[MC-204047] Lightning bolts still create fire when hitting a lightning rod

The picture says it all. Tested the lightning rod (placed it down and changed weather) and the fourth lightning that hit set the block next to it on fire.

Important instant Edit: This picture was recreated. In the Original situation I had a Block of TNT next to the Lightning Rod. The Lightning hit, TNT got ignited and the block on the Opposite site of the TNT, next to the rod, got ignited by fire. Since the TNT exploded I wasn't able to create a screenshot fast enough 😉

I'm unable to reproduce, fire is created every time a lightning strikes a lightning rod. However, note that the rain might put out the fire again pretty fast, and that it doesn't light all the blocks adjacent to the lightning rod on fire, so that if there aren't many blocks next to the lightning rod that can be set on fire, you won't see a fire as often.

@unknown I was able to reproduce. (Though to note the Lightning Rod activating the TNT is intended since the rod gives of a redstone pulse when activated)

I was able to catch this on video.

Though to note the Lightning Rod activating the TNT is intended since the rod gives of a redstone pulse when activated - that's correct and not the point of this bug report. I added since it could've been part of the problem, but as Kevin's video is showing, it clearly isnt.

I don't see this Resolved at any point violine1101!

I thought the lightning rod was intended, so that there can't be a fire outbreak? It could be that the fire spreads to a block near the rod and is protected from the rain from something like leaves an then the fire could spread. If the thunderstorm will end in that moment there would be no rain to put it out as well.

IMO this is a bug since the devs stated more or less: We dont want your house to be burned down by a lightning, so here is a lightning rod and if you install it, it won't happen.

If the fire would always put out by the rain, the problem would not have been there in the first place, so the devs would not have invented the rod?

So please reopen this bug report, or I might just need to write a new one, since this clearly can't come together the way it is right now.

Theree's also multiple proof of this situation in the latest ilmango video: https://www.youtube.com/watch?v=6-81_JCArlw

@Torben Mayer The point of the lightning rod isn't to prevent fire it's to redirect it away from your wooden buildings. To quote the changelog:

"Keep your builds safe (well, as long as the closest area around the lightning rod is fireproof) during thunderstorms!"

Brianna Walpole 2020-11-05T21:33:30Z

with this you probably would be safer without a lightning rod

Torben Mayer 2020-11-05T21:51:54Z

@Percy Walker ah okay. tbh I didn't read the patchnotes. I was just assuming, that I can put it on non-fireproof buildings to protect them. I think many others do so.

In that case, this isn't a bug, but most certainly everyone seems to expect the lightning rod to prevent fire completely and not only when there are fireproof blocks next to it. So this might just be an idea on how to improve the rod. When I see some cities and builds, its hard to integrate a fire proof place for the rod every x blocks into the building, without changing the look of it too much.

@slicedlime Works as intended ... in this case I have to agree with Brianna's comment above, your buildings would probably be less likely to catch on fire without using a lightning rod. Lightning rods would actually specifically set your roof on fire instead of lightning hitting in a completely random place. I doubt that's their intended purpose. Wheren't they meant to "prevent" fires?

Torben Mayer 2020-11-11T13:20:26Z

@_zombiehunter

Nah, for this specific bug report I also have to switch sides. It works as intended, but no as expected. The patchnotes state it pretty clear, as Percy Walker already said.

For everything interested, there is already an idea submitted in the feedback area that you might want to vote for.

Each cube is 1 cubic meter, would a lightning bolt put fire in the wood if 1 meter away from it?

pancracio 2021-01-28T19:38:04Z

This is not a problem of the lightning rod, lightnings have a effect area (aprox 4 blocks) so you need to put it in inflammable blocks

Todd Halfpenny 2021-02-01T10:56:08Z

I guess confusion comes from images like on this post, where a Lightning Rod is placed on a wooden roof.

DarkstalkerMoon 2021-08-27T12:01:49Z

Ah yes. A lightning rod that burns more builds than it protects. Excellent idea mojang. TOTALLY a good idea.

fr how was this marked as worked as intended its obviously a bug.

user-f2760 2021-08-27T12:03:32Z

Then don't put it on your builds, but near your builds; the only thing the rod does it attract the lightning, not change it in any way; that's how it was designed.
