Fragile Glass and Thin Ice is a Minecraft Forge mod which does the following things:
- Adds Fragile Glass (including stained and pane versions), made with sugar and water
- Adds Thin Ice which breaks underfoot unless stepped on carefully
- Adds Weak Stone (disabled by default) which crumbles into gravel on contact
- Adds configuration for practically any block (vanilla or any mod) so that it can break and/or have some other effect when collided with fast enough
- Adds configuration for how fast different entities have to be travelling to break a fragile block
Note: The author is only maintaining this mod for Minecraft 1.12.2 (bug fixes) and 1.14.4 (new features and bug fixes).
