Im CactusRomain26 or TrainPlaneFR in Minecraft Bedrock !

Commands

Go in a flat world.
type "/fill -20 0 -20 20 0 20 deny" to create platform base, "deny" means that players can't mine blocks over this block.
next, type "/fill -20 1 -20 20 1 20 [your choice's block (like grass_block or oak_log)]" to create the floor of the skygen.
type "/give @s border_block" and surround the skygen. People in Survival or in "Member" rank can't go out of this block.

Now for the generators :

type "/give @s repeating_command_block" and put it on the floor of the skygen. Remove the "deny" blocks under !
put "always active" in it and type "/setblock ~ ~1 ~ oak_log" for an oak log. It will spawns over it and when you mine it, it regenerates.
