Feature Request Dynamic Buffers and EntityCommandBuffer

Hello Unity Team,

is it possible to add an API, so users can use ecb.AppendToBuffer to add an item to the existing buffer or add a buffer to the entity if doesn't exist and append the elements.

Thanks!

 

I second this. It would save us from adding a BufferFromEntity to the job just to do that check and call different ECB functions based on the presence of it

I'd also love if there was some in-IDE documentation for most ECB functions, telling us what happens in these cases. It could save us from having to make little tests to find out (or having to look at the sources)

For example:

• what happens when calling RemoveComponent and the component isn't there (is it an error, or is the action just skipped?)
• what happens when calling AddComponent but the component is already there (does it overwrite the component, or just skip?)
• what happens when we SetComponent but the component isnt there
• what happens when calling AppendToBuffer but the buffer isn't there
• what happens when calling AddBuffer but a buffer is already there (with elements in it). Does it clear the buffer, or skip?
• etc...

I already know the answer to all of these, but it would be a nice QoL addition if we could get all that info just by hovering over ECB functions in the IDE. Sometimes I'm not sure if I remember well

 

Call this, then call AppendToBuffer(). No checks required.
