What are you working on? November 2011 Edition

[QUOTE=FlashStock;33341579]try
while (sw.Peek() >= 0)
{
input = sw.ReadLine();
}[/QUOTE]

That just returns "0, 0, 0, 0, 0, 0, 0, 0, 0, 0, etc"

[QUOTE=Loli;33341644]That just returns "0, 0, 0, 0, 0, 0, 0, 0, 0, 0, etc"[/QUOTE]

Try this:

[cpp]String buffer;
while ( ( buffer = sw.ReadLine() ) != null )
{
// do stuff
}[/cpp]

You should also wrap the StreamReader in a BufferedReader for more efficient reading of lines. Additionally it is not necessary to allocate the string array in advance, as the String.split function will allocate one for you.

Your final code will be something like this:

[cpp]if (File.Exists("tilemap.txt"))
{
StreamReader sw = new StreamReader("tilemap.txt");
BufferedReader reader = new BufferedReader(sw);

String buffer;
String[] data;

while ((buffer = reader.ReadLine()) != null)
{
data = buffer.Split(',');

for (int Y = 0; Y < 32; Y++)
{
mTileMapData[i, Y] = Convert.ToInt16(Data[i]);
}
}

reader.Close();
}[/cpp]

[QUOTE=Loli;33341294]Working on mah comp entry... Could anybody help me fix this?

            if (File.Exists("tilemap.txt"))

                string input = "";
                string[] Data = new string[48];


                for (int i = 0; i < 32; i++)
                    Data[i] = "0";
                
                for (int i = 0; i < 48; i++)
                {
                    input = sw.ReadLine();
                    Data = input.Split(',');


                    for (int Y = 0; Y < 32; Y++)

It throws this error:

Split returns null if you try to split a string with a character the string doesn't contain.

You sure all the lines contains a ','?

Rendering Code:

            {
                for (int x = 0; x < 48; x++)
                {
                    spriteBatch.Draw(mAsset, mCamera + new Vector2(32 * x, 32 * y), new Rectangle(32 * mTileMapData[x, y], 0, 32, 32), Color.White);
                }
            }

I can't just flip the X and Y either because it won't fit in the array.

I had an idea about a top down shooter game where explosions actually work the way they are supposed to. So I made a pressure simulation thing.
[video=youtube;vEGfs9RNMM4]http://www.youtube.com/watch?v=vEGfs9RNMM4[/video]

[Overv]

Yeah, that's because your reading method is wrong. Your file has a row on every line, that means the Y value of every line is fixed and the X is variable. For example:

0 1 2 1
0 3 4 1
1 5 3 2

( 0, 0 ) = 0
( 1, 0 ) = 1
( 2, 0 ) = 2
( 3, 0 ) = 1

( 0, 1 ) = 0
( 1, 1 ) = 3
( 2, 1 ) = 4

...

This is what you did in your first example:

[cpp]for (int i = 0; i < 48; i++)
{
input = sw.ReadLine();
Data = input.Split(',');

for (int Y = 0; Y < 32; Y++)
{
mTileMapData[i, Y] = Convert.ToInt16(Data[i]);
}
}[/cpp]

Here you assume that on a single line in your input file, every coordinate has a variable Y coordinate and the X coordinate is fixed. This is of course, the other way around. That's why lines in your render appear vertical instead of horizontal.

Well in theory, if I did it well it would allow for interesting level design.
For example, lure a large group of enemies into a narrow dead end, then throw a pressure grenade and watch them all be blown out of the tunnel.

I think game devs consistently underestimate what players notice.

When a game has shitty grenades with shitty ways of hit detection/how far they hit/etc. I notice. It'd be really really cool to me to like throw a high explosive in a small room and watch a bit of flame lick out the doorway or something like that, instead of some generic circle.

I only use var when either the type is unambiguous, like when creating an object with new, or the type is too damn long to type. I wouldn't replace int or string with var.

Well after using C# so long I don't even see the places I used them as ambiguous. Length is always int, ReadLine is string, Split is string[].

Anyways intellisense is a huge part of .net development. I recommend using at least monodevelop or sharpdevelop.

Sure, you can hover over the names for intellisense to tell you what they are, but it's so much easier to just glance up at variable names (especially since people rarely use hungarian notation anymore) to see what they are. I think it's easily as important as having good variable names

var ages = People.Select(p => p.Age);

Is ages IEnumerable<byte/short/int/long>?

Well after using C# so long I don't even see the places I used them as ambiguous. Length is always int, ReadLine is string, Split is string[].

Anyways intellisense is a huge part of .net development. I recommend using at least monodevelop or sharpdevelop.[/QUOTE]

Relying on intellisense to make your code readable is perhaps the silliest thing I've ever heard. Plenty of devs use flat text file editors + make etc.
