I could be wrong, but it seems like slider controller is not doable using c# script in the inspector window…?
I saw some js script that does this ( like the ones in the post processing script ) but even there , I could not figure out what makes some float value to include its own slider controller and some not.
I know you can do this in custom editor window, but I want it to be just straight foward on the inspector window where my script component shows. This is possible for custom shader, so why not for c# and is this possibility at all?
Sliders work for me in the inspector. As far as I know, all the editor scripts from Unity are implemented in C#. I don’t see a reason why anything that can be done in JavaScript can not be made with C#.
Usually, if something works in a custom editor window, it should also work in the inspector.
It would help, if you could share some code of things that are not working for you.
The only thing you need to do with it is to translate it to C#. But there are lots of other examples that you may use as a starting point, such as that one.
