My base isn't in the water but it does touch it. I believe they fixed the zombie ai water glitch in alpha 5 but I may be wrong. Zombies aren't much of a problem any more but food is becoming a massive one. I can survive maybe another 5 days but I can't figure out how to farm. I ran out of potato seeds trying. Every time it glitches and the potatoes disappear. I place dirt next to water and then till the dirt, then I place the seeds. After about 2-20 seconds the seed just vanishes. Any help?
I just started my first farming and I had difficulty at first but now I got the hang of it.
For my fields I walled off a small 6x5 area of dirt with 2 block high log cabin wood blocks, placed a ladder on one side and put up some torches so zombies dont spawn inside. For my first field I dug a small trench inside and dumped water in it but I really dont think you need water based on my newest field which I skipped the water trench part.
I think the trick is, have the hoe in one quick slot, seeds in another, and do your jobs alternating instead of tilling everything then planting everything next. Till one tile by right clicking on the ground with the hoe equipped, and right click a couple of times (dont worry using a hoe for tilling doesnt damage condition unless you swing at things with it) You want to make sure you see a light grayish brown area with a darker brown spot in the middle - that darker brown spot is the spot you need to plant your seed. Equip the seed and right click at the center of the brown spot and you should be good to go.
Now never walk over that spot again or you will destroy your plant. This is also why I wall it off so zombies or animals dont walk over it either because they can destroy it too.
[EDIT] should also add, it may sound like a 6x5 area is pretty small garden, but that's really plenty of space especially for one crop (I have separate walled gardens for each crop). The reason is you can go every day to harvest plants (they mature at different rates so dont expect to come at one time and harvest everything at same time). And on top of that, once a plant is set you never have to replant it again unless you destroy it by walking over it. Harvesting plant puts food in your inventory and resets the plant back to seedling. Venison stew BTW is the best bang for your buck food - it requires 1 corn, 1 potato, 1 venison meat and 1 bottled water and it refills your food & water bars by like 75%!
