hello,i have a question,how do i make fire burn blocks and tnt explode on mcgalaxy? i've already asked many peoples about this,but i got no good answer,some peoples said i needed to set the physics to instant,but that didnt work,if i can get this to work i would be happy,thanks for the attention!

Make a block burnable in the level you're in:

/os blockprops [block] lavakills
OR
/blockprops level [block] lavakills

Make a block burnable across all levels:
/blockprops global [block] lavakills

Make TNT explode:
/os physics 3
OR
/physics 3

Place tnt. Place fire on top of it.
OR
Use /c4

For more TNT types, try /search blocks TNT
Then use /[block]
to toggle that type of TNT placing

hmm... seems like only lava can burn that block,i want the block to be burnable by fire too.

It's a shared property. If lava burns it, so does fire, as long as physics are 3.
