Re: unsigned byte color!

Hey Tom,

 

My mistake, anyway you put it, both should be the same.

 

AFAIK, unsigned char (int8) on windows doesn’t seem to be supported, is there any known workaround, can a .def() include a static cast for instance?

Not to sound stupid, but why does your lua say:

myColor= Color4i(255, 0, 0, 100);

according to the luabind registration code, it should just be...

myColor=Color(255,0,0,100);

And lua internally supports plain ol' intergers ( int32 ...ok depends on platform but you get the point...)

so no matter what happens, this is likely going to be cast at runtime.  have a look at the c api for details as to the very minimal types supported w/in lua.

Hello everyone,

 

Any particular reason why Luabind is choking on UChar?

 

.cpp

 

typedef unsigned char UChar;

 

class Color

{

      public:

 

            UChar r, g, b, a;

 

            inline Color(UChar in_r, UChar in_g, UChar in_b, UChar in_a):

                  r(in_r),

                  g(in_g),

                  b(in_b),

                  a(in_a) {}

 

                  ///SNIP...

}

 

Luabind

 

module(in_lua)

[

      class_<Color>("Color")

      .def(constructor<UChar, UChar, UChar, UChar>())

];

 

.lua

 

myColor= Color4i(255, 0, 0, 100);

 

result: No matching overload found

 

If I repalce every UChar by a float it does work… hummm… hocus pocus…
