Can't Build with the MinMaxSlider

[dfarjoun]

Hi,

This is an amazing solutions for my needs, but I can't Build the project.

It was all working great inside the editor, but when I tried to export I got these errors:

Library/PackageCache/com.guciodevs.simple-min-max-slider@46ff35d229/Scripts/MinMaxSliderAttribute.cs(6,18): error CS0509: 'MinMaxSliderAttribute': cannot derive from sealed type 'PropertyAttributes'

Error building Player because scripts have compile errors in the editor

Build completed with a result of 'Failed' in 3 seconds (3102 ms)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr) (at /Users/builduser/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:197)

Can you help solve this issue?

Issue still seems to exist in Unity 2021.1.7f1:

Library\PackageCache\com.guciodevs.simple-min-max-slider@46ff35d\Scripts\Editor\MinMaxSliderDrawer.cs(6,35): error CS0246: The type or namespace name 'PropertyDrawer' could not be found (are you missing a using directive or an assembly reference?)

I solved this by using the UnityPackage instead of the UPM github link, and then had to manually move "MinMaxSliderDrawer.cs" to the Editor folder in the root of my project.

@TylerTemp @WoutStandaert I forked the repo and fixed this issue last year but the pullrequest has not been implemented. I think the owner of this repo is not monitoring any more. Feel free to use my repo instead. https://github.com/Adamcbrz/SimpleMinMaxSlider

The issue is tha all those API's are Editor only and won't be avaiailbe in a build. They need to be wrapped in a UNITY_EDITOR preprocess directive.
