The Terraria 1.2 update introduced that make generated worlds varied not only in layout, but in availability of various features as well. What is the fastest way to get a world that has the features I need? Is there a program that can help goad Terraria to generate a world that fits my criteria, or perhaps a tool that will let me quickly tell if a generated world has the features I have in mind?

  • one point to consider is that in Terraria, world names act as seeds. If you create two worlds with the same name it will generate the same. – hedgehog1029 Oct 7 '13 at 19:04
  • @hedgehog1029 that's simply not true. – kotekzot Oct 8 '13 at 2:27

    @hedgehog1029 I agree with kotekzot, please don't make things up. – user91193 Oct 20 '15 at 6:37

Very simply: If you want to have either Crimson or Corruption, look for the text during world generation that says "Making World Bloody".

If you see this, you've got a world with Crimson, not Corruption, and can quickly choose whether to keep or discard this world.

Similar text clues might also hint at what special features your world will contain, but beyond that, if you want to just 'get' what you're after, you'd be better off just looking for and downloading a world file that meets your needs.

EDIT: As of 1.3, you can tell if the world is corruption or crimson by looking at the texture of the loading bar.

  • You ahould edit this for 1.3... – user91193 Oct 20 '15 at 6:38
  • @Gamer3001 I should...but I haven't actually played 1.3, so I don't know anything about it. You can suggest and edit if you'd like, or if you feel the difference is significant enough to warrant a second answer, answer it yourself and reap the rep. – Zibbobz Oct 20 '15 at 13:20
  • The loading screen just gets a special texture change depending on weather the world is corruption or crimson... – user91193 Oct 21 '15 at 5:49
  • This is one feature. What about ores, unique cavern monsters or dungeon brick color? – Tomáš Zato - Reinstate Monica Jun 30 '16 at 13:58
