It's not really clear what this does, I think it makes stuff that's permanently destroyed when it's exploded and has persistent health (shoot a brick enough and it goes away) but I'm not sure. I haven't downloaded it since I don't even know exactly what it does. Please make it clearer what the purpose of this is.
1) prop tool and prop hammer
2) add props to the prop tool using /addprop [name].
3) get a prop tool and plant a prop, which is destructible in or out of a minigame.
your bricks will still be your bricks - they won't be destructible
destroyed prop bricks are actually killed
props are loaded from the "config/props and placement" folder, which is where the mod checks when you add a prop. think of it like a savedup/loaddup function, the difference being its made for DM.
if you want to convert entire builds, the propify wand will do that - it functions like the duplorcator except it just converts the bricks to prop bricks.
