I sense great sarcasm in this thread...
Ok, since I can't code for my life, let me at least try to help out somewhat with stats/use and stuff like that.
First of all, the ballistae should require roughly the same amount of materials as a catapult. Personally I say it should be slightly more, but this is up to the Balancing team.
Secondly, the ballistae should have three (3) adjustments on it. Angle up/down, turn right/left and "pull". I am not sure if the balistae should be moveable or stationary. Personally I say stationary.
Thirdly, the balistae should fire in a pretty straight line. Of course with some gravity drop, but not like the catapult which shoots in an arc. Think of balistae as a cannon and the catapult as a mortar.
Fourthly, the ballistae should do the same "damage" as the catapult but should NOT make buildings "collapse". Also, while it makes sense, the balistae should NOT deal damage to breakable object like doors/gates etc. This is because it would probably 1-shot them.
Finally, the balistae should have less range and health than a catapult. The balistae should be a anti-siege equipment weapon and not a trololol stand far away and kill all defenders. So even with less range, because of the walls it would have enough range to hit the catapults and siege towers. It should also have less health so that when an enemy get's close it's pretty much destroyed (unless there's a lot of people there to gank any would be saboteurs).
Hope this helps!
...and castle defence need multi rock thrower whell less catapults. Castle wars not fun, attackers always win, its too easy.
Actually that would be really fun. Some kind of "rock basket" or something where you could always spawn stones to throw at the enemy. Or a stone container thingie which you can tip and lose a hail of stones on people close to the wall. Kinda like in Stronghold :D
chadz, I know you like Stronghold. Make this more like Stronghold :D
Sorry if I seem demanding. I just would like stuff like this a lot. Don't be mad.
