Ok's so I have found out so far only a few things really, but more to come:
Water's= how many flow from the source, Doesnt count the source!!
East
1 waters travels 0? maybe a half space from the end of the cannon and it blows itself up. facing east "least powerful direction"
2 waters travels 15 spaces from the end of the cannon. facing east. (5 dynamite)
3 waters travels 30 spaces from the end of the cannon. facing east. (7 dynamite)
West
1 waters travels 6 spaces from the end of the cannon. facing west. (3 dynamite)
2 waters travels from 30 to 50 spaces from the end of the cannon. facing west. (5 dynamite)***
*** for some reason this travels different distances based on when you trip the last dynamite or perhaps if you leave the switch on or immediately turn it of once tripped.
to explain better the projectile travels _ spaces. Im doing east right now and building the cannons with the extra stuff above them or watever. I built mine out of obsidian but Im thinking now you dont have to because of the water. o well
hopes u like my science so far!
Me finks I sees a pattern!!! also I think this is pretty valuable info for attacks
