Hi!

Can the flamethrower deal damage?

hi, that depends on your fire rules, and your specific need. flags can also override rules. also certain plugins can prevent fire from working properly, such as with Death Notes use of the OnFireBallSpread hook where it removes the player as the initiator.

you should configure the trace settings in the config and then use tpve.trace to see why damage is allowed or blocked. if it says Unknown Weapon then a plugin is removing the player as the initiator. otherwise you can take those entity names and add them to an entity group with your own rules. by default fire cannot harm anything unless its being allowed by another plugin.
