Once again, lovely solution. :)

Also, I was wondering how I would host this "Website", as it needs a few bytes here and there for saving the shortened URLs.

Much obliged!

And then rounding 0.75 up would equal to one? Even if it's just more than 0.5?

Sorry for the abs, I had a negative number inside it like a few seconds ago.

15 / 20 = 0.75

Okay, so let's suppose everything is positive.
Why does (15) return as 0?

int Value = (int)Math.Ceiling((double)(Math.Abs(15) / 20));

:S

if (Number > 0)
{
Number = Math.Ceiling(Number );
}
else
{
Number = Math.Floor(Number );
}

-16 returns to 0?

-16 / 20 = -0.8?

Logic error? I just said I am suppose to get negative values. However when I hover over a negative value, the value returns positive. ::

I also have every block in the positive not in the negative, I convert the negative to positive with Math.Abs.

-- 5 / 1 = 5.
-- -5 / 1 = -5

Anyone else? :L

Interesting answer though. I tried it, and I feel like it's something like that causing the bug. Because whenever I select it on the left side(- side) it puts it on the right side but in the exact opposite way.

Well, I thought that as-well. But, the chunks have a cooardinate that be negative, however the blocks should be more than 0 and less then the size of the chunk.

Indeed, I flagged it and hope a Moderator will take care of it.

What?

Why don't you go ahead and loop through the items of the items you are looping through too? I mean, from this point of view, hiding a master item would make you unable to look at the subitems, right? Good work once again SA.

Edit: The error I am having is that whenever I click on a location or a chunk that has a minus cooardinate, it simply won't place the block correctly, however when these values are not in the minus, it does everything I want it to.

So I decided to check the Noise class, and there seems to be no problem there. It has to be the if statements, but there is absolutely nothing wrong with it.

"The conditional-AND operator"? Now here comes the best part, before I modified the nose points, it used to work fine.

It is an array with points, which should generate the level, however the value return from f / 10 is perfect, only it gets filled in like it's Chunk.ChunkHeight. Very odd.

I'm sorry. Here, I'll print it out:

Problem got resolved by a work around. Thanks everyone for the help!

1. Resolved that, issue stil exists.
2. Yes, as I said in my topic, I did it to see if that was the problem.

No thanks. Switches do not work.

I did that on purpose, because when I do not do it the error is still there. Thanks for your contribution though. :)

No luck, I'll post the full code though.

Oh, well, if it's less than zero it would just be stone. This might be a good thing to check however. Maybe I can change some of this code to that, because that seems to work.

So, let's assume I will make a variable:
public Chunk[] Chunks;

I could set it via:

public void ReloadChunks()
{
Chunks = new Chunk[9];
}

"ReloadChunks". Access is related to being static. Let's suppose you make a public integer, you can NOT access it via another thread.

Thanks a lot for your answer. The thing is, they should not be static as it's actually a void I used to use without a thread, but now it's a thread I can not access the variables.

I got it fixed. :P

I got it fixed, I'm sorry. I was using Point[] instead of ReturnPoint.

Thanks :)

Double arrays do not really have to be initialized, when they are declared they will all have the state of 0. And this is confusing because it is saying it's null. O.o

" // -- Strangly, this is the error.
ReturnPoints[i] = rd.Next(0, (int)Points[i - 1]);
"

Well, I am stuck because I need these points to be generated.

Very helpful, as always. Thanks! :)

Perfect, I after a few days of Googling never saw this one. :(
Thanks a lot!

Okay, whatever seems to be the problem it's not the random, I will do some research in my code, I thank you all for the help.

How unfortunate that it didn't. :L

Chunk.ChunkY is the cooardinate of the Chunk, this is a way for me to only generate below the walking level, it's a bit like Flatgrass in Minecraft really. Oh, yeh, I am, I always forget about the fact that everything starts at zero not at one, however, the fact that the chunks are being generated like this:

http://i48.tinypic.com/ws5h5e.png


Has nothing to do with any of that. :L

Also, the colors are pretty much squares (32*32), which all show another chunk. So, you can see that the blocks are not random and I don't understand why.

Oh yeah, also,

The different colors are the blocks in the chunks, as you can see there are three different chunks yet they all have the same block.

Funnily enough I already tried that, anyways, here is a picture to give you an idea what messes up:

http://i48.tinypic.com/ws5h5e.png

Yeah, I kinda wrote the question wrong. Well, I am just hoping I can get as many numbers as possible. Zoltan just answered it for me. :P

Yes, exactly, yeah it is, I'm not sure too. :P

Yes, I understand, that's why I am interested into calculating it as far as possible. I have no clue where to start though.

