Reactive Blocks
by P4in
Reactive Blocks gives vanilla blocks new reactions to stepping, jumping and interaction, with several block-specific effects added to the game.
What it does
Blocks such as the Sculk Catalyst, Respawn Anchor, Eyeblossom, Creaking Heart and Decorated Pot respond to a player stepping on them, jumping onto them or interacting with them. Effects include Darkness from the Sculk Catalyst, Regeneration scaled by stored glowstone in the Respawn Anchor, Weakness or Strength depending on whether the Eyeblossom is open or closed, Blindness from the Creaking Heart and a random effect from the Decorated Pot. Some blocks also play custom sounds when a player jumps on them.
The Sulfur Update adds sulfur-related reactions, including Potent Sulfur Block, which applies Nausea II and Slowness, and Cinnabar, which gives Hunger. The Soft Step boots enchantment disables these block effects and the Filtration helmet enchantment disables effects from sulfur blocks. Reactive Blocks requires Fabric API, and its files are published for Fabric only, covering 26.1.2 – 26.2, with ModRelease-1.1.0 for 26.2 as the latest file.
Key features
Step and jump reactions
Blocks apply effects when a player walks onto them or jumps from them, not only when they are broken or placed.
Vanilla block effects
The Sculk Catalyst, Respawn Anchor, Eyeblossom, Creaking Heart and Decorated Pot each receive a distinct effect.
Sulfur block reactions
New sulfur-related blocks such as Potent Sulfur Block and Cinnabar add effects tied to their themes.
Enchantments that cancel effects
Soft Step boots and the Filtration helmet can turn off block effects, with Soft Step also removing damage to attackers.
