How can I protect a selected area against TnT in Minecraft?

I want to create a Tnt scene, that's why I built a green screen around it. But I don't want the green screen to be damaged in the explosion (the green screen is made of wool)

Can someone help me?

Why don't you use textured obsidian

I could also pack you up quickly

Simply place barrier blocks in front of your green screen as an invisible protective wall.

It works with the https://dev.bukkit.org/...worldguard plugin

Or

You write in a command block that is executed:

/ fill x1 y1 z1 x2 y2 z2 air replace tnt

So that all TNT in the range of x1 y1 z1 and x2 y2 z2 are removed.

You could put a command block on Repeat that repositions the wool again and again as soon as it breaks

But better take this green tone than green screen
