setDrawColorFloat method

bool setDrawColorFloat(
  1. double r,
  2. double g,
  3. double b,
  4. double a,
)

Set the color used for drawing operations (Rect, Line and Clear).

Set the color for drawing or filling rectangles, lines, and points, and for SDL_RenderClear().

\param renderer the rendering context. \param r the red value used to draw on the rendering target. \param g the green value used to draw on the rendering target. \param b the blue value used to draw on the rendering target. \param a the alpha value used to draw on the rendering target. Use SDL_SetRenderDrawBlendMode to specify how the alpha channel is used. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
