But label component can’t set start alpha.

Are you sure? There shouldn’t be a difference between the two platforms. Does nothing happen in html5?

#3

Yes.
I try again this code

go.set("#label", "color", vmath.vector4(0, 1, 1, 0.5))

Thanks. It could be something in the font shader.

HTML5 target is more picky about ints vs floats in its shaders, generally best to stick with floats. Even when you want to zero something out so 0. or 0.0 for clarity. That would mean floats for all values too. Check the console to see if there is any warning about that.

I didn’t have discover warning about float values.
But because of using gui attached label can control alpha of label on the editor,
so my problem may be solved.
I will return my game development.
Actually,this is my first time experience to question in English.
