EquipmentSlots Mythicmobs wiki

Vanilla Commands can do what mythic can't

Update to EquipmentSlots, to have similar capabilities to /execute if items entity @e[limit=1] <slot_type> or <slot_type>.<slot_number>. The fact that I can target some slots with Vanilla Commands while I cant do that with Mythicmobs is infuriating.

I'm trying to recreate a more advanced version of the "Disorganization" potion buff from RLcraft with Mythicmobs. "Disorganization" randomizes the target's inventory with the current items that's in the inventory; I'm trying to make my version work with blockentities too.

Implementation

Adds the Vanilla feature, and expands upon it.

• All containers that Vanilla Commands can target
• Improve bags and custom storage container's customizability and compatibility

vanilla feature oversimplified summary

Slot type:

slot_ype is like the post code, it tells Minecraft approximately where the thing is.

Slot number:

slot_number is like the house number, it tells Minecraft exactly where the thing is; but there can be duplicates in a single entity.

ie: The player, there are 3 different "slot_number=0" with them being Hotbar, Inventory, and Enderchest

Why this instead of Mapped Index:

gives a namespace for backpack, and custom storage blocks, allowing for more customizability and compatibility

---

Bags & Furniture Container

• The slot_type will be/return with the bag/furniture's internal item name.
• The slot_number will be/return with a numerical value with similar logic to the Vanilla container.<slot_number>, just with the ability to go above 53.

can utilize the suggested condition `- EntityContainsItem` to check for an item that's in a bag, making quivers possible.

- skill:MyCustomSkill ?EntityContainsItem{item=arrow;slottype=MyCustomQuiver;slot=*}

strict	exact, e	Whether the matcher should more strictly match the target item	false

To check if a block contains an item

Condition	Type	Description
EntityContainsItem	Entity	Checks that targeted entity's inventory slots to see if there is a similar item

4 New Targeters

Usage

- SetItemOption{option=StackSize;value=12} @TargetItemSlots{slottype=hotbar;slotnumber=0;targetconditions=[ - isplayer true ]}

Usage

Dynamic Mob Behavior based on "some variable"

There are currently no condition for checking for items inside mounts, with this we'll be able to assign weight to items, which can change the speed for mounts.

"See" what's in a chest

There are currently no way of checking what's in a Blockentity, <target.block.data> DOES NOT RETRUN CONTAINER DATA

If mobs can "see" into the inventories of blockentities

The amount of cool things that this can do, imagine a creeper that doesn't go after the player, instead it went after the chest full of Netherite

Value

Quality of life, and limitless possibility.

Priority

High, this is something that's doable in Vanilla. I'd like to be able to do everything within mythic instead of needing to rely on a datapack and a billion scoreboards.
