Spawn a new entity on the client or server. The new entity's position and team is copied from the entity which has the badger:presentation_event component.
You can also spawn multiple entities with an array: "entity": ["badger:mob_zombie", "badger:piglin_runt", "badger:mob_wolf"]
Example:
"on_world_hit": {
"entity": "badger:pres_entity_test"
}
