Movement Control System

function utils:motion/calc

summon fireball ^ ^ ^.5

execute store result entity @n[type=fireball] Motion[0] double -0.00025 run scoreboard players get @s utils.motion.mx
execute store result entity @n[type=fireball] Motion[1] double -0.00025 run scoreboard players get @s utils.motion.my
execute store result entity @n[type=fireball] Motion[2] double -0.00025 run scoreboard players get @s utils.motion.mz

Alternative method using data storage:

function utils:motion/storage {"value":"-0.00025"}

summon fireball ^ ^ ^.5

data modify entity @n[type=fireball] Motion set from storage utils:motion motion

Entity Data Management

Data Creation

# Direct path
/function utils:entity/storage/set {"path":"lives","data":3}
/function utils:entity/storage/set {"path":"name","data":'"lullaby6"'}

# Array manipulation
/function utils:entity/storage/append {"path":"deaths","data":1}
/function utils:entity/storage/append {"path":"deaths","data":2}
/function utils:entity/storage/append {"path":"deaths","data":3}

Processing Stored Data

/function utils:entity/storage/function {"function":"namespace:say_lives"}

Contents of say_lives.mcfunction:

$say $(lives)

Data Removal

# Direct paths
/function utils:entity/storage/remove/data {"path":"lives"}
/function utils:entity/storage/remove/data {"path":"name"}

# For arrays
/function utils:entity/storage/remove/first {"path":"deaths"}
/function utils:entity/storage/remove/index {"path":"deaths","index":1}

Constant Values

The library provides constants from 0 to 1000:

/scoreboard players get 1 utils.const

Advanced Predicates

• Location: can/see_sky, in/biome/<biome_name>, in/structure/<structure_name>, in/dimension/<dimension_name>
• Weather: is/raining, is/thundering
• Physical Status: is/falling, is/flying, is/ground, is/sneaking, is/sprinting
• Randomization: random/<chance> with probability descriptions (0.1 = 10%, 0.5 = 50%)

Usage example:

/execute as @s if predicate utils:is/on_fire run say I'm on fire :(

Advanced Item Management

• Item Counting: count/add/<number>, count/remove/<number>, count/set/<number>
• Visual Customization: enchantment_glint_override, max_stack_size, item rarity settings
• Functionality: repair_cost, tooltip configuration, cooldown timing

Usage:

/execute if items entity @s weapon.mainhand minecraft:raw_gold run item modify entity @s weapon.mainhand utils:smelting
