This suggestion is that when modules are completely destroyed, instead of disappearing, they fall off the airship (or building) and crash into the ground as rubble.
Other airships wouldn't interact with the falling rubble at all, which would be in the background.
If the rubble falls on a building, it could land on the top and the building would take damage...
...Or, the rubble could fall through the background for buildings too.
However, I think the rubble should destroy ground blocks when it lands. But not ground blocks under buildings.
The rubble would continue burning when it hit the ground, but gradually the fire would get less intense and disappear.
Rubble on ground would stay there for the rest of the battle, just looking awesome.
This suggestion would mean that when a ship is entirely destroyed, it would leave a burning wreckage behind instead of simply vanishing. I think it would look nicer.
Sounds good, though why not make the wreckage interact with ships... :D
It seemed silly to me that in an airship battle, all the airships would line up over each other so neatly that falling debris crash down right on top of them. I also feared that it would be annoying.
However, when decks get added, it would be pretty cool for flaming debris to crash down, blocking a path for crewmen as they try to jump out of they way. Maybe there could be a certain chance that it would interact with airships? Though I don't really like the idea of that relying on chance. Maybe if an airship is a certain radius close to the other ship, debris can land on it?
Anyways, I thought of another mechanic for rubble to make it look better. Instead of just falling down, it flies back in the direction it was shot from, and rotates slowly in the air. (Maybe if the ship is facing right, clockwise if the module was right of center, and counter-clockwise if it was left of center? Might be too complicated though.) The more powerful the weapon that destroyed it, the further it would fly back, and the faster it would spin. (So if it was destroyed by a rifle, it might just drop without flying back.)
Also, when modules are destroyed, there could be an explosion effect, but that might be too much.
What do you think?
