What the heck is a 'function(System.Array): void' Type?
I posted this a couple of months ago: I can't see a reason for this Array.Reverse() error. In brief, trying to Reverse a color array in UnityScript returned an IENumerable and I needed to convert it to an array to use it as one…
var test2 = test.Reverse().ToArray();
This was working fine but after updating to the latest version of Unity and MonoDevelop, it's now broken and I'm getting some weird errors…
First error: BCE0023: No appropriate version of 'System.Array.Reverse' for the argument list '()' was found. — Solved by removing the brackets on the end of Reverse but…
var test2 = test.Reverse.ToArray();
Second error: BCE0019: 'ToArray' is not a member of 'function(System.Array): void'. — Maybe it's converted to an Array directly in the new MonoDevelop and I don't need to convert? So I remove the ToArray() section…
var test2 = test.Reverse;
Third error: BCE0048: Type 'function(System.Array): void' does not support slicing. — So I can't access it as an array…
It seems they've changed some underlying code structure in MonoDevelop. Any ideas on a fix?
I don't know if this is a stupid question, but did you try it using LINQ?
Ooh, not a stupid question — I didn't think of that actually. LINQ does appear to work fine.
Agree with Kiloblargh comment - Reverse (without parameters) is a LINQ extension method, and you problably don't have
using System.Linq;
in your code.
I guess that without this 'using', Unity compiler thinks you want to use Reverse method of System.Array class. This is a static void method, accepting System.Array parameter, and hence the compiler errors you see.
Yep, Linq does fix the issue. Although I don't understand why it worked previously and suddenly broke.
Hmm I've just checked the tags in your question and see that you use javascript. I generally use C#, but from time to time I do some test using JS as well. I once observed, that adding import System.Linq; to any of your JS scripts works for all scripts in the project. $$anonymous$$aybe this worked in one of previous Unity versions, and now has been changed? Or maybe you simply removed the script containing this line?
Try add
using System.Linq;
