Very Basic Lava
#1
This is basically the water plugin slowed down, and with lava.

Once I've figured out how to detect what's burnable and set it on fire, and also damage the player, I'll make sure to do that. For now, it's just epic flowing lava that will be very dangerous when damage is added Wink

If anyone has any snippets to detect wood and things and make it work with this plugin, please let me know.

It doesn't flow Sad
It's the fire plugin, but with lava that acts like fire

Haha, I copy pasted the wrong one!!! :L
There we go, it should be fixed and flow now Smile the flow path is identical to water, but that's satisfactory as I actually prefer the way water flows in this server.
