Tesla coils are already in so...
Of course C&C wasn't the reason we have Tesla in IC2 but I can't help but imagine. I always thought we need more defensive structures in IC2 and I liked the more strategic usage of Prism towers. And of course it would require a little more thought to impliment.
What are Prism towers?
For those who aren't aware, Prism Towers are an interesting form of active defense used in C&C games. Tesla coils are the simpler soviet point defenses wherein anything coming into range of it will be zapped repeatedly with electricity until dead. Prism towers are somewhat weaker than tesla coils on their own, but they have the wonderful ability to 'daisy chain' through each other. So instead of simply being attacked by one tower, the target is simultaneously attacked by several towers instantly, as long as they're within range of each other, multiplying the power of the attack. This gives big bonuses to players who keep all the prism towers defending their base within range of each other.
How would they be implemented in IC2?
I'm guessing that scripting them wouldn't be too hard, using euclidean math to determine the distance between them to see whether they would chain. Attacks could be a standard light beam. They'd of course need to be wired for power. Maybe they would be half as powerful as Tesla initially, at 2/3 the power requirements. But that would of course be negated by the ability to chain attacks through multiple towers yielding greater defensive strength of your perimeter. They would have to be scripted to sync up, since a tower that has chained it's attack into another tower in the network can't itself attack again until it recharges. This might require some sort of priority targeting system so the tower with the closest hostile would be the one to get the combined attack from the group, or it would only chain to another tower if it didn't have a hostile within range of itself.
The biggest problem right now is that Tesla is already extremely powerful, cheap to build and easy to implement. I was always a fan of good planning with higher complexity systems yielding greater results though. :3 Maybe this system could be 'smarter', able to be set to target certain things and exclude the player?
What do yall think? I love using IC2 for base defenses, and I miss the forcefield immensely. Maybe... a suppression field generator to prevent spawning of monsters in an area...
