Question

// Add Game Status Label

String test="Tap Tiles to Begin";       
CCBitmapFontAtlas statusLabel = CCBitmapFontAtlas.bitmapFontAtlas(test, "bionic.fnt");
statusLabel.setScale(1.3f* generalscalefactor); //scaled
statusLabel.setAnchorPoint(CGPoint.ccp(0,1));
statusLabel.setPosition( CGPoint.ccp( 25* generalscalefactor , screenSize.height - 10* generalscalefactor));
addChild(statusLabel,-2, STATUS_LABEL_TAG);

，错误是
