Passengers from Spawn Eggs

Changes in this version:

• Updated namespace from pfse tp passengersfromspawneggs to remove ambiguity and potential for clashing with other resource packs, mods and data packs

• Updated pack format to 64 for Minecraft 1.21.7 and 1.21.8

Note

• The casing of the replace_with_entity and nbt tags in the marker's data NBT is not finalised
• Due to accessibility to the data tag in all entity types, the system may change to instead use data.passengers as the source of the passengers of the ridden entity/entities, while all other data would stay (eg. give @p minecraft:spider_spawn_egg[entity_data={id:"minecraft:spider",Health:2.0f,data:{passengers:[{id:"minecraft:skeleton"}]}}]).
