BlockIgniteEvent: How to get the block burning?

I just realized that getBlock() from the BlockIgniteEvent always returns air. But how to get the block that's burning? A simple BlockFace.DOWN isn't enough cause blocks can burn at their sides or at the bottom, too. Or do all blocks around that air block automatically burn, so I have to loop through all block faces (except NORTH_EAST and such) ?

//EDIT: BTW: I'm talking about the block that starts to burn, not the one that it spreaded from.

 

If there is a block below, that block will be burning, otherwise the adjacent blocks and one above will be burning. That's just a graphical thing, though. Those blocks don't have any sort of "burning" state, they just happen to be next to a fire block.

 

nisovin: I don't need a graphical thing. So I guess if there are more blocks connected to the fire block (the one that's air in the BlockIgniteEvent) every one of them is burning (meaning they can give a BlockBurnEvent without any other notice before) ?

 

You're asking about a graphical thing. The only block on fire is the actual fire block. The blocks next to it are just blocks. It may look like they're burning, but they aren't, they're just next to fire.
