So you want zombies to be able to fall in the water, but not to be able to get back out? If so, you might need to ask rot if he can do it, he made the zombies, so he probably knows more about their scripting than most people.I just realized; Shadow, you bumped a nearly month old topic.
I'm pretty sure if zombies were real, they could get out of water, especially if they were advanced enough to know when to jump over things, they will know not to drown.
I'm pretty sure he wants it as more of an npc for a rp or something.
How do you guys know so much about zombies? They aren't even real, they could be little undead bunnies that CAN drown. You don't know...
Since Zombies aren't real, you can interpret them anyway you want. I've seen fast zombies, slow zombies, smart zombies, dumb zombies, infection zombies, curse zombies, mutant zombies, and heck, I've even seen gun wielding zombies.
