Coincidently, it's already doing just that. I'm not sure yet how we'll be handling the projectile / explosion / damage stuff. However, it does alternate between barrels when firing and the delay is currently set to 500ms.
It's pretty cool to see in action, and I can't wait for when we get it finished.
Haha,
great minds think alike I guess that's pretty much what you'd expect from a turret like this. Sounds like an amazing add-on, like you said, can't wait 'til it's finished.
As a suggestion for the projectile/explosion/damage stuff, I think the projectile should look somewhat like a scaled-down tank shell, sort of like a high-calibur artillery gun. For the explosion, personally I don't think it should be too big, seeing as you're firing two shots/sec, might get spammy if it's too large. Last but not least, for damage, I assume it's possible to script it so that if the projectile hits the player directly, it causes a significantly larger amount of damage than it would if the player was just caught in the AoE. Correct me if I'm wrong, but that is possible, no?
