I think I solved it!

I found a thread on reddit from 2 years ago: https://www.reddit.com/r/Minecraft/comments/34bxus/installing_forge_with_the_new_local_java_runtime/

I followed his instructions about the console commands and it worked. Forge is installed now and I could follow the rest of @paintbrush11's explanations!

I share this for those who also have a local jre and didn't solve the issue yet.

And once again: Thank you!

I must have been aiming wrong, because I hurt the villager when I tried to hit the cart. And I didn't want the villager to die by a second stroke, so I asked. But it was indeed so easy!

And now, thanks to all of your help, my village has come to live! Already at 5 villagers now (starting from 2) and, boy, what a feeling when they first entered a house to stay the night! As if they were saying: "Good job, mate. This is a house I love to spend my life in." Okay, what they really said was: "Hmm". But I could really feel what it meant...

Inside my brain:

"That's lava. Stay away from lava. You just managed a level 30 enchant on a diamond pickaxe. And remember the 4 ender pearls you finally managed to gather. Also, you just digged for diamonds, you know how rare they are. And you forgot to take the water bucket with you. So stay away from lava."

"Ok, but it's just one hole to fill and the lava's gone. I'm sure I can reach it. Really. Just need to step a little closer to the lava. Closer. Careful. A tiny bit clos...aaah..."

As someone who started with minecraft 1 day before 1.9 came out (and playing survival on normal), these are my thoughts:

1) Whenever I fight skeletons, using my shield and so effectively making their ranged attack useless, I wonder how unfair a fight against them must have been before, without shields. They might have been the toughest mobs? The way it is in 1.9 feels somehow right.

2) Two strikes with a sword or one with a bow to kill zombies isn't really time consuming. I found myself often just standing there in the night to kill dozens of them just because it is quick and easy. Even 5 or 6 attacking at the same time are easily controlled. That might have been even easier before (I guess), but this also feels somehow right.

3) I don't understand how this "negatively impacts mining"? You don't mine with your sword or bow, do you?

Hi,

just now the launcher downloaded an update and can't start 1.9 anymore. I played for days now version 1.9, so I have no clue what has happened. This is the error message:

Fehler: Hauptklasse net.minecraft.client.main.Main konnte nicht gefunden oder geladen werden
Java HotSpot(TM) Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

The german part means Error: Main class net.minecraft.client.main.Main couldn't be found or loaded

Additional info: I'm a new player and so my install includes a local Java in the minecraft folder, instead of a system-wide Java install. I want it to keep that way.

Does this paragraph mean, it is generally better to put on the cheaper enchantments first? I always thought it would be better the other way round.

No, it means you want to keep the prior work penalty as balanced as possible.

Think of it as building a pyramid, start with the pickaxe and the original uncombined books at ground level.

When you combine 2 things the combined thing is one level higher then the highest of the 2 things that went into it.

And you want to keep the pyramid as low as possible because the prior work penalty on each level is double the previous plus one.

For instance the original Eff I books had a PWP of 0, the Eff II books should have PWP=1, Eff III PWP=3, EFF IV PWP=7 and the EFF V should have had a PWP=15 (the cost of combining them is higher because you also pay for the enchantments to be combined as well as the PWP.)

Adding that to a pickaxe gives it a PWP=31 as long as the PWP of the pickaxe isn't higher than 15 and adding another book brings the PWP up to 63 which is Too Expensive so no further combining can be done.

However, assuming the other books were pristine with a PWP=0, just to keep things simple, adding the other books to the pickaxe first would have given the pickaxe a PWP=7 (1 after the 1:st book, 3 after the second and 7 after the 3:rd), then adding the Eff V (with PWP=15) would bring the PWP up to 31 and it could still have something else added to it. (or an emergency repair on the anvil.)

--

This also means that when repairing stuff (if you don't have Mending on it) you should never repair it one diamond at a time because the PWP goes up every time, instead you should wear things down as far as you consider safe and do a full repair with 3 or 4 diamonds.

Could you have made a mistake at some point and wasted an anvil operation by, say, combining an Eff III book with an Eff II book?

That would have increased the prior work penalty since you would have then had to redo the combination with an Eff III book.

(Unless you discarded the "contaminated" Eff III and made a new one.)

Even if you had got your Eff V pickaxe for 20 XP levels you would only have been able to add one more book before it became too expensive.

Though combining the remaining books before adding the combined book to the pickaxe might have worked if the other books weren't also pieced together from level I books.

You really should go for higher level enchantments.

Even if they were combined with unnecessary enchantments, as long as they aren't ones you absolutely don't want, like Flame Aspect on a sword or Silk Touch when you want to add Fortune, though even that would work if you add the Fortune first.

Sure when combining the books the unnecessary enchantments would increase the cost but the prior work penalty increases exponentially with each anvil operation.

And enchanting the pickaxe on the enchanting table would also have saved you some anvil operations.

And, no, the state of the anvil has no effect on the cost.

--

Actually, assuming the other books weren't pieced together from level I books then, if the Eff V book hadn't for some reason been more expensive then it should have been, adding it last would probably have worked since the prior work penalty is affected by the book or tool that has the highest prior work penalty so changing what is combined with what can change the final cost.

I would say you're experiencing the prior work penalty https://minecraft.gamepedia.com/Anvil_mechanics#Prior_Work_penalty and having an issue with the number and method you used to combine books. For instance putting an efficiency 5 book on a brand new pick costs 5 exp levels BUT if you combine 16 efficiency 1 books to make an efficiency 5 book, THAT book would cost 20 exp levels to put on a brand new pick. I'm not sure what you're doing what caused an efficiency 5 book to cost 31 levels to apply as the first enchant unless another enchant is applying as well and/or you aren't a pickaxe that has been repaired before.

