[1.12.2] How to make a reed-like block that can only stay/grow underwater?

[Korlimann]

Hey there guys!

 

I wanted to create a seaweed block that acts like reeds.

 

At first, I tried extending my BlockBaseSeaweed class by BlockReed, but I'm not really sure anymore, if that will work.

 

I overrided the canPlaceBlockAt-method to work only, if the block where the seaweed should get placed is a water-block.

But I'm still not sure about some things, that might cause problems.

I believe, I'll have to set the material for my seaweed to water, so that it won't get destroyed. Question is, will water "flow" through my block, or will the seaweed create an airbubble underwater? Or will this simply be an issue about the texture/model itself?

 

Since I can't set a material when I extend by BlockReed, would it be better if I only extended by Block and would reuse all of the methods from BlockReed?

 

Thanks!
