Reappearing Walls

You can configure walls to respawn after a certain amount of in-game time.
Using the Staff of Illusion, Shift + Right Click on an illusory wall to edit its properties.
In the configuration screen, tick the "Respawn" checkbox to enable respawning for that wall.
You can also configure an individual cooldown that should pass before the wall respawns.
If you want to choose another time unit, just click on the unit button.

Editing the properties of an Illusory Wall

If you Shift + Right Click into the air or on a non-illusory block, you can also edit your default settings for new illusory walls you create.

📁Installation

If you want to setup multiplayer server, install both mods on the server too.
