ttfSetTextColorFloat function ttf

bool ttfSetTextColorFloat(Pointer<TtfText> text, double r, double g, double b, double a,)

The default text color is white (1.0f, 1.0f, 1.0f, 1.0f).

\param text the TTF_Text to modify. \param r the red color value, normally in the range of 0-1. \param g the green color value, normally in the range of 0-1. \param b the blue color value, normally in the range of 0-1. \param a the alpha value in the range of 0-1. \returns true on success or false on failure; call SDL_GetError() for more information.
