I vary rarely use Windows API so I can't help you there pal.

You missed my terrible joke. That's the error GCC gives me when I try to compile an empty file.

[Valid_Dark]

ohh,... yeah,
that was a pretty terrible joke.
I don't think I've EVER tried to compile an empty file,. I mean... why would you??
(other than for terrible jokes that is)

Back before C++11, stringstream got a lot of abuse from me, since the to_string function didn't exist.

Code: (Actual code from one of my utility headers) [Select]

template<typename T> string toString(T data) { // Will fail to compile if operator<< isn't defined for the type.
    stringstream sstr(""); // yeah, explicit initialization to a blank string isn't necessary, but I still do it
    sstr << data;
    return sstr.str();
}

x=24;
name<<"string"<<42<<"string"<<x;
name.str is how you'd call the string, so
cout>>name.str(); should output  "string42string24"

In Java, you'd type
System.out.println("string" + 42 + "string" + x);
to output that.

Does the '+' operator do anything for strings in C++?

const const double*& strangeType();,

That makes me wonder how many times you can fit const into a single c++ statement.

This is a good reference that I use: http://jriddell.org/const-in-cpp.html

const int*const mymethod(const int*const&)const

It will return a pointer which is constant and points to a constant integer, the method doesn't alter either the variable pointed to by the paramater or the pointer itself and it doesn't alter any of the member variables of the object the method is it.

Although, I suppose if you used templates it could go on forever:

Code: [Select]

template<const int A , const int B , const int C> const int* const mymethod(const int* const&) const
But wouldn't those consts be redundant, since template parameters have to be constant anyway?

AHA I knew I wasn't crazy, I didn't think it existed before c++ 11, but a quick google didn't show anything about it.  My compiler doesn't support c++ 11 which would explain why I've never used it.

Yes, see my previous post.  But in c++ you cant add a variable or a number to a string unless they are converted into a string first, and converting them to strings is a headache (before C++ 11 existed)


And mr.Skyrunner, I would like to see your triangle water code maybe if it wouldn't be a bother to you.

I'll happily link Qt into any application I make, even if it's just for QStrings. All the convenience rolled into one.

It concatenates string objects. The issue is, it *only* concatenates string objects. By extension, it will also work with anything that can be implicitly cast as a string, which, in the standard, is all of one* thing: char arrays. User-defined classes that define implicit casting to string will also work. So, more function calls are needed to concatenate data of other types.

*I'm not 100% familiar with C++11, so I'm not sure if char initializer lists can be implicitly converted to strings or not.

Which is one of the nice things in C#, everything has a .ToString() implementation.

Also Java. It just doesn't always do what you want.

[Valid_Dark]

been working most of the day on the backend of a heightmap generator,
so far it's not giving me the results I had hoped for.

using a version of the diamond square algorithm,
it IS working, just not right, with some fine tuning I think I can get it working nicely.

[GalenEvil]

@Valid_Dark: Try putting the values at all four corners before starting the Diamond-Square Algorithm. It looks like you are not setting up the map corners and clamping to a byte value which would give a large possibility of seeing what you just showed, most of the values trying to move into negative space and it clamping the values to zero.

[Valid_Dark]

I wanted all of the edges to be 0,
I'm making a fair amount of progress,
I just thought I'd share these with you.

Spoiler: "First Attempt" (click to show/hide)

Spoiler: "Not quite what I was going for, but looks pretty cool" (click to show/hide)

lol tried to fix the lines and made them worse, but it looks pretty cool

Spoiler: "Too many islands" (click to show/hide)

Spoiler: "This is more like what I was going for" (click to show/hide)

Not asking for help, just showing you guys what I'm up to.

Edit: ok, I'm still having an issue with the lines, I'm thinking I might make a smoothing function, and have it run over the whole map and just smooth everything out, how do you think that sounds?

Spoiler: "The lines are rarely noticeable when I set it to 2 tone (click to show/hide)

each pixel in these images are going to be 32x32 tiles.

[Skyrunner]

The lines seem to tell me that you implemented the algorithm in a less-than optimal way. When I did my version, it had no line artifacts.

How are you doing the algorithm? Recursive, iterative? Clamped to a grid every step? There was some source code I saw a long time ago that used floating points (probably not the right terminology) instead of ones clamped to grids...
