I am trying to build a puzzle map for some of my friends and having an issue with making floating grass/flowers with command blocks.
I can easily place 1 standing on its own ( https://i.stack.imgur.com/eGtjq.png ) (Using /setblock ~ ~2 ~ minecraft:tallgrass 2)
But whenever i use /setblock or /fill to create a line of these, it just makes the whole thing collapse. Is there any way for me to create something like this (https://i.stack.imgur.com/EWCmM.png) in 1.12.2 with command blocks? Thank you o/
