"Identifier Expected" Error on an enum inside a struct

I haven't worked much with structs or enums, but after having a look at a couple of tutorials, I thought they were quite easy. I thought about setting an enum inside a struct, such as for chunk manipulation with a 2d array of an enum, but for some reason it says I need a comma in the middle of the variable I'm setting!

Code (CSharp):

1. [Flags]
2. public enum WallState
3. {
4.     LEFT = 1,
5.     RIGHT = 2,
6.     UP = 4,
7.     DOWN = 8,
8.     VISITED = 128,
9. }
10.  
11. public struct Chunk
12. {
13.     public WallState[,] Walls;
14.     public Position ChunkPosition;
15. }
16. // ^ struct and 2d enum array
17.  
18. public static Chunk[,] ConvertToChunk(WallState[,] maze) {
19.         Chunk[,] out = new Chunk[3,3]; // <<<< error line
20.         for (int x = 0; x < 3; x ++) {
21.             for (int y = 0; y < 3; y ++) {
22.                 WallState[,] temp = new WallState[5,5];
23.                 for (int xc = 0; xc < 5; xc ++) {
24.                     for (int yc = 0; yc < 5; yc ++) {
25.                         temp[xc,yc] = maze[x*5+xc,y*5+yc];
26.                     }
27.                 } // << apparently need another?
28.                 out[x,y] = new Chunk{ Walls = temp, ChunkPosition = new Position{ X = x, Y = y } }; // need a } after out[x,y]....
29.             }
30.         }
31.     }
32. //I'm getting an error for some reason right after I declare Chunk[,]...
33. //I'm also getting an error that I need a semicolon instead of =...
34. //

 

out is a keyword in C#. Call your variable results or something instead.

 

Sorry, right after sending this I saw that 'out' was highlighted, and I completely forgot it's technically not usable as a variable. I've changed the line to

Chunk[,] chunkOut = new Chunk[3,3];

and it works. Funny how VSCode didn't highlight that for me...

 

It does indeed do that from time to time, plus sometimes it is ultra-laggy before it highlights / helps you.

The most common fastest fix is just the whole Assets -> Open C# Project from within Unity. And if you need more, here's my standard blurb:

This may help you with intellisense and possibly other Visual Studio integration problems:

Sometimes the fix is as simple as doing Assets -> Open C# Project from Unity. Other times it requires more.

Also, try update the VSCode package inside of Unity: Window -> Package Manager -> Search for Visual Studio Code Editor -> Press the Update button
