Question Looking for somthing similar to .WithChangeFilter<>() but for removed components

Hello everyone,

my code is heavily based on reactions for component changes. WithChangeFilter<>() works great for adding and changing components. But it obviously doesn't work for removed components

Is there a way to detect remove of a component? Maybe something like this

Code (CSharp):

1.             Entities
2.                 .WithAll<Item>()
3.                 .WithNone<IsActive>()
4.                 .WithRemoveFilter<IsActive>()
5.                 .ForEach((int entityInQueryIndex, Entity entity) =>
6.                 {
7.                     ....
8.                 })
9.                 .WithStructuralChanges()
10.                 .Run();

I am aware of ISystemStateComponentData, but I am looking for more elegant solution

 

You'll need a reactive system for that :
