Hi,
Is there any tutorial on how to create custom user interface for an extension liike PlayMaker, uFrame etc. have?
Do I have to do it in onGui of editor window? If so how can I compile it to dll with resources like icons and so on.
Thank you.
Everything you see in Unity is made using the Unity EditorWindow class. This includes the standard stuff and any custom tools that 3rd parties have made. There are a ton of tutorials online about creating editor windows. Everything they do (for the most part) you can do right out of the box. Just do a quick google search and you will see a ton of Unity Editor tutorials.
As for compiling you code you do not have to. This is a step taken by some but it requires a lot more experience if you want to debug your code. It suggested that you keep your code in your project until you have it working.
Cheers,
