Sand Fix

Picture this: you are wandering through a desert. Your hunger bar is almost empty but you have some wheat in your inventory, so you
place down your crafting table to prepare yourself some delicious bread... and then BAM! A huge chasm opens below your feet: it's Satan himself dragging you straight to Hell! You fall in lava and die, losing all of your items.

If you have found yourself in a similar situation (minus the Satan part, I guess) then this mod might be what you are looking for!

How it works

(mod demonstration)

Sand Fix makes sand, gravel, and their variants not react to block updates coming from above or from the sides. Other blocks that can fall are left unfixed to avoid potentially breaking some redstone contraptions or advanced technical stuff.
This mod does not fix sand/gravel generating mid-air without blocks below it.

Mod compatibility

Mods that implement blocks that can fall in the same way Minecraft does should have their blocks fixed by default unless said blocks have the "concrete_powder" or "anvil" block tags. If you are a mod develeper and want your blocks to work with this mod you can assign them the "has_sand_fix_prioritized" or "no_sand_fix" block tag to define whether they have the fix or not. If a block ends up having both tags, the "has_sand_fix_prioritized" tag will prevail, as the name might suggest.

Notes

It has been only a few days since I made my first mod, so you can expect the same (lack of) code quality in this one.
