How to Fix Error! CS0052: Inconsistent accessibility on NativeArray! Help pls

Hello, i'm super new to unity 1 and c# 1 week and i'm actually following a Youtube video tutorial on how to make a TowerDefense game, the thing is i'm getting a error that i do not know how to resolve.

"

Code (CSharp):

1. public struct MoveEnemiesJob : IJobParallelForTransform
2. {
3.     [NativeDisableParallelForRestriction]
4.     public NativeAray<Vector3> NodePositions;
5.  
6.     [NativeDisableParallelForRestriction]
7.     public NativeAray<float> EnemySpeed;
8.  
9.     [NativeDisableParallelForRestriction]
10.     public NativeAray<int> NodeIndex;
11.  
12.     public float deltaTime;
13.  
14.     public void Execute(int index, TransformAccess transform)
15.     {
16.         if (NodeIndex[index] < NodePositions.Length)
17.         {
18.         }
19.         Vector3 PositionToMoveTo = NodePositions[NodeIndex[index]];
20.         transform.position = Vector3.MoveTowards(transform.position, PositionToMoveTo, EnemySpeed[index] * deltaTime);
21.  
22.         if(transform.position == PositionToMoveTo)
23.         {
24.             NodeIndex[index]++;
25.         }
26.      
27.     }
28.  
29. }

i'm getting this 3 errors

1 *

the video i'm using in this case is

16:10

 

This sounds like a jobs thing, and I'm not even sure of the jobs subsystem stability or state... is it still preview or release? Does this video use the preview or the release? Try and match whatever they're using I guess, but it's also likely tightly bound to the version of Unity you're on.

If you just want to make a TD game, the last thing you need is the jobs system... find a tutorial that just does it "vanilla," none of this uber-high-tech future stuff. If you need to then have ten billion units attacking at once, then yeah, perhaps look into jobs.

 

Yeah it's from unity jobs, that's in resources now, i've had a hard time to discover that kkk, but thank you for the tip, the game is just 1 map 50 enemies and 50 waves each one using one enemy, so not that many units probably nothing above 500 hundred at the same time
