World Seed



The World Seed feature enables the display of the random seed used to generate a Terraria world, and allows the user to input a custom seed manually when generating a new world. This feature is experimental, and requires that  is set to "true" in the config.json settings.

Worlds generated with Terraria 1.3.4 and later will always have a seed regardless of settings; The experimental feature setting merely allows the user to see, copy, and input them. If a seed is not entered manually during world generation, a seed is automatically generated randomly. Worlds generated prior to 1.3.4 will never have a viewable seed: while they were generated with a random seed, that information was only used during world creation, and was not stored in the world file.

When Seeds are enabled, worlds with a seed display a small seed icon in the world list, allowing the user to see that world's seed and copy it to their computer's clipboard. A copied seed can then be input when generating a new world, which results in a nearly identical generated world, provided it is generated with identical parameters (same size, same choice between Corruption and Crimson, and same choice between Normal and Expert).

Trivia

 * Entering the seed 5162020 creates a world with both corruption and crimson with several additional items such as the moon lords legs and a red potion
