    posted a message on multi-thread, new rendering system, VOB, Flags, Throwing space at time
    Just dusted off my account to say this:

    This is my favorite update since I started playing in earlier alpha! I've got a beast of a PC, GTX 770 etc, cost ~£1000, and yet minecraft refused to hit more than 30 FPS if I was lucky. Maybe it's my weak CPU or something, idk, but with this update, I've had a framerate increase of


    1217%!!



    So, I'm pretty happy! Back to attempting to make redstone computers :D

    Edit:



    Quote from ElectrixMC »

    Interesting that games like Battlefield, Portal, ect. can run fine on computers that get 20 frames. I always thought that was the main reason Minecraft lagged so much. Why is it so CPU intensive?





    As a general rule, games with randomly generated terrains etc have a MUCH harder job (Esp. CPU wise) than games like Battlefield. The reason is, for example: If you were to have a map in battlefield, that map would (Barely) change. This means they can do optimizations like combining meshes, baking (That is, saving the lighting state) the lights, and placing pathfinding meshes (So, entities don't need to use up a large chunk of time trying to path find, they use the paths that are already available)

    posted a message on Small 16 byte chainable RAM
    Hello again minecraft forums, long time no see!

    I've made a RAM circuit. It's 72x25x64 blocks, and you can access 16 bits at a time.




    I/O:

    Read enable
    Write enable
    Chip enable
    Address[3]
    Inputs[16]

    Outputs[16]

    Because there is a chip enable line, it's able to very easily be chained together using a demultiplexer to get larger ammounts of memory. My question is - How good is this compared to the existing RAM that people have made for minecraft?

    When someone tries to connect to my multiplayer server I get a similar error about cryptographic libraries, and they cannot join.

    I'm a java developer, and I installed the "Java Cryptography Extension Unlimited Strength" files fairly recently, I think this might be something to do with it, but I can't see why minecraft wouldn't run with the unlocked cryptography files, and I shouldn't need to choose between programming, or playing games.

    Anyone know what's up?

    posted a message on I made 2B of RAM, a 4to16 decoder, and a 16b multiplexer - how to improve my circuits?
    Hey everyone

    I've recently got back into redstone, and I made a few circuits. Can they be made much smaller, or are they quite good?


    2 bytes of RAM (Addressable at 4 bits at a time)

    4 to 16 decoder

    16 bit multiplexer


    Any obvious improvements? On reflection, I could probably have saved on space with the RAM by not integrating the "Write if selected" and "Give output if selected" into the modules, but ah well, it made it simpler :)

    posted a message on Building my first computer - any good & what motherboard?
    Quote from Wolley74

    overkill CPU for a start, the i7s have no advantage what so ever in gaming, and its a newer Haswell based one so it will not OC remotely well, they generate far too much heat

    what would be your budget?


    I'm not willing to spend more than £900-£1000 on it :P

    And I would only be overclocking if the system starts to get slow, I'm pretty sure it's going to be fast anyway

    posted a message on Building my first computer - any good & what motherboard?
    Hey everyone. I have recently decided to build my own computer. I want it to be capable of playing all modern games on at least medium settings. Only problem is, I don't know much about the hardware side of computers, so I have a few questions:

    A: Will the components work together
    B: What motherboard to get (I want to be able to overclock)
    C: Whether to get a 650 or 750w PSU
    D: Will this run most modern games on decent settings
    E: Are any parts going to cause a bottleneck

    This is my build so far:

    CPU: Intel i7-4770k @ 3.40GHz
    GPU: GTX 760
    PSU: Seasonic M12II (650or 750w)
    Motherboard: ???
    RAM: 8GB DDR3 1600mhz
    SSD: 128GB
    HDD: 2TB
    Case: IN WIN BUC
    Fan: Frio

    dit: Maybe this motherboard http://www.asrock.com/mb/Intel/Z77%20Extreme4/

    posted a message on Why wont my server work on my PC?
    http://www.minecraft...server-support/

    First of all, is it too hard just to read the list of sections before you pick one? It's lazy to just pick one at random, and not clever, because you wont get the best support. Anyway, till the mods move this thread:

    Try disabling your firewall.
    Is the host PC wired in or wireless internet?
    Is your internet working?
    While running your server, go on http://www.yougetsig...ols/open-ports/ - type the port as "25565" assuming you kept it to the default, does it say all okay?

    Edit:

    Are your friends typing the right IP address?
    Can you get on your server on the host PC using the IP "localhost"?

    posted a message on Does the force of an explosion decrease linearly?
    Hey everyone

    I was wondering (And I couldn't find anything on google), does the force of an explosion decrease linearly?

    As in, would standing 1m away from an explosion be twice as forceful as standing 2m away? Just wondering, because grenades in videos seem to do a fair bit of damage to close by objects, but they barely affect objects a little bit away :L

    Quote from MaxJ2001

    How do you edit the score?? Just curious... I'm not gonna post 300+ WPM. It's pretty obvious anything over 200 was edited...

    In the forum code, or HTML, it says something like:
    http://img.10fastfingers.com/badge/1_wpm_score_AD.png
    The AD part is the number, you can change the letters around but anything past (I think) IV will cause it to wrap to 0 :P

    posted a message on C# - Do I use an int or a byte in this case?
    Quote from Nocte

    *snip*

    I've changed the ints to bytes, and the speed is just as fast, so thanks ^_^
    Also, the real tile class contains more variables, so I couldn't use an array of bytes :P
    Quote from Sillen

    Why not make an int enumeration of the types of blocks, and use a multidimensional array of the int enumerations. The position of the tile is defined in the array, and the type of the tile is the value in the array at the position. It's the optimal solution for efficiency.

    Well, I don't believe I can use an enum, because I read the tile types in at runtime from a file, but if I understand what you mean, I've done something pretty similar: each tile has a byte variable (Called type), and I have an array of BlockTemplates, and the type variable is used as an index to point to a variable on the array :P

    Okay, I'm too honest :( I got 63, but I reckon I could get more if I was typing proper sentances :P

    posted a message on C# - Do I use an int or a byte in this case?
    Hey everyone, I have a little programming question.
    I'm designing a game, if you wanna know, it's a hexagonal map strategy game :P

    In my game I have a Tile class which is basically this:

    class Tile
    {
    int type;
    int xPos;
    int yPos;
    }


    The thing is, there will never be more than 255 types of tile, so I could use a byte for that, and since my map is 255^2, the xPos and yPos variables never go above 255; so it seems silly to store these variables as 32 bit integers, especially when you consider that if my math is right, I will save 572kb of RAM
    (Int32 is 3 bytes larger, map is 255^2, each tile would have 3 ints or bytes, so 255^2 * 3 * 3 bits would be saved?)

    However I read around the subject, and it seems that computers work faster with 32 bit numbers, and I need to do quite a lot of calculations using the tiles positions, what I'm wondering is, shall I switch these numbers to bytes because it makes more sense, or eat up RAM and potentially have a speed boost?

    posted a message on Which book shall I buy to help me learn to use blender 2.6?
    Hey everyone

    I've been interested recently in 3D modelling with blender, and I wanted to start learning how to do it. I have read a few PDFs and seen a coupla videos, but I learn better when I can read it out of a book. The question is, which book would be best for blender 2.6 (Both books seem to be for 2.5, will this be a problem?)

    Blender For Dummies http://www.amazon.co.../ref=pd_sim_b_2

    Blender Foundations http://www.amazon.co..._text_y(It says it's for 2.6, but I believe it was an error, and it was actually written for 2.5, when 2.5 was still in beta)

    Anyone got and ideas?
