How should I move in a DList ?
Hello, As I am totally new to D (my background is mainly C++) I am having trouble porting an algorithm that simplifies a polyline in 2D, very similar to this one: http://psimpl.sourceforge.net/reumann-witkam.html Here is what I would like: 1) Use a doubly-linked list, preferably one from a standard library (I need fast insertion/removal anywhere inside the list). 2) Have multiple "cursors" (ref to a list node, pointers, iterators etc.) that I move forward in my list when needed. 3) Remove and add some elements in the list (at/between "cursor" positions). I am fine with having "unsafe" code for this example (the function is 43 lines long in C++, does not have too many cases and would be tested on a lot of data). What "cursor" should I use to get something similar to C++'s std::list's iterators, or C#'s LinkedListNode that I was able to use to port the algorithm in C++ and C# ? (I am benching languages). Thanks in advance,

I wondered how I would be able to make an OpenGL-based Engine in D, what libraries would I need? Your help will be much appreciated! - NCPlayz I use BindBC-OpenGL for my game engine. To handle windows and input you can either use BindBC-GLFW (like me) or BindBC-SDL2. It's very nice and easy. I hope it helped. Good luck!
Address problem
Hi,
---
interface I { }
I[string] i;
class C : I {
this() {
i["s"] = this;
foreach (_i; i) {
writeln(&_i);
}
foreach (ref _i; i) {
writeln(&_i);
}
}
}
void main() {
C c = new C;
writeln(&c);
}
---
output:
19FDD8
2802028
21FE58
---
I need that I["s"] to have the same address like c.