The line is:
return BitConverter.ToInt32(b, 0);

Yes I will, I only currently have a small problem, I hope you can make something out of this:

Client sends this:
public void UpdateBufferSize(int Size)
{
/* Create a byte array for an integer. */
byte[] ByteInt = Helper.ConvertIntToByteArray(Size);

/* Create a one byte bigger array to send. */
byte[] ToSend = new byte[BufferSize];

/* Change the first byte. */
ToSend[0] = IDs.ID_CHANGEBUFFERSIZE;

/* Copy the int in the ToSend. */
Array.Copy(ByteInt, 0, ToSend, 1, ByteInt.Length);

/* Sleep the thread to prevent bugs. */
Thread.Sleep(5);

/* Send the package. */
if (this._TcpClient.Connected)
{
this._TcpClient.GetStream().Write(ToSend, 0, ToSend.Length);
this._TcpClient.GetStream().Flush();
}

System.Windows.Forms.MessageBox.Show("Updated");
}

Then the server does this:
/* Handle change buffer size. */
if (_Package[0] == IDs.ID_CHANGEBUFFERSIZE)
{
/* Create the Integer array. */
byte[] IntegerArray = new byte[_Package.Length + 1];

/* Copy the array into it. */
Array.Copy(_Package, 1, IntegerArray, 0, _Package.Length - 1);

/* Clear the array so theres only the int left. */
IntegerArray = IntegerArray.Where(v => v > 0).ToArray();

/* Update the buffer size. */
_BufferSize = (int)Helper.ConvertByteArrayToInt32(IntegerArray);

/* Show message. */
System.Windows.Forms.MessageBox.Show("Buffer has been changed to: " + _BufferSize.ToString());
}

Then, I boot everything up like so:
static void Main(string[] args)
{
AFS_Network.Network.TCPServer Server = new AFS_Network.Network.TCPServer(1337);

AFS_Network.Network.TCPClient Client = new AFS_Network.Network.TCPClient("127.0.0.1", 1337, 4096);
Client.UpdateBufferSize(1239);

Console.ReadLine();
}

And the error I get is from my byte[] to int:
public static double ConvertByteArrayToInt32(byte[] b)
{

return BitConverter.ToInt32(b, 0);

}

The error is: Destination array is not long enough to copy all the items in the collection. Check array index and length.

I hope you can help me, I am sorry if it's a bit too much.

Cheers, you're the best. ;3

Assuming you had a TCP server and client.

You would have to create a buffer size like so:

// -- Convert the object client to a TCPClient.
TcpClient _TcpClient = (TcpClient)_Client;

// -- Create a stream.
NetworkStream _ClientStream = _TcpClient.GetStream();

// -- The message.
byte[] _Package = new byte[4096];

Now, problem is, let's say we want to send a bigger file to the client, perhaps, 12096? What we then have to do is tell the client that what we are about to send is bigger.

A -> B : I will send you a message of 12096 bytes
B -> A : Ok, I am ready
A -> B : [send those 12096 bytes]
B -> A : I got it

The way I am going to do it is by sending a byte array like so:

byte[] NewPackage = new byte[4096];
NewPackage[0] = ID_CHANGEBUFFER.

And then using the Array.Copy/ Methods to put the new Integer after the first byte. It's easy to get the Integer array out of it, but we will have the rest of the empty array standing there, and converting the byte array to an int again will be difficult because of the not used bytes in the array.

Yes, I did. But I can only use the array, I am using this to tell a TCP Server or Client what to change their buffer size to, and I can't send a smaller array without making it the buffer size it already has.

Many thanks to your informative answer, I will look at these links and I already have an idea on how to make it work.

Cheers! :)

It is not working, so you ask us how to make one? So you have had a reference to something that did work, otherwise you wouldn't make one if you didn't know how? What have you tried yet?

No not really. You are currently looking through my history finding something to complain about. This is probably the fourth time you have responded to an ancient old post of mine blaming me for not knowing, I was suggesting this person how to do something.

Seriously? Stop being immature.

Yeah, I actually don't mind. Sounds like a great thing to learn.

Thanks, I really appreciate the help, and I have finally gotten an idea on how to. ;)

It's funny how you are actually purposely insulting me now, I will report you now, I have asked you kindly. And no, he asked exactly what this is, and this will work for negative numbers. Cheerios.

"Naive", I hope you know what the definition means, because this is probably the third time you have insulted me on my questions.

Thanks!

Cheers man. If no other solutions, I'll choose yours.

Thanks, clear and straight to the point.

So all it pretty much does is, it uses the Font, and then disposes it after the ending bracket?

Perfect!

That's really interesting, but this uses Google and Bing already, not that it's a bad thing.

Always handy!

(Y).

Cheers!

Interesting, do they have any type of website where they explain how it works?

" System.Windows.Forms.MessageBox.Show(Angle(new Vector2(Mouse.GetState().X, Mouse.GetState().Y), new Vector2(World.Player.GetPositionX(), World.Player.GetPositionY())).ToString());" Produces NaN.

Numbers:
PlayerX = 0;
PlayerY = 0;
MouseX = 130;
MouseY = 160;

I honestly don't understand how this is not a NaN for you, as NaN is an infinite loop, so something must be wrong with your code.

