chaining

Never existed.

aka Tesla from red alert 2... I like this idea :)

A claw that shoots another claw, but both are lightning

Off topic, but I wonder how OP a tremor that shot tremors would be.
EDIT: assuming you are running it on a planet-sized computer so lag would not be an issue

quote: Hmmm. You'd need to implement a minimum range for a weapon. Have a mine that spawns from a weapon hit, lasts for very little time (perhaps a single frame), and fires another weapon at a nearby target. The minimum range prevents a "chain" from hitting the same target again.

You still have to do something about collision detection though; a weapon fired from inside some hostile unit is going to hit that same unit.

I think it might be easier to just do it with lua. use Script.SetWatchWeapon and addon.ProjectileDestroyed to detect when the projectile hits something, then use Spring.GetUnitNearestEnemy and Spring.GetUnitPosition to find if and where to chain to, then rinse and repeat.

This also get around the problem of the lighning chaining between 2 targets constantly, but has the problem of having the drawn the lighting effect, which might be problematic.

of course, theres plenty of spots in this where it could screw up and turn the chaining weapon into a cheeseburger with ham.

That could be addressed by the weapon being penetrating (like gauss) while also limiting the range according to target (like starlight relay). Damage could either be singlehit on collision, or burnblow on explosion.
