Ambient entities

   

PC/Console/Mobile/tModLoader-Only Content: This information applies only to the PC, Console, Mobile, and tModLoader versions of Terraria.

Not to be confused with Ambient objects.

Ambient entities are objects that appear and move around in the background, and cannot be interacted with in any way. They are displayed depending on the time of day, biome, and weather. While some can be seen regularly, others are only displayed rarely. Clouds can be considered background entities although they are not affected by biomes. Ambient entities' motion speeds up with time.

Notes

• The Meteor ambient entity will only be displayed if the condition for the meteorite biome to spawn was fulfilled between dusk and 11:40 PM, which includes the random chance each night. It will always start falling in the background at 11:40 PM.
  • Even if circumstances would prevent meteorite landings (i.e., no new meteorite biome would actually be generated), the background meteor will still appear when the conditions are fulfilled.

Trivia

• The bats more accurately represent the bats from the Bat Scepter rather than the bat enemy.
