I'm currently looking at the "Minecraft Escape" project from Palette and GLP and would now like to create a world border that enlarges every evening (as in "Minecraft Escape"). Can I somehow do this with a command?

Didn't you even show in a video what's in the cloud?

Yes, but what's that in there?

Try a command block and a daylight sensor that you only have to switch.
