So, I caved in a couple days ago and purchased Minecraft. Although I still have a few questions (which I hope can be answered), it is quite fun.
The first time I started it up, I spawned on a small island with one tree; the only things within view were another small island with a tree and endless sea in every direction. I could not find coal and had to spend my night on the highest point of the second island (not very high), ever vigilent for monsters. I saw a couple of what I now know as Endermen, and when night was nearly up, one wandered too close and I kept my eye on it. I was dead then and there. I said, "Eff this," and generated a new map, which happens to have a jungle biome, sea, desert, village, mountains, forests, and even a winter area all within a small walking distance.
I have a lot of exploring to do and a lot to learn, but I have made my hideout high up on the steep part of a mountain, mined my way back and down until I hit the other side, then began to repeat the process down toward the first entrance. As a result, I encountered a gigantic dark chasm in the mountain, host to all sorts of monsters. I am trying to figure out how to go down it since it is very deep and pretty much a straight dropoff.
Anyway, now for questions, since I am not very tech savvy. If I were to create a map on, say, my laptop, would there be any way I could access that file through my home computer? I mostly ask for a reason which leads to my next question. The past two days or so, I have been playing Minecraft without issue on my laptop, but when I attempted to play today, the game had indescribably severe lag, rendering it unplayable. I tried shutting down and restarting my computer and restarting the program with no luck. My next question is, does Minecraft get like that sometimes or is something perhaps wrong with my computer?
I would really appreciate it if someone could help me out with this.
