BlockSpreadEvent does not get executed when fire spreads.

[KillerCreeper112]

Expected behavior

When fire spreads, BlockSpreadEvent should get executed.

Observed/Actual behavior

BlockSpreadEvent does not get executed when fire spreads.

Steps/models to reproduce

Register event:

   @EventHandler
    public void onBlockSpread(BlockSpreadEvent event) {
        Bukkit.broadcast(Component.text(event.getBlock().getType() + ""));
    }

Place down blocks like planks that are burnable. Set fire to the burnable blocks and observe as the fire spreads with no message being printed.

Other

The docs do specifically have fire spreading as an example: https://jd.papermc.io/paper/1.20/org/bukkit/event/block/BlockSpreadEvent.html

I guess if this is intended behavior, this issue would only be a "misleading doc issue" as BlockIgniteEvent seems to work as an alternative method to check for fire spreading.

In my testing, I see BlockSpreadEvent being fired for it, as well as BlockBurnEvent. BlockSpreadEvent is fired when a fire block is going to be created in a previously empty block. But that isn't all that happens for fire, BlockBurnEvent is fired when a block is immediately replaced with a fire block.

Would we want a BlockSpreadEvent to be fired when a block is immediately replaced with fire? Otherwise this can probably be closed

That just sounds like it'll get confusing when both events need to / can be handled
