Forbid starting fires on water tiles

[Night-Pryanik]

Summary

Bugfixes "Forbid starting fires (using firestarters) on water tiles"

Purpose of change

• Closes Water does not put out fire #59066. Since I can't confirm If you start fire in water no matter shallow or deep - it will burn and cannot be extinguished statement from that issue on latest experimental as of 22 October 2024, I suppose not allowing to start a fire with help of firestarters on water tile is enough to close the issue.

Describe the solution

Forbid starting fires (using firestarters) on water tiles. Also added a separate message for trying to start a fire on water.

Describe alternatives you've considered

Also forbid creating fire fields on water tiles through other means, for example flamethrowers, molotovs and magic?

Testing

Got a lighter and some splintered wood. Put the wood on tiles with shallow and deep water. Tried to light a fire on those tiles.

Additional context

None.

This is out of scope here but given the fact #76366 made liquid tiles configurable it might make sense to have a flag like NO_FIRE in the future as there are liquids other than water that would inhibit fires.

[Night-Pryanik]

Yes, good idea.

Is lighting a boat on fire handled separately?

[Night-Pryanik]

@Psithief sorry for not answering for so long, I missed your question somehow.

In my testing I temporarily allowed starting a fire on a boat, and it seems that fire is started not on a boat, but rather underneath it, i.e. on the water itself. This is confirmed by lighting a fire on a boat and then moving the boat several tiles away - the fire won't move with the boat, it will stay on the water tile. This is a problem much alike #21283 was a problem years ago.

But even if you're planning to stay in place and don't move, fire doesn't behave as it should. It doesn't break boat parts, it doesn't eat up fuel, it slowly dies out. All in all, at the moment "fire in boat" situation is rather problematic to be allowed as is. I think we can/should open an issue regarding this stuff prior to allow starting fires in water vehicles.
