Question

I have a pause button/method(not the greatest but it works). Currently, I am changing the opacity of EVERYTHING on screen when it is paused which is not what I want to do but it works(and is a pain). Does anyone have a better way of changing the brightness of everything on screen at the same time?

E.G.
when you pause “Angry Birds”(only game I could think of at the moment) the main scene has a transparent black overlay on it.

Here is my Code

-(void) Pause:(ccTime)delta
{
    Bag.opacity = 150;
    ScoreH.opacity = 150;
    TimerH.opacity = 150;
    leftB.opacity = 150;
    rightB.opacity = 150;
    bg.opacity = 150;
    scoreLabel.opacity = 150;
    timeLabel.opacity = 150;

    [[CCDirector sharedDirector] pause];

    CCLOG(@"Game Paused");
}

Also, most of my sprites come from sprite sheets. I don’t know if that helps.
Any help is greatly appreciated. Thanks in advance!

Wow… I have been looking for an answer for this for about a month and RIGHT after I ask this question I decide to search it again and… I find it.

Please excuse my stupidity…

CCLayerColor* colorLayer = [CCLayerColor layerWithColor:ccc4(0, 0, 0, 100)];
[self addChild:colorLayer z:0];

The first three numbers are “RBG” colors and the last number is opacity.

Answer 1

To put a color overlay on top of a layer just add..

CCLayerColor* colorLayer = [CCLayerColor layerWithColor:ccc4(0, 0, 0, 128)];
[self addChild:colorLayer z:0];

The first three numbers are “RGB” colors and the last number is opacity. Each can have a value in range between 0 and 255.

E.G.

layerWithColor:ccc4(Red, Green, Blue, Opacity)
