Just a Tiny Mod #7 is here!
This one was pretty darn hard to make because of the very tricky mud generation (basically, when it rains/thunders, sometimes dirt/grass blocks will change into dirt, and when it's sunny, mud blocks turn into dirt if they're not in biomes such as swamplands, i also had to remember to reduce lag which was a very hard thing to do, while also having to code a part of the procedure because of int -> double variable conversion)
This mod adds a new block: the Mud block, which spawns near most of the water supplies (rivers, lakes etc.) and also normally in some rare cases or in the biomes listed here: Taiga, Swamplands, Extreme Hills, Ocean, Beach, River. You can craft a new block out of it and also smelt the mud into a mud brick which you can then craft into the Mud bricks, which are both useful for protection and decoration.
There's also a system mentioned before already; The Mud will turn into dirt blocks once it's not in the biomes it normally spawns in (excluding the rare patches). Meanwhile, when it's raining or thundering it will spread like grass blocks, to dirt and grass (on all biomes). Of course, you know the proces is reverseable. So, here's another use for rain (sometimes). I hope you enjoy, tell me if there any bugs.
JaTM means Just a Tiny Mod, it's a series of mods sometimes suggested on reddit or other media that just add some tiny things to Minecraft instead of super large system of things. The mods won't get updates unless there is a bugfix.
