Question

How to make transparent Background in CCGLSurfaceView / CCLayer ( cocos2d-android ) ?

I tried to change the superclass to CCColorLayer and set the color to ccColor4B.ccc4(0,0,0,0), but didn’t work.

Also, I tried to set the background color to android.R.color.transparent, but it is still opaque.

Answer 1

CCLayer should be transparent [no background] by default
you should have a CCScene behind it with a background that will show, like this

public MainScene{
    super();
    CCSprite bg = CCSprite.sprite("MainBG-gl.png", true);
    CGSize screen = CCDirector.sharedDirector().winSize();
    bg.setPosition(CGPoint.ccp(screen.width / 2, screen.height / 2));
    addChild(bg);
    layer = new MainLayer();
    addChild(layer);}

that’d be the constructor of your CCScene where MainLayer is your CCLayer that you wanna use [bg is the background obviously]
