Read this topic on increasing the amount of RAM available to Minecraft: http://www.minecraft...-for-minecraft/

thank you that help a lot!

I'm working on my Survival games map for the Planet Minecraft contest(http://www.planetmin...al-games-arena/), and I made my map on a miners dream super flat world (its underground). I decided that I want people to be able to go above ground as well to provide space for more chests as I don't have 200 as required by the contest (I only have like 150 or so). I also want to get rid of some of the chest in the caves because its chest heavy. So I decided to copy and paste it into a normal world so I can terraform the world, but my map is too big and when I try to copy it I get this error "java.lang.OutOfMemoryError: Java heap space" I cant take any more blocks off of the area I'm copying, and I think I just need to raise the heap space, any one know how I can do that?

I am new to Lua and computer craft. I've learned some stuff from seth bling's programming tutorial, and have written a few basic programs, but I am constrained by the lack of functions I know (I believe they are called functions, I am talking about things like redstone.setOutput, print, and sleep). So I was hoping that those who are lua gods and probably have them all memorized to help by forming a list here.

there is one function that I really want to know about, I need a function that acts like the redprobe program that tells if a specific side of the computer is powered

BEFORE POSTING make sure that you read the posts to see if any of the functions you are about to post have already been posted. these also have to work in COMPUTER CRAFT

Try the above version and see if it works.

thanks! its working so far

This is weird. So I installed this (1.4.6 version, because I already had it downloaded) and i was running the 1.4.7 prerelease.jar. It was working fine, until I lagged my game out with tnt (the brush tool places a lot of blocks... lol) and when I logged on the wand and brush stopped working, so I made new ones and they didn't ether. so I re-installed it, still didn't work. I then gave up. I just went on my minecraft and everything didn't work, when i did /help it showed the vanilla help screen. I just re-installed it and now its just the wand and brush as far as I can tell don't work.

thanks for trying to help!

So I was modding my game and it was working fine when I stopped. the next time I loged on and opened a world it crashed. i tried joining a server and it crashed, so I tried reinstalling mods. did the same thing. i had a fresh .jar that i had used to make the moded copy, so I tried that. didn't work. tried geting force update. still didn't work. even tried a brand new minecraft folder. still crashed. I have no idea what is going on. I have looked at the help section of the mojang website to no avale, and have run out of options.

Mods I was using when it started to crash (all but 1 was updated but one still worked even though it was 1.4.4):
timber(1.4.4)
modloader(1.4.5)
death chest(1.4.5)
Biosphere(1.4.5)
elemental arrows(1.4.5)
too many items(1.4.5)

Rei's minimap(1.4.5)

Ugh, how will I ever terraform the land for the pmc building contest http://www.planetmin...project-contest

I know! I want to build a roughly 88X44X220 block structure that will take like 3 days to make on its own, and i have to make room for it on that island. I've started to make it by hand, but it sucks doing that!

I am a relatively new member to the minecraft community, but ever sense I started playing in version 1.0.0 I have always been fascinated by red stone. Because of this I have been spending most of my time looking at, and building replicas of other peoples red stone contraptions to understand the properties of red stone, and I feel that I am capable of designing and building my own red stone contraptions, BUT I need ideas!






Here is a simple red stone devise I made : http://www.planetmin.../party-machine/






As I build devises I will post pictures and info here:

I have been having trouble with the installer. when i click install mods is says fatel error, and in the log this what it says "Catalogging local mods

can you help?

Will this work with the newest version (1.2.5)?

Quote from LtdSupply

I really like this mod. I'm doing a playthrough now and it occurred to me that Bone Meal should turn a few dirt blocks into grass blocks, maybe add a rare drop chance of a sapling from wood. I love the survival feel of it, but I'd also like to be able to thrive I think it'd be cool to be able to rebuild a civilization from scratch this way. In any case, awesome mod

Quote from steelfeathers

I don't think you should get rid of grass completely-- maybe put in a tiny oasis every so often that has leaves, a few blocks of grass, and a single reed/flower/pumpkin. That way, those things could be hard to come by while still actually existing in-game. It's impossible to get wool without sheep, or restore your health without pigs or bread (since there are no seeds). And besides, people might have fun trying to 'regrow' the world from the single sapling and block of grass they find

I think that grass should not grow back naturally from a oasis, but if you bone meal the dirt next to it it would spread a little bit and after you used bone meal to spread grass over a large enough area it would start to grow on its own.
