Does any1 have smart suggestions on how to convert a format of RGBA(floats) to an unsigned int? The colours work like opengl with 1.0f being 255(full entensity) and 0.0f being no intensity. So i have R = 0.5f; G = 0.5f; B = 0.5f; A = 0.5f; And then if i convert this i should get R G B A 0x3F3F3F3F So i need a function like unsigned int color = GetColor(0.5f,0.5f,0.5f,0.5f); Thanks

Nevermind i got a solution, i dont know how fast or efficient it is but here:

unsigned int GetColor()
{
return ((unsigned int(255.0f*a)) << 24) + ((unsigned int(255.0f*r))<< 16) + ((unsigned int(255.0f*g))<< 8) +(unsigned int(255.0f*b));
};
