Re: BitArray in custom class & initialize it in ctor with arguments

MarisaLovesUsAll:

Hi! I need to use array of bits in my custom class. I tried to
add std.bitmanip.BitArray as field, but got a strange error. 
What
am I doing wrong?
import std.bitmanip;
class Scene
{
     BitArray collisionMap;
     this(int w, int h)
     {
         collisionMap.init([0,0,0]);
     }
}

C:\D\dmd2\windows\bin\..\..\src\phobos\std\bitmanip.d
line 606
Error: btr cannot be interpreted at compile time, because it has
no available source code

To me this program compiles:


import std.bitmanip;

class Scene {
     BitArray collisionMap;
     this(int w, int h) {
         collisionMap.init([0,0,0]);
     }
}
void main() {}


Errors like "btr cannot be interpreted at compile time" mean that 
you are trying to run at compile-time something that can only run 
at run-time. So are you using enums or static immutables or 
static constructors or something like that?
