Thanks. It's working. Seems like either it was the drawing code
or the setting one of the setup conditions.

Ah, so it's about lvalues an rvalues, not the type of the range.
Makes sense now.

You can specialize on templated structs generically.
int foo(T : Bar!(X, Y), X, Y)

Hi All,
What is the difference between std.algorithm.reduce and

Mir's reduce works on Slices whereas Phobos's reduce works on
Arrays/Ranges.

Is there anyway to extend an existing function to accept custom
data types?
Option 1 - global import of std.math
import std.math;
struct Custom {}
int signbit(T)(T x) if (is(T == Custom))
{
return 0;
}
Custom c;
assert(signbit(c) == 0);
assert(signbit(-1.0) == 1);
I do build a string by coping large parts of diffrent buffers,
all those buffers live after the functional call, so rather than
duplicate those string I'd like to copy only references to those
parts rather duplicate every string. I combined appender!string,
assumeUnique() and array slices.
of course a totally different approach to solve this is welcome,
I came from C/C++/C# worlds so I'm in the process of slowly
converting my thinking to the D way (which is new for me, since
I'm even unifamiliar with python and such, which got such
friendly syntax)

Hi Adam, I'm interested in using your simpledisplay for 3D in
openGL. I have worked with 2D fine but 3D is problemattic. I
cannot get any depth even though i have set up 3D mode by
modifying gamehelpers:
SimpleWindow create2dWindow(int width = 512, int height = 512,
int viewportWidth=512,
