Attributes

OPP registers 45 read-only attributes on every player, mirroring its conditions and refreshed at the end of every server tick. It also adds one settable attribute, drag, on every living entity. You can read them without any power:

attribute @s origins-powerful-powers:time_airborne get
execute store result score @s sprint run attribute @s origins-powerful-powers:sprint_ticks get
execute store result score @s speed10 run attribute @s origins-powerful-powers:velocity_y get 10

The last number (10) is /attribute's scale. Scores are whole numbers, so scale up to keep decimals.

Where to use them:

• In commands and functions, through /attribute and execute store.

• In Origins, with origins:attribute. Attributes are synced to clients, so this is how to use OPP values in hud_render conditions and other client-checked places (see page 1).

  jsonCopy

  {
    "type": "origins:attribute",
    "attribute": "origins-powerful-powers:crouch_depth",
    "comparison": ">=",
    "compare_to": 1
  }

• In variable code, by storing the attribute in a score and reading it with Scoreboard.get.

Rules:

• Players only, except drag.
• Yes/no values are 1 or 0.
• Values are clamped to the range below. For example, time_since_last_meal stops at 1,000,000,000.
• Leave them unchanged, except drag. The base value is overwritten every tick, and a modifier added with /attribute … modifier add stays and makes get return a wrong value.

The list

Two conditions map to more than one attribute:

• The velocity condition's axes are the three velocity_* attributes.
• look_angle is split into look_pitch and look_yaw.

The voice-chat condition is_whispering is the attribute is_whispering_voice.

These conditions have no attribute: has_attack_target, projectile_age, last_damage_type, is_sleeping, stat, last_hit_was_crit, last_damage_was_crit and has_power_tag, plus the bi-entity conditions.

last_death_distance is the one attribute with no condition. Check it with origins:attribute, for example "comparison": "<=", "compare_to": 16 for "within 16 blocks of your last death". Add a second check with ">=", 0 to leave out "never died" (−1).

Drag

origins-powerful-powers:dragevery living entitysettable

A normal vanilla-style attribute, like generic.movement_speed. /attribute ... base set and Origins attribute modifiers stick.

It replaces vanilla's fall-drag constant: the fraction of downward speed an entity keeps each tick while falling through open air. Swimming, lava, elytra gliding, climbing and the upward half of a jump use vanilla physics. The default 0.98 is the vanilla constant. The drag value sets the terminal velocity, as in the table below.

attribute @s origins-powerful-powers:drag base set 0.9

Falling caps around 0.72 blocks/tick, down from vanilla's 3.92. It's a permanent, gentler fall, like a weak Slow Falling.

attribute @s origins-powerful-powers:drag base set 0.995

Falling caps around 15.92 blocks/tick, about four times vanilla's terminal velocity.

• Jump height is unchanged. It only applies while the entity is moving downward or standing still, and gravity itself is untouched.
• Modifiers work normally. For a temporary change, add a modifier and remove it later with modifier remove.
• Slow Falling, Levitation, no-gravity and riding keep vanilla behavior. On any tick where vanilla's fall differs from plain open-air falling, OPP keeps the vanilla result.
• Player flying and swimming, and mobs with custom flight or swim code, keep vanilla behavior.
