Talk:Evil biomes

Background wall spread
Hi there! just got through a discussion over at Talk:Corruption regarding whether backwall blocks can spread corruption (or crimson as the case may be). The user in question was kinda-confident that walls could only corrupt other walls, and not foreground blocks (unclear whether that could invalidate housing), but didn't affirmatively know the answer, and wasn't about to add it to the actual page, so I thought I'd cross-reference it here in hopes someone with more code-knowledge/experience would be able to help. Thanks.208.89.33.43 16:07, 16 August 2019 (UTC)


 * I found this thread on the forums that confirms walls do not spread biomes. ;-)  In general, the forums are a good place to look for "dirty details", there's a lot of experienced players posting there.  --MentalMouse42 (talk) 04:46, 17 August 2019 (UTC)


 * Posting this here as well, just for the sake of completion: I have taken a look at the source code, and it appears walls are in fact capable of spreading, but only to other, natural purity walls. See Talk:Biome spread (let's not keep this going over three different talk pages). --Rye Greenwood (talk) 04:18, 18 August 2019 (UTC)
