Updraft

This updraft datapack allows operators to summon "updraft entity markers" that levitate entities above the marker, give slow falling to entities just outside of the levitation effect, and create particles if desired. Designed to be used both on its own, or with other datapacks.

To Use:
Summon a marker entity tagged "in.updraft" at the desired location of the updraft with the appropriate configuration parameters.

Configuration:
  data.strength: integer

• Required. Determines the height of the updraft (strength x 10 blocks), and determines the levitation effect strength if data.levitation is not specified.

  data.levitation: integer

• Optional. Sets a static strength for the levitation effect throughout the updraft.
• If unspecified, the strength of the levitation effect will be determined by data.strength and by distance from the updraft entity marker. The levitation effect starts at a strength of data.strength, and decreases by 1 for every 10 blocks above the updraft entity marker.

  data.particles: string

• Optional. "none" by default.
• "all": Full particle effects as long as the updraft entity marker is loaded.
• "nearby": Full particle effects as long as a player is within 32 blocks horizontal distance.
• "minimal": Single particle effect as long as a player is within 32 blocks horizontal distance.
• "none": No particle effects.
• WARNING: Using "all" or "nearby" when data.strength is set to a high number (>50) can cause extreme lag. For updrafts far beyond build height, use "minimal" or "none".

Examples:
/summon minecraft:marker ~ ~ ~ {Tags:[​in.updraft],data:{strength:5,particles:"all"}}
/summon minecraft:marker ~ ~ ~ {Tags:[​in.updraft],data:{strength:20,levitation:10,particles:"nearby"}}
/summon minecraft:marker ~ ~ ~ {Tags:[​in.updraft],data:{strength:200,levitation:128}}