Dude, you've got yourself turned around. You don't need to mess with Java. There are multiple ways to install a mod, but the easiest and most common way is to use the Forge modloader.

Go to https://files.minecraftforge.net/ and pick out the Minecraft version the mod is for. Download it, and make sure that Minecraft is closed out when you run the installer or it won't work.

When it's done, you'll need to find the .minecraft folder. There are a few ways to do this. You can either go to your resource packs menu, click Open Resource Pack Folder, go up one folder layer, and put the mod file (your java file) in the new mods folder that Forge should have created. (Just make sure to exit Minecraft when you're done.) Or if you have a Windows device, you can also press the Windows key and R, then type %appdata% in the box that appears. Find the .minecraft folder, and again, put the mod in the mods folder. (If you have a Mac or Linux, google it. I don't know.)

Open up the Minecraft launcher and select the new Forge profile that's been made.(Click the green arrow to the right of the play button.) Enjoy your mods!

(Rarely you'll come across a mod that's a zip file or something. Works the same way.)

Also, make a new world to play with your mods in. Don't play a modded world in vanilla and vice versa. This can really screw up that world if you're not careful.

I haven't made a mod myself yet, but I think the reason you think you're having problems with is this: Minecraft for the PC does indeed run on Java. This is why the vast majority of mods are in Java. But because they aren't connected to Minecraft at the moment, they have no idea what to do.

It has to be skylight.

But you could get away with just one shaft if you place the doors right.

Nothing's really changed.

You still swing, swing, kill then move on with your life. If at 0.3 seconds longer at the most.

If you don't want to wait the full 0.6 seconds, time your attacks with the 0.5 seconds invincibility frames, it's still a really effective and fast way to kill things.

Thank you very much for this clear and straight forward answer. It helps me a lot more than all the reading about JVM!
My computer's hardware can be seen in the screenshot I have attached on my last reply to you. I am just wondering about the 500 MB setting, since it was so after installing Minecraft, whereas most people say that 1 GB would be the default.
Of course I don't expect wonders from my rather outdated processor and graphic card, but I was so used to games where you always see the landscape without seeing it build up. But now that I understand it is the way Minecraft works, I'm not worried anymore.
I do have a stable vsync'd 60 fps framerate (unless I'm farming skeletons for xp), and that's more important to me.

Sorry, I was looking up all I could find about JVM the last days. First day to have a look at the forums again is today.
There's a misunderstanding. Not my computer has 512 MB RAM, but Minecraft only allocates 512 MB. I used the JVM string in the profile editor to raise this, but it still is pretty slow building the landscape. However, I saw a Youtube video about Minecraft on a 64 GB RAM computer, with Minecraft allowed to allocate 40 GB. The landscape builds just as slow there as well. So maybe that is just how Minecraft works? Link to the video:

Unless you're running a server, an HD texture pack, shaders, very high view distance, and/or a bunch of mods you don't need more than 2GB of ram allocated to Java. In fact allocating to much ram can have a negative impact unless you have a custom java arguments script to help manage it properly.

If your PC is 64bit, absolutely make sure you only have 64 bit Java installed. Your processor and GPU can make a big difference on how well the game runs too. The chunks always tend to load visually a bit slow around you when you move fairly fast, especially so if the chunks are generating for the first time.

Oh, I didn't know your nationality, so I gave you the wrong link, but you're using it anyway, so it's all right. It's an invaluable resource.

http://minecraft.gamepedia.com/Drops

Equal distribution over the drop range (in this case 0-1), so a fifty percent chance of dropping a pearl (pearls are a common drop). Getting eight in a row that drop nothing is just luck (or lack thereof). Keep trying.

Edit: just read your response to Robadon and wanted to comment. That half-a-gig of RAM in your computer is what's causing errors such as you describe. When you try to load too much of the world at once, you can run out of free memory. I have 8gig in my computer, and the same thing happens to me sometimes. You can fiddle with the graphics settings (put them lower) and there's a mod called Optifine which is supposed to improve performance on lower-end systems. Your other option is to stay at home where you computer is comfortable, but that does get boring sometimes.

Hi all,

I probably do something wrong, so I didn't want to post this as an error message. At least not until you confirm.

I own Minecraft for a little over a month now. Which means, I know very little about it. But the following seems to be strange (I play on 1.9.2/vanilla in survival mode):

In my farm, which is underground, I have three stories. The first floor is for the cows, the second for the sheep and the third for the chicken.

No matter how many cows I have, if I play for a while (exploring, mining, whatever) without visiting the farm, for example 2 or 3 real world days, the number of cows is reduced to 5. Always. As if I'm not allowed to own more than 5 cows.

The sheep don't vanish, but instead always one of them is outside the farm and at least one other loses its color (becomes white).

The farm is secured several times. There's only one entrance, which is a wooden door. On the sheep floor I added another door (out of desparation), and both, cows and sheep are behind a fence on one side, else surrounded by stone. I use lots of glowstone lamps in the ceiling, but every story has 2 blocks spacing to the next one, so that no ceiling is ever the floor of a story. Just in case that matters.

I have made two screenshots, pictures often say more than words, but I'm not allowed to upload them.

What am I doing wrong with the animals? Or is it an issue of Minecraft?

Endermen confuse me. Is there a limit of ender perls one can get from them? Is there another source for the perls? I ask because the first enderman I killed dropped 4 perls (I think I had a luck enchanted weapon or tool), the next only 1 perl. Since then I killed another 8, and none of them dropped anything. It is hard enough to find enough endermen, since I don't have a spawner (only one for skeletons), but if there is a limit, how shall I find the stronghold with just 5 perls?
