Unity Slider bug

Unity的slider有个bug

如果在代码里面这样设置slider

Slider.SliderEvent cb = lightnessSlider.onValueChanged;
		lightnessSlider.onValueChanged = null;
		lightnessSlider.value = l;
		lightnessSlider.onValueChanged = cb;

会在unity的UI的源码里面报错 具体为啥我也不清楚 改成下面这样就可以了

代码的含义我相信稍微认真看下就懂的

//Slider.SliderEvent cb = lightnessSlider.onValueChanged;
		//lightnessSlider.onValueChanged = null;
		lightnessSlider.value = l;
		//lightnessSlider.onValueChanged = cb;
