Can anyone help me to deny water to mix with lava to make obsidian?

on block form:
    event-block is obsidian
    cancel event

Perhaps something like this?

I believe you were on the right track; however, getBlock() will return the block before the transformation. If we wait a tick, we can use the location of the getBlock() to get the new block.

on load:
    import "org.bukkit.event.block.BlockFormEvent"

on "org.bukkit.event.block.BlockFormEvent" with priority 5:
    wait 1 tick
    broadcast "%block at block at location of event.getBlock()%"

This should return cobblestone when water and lava meet.

So you can do something like this:

on load:
    import "org.bukkit.event.block.BlockFormEvent"

on "org.bukkit.event.block.BlockFormEvent" with priority 5:
    wait 1 tick
    block at event.getBlock() is cobblestone
    chance of 100%:
        set block at event.getBlock() to emerald ore

[doublepost=1501186991][/doublepost]It should also be know, during my testing, I believe the "on form" event is not broken- rather, it no longer supports an "of %blocktype%" argument. I say this because this also works:

on block form:
    event-block is cobblestone
    wait 1 ticks
    chance of 100%:
        set block at event-block to emerald ore

After testing the 'on block form' event for another forum post, I found that using the suffix "of %blocktype%" doesn't work. This may be an issue I was having, and I encourage OP to try the code himself.
