DynamicBufferElement value setting problem

Hi all.
I'm currently having a problem with my DynamicBufferElements and maybe I misunderstood something there.

I've got a component data I want to store later in my dynamic buffer:

Code (CSharp):

1. public struct TLTElementalFormData : IComponentData
2.     {
3.         public TLTElement ElementType;
4.         public int CurrentDuration;
5.         public Entity OwnEntity;
6. }

I create multiple entities for these and store them in a buffer:

Code (CSharp):

1.  
2.    var elementalFormEntity = entityManager.CreateEntity();
3.    var elementalFormData = new TLTElementalFormData() { OwnEntity = elementalFormEntity, CurrentDuration = 3};
4.    entityManager.AddComponentData(elementalFormEntity, elementalFormData);
5.    
6.    elementBuffer.Add(new TLTElementalFormDataBufferElement(elementalFormData));
7.  

Works all fine and awesome. Now the problem:
The

OwnEntity 

entity I use later for setting the

CurrentDuration

of that element:

Code (CSharp):

1.  
2.    var elementalFormData = entityManager.GetComponentData<TLTElementalFormData>(elementalFormEntity);
3.    elementalFormData.CurrentDuration -= 1;
4.    entityManager.SetComponentData(elementalFormData.OwnEntity, elementalFormData);
5.  

... which also works, but the element *in* the buffer is *not* changed.

From the entity debugger:
The entity (which is correctly changed. Note the "OwnerEntity" and "CurrentDuration")


And the buffer entity (not changed. Same OwnerEntity):



So I guess my misconception is that the buffers elements can not be "referenced" via the entity, but rather I have to get the buffer itself and alter the elements in it?

Thanks for the help,
Patrick

 

struct are values, not references. If I understood you correctly, what you want is to store only the OwnerEntity in your TLTElementalFormBufferElement and get the ComponentData from it when you need to

 

Thank you for the advice, I'll try that and see if that is working out for me.

 

That indeed worked like a charm
