Lava Heated Blocks (Minecraft)
I very recently begun making modifications to Minecraft. The very first thing I came up with was to make lava heat up blocks next to it. This went over well with people on Reddit, so much so that a YouTuber made a Spotlight about it. This makes me very happy.
Sadly, due to performance issues with my implementation, most people will be hard pressed to play with the modification during standard gameplay. I will possibly revisit the code some time in the future.
The download can be found under Minecraft Modifications.
