About Double Slabs

Allows vanilla and modded slabs to be combined and placed vertically

Double Slabs

For the longest time I've been mildly infuriated by Minecraft slabs. Why on earth can't we place different types of slabs on top of each other??!! It makes zero sense to me so that's why I created this mod.

Double slabs is all about improving the vanilla and modded slabs through minor tweaks to their behaviour.

Features

  • Mixed Double Slabs - Have you ever wanted to place two slabs of different slab types on top of each other?? Well now you can!
  • KleeSab like behaviour on Mixed Double Slabs (or two double slabs which are of the same type if the replace same type option is true). This means that slabs now break separately when mining a double slab and the speed of mining of the individual slab depends on which slab you are looking at and which tool you are using. For example: if you have a mixed oak slab and stone slab, trying to mine the oak slab with a pickaxe will be quite slow but mining the oak slab with an axe will be quicker and vice versa. This a survival mode feature only.
  • Vertical slabs (excluding 1.21 versions) - Simply hold sneak when holding a regular slab to place a vertical version! This also works with combining two vertical slabs including vertical slabs from Quark, just ensure you are not holding sneak to combine!
  • Mod Compatibility - both the mixed double slab and vertical slab feature works with many other mods. Some mods require additional work to be supported.

Can I use this in my modpack?

Of course! This is the main reason I made this mod!
