Hi,

I just accidentaly flooded a part of the map in magma, and behold, all the trees just stand in a pool of molten rock and just dont care. Some part of the map was set on fire, and the trees ignore this as well.

Is this normal ? And if yes, how could I make them burn ?

[NecroRebel]

This is normal. Magma only heats squares adjacent to itself to a fairly warm, but easily survivable, temperature. This is not enough to ignite wood, and even if it was trees might not ignite. I don't remember if trees are counted as being made of wood or if they're mostly indestructible like walls.

AFAIK there's no way to make them burn aside from memory hacking. Getting magma on the same tile as the tree might do it, but that would take memory hacking anyway, so yeah.

Forest fires are still a distant dream.

Couldnt I reduce the ignition point of wood to a fairly low number, just above the highest temperature reachable by normal weather ?

Assuming trees are made of wood, yes. Which they're not; I just tested it by using DFHack to put magma in the same tile as every tree and shrub on the map, and not a one of them was destroyed. If being in the same tile as magma is insufficient to set them alight or destroy them, nothing you do will be enough.

So are trees basically terrain that gets removed with an axe instead of a pick and can spawn randomly?

Pretty much, yeah. They can be ignited in adventure mode and with DFHack, but seemingly not in fort mode.

Ok, thanks guys... I have a lot of fire related stuff in my mod, and got a report that trees always survive. Thought I modded them fireproof by a weird chance. Seems that it is more or less supposed to be like that,  even if I'd like to change it if I could.
