Gravity Cushion Blocks vs Fall Damage

[swillfly]

I am building an underground forest in a large chamber 50 blocks high and very wide to house a variety of trees. I have a horizontal platform running above all the trees.

I know that if I put water down below deep enough that it will cushion my terminal velocity and negate fall damage.

Can I use slime globs or eyeballs or some other block type to negate impact fall damage from that height?

I don't want to use alien juice or triple jump or mods. I want to just fall and have whatever block type soak up all the velocity.

Any ideas? Has anyone tested this?

Thx!

About 8 or more tiles deep of water should be able to stop it. Try decreasing from there to find the minimum. I don't think any blocks prevent fall damage if landed on.

I did some testing and took well over 100pts of damage with top tier armor falling from 50 blocks up.

Given that the vertical space required for most all trees is 50 blocks high:
Falling from a distance of 50 blocks high results in massive damage..
Unless 12 blocks of water is placed at ground level.

So, the trees require 50 blocks high, a catwalk/platform above the trees would need a minimum of 4 blocks high, and there needs to be at least 12 water cushioning blocks at "ground" level when falling from 50 blocks high to avoid any falling damage.

The trees require 1h x 2w blocks which I may decide to leave as "plantable islands" which I can hop upon after swimming. The only caveat is that when falling from the upper catwalk it's imperative to land in the water versus on a tree island - which would be catastrophic.

Depending upon how this works out I may just decide to cover all the ground -including where trees have been planted- with water and deal with slow swimming. The fall distance would be less if I incorporated water covering the ground and upward (instead of ground and downward) so less water blocks may be required. I'm going to test this to see if less water block height is required as the distance between block impact is different.

Eye blocks and slime globs did not cushion impact whatsoever. Damage was the same as if I had landed on asphalt.

**Update: So the choice is to either have trees in a swamp-like scenario (i.e. ground covered in water) or water areas between tree "islands". After testing I found some variance.

Falling from above tree height (50 blocks up) requires 10 blocks of water in a swamp scenario and 12 blocks of water in a tree island scenario to negate fall damage. It seems that the risk of hitting a tree island and the added build space required aren't worth it. It is an inconvenience and time consuming (unless aqua tech/boating) to swim to land once diving into the tree farm swamp but much more efficient use of building space.

Curiously, trees will grow underwater. I put down 10 blocks of water first and then placed a sapling. It's all grown up now. I wonder if they will grow at any depth underwater or if their max height must be in air... I'll have to try planting at the bottom of an ocean world.