"In computing, NaN (Not a Number) is a value of the numeric data type representing an undefined or unrepresentable value, especially in floating-point calculations. Systematic use of NaNs was introduced by the IEEE 754 floating-point standard in 1985, along with the representation of other non-finite quantities like infinities."

?

public void DoMouse()
{
/* Mouse State */
MouseState State = Mouse.GetState();

/* Set the Angle. */
World.Player.SetAngle(World.Player.AngleBetweenCooardinates(new Vector2(State.X, State.Y), new Vector2(World.Player.PositionX, World.Player.PositionY)));
}

This returns as NaN?

Oh, I didn't notice that there was no cursor. Anyways, my cursor is in the down left corner, and it's looking at the other side.

Cheers too!

Cheers!

Hello Matthew!
Thanks for your interesting reply. Well basically, I am trying to get it to dispose the TCP Client, because the Tcp Client is always there in the Ram even when I "disposes" or "closed" it. I'm trying it to handle the clients good enough for Windows not to complain that it still exists.
;3

Cheers mate, shame I didn't thought of that. ;3

I also understand it's 75% slow because of the huge for loop, but I have no idea on how to fix that unless I want to go back to my griddy block view. :(

Thanks for the helping reply. I'll ask another website. Really, if you can't be bothered explaining on how to use it then just let it be. This is a coding website not a insult everyone because they do not understand one thing website.

Well, since I don't know how angles work. :/

Edit: Fixed, thanks so much ! :)

Thanks, any idea on how to get the numbers 0-8 then ?
Because I need to Write the arrays. >.>

Cheers mate ! Thanks finally works !
One question, how did you know to square the number ?

This does not do what I want it to, I have checked that link out already. ;s

I am not really sure how to explain it more briefly. I got an multi-dimensional array of a 'block' class, I need to be able to convert that into a single array so I can use the XML serializer to save it in a file. I just don't know how to convert a multi into a single array and back.

I got this as a propery because that is how XML Serializer works, and I need to save this in a file and load it out later.

What do you mean ?

Also, Chunk class is similair but works.

Alright, thanks. Last problem; It does not serialize the blocks, this is my result:

"
< chunk >
< x > 0 < /x >
< y > -1< / y >
< / chunk >
"

Where are my blocks at ?

Also I changed the code of the block class to:

" [Serializable]
public static class ID
{
public static int BlockSize = 32;

public const byte BLOCK_AIR = 30;
public const byte BLOCK_DIRT = 31;
public const byte BLOCK_GRASS = 32;
}

[Serializable]
public class Block
{
public byte ID { get; set; }

public Block()
{
}

// -- Block
///

/// Initializes a new Block with the ID given.
///

/// <param name="_ID">The ID of the block.</param>
public void InitializeBlock(byte _ID)
{
// -- Set the ID.
ID = _ID;
}
}
"

It's in:

"[Serializable]
public class Chunk
{
// -- Blocks.
private Block[,] _Blocks;

// -- Cooardinates.
public int X { get; set; }
public int Y { get; set; }

// -- Chunk.
///

/// Initializes a new Chunk based on the Width and Height given.
///

/// <param name="Width"></param>
/// <param name="Height"></param>
public Chunk(int X, int Y, int Width, int Height)
{"

Don't I have that ? If not, could you point it out to me ? :)

I already have placed that ?

> Terrasylum.exe!Terrasylum.Program.Main(string[] args) Line 13 C#

Which is the main, that is why I said. There is no specific error.

Nevermind, you were right, I found a way. Thanks so much !

I also store those chunk strings in a file. ;l

I could transform the string into an array though, the chunk the player is in, to draw. ?

Well, that is the problem. I have 9 chunks loaded in, whenever the player goes into another chunk the chunks are reloaded. This is ThePlayer.LoadedChunks. It's an array of strings, and I can't make an array out of an array. :L

This, made it a lot more compact and easy thanks, unfortunatly, reading it out still seems to be messed up, am I using the right calculation(I am using the right chunk don't worry about that).

What do you exactly mean ? (Thanks for helping me out btw)

The first two for loops make sure the string has the length it needs to have, otherwise I can't change the character.

The next two loops Actually generate the landscape.

No, the thing is, they are even sizes. The Chunk has to be 20 by 20. And I am not going to make two variables valueing 20. :P

Yes, I am generating 'flat grass' and the blocks should be below half of the room, although they are spazzing all over the Room. So the problem is 'reading' out the blocks. THAT is the problem.

My problem is as I said this: "(ChunkY == 0 && j > World.ChunkSize / 2))". There is no algorithm as this is flat grass.

Someone please help.

You made my day. :)

I have no clue on what you are asking ?

@Vijay, your reply to OriginalGriff makes me think you're not serious. Please stop that behaviour.

What is your problem ?
