Hi, it’s me again 
I have found another problem:
Set the opacity of a “cc.LabelBMFont” doesn’t work . Also actions where you change the opacity doesn’t work (cc.FadeIn,cc.FadeOut,cc.FadeTo).
The return value of “getOpacity” is equal to the “setOpacity” value, but the lable didn’t change the opacity…
With best regards, Matthias
