Question

I try to add a layer whose all purpose is to fill the entire scene with the white color.

I try doing it as follows :

// Inside a cass which extends CCScene
- (id)init {
    if (self = [super init]) {                    
        // Create the flash layer on level restart
        _flashLayer = [[CCLayerColor alloc] init];
        [_flashLayer setColor:ccc3(255, 255, 255)];
        [self addChild:_flashLayer z:0];
        [_flashLayer release];        
    }

    return self;
}

Problem is that I get a black screen no matter how I set the color of the layer.
Another thing, if I try to create the layer as follows :

 _flashLayer = [[CCLayerColor alloc] initWithColor:ccc4(255, 255, 255, 255)];

I get the following error :

Incompatible type for argument 1 of 'initWithColor:'

I looked in the source and everything seems to be as expected.

Can anyone shed some light on this issue ?

Thanks.

You have two choices:

_flashLayer = [[CCLayerColor layerWithColor:ccc4(255, 255, 255, 255)];
[self addChild:_flashLayer z:0];

or

// the key is to add (CCLayerColor *) to cast
// or you will meet 'incompatible type for argument' error at compile time
_flashLayer = [(CCLayerColor *)[CCLayerColor alloc] initWithColor:ccc4(255, 255, 255, 255)];
[self addChild:_flashLayer z:0];
[_flashLayer release];
