If you want to make your world in Minecraft on Android, then use mod Floating Text +which will allow you to make stunning lettering. It’s great for map makers.
A mod called Floating Text + adds to Minecraft a new feature that will allow you to create such fancy lettering. They are opaque, but the hero can pass through them.
And you can place this anywhere. The function is very easy to use. Command to the console to write text.
And to remove the text in Minecraft Bedrock, enter this command into the console.
But to make the text like the bottom screenshot, you need one special utility. This is an .exe file – run, of course, only on a PC.
For convenience, the program is in the archive with fashion… Have a good game!
