Struct BeaconState 

pub struct BeaconState {
    pub(crate) levels: i32,
    pub(crate) primary_power: Option<MobEffectRef>,
    pub(crate) secondary_power: Option<MobEffectRef>,
    last_check_y: i32,
    checking_beam_sections: Vec<BeamSection>,
    pub(crate) beam_sections: Vec<BeamSection>,
}

Mutable beacon state shared with the menu’s data slots.

Fields

levels: i32

primary_power: Option<MobEffectRef>

secondary_power: Option<MobEffectRef>

last_check_y: i32

Y level reached by the in-progress beam scan; below pos.y() restarts the scan.

checking_beam_sections: Vec<BeamSection>

beam_sections: Vec<BeamSection>

Sections from the last completed scan. Emptiness is the beacon’s activity gate.

Implementations

impl BeaconState

const fn new() -> Self

pub(crate) fn filter_effect( effect: Option<MobEffectRef>, ) -> Option<MobEffectRef>

pub(crate) fn validate_effects( primary: Option<MobEffectRef>, secondary: Option<MobEffectRef>, levels: i32, ) -> bool

Rejects effect combinations the vanilla client UI cannot produce for levels: tiers gate both slots, and a secondary additionally needs a full pyramid or the same effect.

fn required_levels_for(effect: Option<MobEffectRef>) -> i32

Returns the 1-indexed tier that unlocks effect, 0 for None, or i32::MAX for effects not in BEACON_EFFECTS.
