I was wondering how difficult it would be to use NetBeans and if you could get it to recognize the Unity API so that you could see fields and functions that are available for an object.
It's a different language for a different platform.
If you want autocomplete, you have other options:
- Wait for Unity 3, as the still-in-progress MonoDevelop supports UnityScript as a first-class language.
- While it is out, you can use FlashBang Studios' UnityDevelop, which is Windows-only.
UnityDevelop is not supported and might not be actively developed, but since you only need it until Unity 3 you probably will be fine.
