Attempting to set shape color to blue gives black

[Bill_n]

I can set the background displayed to blue just fine using Clear(sf::Color(0,0,255)).

I'm trying to set a shape's color to blue by using the Shape::SetColor method as follows:

Code: [Select]

crit.getShape().SetColor(sf::Color(0,0,255));

crit is an object that has a sf::Shape member variable, accessed by the following function:

Code: [Select]

sf::Shape& Critter::getShape()
{
return shape;
}

and shape is instantiated in the object's constructor as follows:

Code: [Select]

shape = sf::Shape::Circle(0, 0, 15, sf::Color(128, 128, 0, 255));

When I try to set the shape's color to blue, it yields a black circle. If I set it to (0,0,255,123) it yields a grey circle when viewed against a white background.

Is there some blending mode of the Shape that is interfering with my attempt?

(255,0,0) yields red    
(0,255,0) yields green
(0,0,255) yields black  :?:
(255,255,0) and (255,255,0) both yield yellow  :!:
This seems to indicate to me there's some sort of masking going on that is ignoring blue component, but i have no idea where to look for this

The color that you pass to the Shape::Circle function is assigned to the shape's points. This is not the global shape color (inherited from sf::Drawable), these two are separate and modulated when the shape is drawn. So you should leave the shape's points with a white color, and play only with the global color (SetColor).

OK, thanks for the clarification. It's a bit confusing because the Circle constructor's color argument is just described as "Color used to fill the circle" in the docs.

I know, I should add something to the doc to make it less confusing
