because I want to use the slider. I got some compile errors which confused me, but I got it to compile.
Now I get a runtime error. CCControlSlider::spriteScale is zero, causing a NaN.
What confuses me is, that I can not find any line, where CCControlSlider::spriteScale is initilized or event set.
Now I am wondering, am I using the correct version of cocos2d-x-extension, should I get it somewhere else?
