Particle block tests

A particle can expire by the block it is in: minecraft:particle_expire_if_in_blocks ends it inside any block of a list, minecraft:particle_expire_if_not_in_blocks outside all of them; the vanilla bubbles keep to water with the second (water, flowing_water, bubble_column). Observed · the vanilla particle files of bedrock-samples v1.26.60.5 Packs use them as probes: an invisible particle placed beside the emitter survives only in (or out of) the listed blocks, and an event on its expiry or at the end of its life starts the visible effect. Observed · a third-party resource pack

The lists name blocks by their identifiers, without states. Observed · the vanilla particle files of bedrock-samples v1.26.60.5

Names current Bedrock no longer has

The vanilla block registry of 1.26.60.5 lists 1,466 blocks. It has none of the old names that blocks were split from or renamed from: minecraft:leaves and leaves2 (now one block per wood: oak_leaves, acacia_leaves…), grass (grass_block), skull (one block per head: skeleton_skull, zombie_head…), chain (iron_chain), coral_fan and coral_wall_fan (one per coral: tube_coral_fan…). Nor has it dark_oak_standing_sign: the dark oak sign is darkoak_standing_sign. frame, glow_frame (item frames, which are blocks in Bedrock) and border_block are current. Proven · every name above looked up in the 1.26.60.5 registry

Does a block list still match a removed name through an alias?

Whether a particle’s block list resolves a removed name to the blocks that replaced it is not published. If it does not, a list naming minecraft:skull matches no head at all. Inferred
