Bug Entity Version / LinkedEntityGroup, Version does not get counted up

I don't have time atm to create a minimal example, but on the latest version I have the following problem:

Code (CSharp):

1.  
2.  
3.                  var entityGroup = buffer.AddBuffer<LinkedEntityGroup>(worldEntity);
4.                 // Workaround? First entities version get counted up to 2...
5.                     var workaroundEntity = buffer.CreateEntity();
6.                     entityGroup.Add(new LinkedEntityGroup()
7.                     {
8.                         Value = workaroundEntity
9.                     });
10.  
11.                     for (int dx = 0; dx < world.width; dx += 1)
12.                     {
13.                         for (int dy = -world.depth; dy < world.height; dy += 1)
14.                         {
15.                             for (int dz = 0; dz < world.width; dz += 1)
16.                             {
17.                                 var chunk = buffer.CreateEntity();
18.                                 entityGroup.Add(new LinkedEntityGroup()
19.                                 {
20.                                     Value = chunk
21.                                 });
22.                             }
23.                         }
24.                     }

Later on different frame:

Code (CSharp):

1. buffer.DestroyEntity(worldEntity);

The first entity created in the buffer has its version set to 2.
all others are set to 1.
LinkedEntityGroup contains all entities with version 1.

When destroying the parent, only the entities with version 1 are getting destroyed.

I actually have no idea how/when the version gets counted up. But since I never do anything with the workaroundEntity it seems like this is a bug.

might also have to do with the buffer

 

I'm not sure I understand what you are doing, but I know that the first entity in the LinkedEntityGroup should be worldEntity itself.

 

I dont think what you are saying is right, the Buffer is on the worldEntity in this case and the children inside the buffer

 

Unity's convention is that the first entity in a LinkedEntityGroup is the entity the buffer is attached to, followed by all of that entity's linked children and their children and so on. It is not the most intuitive, but it is what it is.

 

Where is that documented, and if that is the case then it is bugged in other ways cause I don't do that and it still works

I can't find any examples for that

 

it is 100% that LinkedEntityGroup should contain 1st element as entity itself. You can inspect EntityManager.DestroyEntity and it will search for LinkedEntityGroup and if manager will find this buffer then it will iterate through buffer only

 

yes you are right :+1 maybe sth for the documentation thanks for the help
