<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Not quite sure if I understand your question - but here is a possible<br>
answer;<br>
each grid should have a method entityPointer which takes a seed and <br>
returns the corresponding EntityPointer so something like<br>
EntityPointer ep = grid.entityPointer( seedVector[i] );<br>
const Entity &entity = *ep;<br>
should do what you want. <br>
<br>
If you find the documentation not sufficient, a patch would be welcomed!<br>

Hi all,<br>
<br>
I'd have a question for you about EntitySeed.<br>
In a previous message I was told that the best and most efficient way of storing information about elements is through EntitySeed.<br>
>From what I read from the documentation, they are "seeds" that help you retrieve the necessary information about an element you could need at a later stage, minimising the memory waste. Am I right?<br>
<div><br>
<div style="font-family: Tahoma; font-size: 13px;">Now, suppose you have classified your elements in two different categories, liquid/solid for example; I can't store the physical Entities in a container, I can only store pointers of them, or seeds of them.<br>
How do I "recreate" the entity, given its seed? Would it be possible to "recreate" an EntityPointer from the EntitySeed?<br>
My question comes from the fact that I need to "filter" the list of elements and discard some of them (e.g., the solid ones), but in order to do that I need to use a method "find" for a STL container, and the operands (element to find and entries of the container)
have to be, of course, of the same type.<br>
<br>
Thanks a lot in advance!<br>
<br>
Andrea<br>
