json is a lot easier to work

  14. Vladu11 says:

    Amazing behavior! Where did you find this “on_environment” behavior?

    • solvedDev says:

      It’s used quite often in vanilla Minecraft… e.g. Strays & Spiders

    • England is My City😂😂 says:

      Hi Vladu11!! What is your next project Would it be Addon or Map?? BTW LIKE YOUR NEW Map The Illusion of Terror Really Creepy and Scary Too

  16. NoorMuhammadAkmalSulaiman says:

    Can you make an custom armor addon with special abilities? Btw, very nice addon 😀

    • solvedDev says:

      Probably not. I am really using all my time to push this project development forward now.

      • NoorMuhammadAkmalSulaiman says:

        Oh, ok 😊

      • Sefferdoodle says:

        Continue this as long as possible, this is the best addon I have ever seen for Minecraft Bedrock, I hope you will continue this as it will become the most popular addon on this site if you continue developing this! (My third comment in 5 minutes, I really enjoy this addon… 😉

  17. Jason says:

    Nice job

  18. PedroCrafter23 says:

    But it is not work. Can you help me

    • solvedDev says:

      I am happy to help other people but this comment section isn’t the right place to talk. Feel free to contact me on twitter! 🙂

  20. Minecraft Champ says:

    Cool addon although I did find a bug when I attacked almost every mob that isn’t a armor stand and I don’t 1 shot just floats up into the air even through blocks including villagers also I think that the sword should actually give the mobs levitation or the debuf that only parrots get when you give them a cookie (it’s called fatal_poison) also I got a good block idea add a star blockfor the star texture you could use the end sky texture bc that has stars also I hope to see a feature of this addon that isn’t being used rn get used in the next update and that feature is [
    //Golden air bubbles item – not in use
    “astroExp:golden_air_bubbles”: {
    “minecraft:type_family”: {
    “family”: [ “player”, “holds_golden_air_bubbles” ]

    What I thought you could use this for is (of course an item) to have unlimited breath underwater but the downside to this is unable to breath on land also I think a few more things should have a downside the things I think should now have a downside are the sword you move fast have more health but attack slower, and the Panic Necklace let’s you move fast but have a little bit less health the Umbrella I think is sort of bugged bc when you fall from a height that would normally kill you you go to half a heart so your able to get 1 shot by anything also the Elytra Booster you can have a firework or a firwork star used to trade for it bc (for me) it shows I can do the trade and when I do it takes the firework rocket and the fallen stars but when I place the Elytra Booster anywhere in my inv it vanishes so really the Astronomer is stealing so you can’t use an item that has nbt data like the firework rockets or there stars used to craft them just use like quite a few fallen stars and star powder or you can only get it by commands also plz don’t have at least the sword be a flower bc when fighting like baby zombies you sometimes accidentally place your weapon and if you die and don’t find it it’s lost forever but if there’s no way to fix that then ok but let’s hope the new item thing for addons come out VERY soon

    • solvedDev says:

      Wow, thanks for the feedback!

      The golden_air_bubbles aren’t yet in this addon because the corresponding component is very buggy at the moment. That’s why I left it out.

      I cannot make the sword something un-place-able because we cannot at items at the moment. 😐

      I tried messing around with the attack effect, but it doesn’t seem to work on the player.

      • Minecraft Champ says:

        Oh btw is alright of I like edit some things in this addon to help you out a bit? Bc I do have some items in mind that are hard to explain but are pretty cool and I might even be able to help out on some bugs so is it alright? Btw I’m not a texture creator and also not very creative on the textures but I am on the items and blocks themselves

        • solvedDev says:

          Sorry, I am preferring to work on this addon on my own. You’re free to shape the addon by suggesting features for me to implement.

          • NinjaX3 says:

            I’ve tried to make custom item and it work fine for me.Except for one problem,it make some of item texture corrupted.I don’t know how to make custom armor yet.

    Man Theres Alot Of Bug But I know you can Fix it Solvedev

    • solvedDev says:

      What bugs do you mean? I currently have no bugs on my list. (I fixed to more issues for the next update) Please explain in detail which issues you’re experiencing! 🙂

      • Sefferdoodle says:

        This may just be 1.2 beta, but i’m experiencing a glitch where if you place an item down, it becomes a different item from this mod, I have no other addons installed. (I call this a mod because it is that sort of tier

  24. AntoineMCDL says:

    Cool but I cannot access the tutorial world. (LG K 7) May you put in a .zip later?

    • solvedDev says:

      The world automatically installs with the behavior & resource packs! Check your world screen after the installation the game installed the behavior & resource pack. If it still doesn’t show up, try restarting Minecraft.

      In case that all doesn’t help you with your problem, you can rename the .mcaddon file to .zip, unpackage it and double click on the .mcworld file. But as I said, this shouldn’t be necessary.

    Why does this addon have to be for 1.2 that’s dum I want it for 1.1.5 BECUASE I’m on iOS so it’s not fair for us iOS users because the android users have the beta stuff

    • Anonymous says:

      Because this addon only works with stuff added into the next update, it’s not the creators fault or the minecraft devs fault either it’s just because apple likes to take forever to release updates and if you could get this addon then it wouldn’t even work cause it NEEDS the behaviors added in the 1.2 update to even work
