How can I make a non-explosive dimension

[stark willow]

I want to make a dimension where you can’t break non-player placed blocks with explosions, but you can break player placed blocks with them. Any idea on how I can do this?

You'll need some way to track which is which. I don't know what's the most performant, but it probably won't be very performant on explosives in any case.

Chunk attachment maybe?

Do you think it’d be better performance wise if only certain blocks are un explodeable in that dimension?

Specifically the structure in it

It’s meant for a practice PvP thing where you can go to certain dimensions to have different terrain

I'm not sure, you'd still have to do another check for each block. It might not be a big deal though.

Also, sounds like fantasy might be helpful

I would mixin explosion and return an empty list for the effected positions in that din

but you can break player placed blocks with them

Ah

Oops

Yeah, then you need to keep track of which blocks a player placed
