Question Pointer to component data

I'm looking to have one entity reference another entity's component data, currently I store the target entity in a component, then use GetComponent to get that entities data. Is it possible to store a reference to the target entity's component data in a component so I don't have to use GetComponent?

 

Not persistently. Whenever a structural change happens, entities and their components can be shuffled around in memory.

 

So the most efficient way to do this would be to have a reference to an entity and use GetComponent every time you want to get the component?

 

You can save pointer references but you need to check for chunk.DidOrderChange for the archetype and then update all references from the chunk. Even if just one changes, you'll never know which one.

 

There are several different APIs to do effectively the same thing in different contexts. But that's the idea.
