Lava to obsidian creation event?

I was wondering if you can catch the event of lava being turned into obsidian by running water over it. Can't find anything about it in the javadocs.

 

BlockFromToEvent, I think its that event

 

You sure? The detailed description implies it's just for the event where a fluid flows from one block to another.

 

then it may be BlockPhysicsEvent

 

I'll have a look at it I guess, the description of that event isn't very informative though.

 

If your trying to stop the block from creating, I would just suggest if the two blocks are next two each other, change either the lava or water.

 

Maybe BlockFormEvent is what you are looking for.
